Is Propecia Really safe?

[Taka4312]

I have a history of sexual side effects from propecia, including no more erections during the morning, and difficulty maintaining one even if I manage to get one in the first place. I stopped eventually, but realizing that it was my last hope for stopping hairloss as rogaine and lasercomb didn't work either, I started taking propecia again, but this time .5 mg every other day to start. Still, I am experiencing side effects as close to one and a half weeks following the start of my regimen.

So I have 3 main worries/questions.

1) if I am getting side effects, should I carry on taking drug, and what percentage of men are able to get over the side effects after continued use.

2) There is news on the web of a Swedish Medical Products agency concluding a safety investigation of Propecia, advising that sexual side effects may be persistent even after the stopping of Finasteride intake.
Wikipedia has even noted it in its side effects column.

3) Even if Propecia is FDA approved, its Longer term effects are still unknown. Seeing as it was only introduced in 1997, it is still a relatively new and untested drug.

So in the end, is PROPECIA REALLY SAFE? I ask myself - what will i do now if in a few years I am both bald AND impotent? Are there other people out there who worry about the severity of these consequences?

Thanks for your time everyone.
