Rabeprazole 20 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Rabeprazole 20 mg?

Rabeprazole 20 mg is a prescription proton pump inhibitor (PPI) used to reduce the amount of acid produced by the stomach. It is commonly prescribed to treat conditions caused by excess stomach acid, including gastroesophageal reflux disease (GERD), stomach ulcers, and other acid-related disorders.

Rabeprazole works by blocking the stomach’s acid-producing pumps, providing long-lasting acid suppression that helps relieve symptoms and promote healing.

It is available in several strengths, including:

• 20 mg delayed-release tablets
• 10 mg delayed-release tablets (in some countries)

How Rabeprazole Works

Rabeprazole blocks the hydrogen-potassium ATPase enzyme (proton pump) found in the stomach lining.

By reducing acid production, it helps:

• Relieve heartburn and acid reflux.
• Heal irritation of the esophagus.
• Promote healing of stomach and duodenal ulcers.
• Prevent damage caused by excessive stomach acid.

Because it is a delayed-release medication, it should be swallowed whole to ensure it works properly.
