How effective is acid reflux medication for peptic ulcer?

A peptic ulcer is a break in the lining of the stomach or the first part of the small intestine. Lowering acid can reduce further irritation and give the damaged lining an opportunity to heal. The medicine may therefore be useful even when the person does not describe classic heartburn.

An ulcer can be linked with Helicobacter pylori infection or regular use of anti-inflammatory pain medicines. Acid suppression alone may not remove an infection or address a medicine-related risk. Pain relief does not confirm that the ulcer has healed.

Follow the prescribed course and tell your clinician about painkillers, steroids, blood thinners, allergies and other medicines. Do not stop a prescribed medicine or start an over-the-counter product without checking first. Avoid alcohol and smoking if they worsen your symptoms, and use only pain relief that has been discussed.

Arrange follow-up if discomfort persists, returns, or is accompanied by ongoing indigestion. Your clinician may need to investigate the cause and decide whether further checks are needed. Read [Peptic Ulcer](/conditions/peptic-ulcer/) and [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/) for background.

Get emergency help for vomiting blood, black or tar-like stools, sudden severe abdominal pain, fainting or marked weakness. Seek prompt advice for repeated vomiting, worsening pain, difficulty swallowing or unexplained weight loss.

Ask what caused the ulcer, how long treatment should continue, whether any current medicine raises bleeding risk, and what follow-up will show that healing is progressing.
