Pregnant Travelers

Pregnant travelers can generally travel safely with appropriate preparation. But they should avoid some destinations, including those with risk of Zika and malaria. Learn more about traveling during pregnancy and steps you can take to keep you and your baby healthy.

Before Travel

Before you book a cruise or air travel, check the airlines or cruise operator policies for pregnant women. Some airlines will let you fly until 36 weeks, but others may have an earlier cutoff. Cruises may not allow you to travel after 24–28 weeks of pregnancy, and you may need to have a note from your doctor stating you are fit to travel.

Zika and Malaria

Zika can cause severe birth defects. The Zika virus is spread through mosquito bites and sex. If you are pregnant, do not travel to  areas with risk of Zika . If you must travel to an area with Zika, use  insect repellent  and take other steps to avoid bug bites. If you have a sex partner who lives in or has traveled to an area with Zika, you should use condoms for the rest of your pregnancy.

Pregnant travelers should avoid travel to areas with malaria, as it can be more severe in pregnant women. Malaria increases the risk for serious pregnancy problems, including premature birth, miscarriage, and stillbirth. If you must travel to an area with malaria, talk to your doctor about taking malaria prevention medicine. Malaria is spread by mosquitoes, so use  insect repellent and take other steps to avoid bug bites.

Make an appointment with your healthcare provider or a travel health specialist  that takes place at least one month before you leave. They can help you get destination-specific vaccines, medicines, and information. Discussing your health concerns, itinerary, and planned activities with your provider allows them to give more specific advice and recommendations.

Plan for the unexpected. It is important to plan for unexpected events as much as possible. Doing so can help you get quality health care or avoid being stranded at a destination. A few steps you can take to plan for unexpected events are to  get travel insurance ,    learn where to get health care during travel ,  pack a travel health kit ,  and  enroll in the Department of State’s STEP .

Be sure your healthcare policy covers pregnancy and neonatal complications while overseas. If it doesn’t get travel health insurance that covers those items. Consider getting medical evacuation insurance too.

Recognize signs and symptoms that require immediate medical attention, including pelvic or abdominal pain, bleeding, contractions, symptoms of preeclampsia (unusual swelling, severe headaches, nausea and vomiting, and vision changes), and dehydration.

Prepare a  travel health kit . Pregnant travelers may want to include in your kit prescription medications, hemorrhoid cream, antiemetic drugs, antacids, prenatal vitamins, medication for vaginitis or yeast infection, and support hose, in addition to the items recommended for all travelers.

During Travel

Your feet may become swollen on a long flight, so wear comfortable shoes and loose clothing and try to walk around every hour or so. Sitting for a long time, like on long flight, increases your chances of getting blood clots, or deep vein thrombosis. Pregnant women are also more likely to get blood clots. To reduce your risk of a blood clot, your doctor may recommend compression stockings or leg exercises you can do in your seat. Also, see CDC’s Blood Clots During Travel page for more tips on how to avoid blood clots during travel.

Choose safe food and drink. Contaminated food or drinks can cause travelers’ diarrhea and other diseases and disrupt your travel. Travelers to low or middle income destinations are especially at risk. Generally, foods served hot are usually safe to eat as well as dry and packaged foods. Bottled, canned, and hot drinks are usually safe to drink. Learn more about how to choose safer  food and drinks  to prevent getting sick.

Pregnant women should not use bismuth subsalicylate, which is in Pepto-Bismol and Kaopectate. Travelers to low or middle income  destinations  are more likely to get sick from food or drinks. Iodine tablets for water purification should not be used since they can harm thyroid development of the fetus.

After Travel

If you traveled and feel sick, particularly if you have a fever, talk to a healthcare provider immediately, and tell them about your travel. Avoid contact with other people while you are sick.

Is it safe to travel to high altitudes while pregnant?

Take care while traveling to high altitudes while pregnant: It isn't always recommended, depending on where you go and how you respond to being there.

At high altitudes, less oxygen is available, which means you'll tire more easily. It also means your baby will get less oxygen, which can negatively affect growth and development.

There isn't much research on the effects of traveling to high altitudes during pregnancy. One study of about 450 women who frequently traveled to and exercised at high altitudes during pregnancy didn't find increased risk of complications, though the study's authors said further research is needed to be sure it's safe.

The Centers for Disease Control and Prevention recommends that pregnant women who are traveling avoid staying at altitudes at or higher than 8,500 feet above sea level for more than a few days, and if possible, avoid sleeping at altitudes higher than 12,000 feet. (Denver is 5,280 feet above sea level and would probably be fine, for example; but Pikes Peak, at more than 14,000 feet above sea level, might not be safe.)

Women respond differently to high altitudes during pregnancy. The symptoms of altitude sickness are often similar to typical pregnancy symptoms – dizziness , shortness of breath , lightheadedness, headaches , and trouble sleeping – so it can be hard to tell if you're suffering from altitude sickness or just going through pregnancy. But if you're getting less oxygen than you're used to and you can feel it, your baby may not be getting as much oxygen, either.

If you feel sick while traveling at higher altitudes than you're used to, go to a lower altitude. And if you still don't feel well after you descend, seek medical care.

The CDC also recommends avoiding strenuous physical activity while at high altitudes during pregnancy (unless you're already trained for exercise at high altitude), since you may experience breathlessness and palpitations. If you're planning a vacation at a higher elevation, plan extra time to acclimate before you jump into any physical activity, and you may need to avoid some activities altogether , like skiing or hiking.

One of the biggest concerns about traveling to higher altitudes during pregnancy is these locations are often remote and far from medical care. Some pregnant women need to be especially careful in these situations. If you have hypertension , preeclampsia , or any other high-risk pregnancy condition, going to high altitudes may make your condition worse – and you could be far from the care you need in case of an emergency. Talk with your healthcare provider before making travel plans.

Research shows that repeated exposure to hypoxia – not getting enough oxygen – during pregnancy increases your risk of preeclampsia and can impact your baby's growth. But if you're just traveling to a high altitude for a few days during your pregnancy and you don't experience noticeable altitude sickness, there's no need to worry.

As for women who live at altitudes higher than 8,500 feet, their bodies have made adjustments over time, including higher levels of red blood cells (more hemoglobin), increased numbers of small blood vessels, and increased proteins in the muscles that store oxygen. These adaptations help people function at higher altitudes.

Babies born to moms living at high elevations tend to be smaller than babies born at lower altitudes. Pregnant women living at high altitudes are at two to three times greater risk of preeclampsia and intrauterine growth restriction . For women whose ancestors lived at high elevations for thousands of years (such as those in Bolivia, Peru, or Tibet), the risk of growth restriction is reduced due to evolutionary adjustments, although their babies are smaller on average than those at lower altitudes.

List of Medications You Can and Can’t Take While Pregnant

• Safe Medications
• Possibly Unsafe Medications
• Unsafe Medications
• If You're Unsure

Certain medications are unsafe during pregnancy because they can cause severe congenital (at birth) disabilities and complications. This includes some medicines for pain and cold symptoms, among others. However, some medications are safe to take while pregnant.

About 9 in 10 pregnant people in the United States use over-the-counter (OTC) medication during their pregnancies, and 7 in 10 take prescription medication.

This article discusses medications that are safe during pregnancy and which are not, and how to know the difference.

The Food and Drug Administration (FDA) determines the safety of drugs. The rating system (called the Pregnancy and Lactation Labeling Rule) classifies medications with a general overview of how safe they are to use during pregnancy, breastfeeding, and for adults of reproductive age.  

List of Safe Medications to Take While Pregnant

Almost all pregnant people in the United States take at least one OTC or prescription medication during their pregnancies. The most common drugs are used for nausea , vomiting, heartburn , infection, and pain. Most commonly used medications are safe for a limited time during pregnancy, but it is always best to ask a healthcare provider first.

If you're pregnant, always check with a healthcare provider before taking any medication.

The following remedies for seasonal allergies are considered safe during pregnancy:

• Chlor-Trimeton (chlorpheniramine)
• Dexchlorpheniramine
• Atarax (hydroxyzine) 

Talk with a healthcare provider before taking the following allergy medications:  

• Benadryl (diphenhydramine)  
• Zyrtec (cetirizine)
• Claritin (loratadine)

Cold and Flu

You’ve likely heard that avoiding certain cold and flu medications is important when pregnant. Talk with your healthcare provider if you are unsure what to take. 

The following medications are considered safe during pregnancy:

• Cough drops 
• Saline nasal drops 
• Saltwater gargle 
• Tylenol (acetaminophen) 
• Mucinex (guaifenesin)
• Vicks VapoRub (menthol cream)

Avoid any long-acting or sustained-released types when choosing a cold or flu medication. 

Constipation

Constipation is a common problem during pregnancy because hormonal changes slow down the gastrointestinal tract. Most healthcare providers recommend increasing your water and fiber intake (fruits, vegetables, beans, whole grains) to help with this.

Medications that can help pregnancy-related constipation include:

• Citrucel (methylcellulose fiber)
• Metamucil (psyllium)
• Colace (docusate) 

COVID-19 Vaccine

All eligible people should receive the COVID-19 vaccine . Pregnant people can get this vaccine in any trimester.  

Heartburn is common during pregnancy and affects between 17% and 45% of pregnant people in the United States. Healthcare providers usually recommend treating it with diet and lifestyle changes, such as avoiding fatty foods, drinking enough water, and sleeping with your head elevated.  

Heartburn medications that are considered safe during pregnancy include:

• Ginger supplements 
• Tums (calcium carbonate)
• Mylanta (calcium carbonate)
• Maalox (aluminum hydroxide) 
• Pepcid AC (famotidine)
• Zantac 360 (famotidine)

Insect Repellent

Insect repellents with DEET (N, N-diethyl-meta-toluamide) provide adequate protection and are approved for use during pregnancy. Less than 10% of the DEET in insect repellents enters your bloodstream and reaches your baby.

Talk with your healthcare provider if you need to use insect repellent regularly during pregnancy.

Nausea and Vomiting

Nausea and vomiting is a common symptom, especially in the first trimester. Medications and supplements that are recommended for pregnancy-related nausea include:

• Ginger capsules or candies
• Unisom (doxylamine)

A healthcare provider may recommend trying a prescription medication if these remedies don't help.

Aches and pains are common during pregnancy. Most healthcare providers recommend Tylenol (acetaminophen) for minor aches and pains such as a headache or low-back pain. 

While nonsteroidal anti-inflammatory drugs (NSAIDs) , such as Advil (ibuprofen) and Aleve (naproxen) , can be taken during pregnancy, there are some slight risks. Speak with a healthcare provider before taking this medication.

Herbs and supplements can treat various conditions but may be unsafe during pregnancy. Ginger is safe for treating heartburn and nausea during pregnancy. For other herbs, talk with a healthcare provider. Some herbs known to be unsafe during pregnancy include:

• Evening primrose oil
• Blue cohosh 
• Raspberry oil 

List of Potentially Unsafe Medications While Pregnant 

Some medications are not safe for every pregnant person but can be used under the guidance of a healthcare provider. Some medicines are safe in one trimester but not others.

Sudafed (pseudoephedrine) carries a small risk of congenital disabilities in the abdominal wall in the first three months of pregnancy. Avoid this medication during your first trimester. Talk with your healthcare provider if you’d like to try it in your second or third trimester.  

If you continue to experience constipation despite diet and lifestyle changes, ask a healthcare provider about Miralax (polyethylene glycol 3350) . This medication is considered safe for occasional use during pregnancy.

Depression and Anxiety

Anxiety and depression medications cross the placenta, meaning they reach your baby while you are pregnant. They are also present in breast milk. Many selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants can be safely taken during pregnancy under a healthcare provider's guidance. These may include:

• Celexa (citalopram) 
• Zoloft (sertraline) 
• Lexapro (escitalopram) 
• Amitriptyline
• Nortriptyline 

Benzodiazepines are used to treat anxiety and insomnia. Studies show that they do not pose a serious risk to a fetus. Benzodiazepines that may be safe during pregnancy when taken in small doses include Valium (diazepam) and Xanax (alprazolam).

About 500,000 pregnant people in the United States experience psychiatric illness each year. It’s estimated that 10% to 16% of pregnant people meet the criteria for depression , and up to 70% have some symptoms of depression.  

List of Unsafe Medications to Not Take While Pregnant

While uncommon, certain medications have been linked to an increased risk of congenital disabilities, pregnancy loss, premature birth, and infant death. 

Nyquil is not recommended for pregnant or breastfeeding people because of its high alcohol content. 

Paxil (paroxetine) and Sinequan (doxepin) are not considered safe during pregnancy and have been linked to congenital disabilities.  It is possible for babies to experience withdrawal symptoms after being exposed to the following medications:

• Xanax (alprazolam)
• Librium (chlordiazepoxide)
• Valium (diazepam)

In most cases, opioid medications are not recommended for pregnant or breastfeeding people. These medications can significantly impact your baby's health and cause withdrawal symptoms after birth. However, medications might be needed at certain times, such as a serious injury or surgery.  

Common opioid medications include:

• Hydromorphone

Other prescription medications to treat chronic conditions may be unsafe during pregnancy. Never stop taking prescription medication without talking with a healthcare provider first. 

Some medications can be safely used during pregnancy but not breastfeeding, or vice versa. For example, it may be safe to take benzodiazepines for anxiety during pregnancy. However, this drug class can cause sedation and poor infant feeding when nursing.

Pregnancy-Safe Medications: If You’re Ever Unsure 

If you ever wonder if your medication is safe, always call a healthcare provider or pharmacist. They can review your overall health and individual risks to help you make the best decision for you and your baby. 

Knowing which medications are safe during pregnancy and breastfeeding is a challenge. Many commonly used drugs can be safely taken when you are pregnant. Always talk with a healthcare provider before starting a new medication or supplement. Some medicines can interact with each other or raise the risk of congenital disabilities and other serious pregnancy problems.

Travel sickness is caused by a mismatch of signals to the brain between your eyes and the balance mechanism in your inner ear. The brain is confused and reacts with symptoms of travel sickness.

Scientists still don't have the answer to this one, though it seems that women and migraine sufferers are more likely to develop motion sickness. There is a suggestion that it runs in families and that our bodies can adapt and become less susceptible. In particular, seasick sailors will often acclimatise after 3 or 4 days at sea.

The main symptoms of travel sickness are pale, cold, sweaty skin, dizziness, and vomiting. The sufferer will tend to become quiet and withdrawn. If it becomes very severe, especially with a prolonged sea sickness, you can also suffer from headache, lethargy, lack of concentration, and repeated vomiting leading to dehydration.

You can try several other things as well as, or instead of, medicines - they include:

• Sitting in a calmer part of the car, boat, or plane such as the front seat, centre of the boat, or by the wing on a plane.
• Focusing your eyes on the distance or the route ahead by steering the boat or driving (only if not severely affected).
• Stay in fresh air either outside or with an open window.
• Sleeping or resting with your eyes closed.
• Don't focus on close objects such as looking at screens or reading.
• Do not eat heavy spicy meals or take alcohol, and avoid cooking smells.
• Break up the journey if possible.
• You can buy acupressure bands and anti-motion sickness glasses which some people find helpful.

Dr Fox supplies hyoscine, promethazine, and cinnarizine to treat travel sickness. Hyoscine can be used as a patch ( Scopoderm ) or tablets ( Kwells ). Promethazine ( Avomine ) and cinnarizine ( Stugeron ) are tablets. All treatments are most effective if started before you travel and feel unwell but may help to improve symptoms if you are already feeling sick.

The patch is stuck on the skin behind your ear and lasts for 3 days. After this it should be removed and a new patch placed behind the other ear if required. More details on the Scopoderm page and in the Scopoderm patient leaflet . It is important to remove one patch before starting another to prevent overdose and also to wash your hands after touching the patch. Avoid touching your eyes after handling the patch.

Dr Fox offers three different tablets and patches. The table below shows the major differences. It depends on the length of your intended journey. Some people will get on better with one tablet than another, or prefer to use a patch.

If over 60 you should NOT take Kwells (hyoscine) or use Scopoderm patches (hyoscine) without discussing with your regular doctor first. You can take the antihistamine tablets, either Avomine (promethazine) or Stugeron (cinnarizine). If you are also taking other medicines or have certain medical conditions you may not be able to take these either. Checks are carried out during the online medical consultation .

Anti-travel sickness medications can interact with some other tablets and medicines. Checks are carried out during the online medical consultation , but you should also read the patient information leaflet and if in doubt check with your usual doctor.

Alcohol should not be taken with any of the travel sickness medications.

Please discuss with your regular doctor if you suffer from severe travel sickness and are pregnant or breastfeeding. The medications supplied by Dr Fox are not recommended to be taken when pregnant or breastfeeding. However in cases of extreme morning sickness - Hyperemesis gravidarum, doctors do occasionally prescribe similar medications. This is a specialist area and Dr Fox does not prescribe in pregnancy or to breastfeeding mums.

Further information

• Medicines in pregnancy - Hyoscine (Scopoderm, Kwells)
• Medicines in pregnancy - Promethazine (Avomine)

All travel sickness medications can cause drowsiness and so you should not take them and drive, until you are sure that your body has adjusted to them, usually after a few days. Often the driver of a vehicle feels less travel sick as they are concentrating on the road ahead and there is less mismatch of movement signals to the brain. Do not drive if you are feeling very travel sick.

Some people with sensitive skin do develop itching and soreness at the site of the patch. If this happens it will affect the absorption so the patch should be removed and an alternative travel sickness medication used instead.

If you have a known plaster/patch allergy, it would be preferable to choose an alternative anti-sickness method.

There are a lot of potential side effects from these medications but in reality most people do not have many problems and the medication enables them to undertake journeys which would otherwise be very miserable. If you suffer badly from travel sickness, and have already tried the non medical methods, then it would definitely be worth looking at the product information pages ( Scopoderm , Kwells , Avomine , Stugeron ) to see if there is a suitable option for you to try.

• There is no lactose in Kwells.
• Avomine contains lactose.
• Stugeron contains lactose and sucrose.

Nausea medicine

Peer reviewed by Dr Colin Tidy, MRCGP Last updated by Dr Toni Hazell Last updated 14 Jun 2023

Meets Patient’s editorial guidelines

In this series: Nausea and vomiting Dehydration

Various medicines are available to treat nausea . They work in different ways to one another. These medicines are not usually started until your doctor is sure what has caused your nausea. This is because knowing the cause helps your doctor to choose the right medicine for you. If they are required then any medicine usually only needs to be taken for a few days. Most people are able to take these medicines.

In this article :

Types of nausea medicine, when is nausea medicine prescribed, which medicine is usually prescribed for nausea, side-effects of nausea medicine.

Continue reading below

The medicines for nausea used are sometimes called antiemetics. Some of these medicines work on the gut and speed up how quickly food moves through it. Other medicines work on the brain and block signals to the vomiting centre. Listed below are some of the more commonly prescribed medicines:

Cinnarizine , cyclizine , promethazine - these medicines belong to a group of medicines called antihistamines . The exact way that they work is not fully understood. It is thought that antihistamines block histamine 1 (H1) receptors in the area of the brain which creates nausea in response to chemicals in the body. They are thought to work well for nausea caused by a number of conditions including ear problems and motion (travel) sickness.

Hyoscine - this medicine works by blocking a chemical in the brain called acetylcholine. It is a type of medicine called an antimuscarinic (or anticholinergic). It works well for nausea caused by ear problems and motion sickness.

Chlorpromazine , haloperidol , perphenazine, prochlorperazine , levomepromazine - these medicines work by blocking a chemical in the brain called dopamine. They are useful for nausea that is caused by some cancers, radiation and opiate medicines such as morphine and codeine. Prochlorperazine (or brand name Stemetil®) is one of the most used medicines for nausea. It works for many common causes of nausea, including vertigo, ear problems and sickness in pregnancy.

Metoclopramide - this medicine works directly on your gut. It eases the feelings of sickness by helping to empty the stomach and speed up how quickly food moves through the gut. It is often used for people with sickness due to gut problems or migraine. It is not usually used for more than a few days.

Domperidone - this medicine works on the CTZ. (CTZ stands for chemoreceptor trigger zone.) It also speeds up the emptying of the gut. It is not usually used for more than a few days. The use of domperidone is strictly regulated following a 2014 warning about the risk of cardiac (to do with the heart) side-effects. It is no longer available over the counter and should only be used at the lowest effective dose for the shortest possible time.

Dexamethasone - this is a steroid medicine. It is a man-made version of a natural hormone produced by your own body. Dexamethasone has a wide range of actions on many parts of the body. The reason why it reduces nausea is not clear.

Granisetron , ondansetron , and palonosetron - these medicines work by blocking a chemical called serotonin (5-HT) in the gut, and the brain. Serotonin (5-HT) has an action in the gut and the brain to cause nausea. These medicines are useful for controlling nausea and vomiting caused by chemotherapy.

Aprepitant and fosaprepitant - these are newer medicines and work by blocking a chemical that acts on neurokinin receptors in the body to cause nausea. They are sometimes called neurokinin-1 receptor antagonists. They are usually given to people on a certain type of chemotherapy.

Nabilone - it is still not clear how this medicine works to control nausea. It is normally prescribed for people who are having chemotherapy.

Medicines for nausea are usually only prescribed once your doctor is sure what is causing your feeling of sickness (nausea). This is because, in a lot of cases, if you treat the condition causing your nausea, it will go away. For example, if your nausea is caused by taking too much of a particular medicine, your doctor will reduce the dose and your nausea will often go away.

If the cause of your nausea is not known, your doctor can still prescribe a medicine for you but it is much better to know what the cause is so the right medicine can be chosen.

The choice of medicine depends on various factors, including:

What is causing your feeling of sickness (nausea).

Whether you have any other medical conditions.

Whether you are pregnant.

Possible side-effects of the medicines.

It is not possible to list all the conditions that can cause nausea and which treatments are usually prescribed. However, some examples include:

Motion (travel) sickness : hyoscine is the most effective medicine for motion sickness. Promethazine, cyclizine, or cinnarizine also work well. See the separate leaflet called Motion Sickness (Travel Sickness) for more detail .

Pregnancy : if you are pregnant, your doctor will usually prefer not to treat nausea and being sick (vomiting) with medicines unless the symptoms are severe. However, if it is decided that you need treatment, generally promethazine, prochlorperazine, or metoclopramide may be prescribed. This is because they are not thought to harm the unborn baby. See the separate leaflet called Morning Sickness in Pregnancy for more detail .

Migraine : both metoclopramide and domperidone work well for nausea caused by a migraine. See the separate leaflet called Migraine Medication, Treatment and Prevention for more detail .

Chemotherapy : it is not unusual to take a combination of different medicines to control nausea and vomiting if you have chemotherapy. Some chemotherapy medicines are more likely than others to cause nausea and vomiting. If you have chemotherapy that has a low risk of nausea, your doctor will usually prescribe metoclopramide or domperidone. If you have chemotherapy that has a high risk of nausea, three medicines that work in a different way to each other may be prescribed - for example, ondansetron, dexamethasone and aprepitant. See the separate leaflet called Chemotherapy for more detail.

It is not possible to list all the possible side-effects of each of these medicines in this leaflet. However, as with all medicines, there are a number of side-effects that have been reported. To see the side-effects specific to your medicine, see the information leaflet that came with your medicine.

Common side-effects may include:

Constipation .

Headaches .

Drowsiness or tiredness.

Trouble with sleeping ( insomnia ).

Indigestion .

However, the side-effects are different with each different medicine. Most side-effects are not serious and each person may react differently to these medicines. Usually most people do not get the side-effects listed; however, they can happen to some people.

Travelling while pregnant

Find useful information and considerations to help you prepare for safe and healthy travels outside Canada while pregnant.

With careful preparation, travelling while pregnant can be safe. The decision to travel should be made in consultation with your health care professional, based on your personal health circumstances.

On this page

Before you go, while you're away, if you need help.

Medical practices, health standards and infection control measures vary from country to country. You may not have access to the same level of care, procedures, treatments and medications as you would in Canada.

You could also be at increased risk of getting an infection and/or developing severe complications from certain infections, which could also affect the fetus.

Before leaving Canada:

• consult a health care professional or visit a travel health clinic at least 6 weeks before travelling to get personalized health advice and recommendations
• check our Travel Advice and Advisories for country-specific information, including about possible health risks
• know how to seek medical assistance outside of Canada
• review the policy and the coverage it provides
• most policies do not automatically cover pregnancy-related conditions or hospital care for premature infants
• ask your insurance provider about coverage for medical care during pregnancy, giving birth and intensive care for you and your fetus or newborn
• carry a copy of your prenatal records
• talk to your health care professional about any additional items you may want to bring that are specific to your health needs

Local laws and medical services relating to pregnancy can differ from Canada. Learn the local laws, and how these may apply to you before you travel.

Pre-travel vaccines and medications

Many vaccines can be safely given during pregnancy. Due to a higher risk of more severe outcomes for you and your fetus, some vaccines are recommended specifically during pregnancy, such as tetanus-diphtheria-pertussis (DTaP) and influenza.

Don’t take medications you may still have from prior trips. Tell the health care professional about your pregnancy, or intended pregnancy, before filling any prescriptions. The decision to get any pre-travel vaccinations or medications should be discussed with your health care professional.

The decision can depend on:

• your purpose of travel (e.g., tourism, visiting friends and relatives)
• your planned destination(s)
• the length of your trip
• your risk of getting a disease
• how severe the effect of a disease would be to you and/or your fetus
• your planned activities
• any underlying medical issues and/or pregnancy-related complications

Malaria could cause major health problems for a mother and her unborn baby. A pregnant woman may want to consider avoiding travel to areas where malaria transmission occurs.

Description of malaria risk by country and preventative measures.

If you can’t avoid travelling to an area where malaria is present:

• some medications to prevent or treat malaria may not be safe during pregnancy
• take extra care to protect yourself from mosquito bites

Zika virus infection during pregnancy can pose significant risks to your fetus even if you don’t develop symptoms. While pregnant, you may want to consider avoiding travelling to a country or areas with risk of Zika virus.

Latest travel health advice on Zika virus.

If you choose to travel, take precautions to avoid infection with Zika virus:

• prevent mosquito bites at all times
• protect yourself from contact with semen, vaginal fluid and blood
• always use condoms correctly or avoid sexual contact while in countries or areas with risk of Zika virus

Learn more about Zika virus and pregnancy:

• Zika virus: Pregnant or planning a pregnancy
• Zika virus: Advice for travellers
• Pregnancy and travel (tropical medicine and travel)

Monitor your health and be prepared

Emergencies can happen at any time. Know where the nearest hospital or medical centre is while you are travelling and confirm they will accept your medical insurance.

Seek medical attention immediately if you develop any of the following symptoms while travelling:

• persistent vomiting and/or diarrhea
• dehydration
• vaginal bleeding
• passing tissue or clots
• abdominal pain, cramps or contractions
• your water breaks
• excessive swelling of face, hands or legs
• excessive leg pain
• severe headaches
• visual problems

If you develop these symptoms after your return to Canada, you should see a health care professional immediately and tell them about your recent trip.

Transportation

Always wear a seatbelt when travelling by plane or car. When using a diagonal shoulder strap with a lap belt, the straps should be placed carefully above and below your abdomen. If only a lap belt is available, fasten it at the pelvic area, below your abdomen.

If you have any medical or pregnancy-related complications, discuss with your health care professional whether air travel is safe for you.

Most airlines restrict travel in late pregnancy or may require a written confirmation from a physician. Check this with the airline before booking your flight.

During long flights, you may be at higher risk of developing blood clots, known as deep vein thrombosis (DVT). The risk of deep vein thrombosis can be reduced by:

• getting up and walking around occasionally
• exercising and stretching your legs while seated
• selecting an aisle seat when possible
• wearing comfortable shoes and loose clothing

Your health care professional may recommend additional ways to reduce your risk such as wearing compression stockings.

Always stay well hydrated while travelling.

Land travel

The risk of deep vein thrombosis can be reduced by:

• stopping the vehicle to walk around every couple of hours

Motion sickness

Certain medications used to treat nausea and vomiting during pregnancy may also be effective in relieving motion sickness.

If you think you might experience motion sickness during your trip, speak to your health care professional about the use of these medications.

Environmental and recreational risks

Some activities may not be recommended or may require additional precautions. Discuss your travel plans, including any planned or potential recreational activities with a health care professional.

High altitude

You should avoid travelling to an altitude above 3,658 metres (12,000 feet).

However, if you have a high-risk pregnancy and/or are in the late stages of pregnancy, the highest altitude should be 2,500 metres (8,200 feet).

If you have pregnancy-related complications, you should avoid unnecessary high-altitude exposure.

Keep in mind that most high-altitude destinations are far from medical care services.

Personal protective measures

Food-borne and water-borne diseases.

Eat and drink safely while travelling while travelling. Many food-borne and water-borne illnesses can be more severe during pregnancy and pose a risk to the fetus.

This can include:

• toxoplasmosis
• listeriosis
• hepatitis A and E

To help avoid food-borne and water-borne diseases:

• before eating or preparing food
• after using the bathroom or changing diapers
• after contact with animals or sick people
• before and after touching raw meat, poultry, fish and seafood
• if you’re at a destination that lacks proper sanitation and/or access to clean drinking water, only drink water if it has been boiled or disinfected or if it’s in a commercially sealed bottle
• use ice made only from purified or disinfected water
• this could cause the fetus or newborn to develop thyroid problems
• unpasteurized dairy products, such as raw milk and raw milk soft cheeses
• unpasteurized juice and cider
• raw or undercooked eggs, meat or fish, including shellfish
• raw sprouts
• non-dried deli meats, including bologna, roast beef and turkey breast
• don’t use bismuth subsalicylate (Pepto-Bismol®)
• Information on travellers’ diarrhea

Illnesses acquired from insect and other animals

Protect yourself from insect bites:

• wear light-coloured, loose clothes made of tightly woven materials such as nylon or polyester
• prevent mosquitoes from entering your living area with screening and/or closed, well-sealed doors and windows
• use insecticide-treated bed nets if mosquitoes can’t be prevented from entering your living area
• information on insect bite and pest prevention

Some infections, such as rabies and influenza, can be shared between humans and animals. You should avoid contact with animals including dogs, livestock (pigs, cows), monkeys, snakes, rodents, birds, and bats.

Is it safe to travel to high altitudes when pregnant? Yes, to a point

• Obstetricians recommend women travel not much higher than 8,000 feet above sea level while pregnant.
• High altitudes reduce the amount of oxygen in the blood which can cause you and your fetus to develop a condition called hypoxia.
• This article was medically reviewed by Olivia P. Myrick , MD, who is a clinical assistant professor with the Department of Obstetrics and Gynecology at  NYU Langone .
• Visit Insider's homepage for more stories .

Planning a trip to the mountains during your pregnancy? Whether it's a day hike or overnight stay, you should check with your doctor first.

It is usually safe to travel up to 8,000 feet, but you should get acclimated first

Traveling to higher elevations exposes your body — pregnant or not — to lower air pressure and leads to lower oxygen levels in the blood. As a result, your tissues can become deprived of oxygen, a condition known as hypoxia. 

When you're pregnant, your body should typically acclimate to the lower oxygen levels, thereby ensuring your baby continues to receive adequate oxygen. So, for women who are healthy and have a complication-free pregnancy, traveling up to 8,000 feet above sea level is generally considered safe says Annie Porter , MD, an obstetrician in the Maternal Fetal Medicine Fellowship Program at University of Colorado Anschutz Medical Campus.

"We do recommend a period of acclimating though," Porter tells Insider. For example, if you are planning a trip to an elevation of 7,500 feet, try to start by spending a day or two at an elevation of 5,000 feet to acclimate.

However, if you're planning a strenuous hike at altitude, proceed with caution. The CDC recommends that pregnant women avoid vigorous activity at high altitudes unless properly trained and accustomed to the environment. 

This is especially important because the symptoms of acute mountain sickness — including insomnia, headache, and nausea — are often mistaken for normal, pregnancy-related discomfort. If you have these symptoms at altitude, return to a lower altitude and consult your doctor. 

At altitudes above 8,000 feet, proceed with caution

If you're traveling to high altitudes — that is, between 8,000 feet and 12,000 feet — that can be more problematic. In fact, according to the World Health Organization , you should not sleep at elevations above 9,800 feet at any point during pregnancy.

Given the limited data available, it is unclear exactly how high altitudes will affect your pregnancy. One of the few studies that exist was a relatively small study , published in 2016 in Wilderness and Environmental Medicine , which showed that among 298 surveyed women, those who traveled to high altitudes during pregnancy were slightly more likely to go into early labor. 

But these women who were briefly exposed to higher altitudes did not have a higher rate of other complications, such as miscarriage, preeclampsia, or bleeding during pregnancy. Moreover, while their results were statistically significant, the researchers could not conclude that early labor was caused by the women's time at high altitudes, they merely reported a link. 

Most of the evidence available is for women who live at high altitudes (between 8,000 feet to 12,000 feet), and the evidence suggests that these women have a higher risk of developing preeclampsia and giving birth to smaller babies than women who live at low altitudes. For women who just visit, that exposure to high altitude probably isn't long enough to have an effect on their pregnancy overall, says Porter.

If you have had hypertension or preeclampsia, take extra caution

High-risk pregnancies — where the woman, baby, or both have an increased risk of developing complications — are more likely to have problems when traveling to high altitudes. That's because you and the baby may not be able to fully acclimate to the lower oxygen levels. 

Common reasons a pregnancy may be high risk is if the woman had hypertension before pregnancy or developed preeclampsia during pregnancy. Also, pregnant women who smoke are considered to have a high-risk pregnancy and could have more problems at higher altitudes. Pregnant women with any preexisting medical conditions should consult their physician before traveling , no matter where the destination may be. And if you're planning to fly anywhere check out our article on how late in pregnancy you can fly .

But it's not just the high altitude that can be dangerous during pregnancy. Traveling for hiking or backpacking trips usually means a journey to a very remote area. "If you're going on a hike to 10,000 feet, what I'm worried about is you're going to be far away from medical care," says Porter.

Porter recommends that you check with your obstetrician before making plans to travel to high altitudes or rural locations during pregnancy.

Advice for Pregnant Travellers

Disease risks, maternity notes and medical care, travel insurance, vaccinations, malaria prevention.

Pregnancy creates an altered state of health which requires practical consideration before travel. In the first instance travel plans should be discussed with your GP, practice nurse, midwife or obstetrician, ideally before booking and well in advance of your intended departure date.

Fluctuating hormone levels and the psychological impact of pregnancy, as regards changing routines and responsibilities, may adversely affect your capacity to cope with the stressful nature of travel. It is therefore worth considering if you will have access to sufficient emotional and physical support during travel.

Many diseases have more severe consequences in pregnancy, with significant risk to both mother and unborn baby. For example, malaria in pregnancy is harmful to both you and your unborn baby with an increased risk of severe illness or death for both. Consequently, where possible, you should avoid all non-essential travel to tropical destinations during pregnancy, in particular those with a risk of diseases such as malaria , zika virus or yellow fever .

The association between infection with zika virus and birth defects means that non-essential travel to areas with ongoing high risk of zika virus transmission should be postponed by women who are pregnant or planning pregnancy. For further information see our zika virus  page.

Take a copy of your hand held maternity notes in case you need medical care during travel; include information about any pre-existing medical conditions and your blood group.

Carefully consider your intended destinations prior to booking, find out about:

• availability and standard of medical care
• existing health risks in the destination countries
• any other travel warnings.

The Foreign, Commonwealth and Development Office (FCDO) website provides advice on the availability of medical treatment and facilities alongside any travel warnings on an individual country basis.

It is essential that all your early pregnancy examinations are carried out prior to travel in order to rule out potential complications. If travelling after 28 weeks of pregnancy, it is important to ensure that available medical facilities at the destination are suitable to manage complications of pregnancy such as pre-eclampsia and caesarean section.

Be aware that blood supplies may not be safe in some destinations; this can increase the risks of blood borne infections such as hepatitis B , C and HIV .

Misunderstandings due to language barriers or cultural problems could make communication and therefore diagnosis and treatment of any illness more difficult than it would be at home.

Ensure that your travel insurance policy covers both you and your unborn child, and if delivery should occur during travel, that your newborn is insured.

Failure to notify your travel insurance provider that you are pregnant is likely to invalidate your insurance policy.

Additionally, it should be remembered that insurance policies are only as good as the medical facilities available.

Please see our travel insurance page for further information.

Air travel is generally considered safe in uncomplicated pregnancy. However, it is important to discuss your fitness to fly with your GP, practice nurse, midwife or obstetrician before departure.

Be aware that policies vary between each airline but generally:

• Most commercial airlines accept pregnant travellers up to 36 weeks if single pregnancy or up to 32 weeks if a multiple pregnancy. This is because labour is more likely after 37 weeks, or around 32 weeks if carrying an uncomplicated twin pregnancy.
• Some airlines require written documentation from your practice nurse, midwife or obstetrician. This is to confirm you are in good health, that your pregnancy is uncomplicated and your due date.
• Flying during the first 12 weeks of pregnancy may be considered risky as miscarriage is more common during this early stage. Additionally, at this stage pregnant travellers may be suffering from pregnancy induced nausea and fatigue which could make travelling uncomfortable.
• You may be at greater risk of deep vein thrombosis (DVT) during pregnancy and the postpartum period; please refer to our Deep Vein Thrombosis page for further information.

Pregnancy does not prevent you from receiving vaccines that can protect the health of you and your unborn baby.

A general rule is that most recommended vaccines can be used if the risk of infection is substantial and if there are serious consequences of infection. However, a careful risk versus benefit analysis is needed for every individual, and the decision on whether to vaccinate should be made in conjunction with an appropriately qualified health care professional.

Inactivated Vaccines in Pregnancy

Inactivated vaccines cannot replicate which means they cannot cause disease in either the mother or her unborn baby. Most inactivated vaccines can be used if the risk of disease is considered high.

Live Vaccines in Pregnancy

The risk of the disease versus the benefit of administering any live vaccine during pregnancy requires expert consideration and expert advice should be sought. This is due to a theoretical concern that vaccinating pregnant women with live vaccines, such as: measles, mumps, rubella, chicken pox (varicella) and yellow fever, could potentially infect the unborn baby. Consequently, live vaccines are usually avoided during pregnancy. However, the use of live vaccines in pregnancy may be appropriate if travel is unavoidable and the risk of the disease is high.

Malaria in pregnancy is associated with miscarriage, premature delivery, low birth weight, severe illness or death, affecting both the mother and unborn baby. Consequently, you should avoid all non-essential travel to known malaria risk areas during your pregnancy.

If travel to a malaria area is unavoidable then it is important that you seek expert advice. In the first instance contact your GP for advice, however, be aware that they may refer you to a specialist travel medicine service.

Mosquito bite avoidance is essential in the prevention of malaria. Pregnant women are more attractive to mosquitoes and should therefore be particularly careful to avoid mosquito bites.

For further information please see our mosquito bite avoidance page.

Malaria Medication in Pregnancy

If antimalarial tablets are recommended then you should seek expert advice about which malaria tablets are safest for you to take.

The choice of malaria tablets will largely be determined by your destination, stage of pregnancy and any other pre-existing medical conditions you may have.

Malaria tablets should always be used in combination with mosquito bite avoidance .

• Motion sickness is also known as travel sickness, car sickness or sea sickness.
• If you have motion sickness, you are likely to have nausea and may vomit and feel clammy.
• You can help prevent motion sickness by looking outside of the vehicle or focusing on the horizon.
• Symptoms usually end once the motion stops.
• You can try travel sickness treatments to help prevent motion sickness.

What is motion sickness?

Motion sickness is feeling unwell when moving on any type of transport. It is also known as ‘travel sickness’, 'car sickness' or 'sea sickness'. It is a normal response to certain types of movement.

There are a few ways to prevent and manage motion sickness.

What are the symptoms of motion sickness?

Nausea is the main symptom of motion sickness. But you might also experience other symptoms, including:

• vomiting or retching
• cold sweating
• lack of appetite
• dry mouth or excess saliva
• increased sensitivity to smell

If you are prone to motion sickness, you may quickly feel sick if you read a book or look at your phone when in a moving vehicle.

You might feel better after vomiting, and symptoms will generally improve once you stop moving. But you can also feel the after-effects of motion sickness for a few hours or a few days before fully recovering.

What causes motion sickness?

Motion sickness is thought to be caused by your senses being confused when what you see is different to the signals felt by your inner ear balance system .

If you are feeling anxious about travel, this can make motion sickness worse.

You can get motion sick when:

• travelling by car, bus, boat, train or aeroplane
• on amusement park rides
• playing virtual reality video games or simulations

Motion sickness is a common problem. It is most frequent in children aged between 2 and 12 years. If other family members get motion sickness, it is more likely that you will too.

If you already have a condition that causes nausea, such as morning sickness or migraines , you may be more likely to experience motion sickness.

How is motion sickness diagnosed?

You don’t need to see a doctor or get any tests for a diagnosis of motion sickness. There is a pattern of feeling unwell during travel or movement, so you will probably know if you have it.

If you often feel dizzy or nauseous at other times too, discuss this with your doctor.

ASK YOUR DOCTOR — Preparing for an appointment? Use the Question Builder for general tips on what to ask your GP or specialist.

How is motion sickness treated and prevented?

Practical tips.

Here are some tips for preventing motion sickness:

• Look out of the window, and focus on the horizon instead of looking at a book or a screen.
• Try to sit or lie still and rest your head on a pillow or headrest.
• Sit close to the front of a car, bus or train.
• If flying, sit still and close your eyes during take-off and landing.
• Listen to music and breathe mindfully .
• Open the window or air vent for fresh air.
• Eat lightly before and during the trip and avoid alcohol. Sip water instead.

Pressure bands worn on your wrists may help prevent motion sickness in some people.

If you are travelling by sea, after a few days of exposure to the motion you will likely adapt and get used to it.

You can try taking travel sickness medicines to prevent motion sickness. These may include:

• antihistamines
• antiemetics (medications to prevent and treat nausea and vomiting)

There might be side effects, such as drowsiness. Ask your pharmacist or doctor for advice on what to take. Getting advice is especially important:

• for children
• if you are taking other medicines
• if you are pregnant

If you are using a travel sickness medicine, you should take it about half an hour before travel. If you have motion sickness and you already feel nauseous, it is probably too late to take a medicine. Eating a few plain crackers or having a clear, fizzy drink may help.

If you or your child regularly suffer from motion sickness, make sure you have a container, plastic bags and wipes handy. Take a break for some fresh air when needed.

Resources and support

Ask your doctor or pharmacist how to prevent and treat motion sickness.
