Effective Treatment for Heartburn, Acid Reflux & Indigestion
Omeprazole is a proton pump inhibitor (PPI) used to treat symptoms of acid reflux, heartburn, indigestion, and gastric ulcers. It works by reducing the amount of acid produced in the stomach, offering long-lasting relief from discomfort and helping prevent acid-related damage.
Available in 20mg strengths.
What Does Omeprazole Treat?
Omeprazole is effective for:
Acid reflux (GORD)
Heartburn
Indigestion (dyspepsia)
Stomach ulcers
Preventing ulcers caused by NSAIDs (e.g. ibuprofen)
It works by blocking the proton pumps in the stomach lining that produce acid, providing relief and allowing healing.
