If prozac worked for 3 years on a teenager, but then stopped, Would it work again?

Well Wintergreen...there is only one way to find out and that is to try it again.  It does seem that with some of these anti-depressants, you build up a tolerance for them. 

Talk to your doctor about taking it...and think about what dosage is appropriate.  And also have Plan B in mind if the Prozac doesn't work again.

Let us know what happens...I am very curious.  Hopefully others can chime in with their experience.

Thank you for your question!

Hello, wintergreen,

I don't have any experience with Prozac, but I can tell you that I've had other medications stop working, but then work again after a break from them.

Prozac is rather infamous for working for a while, then not working. The phrase "Prozac poop-out" is sometimes used, even when the medication being discussed isn't Prozac.

Good luck,

Teri
