Paxil worked wonders for preventing panic attacks. So much so that I thought I was "cured" and slowly stopped taking them. The next dr gave me Celexa, which didn't seem to help at all.
They both gave me daily, almost constant headaches.

Prozac doesn't give me any side effects, but personally I don't think it's as good as Paxil for panic attacks. I asked to go back to Paxil and endure the headaches, but my pdoc thinks it causes more weight gain than Prozac.
