Some of the causes will go away over time. You may need to stop taking aspirin, ibuprofen, naproxen, or other medicines that may be causing gastritis. Always talk to your health care provider before stopping any medicine. You may use other over-the-counter and prescription drugs that decrease the amount of acid in the stomach, such as:Antacids H2 antagonists: famotidine (Pepsid), cimetidine (Tagamet), and nizatidine (Axid) Proton pump inhibitors (PPIs): omeprazole (Prilosec), esomeprazole (Nexium), iansoprazole (Prevacid), rabeprazole (AcipHex), and pantoprazole (Protonix) Antibiotics may be used to treat chronic gastritis caused by infection with Helicobacter pylori bacteria.
