What is Zantac?

Zantac, or ranitidine, was once the world’s top-selling drug. It is available either by prescription or over the counter. In Sept. 2019, the FDA began investigating whether Zantac causes carcinogens to form in its users. It is suspected that Zantac causes levels of the probable carcinogen N-nitrosodimethylamine (NDMA) to rise when ingested by users.

FDA Discovers Carcinogen in Zantac

The U.S. FDA reported on September 13, 2019 that it had discovered the carcinogenic contaminant N-nitrosodimethylamine (NDMA) in Zantac (ranitidine).

The FDA advisory stated that the level of contamination is “low”; however, the levels the agency called low have been found to be between 3,000 and 26,000 times higher than what the FDA had determined to be “safe.”

The first Zantac lawsuit was filed in California on the same day the FDA issued its advisory. Plaintiffs in Zantac lawsuits accuse drug makers Sanofi and Boerhringer Ingelheim of making, marketing, and selling a product they knew or should have known had been contaminated with an industrial chemical known to cause cancer.

Investigating the Cause of NDMA Contamination

The exact cause of the NDMA contamination is still under investigation. Nevertheless, during the period in which Boerhinger Ingelheim and Sanofi made and marketed Zantac, scientific research showed a clear link between ranitidine – the active ingredient listed in Zantac – and NDMA. The research showed that when ranitidine comes into contact with water, the chemical reaction creates NDMA.


NDMA, Zantac Complications, Symptoms

Besides causing cancer, NDMA is a potent hepatotoxin, a chemical which damages the liver. Even short-term exposure to NDMA can cause liver damage, including liver fibrosis and scarring. Long-term exposure can also increase the risk of liver tumors, kidney tumors, and lung tumors.

NDMA overexposure symptoms include headaches; fever; nausea; jaundice; vomiting; abdominal cramps; enlarged liver; dizziness; and reduced function of the liver, kidneys, lungs.

Adverse effects linked with Zantac include:

  • Cancer
  • Tumors of the liver, kidney, lungs
  • Nervous system disorders
  • Arrhythmia or tachycardia (irregular or rapid heartbeat)
  • Vitamin B-12 deficiency
  • Hepatitis, liver failure, jaundice
  • Increased risk of pneumonia
  • Low platelet levels in the blood
  • Skin rashes and hair loss

NDMA Extremely Hazardous

NDMA is classified as “extremely hazardous,” under the federal Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA). Stringent reporting requirements, therefore, are supposed to guide companies and individuals who produce, store, or use NDMA in large amounts.

  • physical and mental injuries
  • wage loss
  • loss of enjoyment of life
  • punitive damages, if relevant

Zantac Research

Research from Valisure, an online pharmacy, along with that of Stanford University and others, found that NDMA was the result of the “inherent instability” of the ranitidine molecule. This means that all manufacturers, brand or generic, as well as all lots of ranitidine-containing medications, are affected and could generate very high levels of NDMA in the human body.

Zantac cancer link studies include:

  • A 2004 National Cancer Institute study linked Ranitidine (Zantac) to Bladder Cancer. Link.
  • A 2016 Stanford University study gave 10 healthy volunteers 150 milligrams of Zantac and found that subsequent NDMA levels in their urine exceeded 47,000 nanograms  Link
  • A 2017 study shows why Urination of ranitidine into wastewater is suspected as a source of NDMA in municipal drinking water. Link
