Three stamps. The cautious one wins.
Avoid while pregnant: an FDA label, the AAD, ACOG or a peer-reviewed review advises against it. Ask your doctor first: a source says to limit it or to check with a doctor, the sources we read disagree, or we found too little to go on. Generally considered OK: every source we read that covers it says it can be used. No stamp replaces your OB-GYN.

What the sources say
The AAD lists it with isotretinoin and tazarotene as acne medicines that can cause serious birth defects: if you’re pregnant, stop it immediately.

Why it’s on the never list
Spironolactone is a blood pressure pill, a potassium-sparing diuretic, that dermatologists also use for acne, female hair loss and excess hair growth. MotherToBaby explains the concern: animal studies suggest that taking it early in pregnancy might cause feminization of male offspring. Whether that happens in people isn’t known; there are case reports of children born without birth defects, and some with reduced male development. Product labels disagree on how strictly to avoid it.
What about breastfeeding?
MotherToBaby says spironolactone passes into breast milk in small amounts that are not expected to cause side effects in most nursing babies. It suggests calling your baby’s doctor if the baby seems unusually sleepy or has trouble feeding.
