5-alpha-reductase inhibitor (type II)
Finasteride and pregnancy: what we know
Pregnancy and breastfeeding are special periods where every medication choice deserves careful review. Finasteride (Finasteride) is no exception. The prescribing information for Finasteride provides specific guidance, and the right decision depends on the indication, alternatives, gestational stage and the woman's overall medical picture.
Pregnancy safety data for Finasteride
According to the prescribing information for Finasteride, the available human data in pregnancy may be limited, supportive, or restrictive depending on the molecule. Some 5-alpha-reductase inhibitor (type II) agents are routinely used in pregnancy when needed; others are avoided. The risk-benefit calculation includes the importance of treating the underlying condition and the consequences of leaving it untreated.
Breastfeeding considerations
Breastfeeding considerations are usually separate from pregnancy considerations. Some active ingredients pass into breast milk in negligible amounts; others are present at levels that warrant caution. Finasteride binds with high affinity to 5-alpha-reductase type II, blocking the conversion of testosterone into DHT. The prescriber weighs the benefit of breastfeeding, the importance of Finasteride, and the availability of alternative therapies.
