What should I watch for while using this medication?
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. Finish the full course of tablets prescribed, even if you feel 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 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.
This medicine may cause a decrease in vitamin B12. You should make sure that you get enough vitamin B12 while you are taking this medicine. Discuss the foods you eat and the vitamins you take with your health care professional.
