I am concerned about switching from Finasteride to Dutasteride. I have heard some negative feedback about Dutasteride and side effects. I have been taking 1.5mg of Finasteride for about 7 years. I feel like it's stopped working..? Is this possible. A reputable HT Doc suggested I switch to 0.5mg of Dutasteride AND 0.5mg of oral Minoxidil. Your thoughts please..?
