Pregnancy and Medicines Summary Not all medicines are safe to take when you are pregnant. Some medicines can harm your baby. That includes over-the-counter or prescription drugs, herbs, and supplements. Always speak with your health care provider before you start or stop any medicine. Not using medicine that you need may be more harmful to you and your baby than using the medicine. For example, many pregnant women take prescription medicines for health problems like diabetes, asthma, seizures, and heartburn. The decision about whether or not to take a medicine depends on the risks and benefits. You and your health care provider should make this choice together. Pregnant women should not take regular vitamins. They may have too much or too little of the vitamins that you need. There are special vitamins for pregnant women. It is important to take 0.4 mg of folic acid every day before you become pregnant through the first part of your pregnancy. Folic acid helps to prevent birth defects of the baby’s brain or spine.
