Zantac Cancer


For many years, Zantac has been a popular over-the-counter medication used to treat heartburn, acid reflux, and other stomach-related issues. However, recent studies have linked the use of Zantac to an increased risk of cancer. In this article, we will discuss the latest developments surrounding Zantac and its potential cancer-causing properties.

What is Zantac?

Zantac, also known as ranitidine, is a medication that belongs to a class of drugs called H2 blockers. It works by reducing the amount of acid produced in the stomach, which can help alleviate symptoms such as heartburn, acid reflux, and indigestion. Zantac was first approved by the FDA in 1983 and has been available over-the-counter since 1995.

Why is Zantac Linked to Cancer?

In 2019, the FDA announced that it had discovered a possible cancer-causing impurity called N-nitrosodimethylamine (NDMA) in Zantac. NDMA is a known carcinogen that can cause cancer in humans. The levels of NDMA found in Zantac were found to be above the acceptable daily intake levels set by the FDA, leading to concerns about the safety of the medication.

What Types of Cancer are Linked to Zantac?

The use of Zantac has been linked to several types of cancer, including:

  • Stomach cancer
  • Bladder cancer
  • Colon and rectal cancer
  • Esophageal cancer
  • Liver cancer

What Should You Do if You Have Taken Zantac?

If you have taken Zantac, you should speak to your doctor about your concerns. They may recommend that you switch to a different medication or undergo cancer screening tests to monitor for any potential issues. It is important to note that not everyone who takes Zantac will develop cancer, but the risk is higher for those who have taken the medication regularly over a long period of time.

What is Being Done About Zantac?

In response to the discovery of NDMA in Zantac, several companies have issued voluntary recalls of the medication. The FDA has also requested that all manufacturers of ranitidine products, including Zantac, conduct their own testing to ensure that their products do not contain unsafe levels of NDMA. Additionally, several lawsuits have been filed against the makers of Zantac, alleging that they knew about the potential cancer risks associated with the medication but failed to disclose this information to the public.

Alternatives to Zantac

If you are concerned about the potential cancer risks associated with Zantac, there are several alternatives available. These include:

  • Proton pump inhibitors (PPIs), such as omeprazole and esomeprazole
  • Antacids, such as Tums and Rolaids
  • H2 blockers, such as famotidine and cimetidine


Zantac has been a popular medication for many years, but recent studies have linked it to an increased risk of cancer. If you have taken Zantac, it is important to speak to your doctor about your concerns and explore alternative treatment options. As more information becomes available, it is our hope that regulators and manufacturers will take the necessary steps to ensure the safety of all medications on the market.
