Finasteride (Propecia): what are the side effects?
Finasteride is used in 1mg doses to treat male hair loss. Sometimes Finasteride is prescribed under the brand name Propecia. In a 5mg dose, Finasteride is also used to treat benign prostatic hyperplasia (BPH), or an enlarged prostate. The 5mg dose isn’t any more effective for hair loss than 1mg.
Side effects from Finasteride are not common, but like all medications, are possible. It’s good to be aware of what side effects could occur, so you know what to look out for. If you notice any side effects while taking Finasteride, you should talk to your clinician.
