Why do finasteride and dutasteride warn about pregnancy?

💡 Quick answer

A “just one touch” forum is not the label. Keep tablets intact; ask a pharmacist about handling.

U.S. labels for finasteride include pregnancy category language and crushed-tablet warnings. Dutasteride carries similar handling caution. This page will not invent a PMID. Related: finasteride-and-fertility — different URL.

Do not start oral finasteride in a home planning pregnancy without a prescriber conversation. Do not split tablets on a kitchen counter. Minoxidil labels have their own pregnancy/lactation text — another carton.

A pregnant person who handled crushed 5AR should call their clinician. This is not medical advice.

FAQ

Can I take 1 mg if my partner is pregnant?

Ask the prescriber. Handling crushed tablets is the labelled caution.

Is topical finasteride safer?

This page does not invent a safer compound. Compounded topicals are another risk file.

Same as fertility page?

Related 5AR family, different URL. This file is pictograms/handling.

More foam as a substitute in pregnancy?

Read the minoxidil carton and a clinician. Do not invent a stack.

Not medical advice. General education only; it does not replace diagnosis or treatment by a licensed professional. Figures such as 1 mg or 5% are labelled strengths you may see in your country — not a dosing instruction. Consult a board-certified dermatologist before starting, stopping or changing any treatment.
