I was prescribed Paxil for panic disorder and took only one pill and within a half hour my stomach was very upset. Later that night I started throwing up, among other things, and ended up calling the hospital. They told me this was normal with the drug and when I called my regular doctor this morning she advised me to stop taking it and drink lots of fluids. I was just wondering if this happened to anyone else and if so how long will these horrible side effects last for? It's been 24 hours since I took the pill. I feel miserable.
