H. pylori infections are usually treated with two varieties of antibiotics at once, to help prevent the bacteria from developing a resistance to one particular antibiotic. Your doctor also will prescribe an acid-suppressing drug, to help your stomach lining heal.
Drugs that can suppress acid include:
- Proton pump inhibitors (PPIs). These drugs stop acid from being produced in the stomach. Some examples of PPIs are omeprazole (Prilosec, others), esomeprazole (Nexium, others), lansoprazole (Prevacid, others) and pantoprazole (Protonix, others).
- Histamine (H-2) blockers. These medications block a substance called histamine, which triggers acid production. Examples include cimetidine (Tagamet) and ranitidine (Zantac).
- Bismuth subsalicylate. More commonly known as Pepto-Bismol, this drug works by coating the ulcer and protecting from stomach acid.
Your doctor may recommend that you undergo testing for H. pylori at least four weeks after your treatment. If the tests show the treatment was unsuccessful, you may undergo another round of treatment with a different combination of antibiotic medications.
