Why is Zantac prescribed?
Zantac is used to decrease the production of stomach acid, which may reduce irritation to the stomach lining and help heal ulcers and other gastrointestinal conditions. It's prescribed for the following:
Short-term treatment (4 to 8 weeks) of active ulcers, specifically duodenal ulcers or benign stomach ulcers (also called gastric ulcers).
Maintenance therapy (at a reduced dosage) to help keep the ulcer from coming back after it has healed.
Treatment of conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome and systemic mastocytosis.
Treatment of gastroesophageal reflux disease (also known as GERD, which occurs when stomach acid backs up into the esophagus).
Treating and maintaining healing of erosive esophagitis (severe inflammation of the esophagus).
Two over-the-counter versions, Zantac 75 and Zantac 150, are also available for relieving and preventing heartburn, acid indigestion, and sour stomach. However, the prescription version is still needed for treatment of ulcers, esophagitis, GERD, and other conditions that require monitoring by a doctor.
