ZANTAC LITIGATION – Claims for Cancer Caused by Using Zantac (Ranitidine)

For a period of time, scientific evidence strongly suggested that the popular heartburn medication Zantac (Ranitidine) caused cancer. The evidence pointed to the presence of the known carcinogen NDMA, which stands for N-Nitrosodimethylamine. It is believed that the active ingredient in Zantac, the ranitidine molecule itself, is unstable and breaks down to NDMA when digested.

The evidence that Zantac is unsafe is so overwhelming that on April 1, 2020, the FDA ordered all Zantac and Ranitidine products off the shelf.

Fuicelli & Lee is actively accepting clients who developed any of the following after taking Zantac or the generic Ranitidine:

  • Stomach Cancer
  • Liver Cancer
  • Bladder Cancer
  • Pancreatic Cancer
  • Leukemia
  • Prostate Cancer
  • Esophageal Cancer; or
  • Non-Hodgkin’s Lymphoma


Generally speaking, claims against the manufacturers of these drugs require proof the drug posed a foreseeable risk and were manufactured and used as intended. Because NDMA is a natural by-product of the body’s reaction to Ranitidine, it likely does not matter which particular pharmaceutical company manufactured the drug. All lots of Zantac, and its generic Ranitidine, potentially cause cancer.

The warning label which accompanies Zantac (and its generic) is devoid of any mention that it likely causes cancer. As such, a legal “Failure to Warn” claim is present. Had doctors known about these risks, they likely would have recommended one of the many other anti-acid drugs which do not contain NDMA; drugs like Pepcid, Nexium, Prevacid, or Prilosec. Likewise, had consumers been fully informed, they likely would have looked elsewhere.


Individuals making claims based on Zantac use need to show they actually took the drug. The longer people took the drug, the greater the risk of harm. Thus, showing use is key; the more proof of use, the stronger the case. Individuals can prove they took the drug in any number of ways including pharmacy records, actual bottles or packaging, medical records, and receipts.


Given that the FDA first issued a warning about Zantac on September 13, 2019, there is likely still time to assert your claim. But please be aware — the clock is ticking!! Please contact us as soon as possible so we can ascertain the statute of limitations that apply in your state and take action quickly if needed.


If you or a loved one has been diagnosed with one of the cancers listed above after taking Zantac, please contact us right away. If we do not collect on your case, you owe nothing.
