Zantac Cancer

Zantac (ranitidine), the popular heartburn medication, has been linked to cancer due to NDMA contamination. If you or a loved one have been diagnosed with cancer and have been a consistent user of Zantac (ranitidine), you may have a claim.

 

Zantac was voluntarily recalled from the market on Sept. 13, 2019, after it was discovered that it contained the probable cancer-causing impurity NDMA. On April 1, 2020, the FDA removed Zantac and all ranitidine products from the market due to health risks.

Zantac Cancer Lawsuits


On April 2, 2020, all prescription and over-the-counter versions of ranitidine, the active ingredient in the heartburn and acid reflux medicine Zantac, and generics were withdrawn from the market because they were contaminated with a probable human carcinogen called N-Nitrosodimethylamine, or NDMA.

Zantac Recalls


On April 2, 2020, the Food and Drug Administration (FDA) recommended removing all prescription and over-the-counter versions of ranitidine, the active ingredient in the heartburn and acid reflux medicine Zantac, as well as generics.

New testing by the agency and an evaluation prompted by information from third-party laboratories confirmed that the probable human carcinogen N-Nitrosodimethylamine, or NDMA, was present in ranitidine and that the levels of NDMA increase even under normal storage conditions and could increase significantly when stored at higher temperatures.

Furthermore, the older a ranitidine product is, or the longer it sat in store shelves or a consumer’s medicine cabinet, the greater the level of NDMA. These conditions could cause the levels of NDMA in ranitidine to rise above the acceptable daily intake limit.

Ingesting NDMA in low levels isn’t thought to increase the risk of cancer, the FDA said. But, sustained higher levels of exposure may increase the risk of cancer in humans.

At least 22 countries, including the United States, Canada, and France, have either removed, stopped sales of, or recalled ranitidine-containing products.

Why was Zantac Recalled?


On Sept. 13, 2019, the Food and Drug Administration (FDA) first warned that some medicines containing ranitidine, the active drug ingredient in the heartburn and acid reflux medicine Zantac and generics, was found to cause NDMA, classified as a probable human carcinogen, to form in the body after ingestion.

The FDA advised companies to recall their ranitidine products if testing showed levels of NDMA above the acceptable daily intake of 96 nanograms per day. In the weeks and months that followed, numerous ranitidine products were recalled in the U.S.

FDA testing later revealed traces of NDMA in nizatidine, a similar acid reducer also known by the brand-name prescription drug Axid.

What is (Zantac) Ranitidine?


Ranitidine is an H2 (histamine-2) blocker, which decreases the amount of acid created by the stomach. Over-the-counter ranitidine is approved to prevent and relieve heartburn associated with acid indigestion and sour stomach. Prescription ranitidine is approved for multiple indications, including the treatment and prevention of ulcers of the stomach and intestines and the treatment of Zollinger-Ellison syndrome and gastroesophageal reflux disease (GERD).

Researchers first raised questions about NDMA in Zantac and its link to cancer decades ago, beginning in the 1980s. There is evidence that Zantac makers Sanofi and Boehringer Ingelheim knew about NDMA in Zantac and its link to cancer but covered up this information.

Before Zantac was banned in the U.S., about 15 million Americans took prescription-strength ranitidine, and millions more regularly took the antacid over the counter to treat heartburn.

Some generic and brand-name products that contain ranitidine include:

  • Zantac 150 mg Tablets
  • Zantac 150 mg Maximum Strength
  • Zantac 150 mg Maximum Strength Cool Mint
  • Zantac 75 mg Tablets
  • Wal-Zan 150 mg
  • Wal-Zan 75 mg
  • Heartburn Relief (ranitidine)
  • Acid Reducer (ranitidine)
  • Acid Control (ranitidine)

What Lot Numbers are Included in the Zantac (Ranitidine) Recall?


Dozens of ranitidine manufacturers have recalled their products due to unacceptable levels of the impurity NDMA, a probable human carcinogen. The FDA continues to test the products and update the list of recalled medicines and lot numbers.

Zantac and Cancer


NDMA has been found in laboratory research to induce tumors in experimental animals, according to the U.S. National Library of Medicine. Some cancers that may be related to NDMA include:

  • Bladder cancer
  • Brain cancer
  • Breast cancer
  • Colorectal cancer
  • Esophageal cancer
  • Kidney cancer
  • Leukemia
  • Liver cancer
  • Lung cancer (non-smokers)
  • Lymphoma
  • Multiple myeloma
  • Non-Hodgkin’s lymphoma
  • Ovarian cancer
  • Pancreatic cancer
  • Small intestine cancer
  • Stomach cancer
  • Testicular cancer
  • Thyroid cancer
  • Uterine cancer
  • Others

However, at this point, no studies have been published that can identify how great the risk of developing cancer is for someone who has used these drugs or the specific tumors it may cause.

What is NDMA?


NDMA (N-nitrosodimethylamine) is a known environmental contaminant. It is found in water and foods, including meats, dairy products, and vegetables. High levels of NDMA exposure may cause liver damage in humans. Overexposure to NDMA can cause the following symptoms:

  • Dizziness
  • Headache
  • Fever
  • Nausea
  • Jaundice
  • Vomiting
  • Abdominal cramps
  • Enlarged liver
  • Reduced function of liver, kidneys, or lungs

In animal studies of various species, exposure to NDMA has caused tumors primarily in the liver, respiratory tract, kidney, and blood vessels.

The U.S. Environmental Protection Agency (EPA) listed NDMA as a B2 (probable human) carcinogen based on the induction of tumors in rodents and nonrodent mammals exposed to NDMA by various routes.

According to the FDA, consuming up to 96 nanograms of NDMA per day is considered reasonably safe for human ingestion based on lifetime exposure. But, the FDA said, sustained higher levels of exposure [to NDMA] may increase cancer risk in humans.

How was NDMA found in Zantac (ranitidine)?


Online pharmacy company Valisure conducted routine testing of ranitidine medications and, upon finding elevated levels of NDMA in ranitidine, first alerted the FDA in June 2019. In September 2019, the company provided detailed information in a citizen petition to the FDA, explaining that it had detected levels of NDMA at three million nanograms per tablet, far more than the agency’s permissible daily intake of 96 nanograms.

Valisure said the NDMA was likely due to an inherent instability of the ranitidine molecule. The ranitidine molecule contains both nitrite and dimethylamine (‘DMA’) groups, which are well known to combine to firm NDMA. The pharmacy called for a recall and suspension of sales of all lots of the products containing ranitidine.

The FDA alerted the public on Sept. 13, 2019. Oct. 2, 2019, the FDA recommended manufacturers use one of two techniques to test their ranitidine products for the presence of NDMA, the LC-HRMS method, and the LC-MS/MS method. The agency also developed a simulated gastric fluid (SGF) model to be used with the LC-MS testing method to estimate the biological significance of in vitro findings. The simulated gastric fluid and simulated intestinal fluid models are intended to detect the formation of NDMA in systems that approximate the stomach and intestinal fluids.

NDMA Cancer


NDMA has been found in laboratory research to induce tumors in experimental animals, according to the U.S. National Library of Medicine. Some cancers related to NDMA include the stomach, small intestine, bladder, kidney, colorectal, esophageal, prostate, pancreatic, leukemia, non-Hodgkin’s lymphoma, and multiple myeloma.

However, at this point, no studies have been published that can identify how great the risk of developing cancer is for someone who has used these drugs or the specific tumors it may cause.

Zantac Lawsuits


On Feb. 6, 2020, the Judicial Panel on Multidistrict Litigation consolidated several Zantac Cancer lawsuits before federal Judge Robin L. Rosenberg in West Palm Beach, Florida. Since then, more than 400 additional lawsuits have been direct-filed or transferred into the Zantac multidistrict litigation (MDL). The court anticipated that thousands of more lawsuits would be registered in the MDL in the coming months.

Zantac lawsuits claim that Zantac makers Sanofi and Boehringer Ingelheim knew or should have known their Zantac products were contaminated with a cancer-causing impurity. Still, they failed to disclose this risk to the federal government. The companies also failed to warn consumers that by consuming the ranitidine products, they were at increased risk of developing various life-threatening cancers.

A separate class-action lawsuit accuses Zantac makers of exposing consumers to unsafe levels of NDMA and seeks compensation for the purchase of prescriptions of Zantac and ranitidine products.
