I have been taking Finasteride for the last 10 months, following an FUE hair transplant. I was advised by the clinic to split the generic 5mg Finasteride tablet in two, and ingest 2.5mg of Finasteride every other day. I've only just recently read online that 2.5mg of Finasteride taken every other day holds no use, as it is short lasting and only remains in the body by by a few hours (possibly 5-6 hours). Can someone please advise myself on the best way to take the the 5mg Finasteride tablets please?
