Biotin and Propecia

Dr. I’ve been on propecia for almost 3 years I am 24 years old…so far its been working. I’ve just learned about Biotin. Will it be ok to take Biotin and Propecia at the same time? If you do recommend taking both at the same time what dose of Biotin should I take and for how long? My girlfriend takes 10000mcg for 4 months and her hair looks great.

Thanks

There is no problem taking biotin with Propecia (finasteride 1mg). The U.S. Recommended Dietary Allowance (RDA) for biotin is 300 micrograms daily. For more about Vitamin H (biotin), see this article at Medline Plus.
