I have been on Propecia for 11 years and am in the process of tapering off. My sides have increased but are not bad - thanks to this site for helping me realize they will continue to get worse unless I quit.
One concern I have not seen discussed is the effect of quitting on prostate cancer cells. I have seen talk on other sites suggesting that hair follicles experience androgen upregulation in response to finasteride (although I dont think anyone knows for sure). Could prostate cancer cells also become more sensitive to DHT while on propecia and therefore grow quickly once off the drug? I am 33 years old so I hope I dont have any cancer cells but I suppose you never know.
Anyone have any thoughts, seen any research, or have any supplement suggestions to take while tapering off?
