Care Plan


First steps to consider

  • See a healthcare provider to find out what is causing your acute gastritis and to get prescription medication if needed.
  • OTC medications like proton pump inhibitors, antacids, histamine blockers, and bismuth subsalicylate can help relieve stomach pain and nausea that’s not caused by the H. pylori bacteria.

When to see a healthcare provider

If you think you have acute gastritis, you should always see a healthcare provider. Gastritis is often caused by an H. pylori infection, which can’t be treated with just home treatments.

If tests show you have H. pylori, your doctor will prescribe medication to treat the infection. They may also prescribe medication to reduce the amount of acid in your stomach.

How to test for acute gastritis

Your healthcare provider may diagnose acute gastritis based on your symptoms and a physical exam. But they may order tests to figure out what’s causing it. Tests may include a stool, breath, or blood test. In some cases, your doctor may want to do an upper endoscopy to examine your stomach lining and to remove a sample (biopsy) of stomach tissue. You will need to be sedated.

What to expect from your visit

  • If H. pylori bacteria is the cause, you will be prescribed antibiotics for 10–14 days.
  • Your doctor may prescribe a proton pump inhibitor to reduce the amount of acid in your stomach.

Prescription medications

  • Antibiotics: clarithromycin (Biaxin XL), amoxicillin (Augmentin), metronidazole (Flagyl)
  • Proton pump inhibitors: rabeprazole (Aciphex), pantoprazole (Protonix)

Types of acute gastritis providers

  • A primary care provider can treat acute gastritis.
  • Gastroenterologists, who specialize in treating the digestive system, can do additional testing and may know about other treatment options.
