Nizatidine — Uses, Dosage, Side Effects & Safety

Drug class: Histamine H2-receptor antagonist (H2 blocker)

Overview

Nizatidine is a medication used to treat conditions caused by excess stomach acid, such as ulcers in the stomach and intestines, gastroesophageal reflux disease (GERD), and conditions where the stomach produces too much acid, like Zollinger-Ellison syndrome. It works by blocking histamine H2 receptors in the stomach lining, which reduces the amount of acid produced. This helps relieve symptoms like heartburn, indigestion, and promotes healing of ulcers. Key points for patients: Nizatidine is usually well tolerated, but it should be taken as prescribed. It may take a few days to feel full relief. Do not stop taking it suddenly without consulting your doctor. Always inform your healthcare provider about other medications you are taking.
