What is the proper taper for Prozac?

Hi, emcs!
I'm sorry you're having these side effects! 20mg may be too much for your metabolism yet. It's pretty standard to drop to a lower dose temporarily to see if you tolerate it better. You may find it effective at the lower dose or you may need to increase it again in the future.
Great that you're looking for advice rather doing something like trying to do it yourself or worse stopping abruptly. I'd say give it a shot as the NP advised.
Best wishes, Wildcat
Give us an update if you don't mind.

Hi,

I was on Prozac (fluoxetine) a long time ago, so you know I am familiar with this AD.

I am not a Dr., and everyone reacts differently to everything in life, having said that, cutting it by half in my opinion is too much, too fast, I suggest until you talk to your prescriber you go down to 15mgs..

Best of luck, masso
