I took Aciphex for 3 days and stopped. Two days later I awoke with a very scary irregular heartbeat that lasted for 2 hours and accompanied by frequent urination for the two hours. I was petrified. I thought I was dying! Now I am scared to take any more Aciphex. I only have GERD or Dyspepsia infrequently. I will try to find a natural remedy. I also had a headache every time I took the Aciphex. I did not have any bowel changes that I noticed but I was only on it for 3 days. I had none of the other symptoms mentioned.
