I have been taking Propecia for over 10 years, and it has been great for slowing my hair loss. Now my doctor is recommending that I try a higher dose of finasteride for BPH. Will a 5mg daily dose of finasteride still have the effect of slowing my hair loss?
1mg strength (Propecia) is all the finasteride you need for treating androgenic alopecia (AGA). Taking a higher dose of finateride will not be of benefit with respect to treating your hair loss. I do realize that there are a minority of patients who choose to take a higher dose, but the results are equivocal at best.
Please follow up with your physician and address your BPH issues. A higher dose may give you a slightly higher risk of side effects, but it would not have a negative impact with respect to your hair loss. Essentially, taking the 5mg for BPH treatment would also give you hair loss treatment benefits.
