How does rabeprazole work?
Rabeprazole blocks the proton pumps in the stomach lining, preventing excess acid production and allowing the stomach lining to heal.
What is rabeprazole used to treat?
Rabeprazole is commonly prescribed for:
- Gastroesophageal reflux disease (GERD) (to reduce acid reflux and heartburn)
- Stomach and duodenal ulcers
- Preventing ulcers caused by NSAIDs (such as ibuprofen and aspirin)
- Zollinger-Ellison syndrome (a rare condition causing excessive stomach acid production)

Can I take rabeprazole if I’m pregnant or breastfeeding?
Rabeprazole may be used during pregnancy and breastfeeding, but always consult your doctor before use.
What if I miss a dose?
