The bar for using medications and supplements during pregnancy is very high, generally avoiding anything not essential beyond prenatal vitamins or necessary hormones.

“Most physicians, myself included, though I don't treat very many pregnant women, think about drugs and supplements very differently in the setting of pregnancy. Of course, because we are typically not treating patients with life-threatening conditions, our mantra is during pregnancy, women should basically stop all medications and supplements beyond the obvious ones such as prenatal vitamins or hormones such as thyroid hormone, which can be essential. But anything that's even in a gray area or probably okay, we tend to just avoid.”
