Zantac (Ranitidine) — Uses, Dosage, Side Effects & Safety

Drug class: Histamine-2 (H2) receptor antagonist

Overview

Zantac (ranitidine) is a medication used to reduce the amount of acid produced in the stomach. It is commonly prescribed for conditions such as gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger-Ellison syndrome. Zantac can also be used to prevent and treat heartburn and indigestion associated with acid reflux. Zantac works by blocking histamine H2 receptors in the stomach lining, which decreases gastric acid secretion. This helps relieve symptoms like heartburn, stomach pain, and discomfort caused by excess acid. Patients should be aware that Zantac has been withdrawn or restricted in several countries due to concerns about impurities (NDMA) found in some ranitidine products. Always consult your healthcare provider before starting or continuing this medication.
