Switching Finasteride from Generic to Proscar

First of all I am very thankful for the information you provide on this subreddit, it is invaluable to me and a lot of other people.  About two months ago I got prescribed a generic propecia 1 mg from my dermatologist here in Sweden. As a student at university I can cover the cost but Im interested in changing to Proscar 5 mg and then splitting them. After a lot of reading I´ve understood that there is no difference between the two except that Proscar is a lot cheaper.

My concern is that I read about people claiming that swapping between difference finasterides ruined their hair. Personally I have difficulties seeing it making a difference, but I would of course never forgive myself if my chase after saving a couple of dollars ended up making my hair even worse.  So my question to you is, do you have any personal experience from your patients changing medicine? If yes, did it harm their hair in any way or did it just continue as usual?

Thank you for taking your time,

No problem. Switch it without worry!
