Minoxidil topical use

Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

An antihypertensive vasodilator used in the form of a 2%-5% topical solution in androgenetic alopecia.

The small dose and low plasma absorption of most topical dermatological preparations make transfer in significant amounts into breastmilk very unlikely.
Only 1.4% (0.3-4.5%) of minoxidil reaches blood plasma when it is used topically on the skin (Butler 2014, Johnson 2014, Galderma 2013).

Minoxidil taken orally is excreted in breastmilk in clinically insignificant amounts and no problems have been observed in an infant whose mother was taking it (Valdivieso 1985).

It is normal to lose hair in the months following pregnancy and this has nothing to do with breastfeeding but with stopping the resting phase in hair loss that occurs during pregnancy. Within 12 months after delivery, the hair grows back without leaving alopecia.

American Academy of Pediatrics: medication usually compatible with breastfeeding (AAP 2001).

We do not have alternatives for Minoxidil topical use since it is relatively safe.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
