Angina
"I was given Ranexa by my Physician Assistant for some minor chest pain. I took 4 doses of Ranexa (500 mg) as prescribed. I experienced dizziness, was light headed. That evening about midnight while I was in bed I had uncontrollable diarrhea, headed to the bathroom, changed pajamas and immediately had uncontrollable diarrhea again. Returning to bed I experienced the uncontrollable diarrhea while asleep.  I did not take any more and ended up in the hospital emergency room severely dehydrated. I was there two days with numerous tests. After this experience, I would never take this again. I destroyed the rest of the pills."
