Zantac Recall

On Sept. 13, 2019, the Food and Drug Administration (FDA) first issued a warning about medicines containing ranitidine. Ranitidine, the active ingredient in the heartburn drug Zantac and its generics, was found to cause NDMA to form in the body after ingestion. NDMA is classified as a probable human carcinogen.

On April 2, 2020, the Food and Drug Administration (FDA) recommended removing all prescription and over-the-counter versions of ranitidine, including Zantac and its generics, from store shelves.

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, companies recalled numerous ranitidine products in the U.S.

Furthermore, the older a ranitidine product is, or the longer it sat on store shelves or in 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. Exposure to higher temperatures also increases levels of NDMA in the medication.

Ingesting NDMA in low levels isn’t thought to increase the risk of cancer, 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.

What is Zantac (Ranitidine)?

Ranitidine is an H2 (histamine-2) blocker, which decreases the amount of acid created by the stomach. The FDA approved over-the-counter ranitidine to prevent and relieve heartburn associated with acid indigestion and sour stomach. Prescription ranitidine received approval 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 the U.S. banned Zantac, 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)

Who makes Zantac?

Zantac was originally made by Pfizer from 2000 to 2006. Sanofi, another pharmaceutical company, is the current maker of Zantac. Many other companies produce the drug under its generic name: Ranitidine.

What is NDMA?

NDMA (N-nitrosodimethylamine) is a known environmental contaminant. The compound is present 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

NDMA has been found in laboratory research to induce tumors in experimental animals, according to the U.S. National Library of Medicine. In various species, exposure to NDMA has caused tumors primarily in the liver, respiratory tract, kidney, and blood vessels.

Some cancers related to NDMA include the stomach, small intestine, bladder, kidney, colorectal, esophageal, prostate, pancreatic, leukemia, non-Hodgkin’s lymphoma, and multiple myeloma.

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.

However, at this point, scientists have published no studies 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.

The FDA considers consuming up to 96 nanograms of NDMA per day 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. Valisure 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: LC-HRMS and LC-MS/MS. The agency also developed a simulated gastric fluid (SGF) model for use with LC-MS testing to estimate the biological significance of in-vitro findings. Simulated gastric fluid and simulated intestinal fluid models detect the formation of NDMA in systems that approximate the stomach and intestinal fluids.

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

Scientists have found NDMA 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, experts have published no studies 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 Multidistrict Litigation

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 consumers would register thousands more lawsuits in the MDL in the coming months.

Zantac lawsuits claim that Zantac makers Sanofi and Boehringer Ingelheim, knew–or should have known–a cancer causing impurity was present in their products. 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.
