Marijuana and Finasteride

hello doctor, i was wondering, does marijuana effect the side effects or progress of Propecia at all? that’s it, thank you.

I read so many concerns from people in emails and other various corners of the internet about the negative sexual side-effects of Propecia. Yet you ask about the effects of marijuana, which in itself gives you a low libido and other negative sexual side effects. So if you are a worst case scenario type of person, your chances of a negative sexual side effect most probably more than doubles. We also know that there are reports that marijuana may contribute to hair loss either directly or indirectly.

There is no interaction between marijuana and Propecia.
