Dutasteride vs finasteride

I have being taking finasteride for a year with no side and I think I made some nice progress  but 3 month ago I asked my doctor about trying dutasteride since I didn’t have any side with finasteride. My reason was : didn’t get side so might as well get the stronger stuff and also even if my hair got better I still feel like I’m losing 100+ hairs everyday, maybe 120/150 so I was thinking that maybe I wasn’t doing enough. Long story short I started getting some small sides 1month ago with dutasteride feeling really horny, not too bad I guess but mostly I was not as hard/would be difficult to do it twice in a row. So I stopped taking it for around 1month and started finasteride again and it’s back to normal. My question is do you think with the progress I made with finasteride I should be fine for the long run? I feel this is the smart choice but I can’t remove the small voice in my head saying to try to ease back into dutasteride.  Thank you.

I take it that your side effects was an increased libido, something I see with some frequency with people starting finasteride. Dutasteride is not FDA cleared so I generally avoid it. Another reason is its long half life (4-6 weeks) when compared with finasteride (4-5 hours). The gain of 15% effectiveness reflects that its blocking impact is 85% at the 5 alpha-reductase level while finasteride is 70% effective. If you have good effects with finasteride, stick to it
