Zantac - Consumer Justice Foundation

People experiencing heartburn, acid indigestion or gastroesophageal reflux disease (GERD) who take Zantac or ranitidine products to relieve their symptoms may be at risk for cancer from exposure to N-nitrosodimethylamine (NDMA), a known human carcinogen.

Zantac, the popular heartburn drug used by millions of people across the country, has been at the center of a number of lawsuits filed after testing found that Zantac contains a carcinogenic chemical known as NDMA (N-nitrosodimethylamine) at levels over 3,000 times higher than the FDA-approved amount of NDMA that can be ingested safely. Several recalls have been issued since the presence of NDMA in the drugs was first discovered, including recalls by a number of generic ranitidine makers and by Sanofi, the makers of brand-name Zantac. If you or someone you love took Zantac or another ranitidine-based heartburn drug and subsequently developed cancer of the bladder, stomach, colon or kidney, contact our consumer advocates at Consumer Justice Foundation today. You may be eligible to file a Zantac cancer lawsuit and our consumer advocates can help put you in touch with a knowledgeable drug injury lawyer you can trust.

Zantac Alternatives for Heartburn, Acid Reflux

Amid increasing concerns about the potential for Zantac treatment to cause cancer, more and more people taking prescription or over-the-counter (OTC) Zantac are looking for safer alternatives to the drug. The following are some natural remedies that can help relieve heartburn, acid reflux and other similar issues caused by too much acid in the stomach:

  • Identifying and avoiding foods that trigger symptoms
  • Losing weight around the abdomen
  • Improving digestion
  • Healing inflamed gastric tissues
  • Minimizing stress
  • Consuming gingerroot
  • Eating several small meals instead of fewer large ones
  • Chewing gum
  • Occasional use of baking soda to neutralize acidity

What is Zantac?

A popular heartburn medication available both in prescription form and over the counter that may contain unsafe levels of a cancer-causing chemical known as NDMA possibly leading to stomach cancer, bladder cancer or other cancers.

Zantac (ranitidine) is a histamine-2 (H2) blocker used to decrease the amount of acid in the stomach, which can help relieve the symptoms of conditions like heartburn, acid reflux, acid indigestion, sour stomach, gastric and duodenal ulcers, gastroesophageal reflux disease (GERD) and Barrett’s esophagus. Zantac has been on the market in the United States since the early 1980’s and the brand-name and generic versions of the drug are routinely used by millions of people across the country. Over-the-counter ranitidine is approved to prevent and relieve heartburn associated with acid indigestion and sour stomach and prescription ranitidine is approved for the treatment and prevention of ulcers in the stomach and intestines and the treatment of GERD.

Possible Side Effects Leading to a Zantac Lawsuit

NDMA is a chemical that was once used to make rocket fuel. Today, NDMA is only produced in the United States for use as a research chemical, though it can also occur in the environment as a by-product of certain industrial processes and water disinfection. Based on results from laboratory tests, NDMA, which belongs to a family of chemicals known as N-nitrosamines, has been classified as a probable human carcinogen, meaning it could cause cancer in humans. Among the potential side effects of Zantac use are:

  • Bladder cancer
  • Stomach or gastric cancer
  • Kidney cancer
  • Colon or intestinal cancer
  • Pancreatic cancer

In addition to potentially causing cancer, NDMA is a hepatotoxin. With short-term exposure, NDMA can damage the liver, possibly leading to liver fibrosis and scarring. Long-term exposure to NDMA can increase the risk of liver, lung and kidney tumors.

Link Between Zantac and Cancer

The potential risk of cancer from NDMA exposure is linked to ranitidine, Zantac’s active ingredient. Although the FDA has stated that some recalled ranitidine medications were found to contain NDMA at “low” levels, these levels were actually between 3,000 and 30,000 times higher than the limit federal regulators consider “safe.” Additionally, while the FDA has suggested that the NDMA found in ranitidine samples is an “impurity,” which implies that the Zantac tablets were contaminated with the carcinogen during some part of the manufacturing process, there is growing evidence suggesting that ranitidine metabolizes into NDMA when ingested, meaning the risk appears to be in the drug itself. In fact, during the period that Sanofi and Boehringer Ingelheim were manufacturing and marketing Zantac for heartburn relief, scientific research demonstrated, among other things, that when ranitidine comes in contact with water, it sets off a chemical reaction that can result in the formation of NDMA, and that people who consume ranitidine have a 400-fold increase of NDMA concentration in their urine.

Prior to the Zantac/NDMA controversy, the FDA was investigating the presence of NDMA and other potentially harmful nitrosamine impurities in generic valsartan, losartan and irbesartan medications commonly used to treat blood pressure and heart failure. In the case of the valsartan cancer link, the FDA recommended numerous recalls after Valisure, an online pharmacy that regularly tests the drugs it sells, uncovered potentially dangerous levels of NDMA and other cancer-causing chemicals in the medications. Upon testing its ranitidine pills, Valisure found levels of NDMA in excess of 3,000,000 ng per tablet, more than 30,000 times the FDA’s established daily intake limit of 96 ng. As a result of the potential risk of cancer from NDMA exposure, ranitidine and Zantac have been recalled by several manufacturing companies, including the makers of brand-name Zantac, and a number of pharmacies, including Walgreens, CVS and Walmart, have stopped selling generic ranitidine and brand-name Zantac.

Why We Think Sanofi and Boehringer Ingelheim Should Be Held Liable for Zantac Side Effects

Since Zantac was first approved by the FDA in the 1980’s, there have been numerous studies showing a potential link between ranitidine intake and cancer, including research indicating that ranitidine, when it comes into contact with water, can produce a chemical reaction that results in the formation of NDMA. Despite the fact that this research has been widely available, Sanofi-Aventis and Boehringer Ingelheim, the companies that previously held rights to Zantac, did not issue any warnings to consumers or healthcare professionals about the potential for Zantac to contain a cancer-causing chemical. Plaintiffs involved in the growing Zantac litigation are accusing the drug makers of:

  • Manufacturing a defective and dangerous medication
  • Marketing and selling a product they knew or should have known was contaminated with a chemical known to cause cancer
  • Deliberately choosing not to disclose the potential risk of cancer from Zantac use to consumers or the medical community
  • Knowingly putting patient health at risk
  • Putting profits above patient safety
  • Violating consumer protection laws

What should you do? If you have been diagnosed with bladder cancer, stomach cancer or another serious side effect, you should contact a lawyer as soon as possible to discuss filing a Zantac injury lawsuit.

Millions of people have taken Zantac and generic ranitidine to relieve heartburn, acid reflux and other similar issues, unaware that the makeup of ranitidine-based medications may put them at risk for cancer due to NDMA exposure. With countless people now suffering from bladder cancer, stomach cancer and other forms of cancer after taking Zantac, many are pursuing legal action against Sanofi and Boehringer Ingelheim, filing lawsuits to hold the drug makers accountable for their alleged negligence, their reckless disregard for human health and their willingness to put profits over people. If you took Zantac and developed cancer, you may have grounds to file a Zantac lawsuit against Sanofi and Boehringer Ingelheim in order to pursue the financial compensation you deserve for past and future medical expenses, lost wages, pain and suffering, loss of future earning capacity, loss of enjoyment of life and other damages.
