Treatment aims to reduce the amount of acid in the stomach to relieve symptoms, allowing the stomach lining to heal and to tackle any underlying cause.
You may be able to treat gastritis yourself, depending on the cause.
- antacids – these over-the-counter medicines neutralise the acid in your stomach, which can provide rapid pain relief
- histamine 2 (H2) blockers – these medicines decrease acid production and are available to buy from your pharmacist and on prescription
- proton pump inhibitors (PPIs), such as omeprazole – these medicines decrease acid production even more effectively than H2 blockers
Some low-dose PPIs can be bought from your pharmacist without a prescription.
You'll need a prescription from a GP for stronger doses.
Treating H. pylori infection
If an H. pylori infection is the cause of your gastritis, you'll need to take a course of antibiotics alongside a proton pump inhibitor.
