I was wondering about the side effects that propecia can cause. I started using propecia for the first time about 10 weeks ago. After five days I began feeling somewhat odd during diffrent situations like in public places or when hearing noises, kinda dizziness. The worst was after 8 days when the feeling was present almost all the time. When these symptoms started I quit using propecia for two weeks, and the symptoms still seemed to maintain, although after a week I felt better, and after a week that I had been off propecia, started the headaches. Because the symptoms did not seem to subside in two weeks (well, at least not all of them) I started propecia again. Now after six weeks, I still get somewhat dizzy during days, and feel kinda tired almost all the time plus I have headaches from time to time. I also used rogaine for five weeks, but because I started feeling elevated pulse and some arhytmia I stopped using it a week ago. I still feel little elevated pulse during days and stronger heartbeats, is this normal rogaine side-effect and how quickly should rogaine induced side-effects subside? What about propecia? Anyone had the same experiences?
