I genuinely don't think that's the way it works. In fact it seems to generally be the case that you adjust to the medication over time.The same happened to me as well no erection problems on finasteride took dutasteride for 2 days the second day i got weak erections
it made me scared that i might end up with weak erections on finasteride as well and it's just a matter of time
do you think people who got sides from dutasteride won't be the same on finasteride?
I'm fine in that department now. I just have the nose/cough problem to sort out.
