Your doctor may prescribe medicines to neutralize or reduce extra stomach acids. These may include antacids, H2 blockers, and proton pump inhibitors. Sometimes a medicine such as sucralfate is used to help the stomach's protective lining. If tests show that H. pylori bacteria are in your stomach lining, you may get antibiotics even if you don't have symptoms. H. pylori can cause gastritis. If gastritis has caused low vitamin levels, you may need to take supplements.
