Does Ranitidine Cause Cancer?

It has recently been discovered through routine testing that the popular heartburn drug Zantac (ranitidine) contains unsafe levels of the known carcinogen N-nitrosodimethylamine (NDMA). Zantac and similar medications have been on the market since the early 1980s, marketed as a safe and effective treatment for symptoms such as heartburn, acid reflux, peptic ulcers, GERD and indigestion. Though the US Federal Drug Administration (FDA) has not issued an official recall, they ordered all ranitidine manufacturers to conduct testing for NDMA. Additionally, a large number of these companies including the primary manufacturers have voluntarily recalled the products themselves.

The Link between Zantac (Ranitidine) and Cancer

This testing showed that ranitidine actually breaks down in the body to form NDMA due to the instability of its chemical structure, which essentially reacts with itself to degrade into the carcinogen. Additional research shows that ranitidine forms significant amounts of NDMA with nitrates present, which is extremely worrisome as Zantac has been specifically marketed to treat symptoms caused by foods with high nitrate levels.

Ranitidine users who have been diagnosed with cancer are filing lawsuits against these manufacturers on several counts, stating that regular and long-term ranitidine use was the cause of their cancer. These cases assert that the drug companies were responsible for testing products and had a duty to report that the drug contained a carcinogenic substance. If they had known of the possible cancer risks, a large number of consumers would not have purchased ranitidine products. Many people have been using ranitidine for years, even decades, before the recall, and there are still many who are unaware of the dangers. The majority of these users have developed cancers of the stomach, esophagus, and other areas of the GI tract where ranitidine targets, as well as cancers of the blood, bladder, liver, and others.

Cancer Lawsuits and Currently being Filed Against the Manufacturers of Zantac (Ranitidine).

One of the first lawsuits filed was by a California man who ingested 150 mg of ranitidine per day from 2010 - 2019 and was diagnosed with colorectal cancer in 2017. He first heard about the link between Zantac and cancer early October 2019, when he listened to a podcast discussing high levels of NDMA in the drug. Another case involves a woman in New Jersey who developed esophageal cancer after taking at least one 75 mg dosage of Zantac per day for several years.

What Types of Cancers are being Linked to using Zantac?

Zantac may be tied to various types of cancers, since the formation of NDMA following the ingestion of Zantac (Ranitidine) may occur throughout different areas of the body.

Users who have either taken or are currently taking Zantac and have been diagnosed with any of the following cancers may be eligible to receive compensation:

  • Stomach cancer

  • Liver cancer

  • Esophageal/colorectal cancer

  • Bladder cancer

  • Kidney/renal cancer

  • Leukemia

  • Multiple Myeloma

  • Non-Hodgkin's Lymphoma

  • Pancreatic cancer

  • Prostate cancer

  • Small intestine cancer
