After only 3 doses, I developed severe stomach pains, extreme waves of nausea where I broke out in a cold sweat and nearly passed out. I'm 56 and I have never had indigestion in my life..........I started having it then. The pain from my stomach all the way down was so bad I thought I would have to go to the emergency room. I've been off the medication now for a week and am still having the stomach problems. I believe the drug damaged my esophagus and stomach and possibly my intestines.
