In September 2019, the FDA warned that the popular heartburn drug Zantac may contain cancer-causing impurities. These same chemicals have been linked to an increased risk of colorectal cancer, stomach cancer, liver cancer and other health problems.

STATUS OF ZANTAC LAWSUITS: Lawyers are investigating whether individuals diagnosed with cancer in recent years may be entitled to financial compensation through a Zantac lawsuit as a result of the manufacturers’ failure to disclose the presence of these carcinogenic impurities.


MANUFACTURER: Sanofi-Aventis and other generic drug makers

OVERVIEW: Zantac (ranitidine) was first approved by the FDA in 1983, and is used to treat heartburn with acid indigestion, as well as stomach ulcers, gastroesophageal reflux disease (GERD) and other stomach acid production problems. The brand has been owned by a number of different drug manufacturers, including the original developer, GlaxoSmithKline, and later Boehringer Ingelheim, and its current manufacturer, Sanofi-Aventis.

Zantac belongs to a class of heartburn drugs known as H2-receptor antagonists, which decrease acid levels in the stomach. However, it now appears that versions of the drug have been distributed for years with cancer-causing impurities that may be a byproduct of the drug manufacturing process.


In September 2019, the FDA issued a warning about the potential cancer risk from Zantac, indicating that the drug pharmacy Valisure detected high levels of N-nitrosodimethylamine (NDMA) in pills. This chemical has been linked to a risk of cancer among humans, raising serious concerns about the safety of Zantac.

Using the same detection methods as the FDA, Valisure found 2,511,469 nanograms (ng) of NDMA per 150 mg tablet of Zantac. The FDA’s permissible intake limit is 96 ng per day, which means the Zantac tablets contained 26,000 times that.

The FDA has since said the technique used temperatures that were too high, resulting in excessive NDMA detection. However, the FDA also said its own testing still resulted in unacceptable levels of NDMA from Zantac.

Since the FDA issued the warning, most major pharmacy chains have pulled Zantac from shelves and several generic manufacturers have either issued Zantac recalls or have halted distribution.

Zantac was the first drug to ever become a “blockbuster” when it broke $1 billion in sales in 1986. In 2018, Zantac was still one of the top 10 heartburn tablets sold in the U.S.

FIND OUT IF YOU MAY QUALIFY FOR A ZANTAC CANCER LAWSUIT: As a result of the drug manufacturers’ failure to adequately ensure the purity of their products or warn about the risks associated with their medications, Zantac injury lawyers are evaluating whether users may be entitled to compensation through an individual claim or class action lawsuits due to the risk of various cancers, including:

  • Liver Cancer
  • Kidney Cancer
  • Stomach Cancer
  • Colorectal Cancer
  • Prostate Cancer
  • Esophageal Cancer
  • Pancreatic Cancer
  • Bladder Cancer
  • Other Digestive Tract Cancers
