What is over-the-counter medicine?

Lots of women use over-the-counter (also called OTC) medicine, like pain relievers and cold medicine, to treat common conditions like a headache or a stuffy nose. Over-the-counter means you can buy the medicine without a prescription from a health care provider. But not all OTC medicines are safe to use during pregnancy. This goes for supplements and herbal products, too. 

If you’re pregnant, check with your health care provider before you take any over-the-counter medicine, supplement or herbal product to make sure it’s safe for you and your baby. 

Are over-the-counter medicines safe to take during pregnancy?

It depends. The label on most OTC medicine says that pregnant women should talk to their health care provider before using. This is because some OTC medicines may cause problems during pregnancy. For example, the pain reliever aspirin (such as brand name Bayer®) may increase your chances of having bleeding problems during pregnancy or childbirth. The pain reliever ibuprofen (such as brand name Advil®) can cause serious blood flow problems to your baby during the last 3 months of pregnancy. 

Most pregnant women can take acetaminophen (such as Tylenol®) to relieve pain if they follow the directions on the product label. But taking too much can lead to liver damage. 

Talk to your health care provider before taking any over-the-counter medicine to be sure it’s safe for you and your baby.

Are supplements safe to take during pregnancy?

It depends. A supplement is a product you take to make up for certain nutrients that you don’t get enough of in the foods you eat. For example, you may take a vitamin supplement to help you get more vitamin B or C. Or you may take an iron or calcium supplement. 

All pregnant women should take a prenatal vitamin with 600 micrograms of folic acid in it every day. Most prenatal vitamins contain this amount. But talk to your health care provider before taking any other kind of supplement. Some supplements may have too much or too little of the nutrients you need. And some may not be safe to take during pregnancy.

Are herbal products safe to take during pregnancy?

We don’t know for sure. An herbal product is made from herbs. An herb is a plant that is used in cooking or for medicine. Examples of herbal products are green tea and Gingko biloba.There’s very little research on how herbal products may affect pregnancy. So it’s best not to use them while you’re pregnant.
