I have been on Aciphex for 8 days. Last night I couldn't sleep because I was so bloated that my stomach was so tight and it looked like I was pregnant. I also had alot of chest pain. It was very difficult to breath. It felt like a heavy weight on my chest. I had the same results from Prontix. The only thing different was my throat didn't swell. I was immediately taken off of Prontix because my doctor said it was an allergic reaction. Of course I stopped the Aciphex because I know how bad it can get. I would recommend if anyone is having any type of side effect to call their doctor. Better safe than sorry. As for me I am not trying another medication. Two times of a bad reaction is more than enough! I'd rather not take anything.
