What medications are safe to take during pregnancy?

From the moment you get the happy news—that you’re an expectant parent—your priority is doing what’s best for your child. An important part of keeping a growing baby healthy during pregnancy is learning which medications are safe to take.

Birth defects occur in 3 to 5 out of every 100 pregnancies. This is called the background rate. Drugs considered safe during pregnancy are those that are not believed to increase the risk of birth defects.

It’s important to note: You should not take any medication (even one listed below as safe) without consulting your doctor or pharmacist. Everyone’s health situation is different. If you have any of the health issues below while pregnant, or while you’re trying to become pregnant, a medical professional will be able to recommend the best treatment plan for your specific circumstances.
