OTC Medication Use In Pregnancy: Wise or Worrisome?

Medically reviewed on Jun 21, 2016 by L. Anderson, PharmD

How Should I Approach Medication Use in Pregnancy?

There will be times in your pregnancy when you simply don't feel well - you may have a headache, cold, allergy or backache - and you wonder if it's safe to take the same medications you took before you became pregnant. It is important to talk to your doctor before you take any medication - prescription, over-the-counter, herbal or vitamin supplement, during pregnancy.

Women who are just starting to plan a pregnancy should discuss the need for medications with their doctor beforehand. For women with chronic conditions such as asthma, epilepsy or heart conditions, medication may need to be continued throughout pregnancy. And it's important to remember that in every pregnancy there is a 3-5% chance of having a baby with a birth defect, even if you take no medications.

Can I Take My Regular Medications in Pregnancy?

Ask your doctor as soon as possible about your regular medications before you make any changes. Many woman can and should continue their medications for chronic conditions during pregnancy, but each decision is made on a case-by-case basis. Your doctor can weigh the risk and benefits of continuing your medicine in pregnancy.

For some conditions, such as asthma or epilepsy, the risk of NOT taking the medicine might be more harmful to you or your baby than the risk of continuing the medication.

How Common is Medication Use During Pregnancy?

Statistics show that medication use during pregnancy is surprisingly common. Prescription drug use in the first trimester has increased by over 60 percent in the last 30 years. In addition, use of four or more medications in the first trimester tripled.

This raises concern as some medications used during organogenesis (the time period of organ development in the first 12 weeks) can be associated with developmental abnormalities. Although animal studies can provide some information about drug toxicity in pregnancy, these results cannot be safely extrapolated to humans. About 10 percent of birth defects result from drug exposure in pregnancy.

How Does the FDA Categorize Pregnancy Risks Now?

In the past, FDA had established prescription drug pregnancy risk categories as A, B, C, D or X. However, in 2015 the FDA decided to replace these risk categories on prescription drugs with new information to make them more meaningful to both patients and healthcare providers, allowing better counseling and informed decision making. The new sections include
  • Pregnancy (includes Labor and Delivery)
  • Lactation (includes Nursing Mothers)
  • Females and Males of Reproductive Potential

Prescription drugs submitted for approval after June 30 2015, will use the new format immediately, while labeling for prescription drugs approved on or after June 30, 2001, will be phased in gradually. Labeling for OTC medicines will not change; OTC drug products are not affected by the new FDA pregnancy labeling.

Aren't All Drugs Tested for Safety in Pregnancy?

No. The safety of many drugs in pregnancy are not known because pregnant women are excluded from drug research studies due to safety concerns for the unborn baby.

However, drug companies may be required to set up pregnancy registries that collect information about women who have used certain medications during pregnancy. Using this data, a research study can outline the benefit-to-risk of using the drug in pregnancy. Health care professionals can look at this published literature to better determine a drug's safety in pregnancy, and compendiums can be published with the available data.

Is Tylenol Safe?

Acetaminophen (Tylenol) is a common over-the-counter (OTC) pain, headache and fever treatment routinely used in pregnancy. Studies have shown acetaminophen to be safe in pregnancy at recommended doses for short-term use. Most health care providers consider acetaminophen the pain reliever of choice during pregnancy. An increased risk of birth defects, miscarriage, or still birth has not been seen following use of normal acetaminophen doses; however, overdoses in the mother may lead to fetal death or spontaneous abortion.

Follow dosing directions closely, as high doses of acetaminophen can be toxic to the liver or kidney, both in you and your baby. Acetaminophen is found in many other medication, both prescription and OTC, so be sure not to exceed 3,000 to 4,000 mg of acetaminophen per day from all products.

Beware with Aspirin Use

Aspirin should be avoided in pregnancy unless specifically recommended by your doctor. It does cross the placenta. Aspirin can interfere with blood clotting and can contribute to bleeding for both the mother and the baby, especially later in pregnancy or during birth. Aspirin used in the 3rd trimester can also lead to the premature closure of a vessel in a baby's heart (ductus arteriosus) that may lead to elevated lung pressure in the newborn.

In some pregnant women, low-dose aspirin may be used for certain medical conditions, but only under the direct care a physician. If a medication for minor pain, headache or fever is required, acetaminophen is usually a safer option.

My Back Aches: NSAID Safety in Pregnancy

Nonsteroidal antiinflammatory drugs (NSAIDs) like ibuprofen (Advil, Motrin) are commonly found in OTC medications. Ask your doctor about NSAID use in pregnancy. Some birth defects as well as an elevated risk for miscarriage have been reported with NSAIDs; more study is required to definitely link these outcomes, however, caution is advised. Infertility due to frequent use of NSAIDs has also been reported, but may be reversible if the NSAID is stopped.

NSAIDs should NOT be used in the third trimester of pregnancy unless specifically prescribed by your doctor. Like aspirin, NSAIDs like ibuprofen may interfere with the closure of the ductus arteriosus in the baby's heart. Acetaminophen is usually the pain and fever reliever of choice in pregnancy.

Drug Use in Pregnancy: Cough Suppressants

Pregnant women may be more prone to colds and flu because their immune system to fight off illnesses is slightly lowered in pregnancy.

The available human data have not found an association between dextromethorphan (Delsym, Vicks Formula 44) and an increased risk of birth defects in humans, and it's use has been noted as compatible with both pregnancy and breastfeeding by Briggs. However, dextromethorphan should only be given if the benefit to the mother justifies the potential risk to the fetus as determined by your doctor. Cough suppressants containing ethanol (alcohol) should be avoided.

Cough lozenges are safe, or a soothing drink of honey, lemon and warm water can be a natural help for a cough.

The Stuffy Nose and Pregnancy: What to Do?

Pseudoephedrine and phenylephrine (Sudafed, Sudafed PE) are OTC medicines used to relieve nasal congestion caused by colds and hay fever. Decongestants can cause blood vessel narrowing and elevate blood pressure. It is best to avoid decongestants in pregnancy, some case studies as reported by Briggs suggest minor malformations may occur with 1st trimester use of pseudoephedrine. Decongestants should only be used in pregnancy if benefit outweighs risk.

Alternatives to oral decongestants, like nasal saline solutions (Ayr) or a decongestant spray (Neo-Synephrine) may be safer options, but limit use of decongestant sprays to no more than 3 days in a row to prevent rebound congestion.

Caffeine: Can I Still Have My Latte?

Caffeine has not been linked to birth defects, but most health experts agree that low to moderate caffeine consumption in pregnancy is key, meaning roughly 200 to 300 milligrams (mg) of caffeine per day (1-3 eight oz. cups of coffee). Most coffees purchased today exceed an eight ounce cup. It's important to remember that caffeine will also cross the placenta and stimulate a baby the same way it does an adult. As reported by Briggs, there have been reports of an increased risk of miscarriage and possibly infertility with higher caffeine doses.

Guarana is a caffeine-containing herbal supplement often found in energy drinks, and some medications may contain caffeine, too. Ernst and colleagues suggest Guarana may lead to low birthweight, birth defects, premature birth. Experts recommend guarana not be used in pregnancy. Another herbal product with stimulant properties known as ephedra should also be avoided.

General Use of Vitamin and Herbal Supplements

In general, it is best to avoid OTC herbal and dietary supplements in pregnancy. These products are not regulated by the FDA for safety and may have variable quality. Over-the-counter "natural" dietary supplements may contain unknown substances and few studies describing their use in pregnancy are available.

However, prenatal vitamins that contain iron, calcium and folic acid are important in pregnancy, so don't skip those supplements; take as recommended by your doctor. Regular over-the-counter supplements may not have the right dose of vitamins you need, so ask your doctor if you need a prescription.

It's Flu Season - Should I Get a Shot?

Certain vaccines are actually encouraged for pregnant woman. Vaccines that are inactivated (killed vaccines) may be given during pregnancy if needed. Vaccines that contain live viruses are not generally recommended. Suggested vaccines in pregnancy include the inactivated influenza shot, and the Tdap vaccine (tetanus toxoid, diphtheria toxoid and acellular pertussis). The FluMist nasal vaccine contains a live virus and should NOT be used.

If you're planning a pregnancy, talk to your health care provider beforehand about any vaccines you may need. Live vaccines should be given at least a month before attempting to get pregnant.

Is Any Amount of Alcohol Okay in Pregnancy?

There is no established safe level of alcohol (wine, beer, or liquor) you can drink during any trimester in pregnancy. Alcohol easily crosses the placenta. Studies have found higher rates of miscarriage, stillbirth, and birth defects with alcohol use during pregnancy.

Regular use or large amounts of alcohol during pregnancy can lead to Fetal Alcohol Syndrome, which can result in birth defects, and behavioral or learning problems. Be sure to check over-the-counter medication bottles for the presence of alcohol. If you are concerned that you cannot avoid alcohol intake during your pregnancy, speak with a health care provider as soon as possible.

Pregnancy During Allergy Season

First generation OTC antihistamines such as diphenhydramine (Benadryl) or chlorpheniramine (Chlor-Trimeton) are reported as compatible with pregnancy, and may be considered if an allergy medicine is needed in pregnancy. However, they do cause drowsiness.

Loratadine (Claritin) is a non-sedating antihistamine also used to relieve the symptoms of seasonal allergies like sneezing, runny nose, and watery eyes. Clinical data from Briggs shows that loratadine has a low risk for birth defects, adequate safety data, and may be a preferred choice over a sedating, 1st generation antihistamine. For many allergies in pregnant women, a corticosteroid nasal spray or allergy eye drop may be a 1st line option too, with low absorption into the bloodstream.

Can I Use My Acne Medication?

Over-the-counter (OTC) topical acne treatments are medications applied directly to the skin. Benzoyl peroxide, a common ingredient found in OTC acne medications, can be used during pregnancy as well as prescription topical clindamycin. These OTC topical acne products do not appear to increase the risk for birth defects in pregnancy as so little of the medication gets through the skin to the baby. It is safe to breast feed while using these products, as long as the product does not come into contact with the baby. See your dermatologist to discuss your options for control of acne during pregnancy.

The prescription drug isotretinoin (Accutane) should not be used in pregnancy due to the risk of birth defects. In fact, just one dose of isotretinoin can cause severe birth defects or death of a baby. Never use this medicine if you are pregnant or may become pregnant.

Stomach Symptoms in Pregnancy

Stomach complaints, such as heartburn, gas, and constipation are common in pregnancy. Heartburn is experienced by more than 50 percent of women in pregnancy. Simethicone (Gas-X, Mylanta Gas), an anti-flatulent for gas that is not absorbed into the bloodstream, is compatible with pregnancy. Lifestyle changes or calcium-based antacids (Tums) might be the best first choice, but the OTC acid blockers ranitidine (Zantac) or cimetidine (Tagamet HB) are also low risk in pregnancy.

Adequate fluids (water) and exercise is always important to combat constipation, but the stool softener docusate sodium (Colace) has been reported as compatible with pregnancy by Briggs et al. Fiber supplements, such as Metamucil or FiberCon can help with constipation in pregnancy, too, if okayed by your doctor.

In the Outdoors: How to Stay Bug-Free.

If possible, avoid mosquitoes and ticks while you are pregnant. Insect repellents are important to help avoid serious diseases such as malaria, West Nile Virus, or Lyme Disease which may be dangerous to both the mother and baby. According to the CDC, insect repellents registered with the EPA, such as DEET, can be used on pregnant women. To minimize exposure, use the lowest concentration of DEET to provide protection only for the time spent outdoors. Cover up if preferred - wear long pants and sleeves and apply DEET to clothes instead of skin to minimize exposure. To help prevent contracting Zika virus, follow the latest CDC guidelines on pregnancy, travel and Zika Virus. Recommendations change frequently and should be consulted by pregnant women before any international travel. Women of child-bearing age can protect themselves from mosquito bites by wearing long-sleeved shirts and pants, using mosquito repellent, and staying indoors when possible. Since Zika virus is sexually transmitted, women should use condoms if they live in an active Zika area. They should also follow these precautions for at least eight weeks if the man has traveled to an active Zika area, or for at least six months if the man has been diagnosed with Zika.
