Hey guys, I've been on generic finasteride at 1mg/day for about 2 years now to keep my hairloss under control. About 6 days ago I ran out of finasteride and did not pick any more up until 3 days ago. During that 3 day period my nipples swelled up quite a bit and I've been freakin' about it. I know that propecia can slightly increase estrogen levels but why would coming off propecia for a few days do this?
