If you have an ulcer, you should be tested for H. pylori, and if found to be infected, you should be treated with antibiotics. Antibiotics offer a new cure for ulcers; therapy is 1-2 weeks of one or two antibiotics plus a medicine that will reduce the acid in the stomach. This treatment is a dramatic medical advance because eliminating H. pylori with antibiotics means that there is a greater than 90% chance that the ulcer can be cured for good. Remember, it is very important to continue taking all of this medicine until it is gone, even when you begin to feel better. If you are having side effects that make it hard to take your medicine, talk to your health care provider.
