Rabeprazole: Uses, Dosage, Side Effects and More
Introduction: What is Rabeprazole?
Rabeprazole is a medication belonging to a class of drugs known as proton pump inhibitors (PPIs). It is primarily used to reduce stomach acid production, making it effective in treating various gastrointestinal conditions. By inhibiting the proton pump in the stomach lining, Rabeprazole helps alleviate symptoms associated with excessive stomach acid, such as heartburn and acid reflux.
Uses of Rabeprazole
Rabeprazole is approved for several medical uses, including:
- Gastroesophageal Reflux Disease (GERD): It helps manage symptoms of GERD, a condition where stomach acid frequently flows back into the esophagus, causing heartburn and irritation.
- Peptic Ulcers: Rabeprazole is used to treat peptic ulcers, which are sores that develop on the lining of the stomach or the first part of the small intestine.
- Zollinger-Ellison Syndrome: This rare condition involves excessive acid production, and Rabeprazole can help control acid levels.
- Helicobacter pylori Eradication: It is often used in combination with antibiotics to help eliminate H. pylori, a bacteria linked to stomach ulcers.
How It Works
Rabeprazole works by blocking the proton pump in the stomach lining, which is responsible for producing stomach acid. By inhibiting this pump, Rabeprazole effectively reduces the amount of acid produced, leading to decreased acidity in the stomach. This helps relieve symptoms of acid-related conditions and promotes healing of the stomach lining.
Dosage and Administration
The standard dosage of Rabeprazole varies based on the condition being treated:
- Adults:
- For GERD: 20 mg once daily for up to 48 weeks.
- For peptic ulcers: 20 mg once daily for 46 weeks.
- For Zollinger-Ellison syndrome: Initial dose of 60 mg, adjusted based on response.
- Pediatrics:
- For children aged 12 years and older: 20 mg once daily for GERD.
- Dosage for younger children is determined by a healthcare provider.
Rabeprazole is typically taken orally in the form of a delayed-release tablet, usually before a meal. It is important to swallow the tablet whole and not crush or chew it.
Side Effects of Rabeprazole
Common side effects may include:

Serious side effects can occur, though they are less common:

If any severe side effects occur, it is crucial to seek medical attention immediately.
Drug Interactions
Rabeprazole can interact with several medications, including:
- Clopidogrel: May reduce the effectiveness of this blood thinner.
- Methotrexate: Increased levels of methotrexate can occur, leading to toxicity.

- Certain antifungals: Such as ketoconazole, which may have altered absorption.
Always inform your healthcare provider about all medications and supplements you are taking to avoid potential interactions.
