Millions of people suffer occasional or chronic heartburn. Many of them turn to over-the-counter (OTC) or prescription drugs, including Zantac. Zantac is a brand name for generic Ranitidine, a medication that decreases stomach acid production.

Zantac (Ranitidine) belongs to a class of drugs called histamine H2-receptor antagonists, or H2 blockers, which decrease the amount of acid produced by the stomach. Zantac (Ranitidine) is available over the counter and by prescription. First discovered in 1976 and commercially available in 1981, Zantac and other Ranitidine products have been prescribed millions of times and were one of the most commonly prescribed drugs in the United States.

Uses of Zantac

Zantac and ranitidine medications have many uses, primarily focused on stomach conditions. Consumers used over-the-counter (OTC) Zantac for conditions such as:

  • heartburn
  • acid indigestion
  • acid reflux
  • sour stomach

Prescription-strength Zantac is commonly used to:

  • Treat and prevent peptic ulcers in the stomach and intestines.
  • Treat  gastroesophageal reflux disease, also known as GERD.

Zantac Heartburn Medication Discovered to Contain NDMA

In 2019, some Ranitidine products were discovered by the U.S. Food and Drug Administration (FDA) to contain unacceptable levels of N-nitrosodimethylamine (NDMA), which is a carcinogen. In April 2020, Zantac and other ranitidine medications were taken off the market in the United States, Europe, and Australia.

If you or a loved one have taken Zantac (Ranitidine) and been diagnosed with cancer, you may be entitled to compensation.

What is NDMA?

NDMA is short for N-nitrosodimethylamine, a chemical substance that is known to be dangerous. Although NDMA forms in both natural and industrial processes, the United States Environmental Protection Agency (EPA) classifies the chemical as a pollutant and environmental contaminant. NDMA can be a byproduct of gasoline refining, pesticide manufacturing, wastewater treatment, and water chlorination. According to studies of laboratory animals, NDMA is considered to be both hazardous to the liver (hepatotoxic) and damaging to the genetic information contained in a cell (genotoxic).

Does Using Zantac Increase Your Cancer Risk?

Unfortunately, studies have demonstrated a link between the probable human carcinogen N-nitrosodimethylamine (NDMA) in Zantac (Ranitidine) and an increased risk of cancer. Similar types of NDMA exposure have been linked to various cancers, including:

  • stomach cancer
  • small Intestine cancer
  • colorectal cancer
  • esophageal cancer
  • liver cancer
  • bladder cancer
  • prostate cancer
  • pancreatic cancer
  • leukemia
  • non-Hodgkin lymphoma
  • multiple myeloma
  • kidney cancer

Zantac Recalls and Lawsuits

In September 2019, the U.S. Food and Drug Administration (FDA) issued a public safety warning about possible cancer risks from NDMA exposure due to Zantac (Ranitidine). Other countries followed suit, including Canada, the United Kingdom, and others. These warnings were swiftly followed by recalls in the U.S. and around the world. Drug manufacturer Novartis said it would halt distribution of all ranitidine medications made by Sandoz.

In October 2019, CNN reported that drugmaker Sanofi had issued a voluntary recall of Zantac OTC. According to the report, Sanofi is working with the United States Food and Drug Administration to “determine the extent of the recall.” Pharmacy retailers Walmart, Walgreens, and CVS also announced that they were halting the sales of all ranitidine medications over the concerns about the presence of NDMA and negative side effects. 

In September 2019, a class-action lawsuit was filed against Boehringer Ingelheim and Sanofi in the U.S. District Court of Northern California, alleging that the companies hid the risks of side effects from the use of  Zantac, which contains  the active ingredient ranitidine. The lawsuit alleges that Zantac contained high levels of NDMA — more than 26,000 times the amount the FDA has said can be ingested safely on a daily basis. The lawsuit alleges that these pharmaceutical companies violated state consumer protection laws by failing to disclose the presence of NDMA, which the FDA has said is a “probable” cancer-causing chemical.
