Rantac 150 mg

Rantac 150 mg is a ranitidine tablet that helps reduce extra stomach acid. It belongs to the H2 blocker class, which means it lowers acid by blocking histamine H2 receptors in the stomach. In simple words, it calms down acid production, so symptoms like heartburn, sour burps, burning in the chest, or acid taste in the mouth feel better. Doctors have also used it for gastritis, gastric and duodenal ulcers, and reflux disease when appropriate.

What Rantac 150 mg Does

• Reduces stomach acid during the day and at night
• Relieves heartburn and acidity symptoms
• Supports ulcer healing and helps prevent ulcer recurrence when prescribed
• Eases irritation from reflux into the food pipe

Composition and Strength

• Excipients common tablet ingredients as used by the manufacturer

Who Can Use It

How To Take Rantac 150 mg

• Swallow the tablet with water. With or without food is usually fine

• Do not crush or chew unless a pharmacist confirms it is okay for your specific tablet
• Do not take more than directed or for longer than advised

How It Works in Simple Terms

Your stomach makes acid with help from histamine signals. Rantac 150 mg blocks those H2 signals, so acid output drops. Less acid means less burning, less irritation, and a better chance for an ulcer or inflamed tissue to heal. It does not numb the pain. It tackles the acid trigger behind the pain.
