Zantac causes cancer.

That tragic fact is accepted by scientists, lawyers, the FDA, and even Zantac’s manufacturer acknowledges it may be true. If you or your family member were diagnosed with any one of the cancers shown below after taking Zantac regularly, then the Clauson Law Firm wants to get you the compensation you deserve:

  • Breast Cancer
  • Esophageal/Nasal/Throat Cancer
  • Testicular Cancer
  • Lung Cancer (for non-smokers)
  • Bladder Cancer
  • Ovarian Cancer
  • Thyroid Cancer
  • Pancreatic Cancer
  • Kidney Cancer
  • Stomach Cancer
  • Melanoma (including skin cancer)
  • Colorectal
  • Prostate Cancer
  • Brain Cancer
  • Uterine Cancer
  • Non-Hodgkin’s Lymphoma
  • Intestinal Cancer
  • Multiple myeloma
  • Liver Cancer

All these cancers can develop after repeated exposure to Zantac’s main ingredient, ranitadine. Ranitidine is a drug that produces a substance called NDMA when metabolized in the human digestive system. NDMA is a known carcinogen.

Non-cancerous liver damage and serious liver disease can also result from exposure to NDMA.

How Much NDMA is dangerous?

The FDA recommends that no person consume more than 96 nanograms in a day. (A nanogram = one billionth of one gram.) One over-the-counter tablet of Zantac contained more than 2.5 million nanograms! That means one Zantac tablet contained more than 26,040 times the amount of NDMA deemed safe by the FDA!

How dangerous is the NDMA created by Zantac?

Cancer researchers use NDMA to create cancer in laboratory animals so they can study possible cancer cures.

If you or a family member suffered any serious liver damage or were diagnosed with cancer after taking Zantac on any kind of regular basis, you must act now to preserve your rights to recover just compensation for the illness inflicted on you and your family by Zantac’s makers, the Sanofi Corporation and other Zantac makers.

19,671 North Carolinians Died of Cancer in 2018

We lost almost 20,000 of our North Carolina neighbors and friends to cancer in 2018. Only one year earlier, 41,779 new cancer cases were reported in our state.

The American Cancer Society estimates that North Carolina had 55,130 new cancers diagnosed in 2018 alone.

How much Zantac was consumed by those people? Was Zantac a significant contributing factor to their cancer’s development?

If you suspect that a family member you lost to cancer was a Zantac user, either by prescription or over the counter, call the Clauson Law Firm right away. We will analyze the facts to find out if there is a sufficient connection to support a Zantac-related cancer claim.

Who’s Responsible for Zantac Making You Sick?

Four companies are the central targets of negligence claims filed by injured consumers who developed cancer after taking Zantac; they are GlaxoSmithKline (GSK), Pfizer, Boehringer Ingelheim Pharmaceuticals, and Sanofi SA.

GlaxoSmithKline (GSK), a British multinational pharmaceutical company, developed ranitidine in 1976 and began selling it as Zantac in the U.S. in 1983. In 1995, GSK sold the U.S. rights to sell over-the-counter (OTC) Zantac to Pfizer, Inc. The Pfizer company sold Zantac to American consumers until 2006 when it sold its Zantac rights to Boehringer Ingelheim Pharmaceuticals. Finally, in 2017, Boehringer Ingelheim sold its Zantac rights to Sanofi SA.

Cancer Danger Was Known to All These Companies Since the 1980s

GlaxoSmithKline was notified back in 1981 that the ranitidine in Zantac could mix with digestive bacteria and stomach acids, thus producing NDMA, causing cancer. The information was provided by scientists in Italy who had performed extensive research into how ranitidine was metabolized in the human body.

Despite being put on notice of Zantac’s potential cancer risk in 1981, GSK failed to fully disclose the significance of the Italian study to the FDA. GSK marketed the drug so aggressively and on such a wide scale that, by 1988, Zantac had become the bestselling drug in the world, earning over $1 billion in annual sales.

When the topic was finally raised during Zantac’s commercial life, GSK assured the FDA that Zantac was limited to short-term use. Since people would only use the drug for a short period, no toxic buildup would occur. Then, GSK started marketing the drug for long-term use to physicians and healthcare providers around the world. They knew long-term use would pose a cancer risk. They boasted falsely that the drug was safe and sold it anyway. Tens of thousands of cancers may have developed in consumers who trusted these Zantac companies.

In 2004 and again in 2016, more scientific studies proved Zantac produced NDMA carcinogens in the body, noting that bladder cancer was one of the most prominent results. But the companies profiting from and marketing Zantac continued to advertise the drug’s safety.


At the Clauson Law Firm, you are not just a client, you are our mission.

Our entire staff of experience lawyers, paralegals, investigators, consultants, and administrators devote our professional lives to seeing that justice is delivered to victims of corporate negligence.

We know the cancer you or your family member developed after taking Zantac impacted everyone in your home, not just the cancer victim. We know how devastating the disease can be when it strikes. Husbands and wives suffer the pain of watching their spouse struggle to stay strong, to undergo radiation and chemotherapy. Young and adult children witness their parents’ lightheartedness vanish; they sense the fear in the household and share the anxiety and stress as every upcoming hospital visit approaches.

Cancer can be a destroyer of whole families. The fact that your cancer developed because a few multibillion-dollar companies valued profits over consumer safety makes your suffering even more scandalous.

How Big Are the “Big Pharma” Companies that Marketed Zantac?

GlaxoSmithKline, Pfizer, Boehringer Ingelheim, and Sanofi remain among the biggest pharmaceutical corporations on earth. How big are they? Each of the companies that made and sold Zantac earn massive amounts of money from selling drug products to consumers. Now we know that one of those drugs might be responsible for thousands of cancers and deaths.

Their big profits now lead them to big responsibility for all of the suffering Zantac caused.

2019 Revenue for Zantac Companies


Pfizer$51.75 Billion$ 51,750,000,000
GlaxoSmithKline$43.54 Billion$ 43,540,000,000
Boehringer Ingelheim$18.99 Billion$ 18,990,000,000
Sanofi$27.77 Billion$ 27,770,000,000
2019 TOTAL SALES$142.05 Billion$ 142,050,000,000.00


Until Zantac was recalled by the FDA in September 2019, the heartburn pill generated billions of dollars into the corporation’s pockets. These companies reaped profits for years from Zantac sales while you and people like you acquired cancers that their product might have caused.

How Will Your Claim Proceed? (Mass Tort & Multidistrict Litigation)

Tens of thousands of plaintiffs are expected to demand compensation from Zantac’s manufacturers after developing cancer from the product. Lawsuits against the companies are likely to be filed in federal courts across the U.S.

Instead of hundreds of federal judges conducting thousands of hearings about Zantac and its cancer causing properties, with every case involving the same corporate defendants, the multidistrict litigation (MDL) plan provides for a large group of lawsuits to be consolidated into what we call a “mass tort” case and will be assigned to a single federal judge in a single designated federal district.

Zantac Multi-District Litigation Is Now Assigned to Federal Judge Robin Rosenberg

On February 6, 2020, the U.S. Judicial Panel on Multidistrict Litigation (MDL) ordered the Zantac lawsuits transferred Federal Judge Robin Rosenberg, of the Southern District of Florida. So far, the judge has been assigned 230 cases, all involving people who filed claims alleging Zantac caused their cancer.

Let our team of legal experts at Clauson Law represent your Zantac-cancer claim to the federal court and demand that the Zantac-cancer corporate defendants pay you and your family the maximum compensation the law permits.

Why Does One Federal Court Handle All Cases?

The benefit of keeping thousands of claims organized into a single multidistrict litigation (MDL) before a single federal judge is in the saving of many valuable resources and the efficient progress of the entire matter.

Instead of having every individual plaintiff’s lawyer file separate requests for all of the drug makers’ internal records and all of their private emails, all plaintiffs’ pretrial issues are managed by a team of lawyers assigned to the task by the judge. They will share the documents with all other plaintiffs’ lawyers and we will join each other in important legal motions, and move through the court system at the same steady pace.

Hearings will be conducted on issues shared among large groups of victims. No victim’s case will be left behind due to delays or foot-dragging by corporate defense lawyers.

And most importantly, the several drug companies who are responsible for causing every plaintiff’s cancer will be required to provide billions of dollars in a fund to be distributed to each plaintiff in proportion to that victim’s personal circumstances.
