Hi, I have been on Prozac for 3 years and am presently being switched to Zoloft.
The Prozac just wasn't helping me anymore.
Presently I am being weaned off the Prozac, cut from 40mg, to 20mg, and now a week without, and then starting the Zoloft in a week.
Maybe your doctor doesn't think the Prozac is helping you like it should.
If you have questions or concerns about the medication change, maybe you should mention it to your doctor, tell him your concerns.
I did tell my doctor I wanted something that would not make me gain weight, and we felt the Zoloft would be the best choice for me, but only time will tell.
I have heard nightmares about many AD, everybody is different and everyone reacts differently to them.
This is just my 2 cents!
Wishing you well.
