duodenal ulce
"I have both an ulcer in my stomach as well as duodenitis (two ulcers in the upper part of my small intestine)--this was all discovered during my endoscopy. I was given this medication and am still on it...immediately I had dry mouth, mild headaches and that dizzy/vertigo feeling which I just thought were my sinuses acting up until I looked up the side effects. It's changed my bowel motions for sure, more towards constipation which then causes an upset stomach for me, mainly in the morning."
