Zantac Side Effects - Legal Claims for Cancer Caused by NDMA


Zantac's side effects primarily include digestive problems, headaches, and dizziness. But the current Zantac (ranitidine) litigation concerns the drug's cancer-causing ingredient. People who developed cancer after taking the recalled heartburn medicine are suing the drug manufacturers for financial settlements.

The lawsuits are consolidated into a multi-district litigation (MDL). There is a statute of limitations to sue, so victims should consult with an attorney right away.

Many of these side effects are rare. But anyone who is experiencing these side effects is advised to consult with a doctor right away.

2. Does Zantac cause cancer?

The science indicates that Zantac may cause cancer. According to online pharmacy Valisure, ranitidine causes the chemical NDMA to form in the body during digestion. NDMA (N-Nitrosodimethylamine) is a "probable human carcinogen." Currently, scientists use NDMA to cause cancer in lab rats.2

There is a possible link between taking Zantac and the following diseases:

  • Intestinal cancer (including colon or rectal cancer),
  • Bladder cancer,
  • Pancreatic cancer,
  • Liver cancer,
  • Stomach cancer,
  • Esophageal cancer,
  • Leukemia,
  • Non-Hodgkins lymphoma
  • Multiple myeloma, or
  • Prostate cancer (for people diagnosed at age 65 or younger)

Anyone who developed cancer after taking ranitidine may have a legal claim against the manufacturer.

3. Has Zantac been recalled?

The FDA has requested that every pharmaceutical company stop selling its ranitidine products. So the medication is no longer available on the market.3

Patients who relied on Zantac are advised to consult with a doctor. There are other medications that can safely treat their heartburn.

4. What is the current state of the Zantac lawsuits?

People who developed cancer after taking Zantac are suing the drug manufacturers. There are potentially hundreds of thousands of plaintiffs who still have yet to file. All these lawsuits are being consolidated into an MDL (multidistrict litigation).

MDLs are a way to streamline litigation. One judge makes all the pretrial rulings. Eventually, a few of the cases go to trial. And how these bellwether trials turn out sets the stage for negotiations with the remaining plaintiffs.

The Zantac MDL is in the Southern District of Florida (West Palm Beach). The MDL ID number is 2924. The presiding judge is US District Judge Robin L. Rosenberg. The drug manufacturers being sued include:

A final settlement is not expected for at least another two years.

Note that MDLs are not class actions. Unlike in class actions, MDLs keep every plaintiff's case separate. And each MDL plaintiff gets a different settlement based on the unique facts of his or her case.

5. Is there still time to sue for getting cancer from Zantac?

Most likely yes. But the statute of limitations depends on the plaintiff's location.

In most states, victims have one or two years after getting diagnosed to sue. For victims diagnosed prior to the Zantac recall, the clock began running in 2019.

Zantac victims should consult with a lawyer right away. An attorney can evaluate their case and whether they are still within the time limit to sue.
