I have read that some men start to add dutasteride after years being on finasteride. But I haven't read any reports that show that finasteride somehow stops working as effectively the longer you are on it. I also can't see how that would be possible given the science but I'm no expert.
So are there clinical studies out there that finasteride's effectiveness wanes over time?.
I ask because I've been on finasteride for 10 years.
thank you.
