Uc Rab 20 Tablet is used for treatment of acid-related disorders such as gastroesophageal reflux disease (GERD), heartburn/acid reflux, erosive esophagitis, gastric and duodenal ulcers; part of combination therapy for Helicobacter pylori eradication; Zollinger–Ellison syndrome.
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Rabeprazole is a proton pump inhibitor (PPI) that irreversibly blocks the H+/K+ ATPase (proton pump) in gastric parietal cells. This reduces stomach acid production, helping relieve symptoms and allowing ulcers and esophageal irritation to heal.
Oral tablet. Take as prescribed, usually once daily (20 mg) preferably 30 minutes before food, ideally before breakfast. Swallow whole with water; do not crush or chew. For H. pylori regimens, take along with prescribed antibiotics as directed.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of U Rab 20mg Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
Taking more Uc Rab than prescribed can be harmful. If you suspect an overdose, contact a doctor or go to the nearest emergency department at once, and carry the pack or strip with you. In India the emergency number is 112.
Most side effects of Uc Rab are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.
