What;'s Safe to Take?

WebMD has an excellent article on this subject with a table listing many "safe" medications - those considered to be safe in pregnancy.

Because we don't do the usual testing of drugs in pregnancy and lactation, we do not have the usual data confirming safety and the manufacturer of the medications must not claim such safety due to the regulations of the FDA regarding testing. However, we have learned much about this because after thousands of women have exposures during pregnancy, either because they didn't know they were pregnant or because their condition warranted the medication in consideration of the risks and benefits, we have good resources. Organizations like OTIS (Organization for Teratology Information Services) and our local Pregnancy Risk Line gather information and are available to inform women about the medication they are considering and whether or not it is likely to increase the risk of having a child with a birth defect. Few drugs have actually been shown definitively to cause defects, such as Accutane (isotretinoin) and thalidimide.

PRL number is (801) 328-2229 (328-BABY) or (800) 822-2229 (822-BABY). These experts are available for questions about specific medication or other exposures in pregnancy or while breastfeeding. If you don't get through, leave a message and they will return your call.

The safe course is always to avoid any unnecessary exposures in pregnancy since it is impossible to know every possible concern - either for the mother or the baby - and you should always discuss medications, supplements, and herbal treatments with your doctor or nurse midwife.
