Pregnancy Warnings

Drugs Safe In Pregnancy Chart

Although some medicines are considered safe during pregnancy, the effects of other medicines on your unborn baby are unknown. Certain medicines can be most harmful to a developing baby when taken during the first three months of pregnancy, often before a woman even knows she is pregnant.

Available data indicate that more than 50% of pregnant women take prescription or nonprescription (over-the-counter) drugs or use social drugs (such as tobacco and alcohol) or illicit drugs at some time during pregnancy, and use of drugs during pregnancy is increasing. In general, drugs should not be used during pregnancy unless necessary because many can harm the fetus. Less than 2 to 3% of all birth defects result from drugs that are taken to treat a disorder or symptom.

Are natural or alternative remedies safe to use during pregnancy?

Just because a product is labeled “natural” doesn’t necessarily mean it’s safe to take during pregnancy. Like any drug, some natural remedies are considered low risk in pregnancy and some aren’t.

The biggest challenge with determining the safety and effectiveness of natural or alternative remedies is that many haven’t yet been studied in pregnant or breastfeeding women, so the risks are simply unknown. Also, many natural and homeopathic remedies aren’t well regulated, so it’s difficult to know exactly what’s in them.
