Common Uses of Zantac
Zantac was widely used for various conditions related to stomach acid.
-
Heartburn: A burning sensation in the chest and throat caused by stomach acid flowing back up into the esophagus.
-
Gastroesophageal Reflux Disease (GERD): A condition where stomach acid frequently flows back into the esophagus.
-
Peptic Ulcers: Sores that develop on the inside lining of your stomach and the upper portion of your small intestine.
-
Zollinger-Ellison Syndrome: A rare disorder where the stomach produces too much acid due to a tumor in the pancreas or small intestine.
How is Zantac Administered?

- Long-term exposure to NDMA has been linked to various types of cancer, including lung, liver, and stomach cancer.
Historical Popularity of Zantac
Zantac was incredibly popular before its recall.
-
It was the first drug to generate $1 billion in sales.
-
Over 15 million prescriptions were written annually.
Manufacturing Issues

Key Takeaways on Zantac
Zantac, once a go-to for heartburn and acid reflux, has faced significant scrutiny. Introduced in 1976, it was popular for treating conditions like GERD and peptic ulcers. However, concerns arose in 2019 when the FDA found NDMA, a probable carcinogen, in ranitidine products. This led to a global recall and a shift towards safer alternatives like omeprazole and famotidine. Patients should be aware of potential side effects, including headaches, liver damage, and rare skin reactions. If you've taken Zantac and experienced adverse effects, consult your healthcare provider. Legal actions are ongoing for those affected by NDMA contamination.
