Ranitidine tablet used for?

What is ranitidine used for?

Ranitidine tablets (brand names included Ranitidine/Zantac in many markets) are used to reduce stomach acid. Doctors commonly prescribe ranitidine for conditions caused by excess acid, including:[1]

- Heartburn and acid indigestion (symptoms of gastroesophageal reflux disease, GERD)
- GERD (reflux that irritates the food pipe/esophagus)
- Stomach and duodenal ulcers (including prevention in some patients)
- Inflammation/irritation of the esophagus caused by acid (esophagitis)
- Zollinger-Ellison syndrome (a rare condition that causes the stomach to produce too much acid)

How does ranitidine work?

Ranitidine blocks histamine (H2) receptors in the stomach lining. That lowers acid production, which helps relieve pain/burning from reflux and ulcers and allows irritated tissue to heal.[1]

What can I use it for if I have heartburn?

For heartburn or acid indigestion symptoms, ranitidine is generally used to reduce acid and ease burning related to reflux.[1]

How fast does it work?

The onset depends on the dose and the person, but H2 blockers like ranitidine typically help within about an hour for many people. If symptoms are frequent or severe, clinicians often check whether another treatment (or a different medication approach) is needed.[1]

Important note: ranitidine availability and safety concerns

Many countries pulled ranitidine products from the market due to concerns about NDMA contamination (a potentially harmful impurity). This can affect whether ranitidine is available in your country and what alternatives are recommended.[1]
