What is the Cancer-Causing Agent in Zantac?

Riddle Brantley LLP   |  April 13, 2020   |  

WARNING: The FDA has issued a Zantac recall and asked manufacturers of Zantac and ranitidine to stop selling the prescription and over-the-counter medications. This is based on potential contamination by the cancer-causing agent in Zantac: NDMA.

In the wake of the FDA’s warning that Zantac may cause cancer, many are wondering: “What is the cancer-causing agent in Zantac?”

NDMA is a potentially cancer-causing agent in Zantac that may result in the development of many types of cancer, including:

What is NDMA?

What is the Cancer-Causing Agent in Zantac_ - Riddle & BrantleyNDMA (N- Nitrosodimethylamine) is a potentially dangerous and cancer-causing chemical that is classified as a “probable carcinogen” by the World Health Organization (WHO).

According to Dr. William Mitch, a professor at Stanford University, NDMA is a cancer-causing agent “because it modifies your DNA.”

NDMA occurs in industrial and natural processes, and is even found in trace amounts in many foods and even water. In low doses, ingestion of NDMA is not thought to cause cancer, but elevated levels of NDMA – such as found in Zantac – present a serious cancer risk.

The FDA lists the maximum permissible daily exposure to NDMA in pharmaceuticals as 96 ng. However, independent tests have discovered more than 40,000 ng of NDMA present in the urine of study subjects who had taken ranitidine.

In recent years, elevated levels of NDMA have also been discovered in groundwater in the United States.

What does NDMA do to humans?

In high doses, such as those detected in Zantac and ranitidine, NDMA may cause various types of cancer (see above), but there are additional dangers, as well.

Potential symptoms and conditions associated with elevated levels of NDMA in humans include but are not necessarily limited to:

  • Jaundice
  • Nausea
  • Fever
  • Dizziness
  • Vomiting
  • Abdominal cramps

According to a report, high levels of NDMA may also cause reduced function of the kidneys and lungs.

IMPORTANT: If you’ve experienced any of these symptoms after taking Zantac or generic ranitidine (either prescription or over-the-counter), consult with your doctor right away. Zantac alternatives are available.
