Efficacy of Finasteride at 0.25mg every day? Also have any of your patients suffered persistent or Irreversible side effects?

Question

I am considering adding finasteride to my regimen. I've read somewhere that anything above 0.2 mg is as almost as effective as 1 mg in inhibiting DHT.

The recommended dose of finasteride for male pattern balding is 1mg per day.  Speak to your doctor before staring the medication.You generally start with the recommended dose.You generally don't start with a lower dose because you are scared of possible side effects.The actual sexual side effect we have seen from thousands of our personal patients over 15+ years are about 1 to 2%.  None of them reported irreversible side effects.

Jeff Rapaport, MD · Answer

In my opinion, lowering the dose on finasteride is less effective than taking the 1 milligram dose. When a drug company releases a medication, they do studies to determine the minimal dose that produces a good response. There is a dose-response curve with an finasteride . If you use one quarter of the strength, you probably will get somewhere between 20 to 35% of the results. My suggestion would be to use the full dose and determine if you have any side effects. You can always back down on the dose at a later time. Hope this helps. Good luck.

The actual numbers from the original studies on finasteride is as follows for daily doses: 1mg ideal and best dose0.5 mg is 80% as effective0.25mg is 50% as effectiveYou are talking about taking 0.25mg every other day and I suspect it would be half as effective as the daily dose discussed above. No, I have not seen any irreversible sexual side effects from people who stopped finasteride
