What is a key safety consideration when prescribing finasteride for androgenetic alopecia in men?

• A. Female partners of reproductive potential should avoid handling the tablets to prevent fetal exposure; not for use in women.
• B. There are no safety concerns for pregnancy.
• C. It is a topical cream; systemic exposure is minimal.
• D. It cures hair loss with no need for follow-up.

Answer: (A)

Finasteride is an oral 5-alpha-reductase inhibitor that lowers dihydrotestosterone (DHT) to treat male pattern hair loss. Its ability to affect fetal development is the key safety concern: if a pregnant woman, particularly one who could become pregnant, is exposed to the drug—especially through handling broken or crushed tablets—the active agent can be absorbed through the skin and potentially cause birth defects in a male fetus. Therefore the important precaution is that female partners of reproductive potential should avoid handling the tablets to prevent fetal exposure, and the drug is not appropriate for use in women. The fact that it’s taken orally with systemic exposure explains why contact precautions during handling matter. The other statements aren’t accurate because finasteride is not a topical cream, there are real pregnancy safety concerns, and it does not guarantee a cure with no follow-up.
