Treatment
Treatment of gastritis depends on the specific cause. Acute gastritis caused by NSAIDs or alcohol may be relieved by stopping use of those substances. Chronic gastritis caused by H. pylori infection is treated by eradicating the bacteria. Most gastritis treatment plans also incorporate medications that treat stomach acid in order to reduce signs and symptoms you're experiencing and promote healing in your stomach.
Medications to treat stomach acid
Stomach acid irritates inflamed tissue in your stomach, causing pain and further inflammation. That's why, for most types of gastritis, treatment involves taking drugs to reduce or neutralize stomach acid, such as:
Antacids. Over-the-counter antacids (Maalox, Mylanta, others) in liquid or tablet form are a common treatment for mild gastritis. Antacids neutralize stomach acid and can provide fast pain relief.
Acid blockers. When antacids don't provide enough relief, your doctor may recommend a medication, such as cimetidine (Tagamet), ranitidine (Zantac), nizatidine (Axid) or famotidine (Pepcid), that helps reduce the amount of acid your stomach produces.
Medications to shut down acid 'pumps.' Medications called proton pump inhibitors reduce acid by blocking the action of tiny pumps within the acid-secreting cells of your stomach. This class of medications includes omeprazole (Prilosec), lansoprazole (Prevacid), rabeprazole (Aciphex) and esomeprazole (Nexium).
Medications to treat H. pylori
Doctors use several regimens to treat H. Pylori infection. Most use a combination of two antibiotics and a proton pump inhibitor. Sometimes bismuth (Pepto-Bismol) is added to the mix. The antibiotics help destroy the bacteria, and the proton pump inhibitor relieves pain and nausea, heals inflammation and may increase the antibiotics' effectiveness.
To ensure that H. pylori has been eliminated, your doctor may test you again after treatment.
