I recently got a precription to Propecia 1 mg. I noticed my first day of taking the drug I was perfectly fine, however the next day I experienced a super low libido, difficulty getting erections, my penis was like desensitized, and I had what others have described as “brain fog”, where I felt as if I had a buzz of alcohol and couldn’t focus well. I stopped after the second day and want to know if effects occur usually within 2 days? Also, with it only being 2 days, would there be any long term effect? Thanks a lot.
Yes I had side effects within 3 days, the exact ones you described in terms of genital numbness, ED, loss of libido etc. If you’ve only taken it 2 days, you should most likely be fine in the coming few weeks.
My advice: do NOT take it again, you are obviously a bad responder like others here but unlike you, many continued on believing Merck’s claims that side effects would resolve with continued use or definitely after quitting.
Be glad you found out right away that you are prone to these issues and take it as a sign not to continue. If you have further questions on what the drug does to your body, read the Finasteride Studies section.
Cheers.
