Well I've been on Fincar for almost a month (currently in my 4th week of treatment). I'm 21 and have a norwood 2.5, been on rogaine for a year and recently added nizoral and finasteride. I havent had any sides from fincar, and my question is am i likely to encounter any if i havent already? im wondering if theres any studies that show percentages of people who have sides after not experiencing any in the first month. i know its hard to say and that i may get sides a year down the road, but is it less likely to ever get them if i dont get them within the first month?
