What should I watch for while using this medicine?
Tell your doctor or health care professional if your condition does not start to get better or gets worse. You may need to take this medicine for several days as prescribed before your symptoms get better.
Do not smoke cigarettes or drink alcohol. These increase irritation in your stomach and can lengthen the time it will take for ulcers to heal. Cigarettes and alcohol can also make acid reflux or heartburn worse.
If you need to take an antacid you should take it at least 1 hour before or 1 hour after this medicine. This medicine will not be as effective if taken at the same time as an antacid.
If you get black, tarry stools or vomit up what looks like coffee grounds, call your doctor or health care professional at once. You may have a bleeding ulcer.
