Zantac Ranitidine Lawsuit - Legal Claims for Cancer Caused by NDMA


A Zantac lawsuit is a legal claim for financial compensation by people who contracted cancer from taking the heartburn medication. Plaintiffs allege that drug manufacturers failed to warn them that Zantac (ranitidine) contains the carcinogen NDMA. This is the same substance believed to have caused cancer in consumers of the blood pressure medications Valsartan and Losartan.

On April 1, 2020, the Food and Drug Administration (FDA) requested that all manufacturers withdraw their Zantac and ranitidine products immediately. A few months prior, the FDA announced it found "unacceptable amounts" of NDMA in ranitidine. Since then, more than a dozen pharmaceutical companies have recalled the drug.

Shouse Law Group is helping Zantac victims throughout the United States sue the drug manufacturers. We are fighting to collect money damages to cover their doctor's bills, lost earnings, and pain and suffering.

Our ranitidine lawsuits are not part of a class action. Instead, they are individual lawsuits of the victim against the manufacturer. The claims will be consolidated into a Zantac multidistrict litigation (MDL). This will expedite the settlement process.

We are accepting clients who developed any of the following diseases after taking Zantac or its generic ranitidine:

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

There is a short statute of limitations to file suit. So be sure to consult with an attorney soon.

In this article, our Zantac lawyers discuss:

Zantac users who developed cancer may have legal grounds to sue.

1. What are the grounds for a Zantac lawsuit?

Two claims victims can sue drug manufacturers for are:

  1. The drug had a defective design, and
  2. The drug's labeling failed to warn about its risks

1.1 Defective design

Courts hold ranitidine manufacturers to a strict liability standard. Therefore, drug makers are responsible if:

  1. The drug's defective design posed a foreseeable risk, and
  2. The drug was manufactured and used as it was supposed to be1

According to online pharmacy Valisure, ranitidine molecules are inherently unstable. When a person ingests a normal dosage, it converts into the carcinogen NDMA (N-nitrosodimethylamine). In short, NDMA is a natural by-product of ranitidine's ingredients.2

Therefore, it does not matter which pharmaceutical company manufactured the drug. By design, Zantac reacts with the body's chemistry to create NDMA. Therefore, all lots of Zantac are potentially cancer-causing.

Common evidence of design defects includes the original Zantac formula. Plaintiffs' attorneys will also rely on expert witnesses to testify about the design problems.

1.2 Improper labeling and failure to warn

Like all medications, Zantac has a warning label. But its label omits any mention of its carcinogenic risks.

Had physicians been informed of the risks, they may not have recommended or prescribed Zantac. And had patients known of the risks, they may have elected against taking it.

The best evidence of failure to warn is the Zantac packaging itself. Its omission of NDMA-related information suggests consumers were not fully informed of the dangers.

(In some states, brand name drug manufacturers have a legal duty to warn users of generic versions they do not make. In other states, these manufacturers do not have a duty to warn. So which state the victim sues in will dictate how to craft the lawsuit.)3

2. What is the evidence that Zantac causes cancer?

According to online pharmacy Valisure, ranitidine's inherent instability causes a chemical reaction that produces high levels of NDMA in the digestive tract. This is particularly true when nitrates are present.

The FDA disagrees. It claims that typical stomach conditions should not cause ranitidine to metabolize into NDMA. Instead, the FDA maintains that NDMA is an impurity found in the drug itself. But on April 1, 2020, it also admitted that storing ranitidine at higher than room temperature "may result in consumer exposure to unacceptable levels of this impurity."4

Either way, the US Environmental Protection Agency (EPA) classifies NDMA as a “probable human carcinogen." In other words, it probably causes cancer in people. Currently, research scientists use NDMA to cause cancer in lab rats.5

NDMA is safe in humans if limited to 96 nanograms per day.6 But one Zantac tablet contains about 2.5 to 3 million nanograms. That is 26,000 to 31,000 times the recommended daily maximum.7 And studies show that people who take Zantac have a 400-fold increase of NDMA in their urine.8

Plaintiffs in a Zantac lawsuit need proof they took the drug. Frequent usage over a sustained period of time strengthens their case. Helpful evidence includes:

  • Pharmacy records (if the Zantac was prescribed),
  • Receipts,
  • Pill bottles/ packaging, and
  • Medical records that show the plaintiff developed cancer after taking Zantac

It may be challenging for OTC (over the counter) users to show proof of Zantac usage. Most people do not keep their receipts or pill bottles. But the following records could help:

  • Rx prescription drug cards,
  • Health flexible spending accounts (FSA),
  • Health saving accounts (HSA),
  • Health reimbursement accounts (HRA), and/or
  • Affidavits or declarations by the victim that he/she took OTC Zantac

The FDA found high levels of NDMA in many ranitidine products. This led to mass recalls.

3. Is this a class action or individual lawsuits?

Individual lawsuits. But every Zantac lawsuit will eventually be joined into an MDL -- short for "multi-district litigation." MDLs are a way for courts to streamline pretrial proceedings. Eventually, the MDL judge will permit a handful of cases to proceed to trial. The results of these bellwether trials set the tone for future negotiations.

Currently, there is an MDL out of the Southern District of Florida (West Palm Beach). The MDL number is 2924. The judge is US District Judge Robin L. Rosenberg. The defendants include:

MDLs are fundamentally different from class actions. In MDLs, every case remains separate. In class actions, they are all combined.

There currently are some pending class actions against ranitidine manufacturers. But they are geared for people who bought ranitidine but have not gotten sick. These plaintiffs simply want their money back. They would not have bought the ranitidine had they known of the risks.9

4. Has Zantac been recalled?

On April 1, 2020, the FDA requested that all Zantac and ranitidine manufacturers withdraw the drug. This follows a warning the FDA issued on September 13, 2019. In the interim, more than a dozen manufacturers have voluntarily recalled their ranitidine products:

The FDA also asked manufacturers to do their own laboratory tests on all their ranitidine products and to mail the FDA samples. The FDA further instructed manufacturers not to sell any lots that show more than the daily NDMA limit of 96 nanograms. And manufacturers must notify the FDA if any lots do exceed the NDMA limit.

The following are some of the retailers that stopped selling ranitidine:

  • CVS,
  • Walmart,
  • Walgreens, and
  • Rite Aid

Alternatives to Zantac that do not contain NDMA include: 

  • Pepcid (famotidine),
  • Tagamet (cimetidine),
  • Nexium (esomeprazole),
  • Prevacid (lansoprazole), and
  • Prilosec (omeprazole)

5. Have Zantac lawyers made any settlements yet?

No. Settlement talks typically do not begin until some cases go to trial. How these bellwether trials turn out helps gauge what money victims can demand. Predictably, plaintiffs attorneys are aiming very high. No amount of millions can make up for getting cancer.

MDL settlements typically resolve through either:

  1. Global (or matrix) settlements: Defendants pay out a sum that covers all claims. And plaintiffs' attorneys use a matrix of criteria to determine how much each plaintiff receives; or
  2. Inventory settlements: Each plaintiff agrees to an acceptable minimum amount. And if their attorneys win a larger amount, each client will receive a percentage of the bonus funds.

6. Who makes Zantac?

More than 10 manufacturers make prescription Zantac. And more than 20 make OTC Zantac. Manufacturers that have recalled its ranitidine products include:

GSK originally developed prescription ranitidine in 1977. It was FDA-approved in 1983 and went generic the following year. It helps prevent and treat:

  • Heartburn,
  • GERD (gastroesophageal reflux disease),
  • Ulcers,
  • Acid reflux, and
  • Sour stomach

Pfizer developed OTC ranitidine in 2004. Boehringer Ingelheim purchased it in 2006. Then Sanofi purchased it in 2017.

Ranitidine is available in various forms, including capsules, tablets, and syrup. Common dosages include 75 mg, 150 mg, and 300 mg.

Ranitidine was one of the first drugs to bring in a billion dollars in sales.10
