Based on results of laboratory testing, the U.S. FDA has learned that Zantac® and other ranitidine based medications contain a nitrosamine impurity called N–nitrosodimethylamine (NDMA) at low levels. NDMA is thought of as a likely human carcinogen – a substance that could cause cancer in humans. NDMA is a classified environmental contaminant and found in water and food sources, including meats, dairy items, and produce.


What is NDMA?

N–nitrosodimethylamine (NDMA) is considered as a likely human carcinogen that means that it is more probable than not to cause cancer in humans. NDMA has been studied in animal populations and observed to increase the occurrence of cancer in the animals. The studies have enhanced the opportunity of an connection between NDMA and liver toxicity that might lead to the development of liver cancer and various connected conditions brought about by an NDMA–induced reaction to the liver.


The degree and duration of human NDMA exposure that may begin the development of cancer is not exactly known. Also, the amount and duration of the NDMA contamination of Zantac® and other ranitidine medications are not precisely known.


Diseases Associated with Exposure to NDMA

NDMA has been researched in animal groups and determined to increase the happening of cancer in the animals. In light of these studies, the Environmental Protection Agency classifies NDMA as a likely human carcinogen. The research has raised the likeliness of a connection between NDMA and liver toxicity that can lead to the development of liver cancer and various related issues created by an NDMA injury to the liver. Others have stated that NDMA may also be associated to other cancers such as:


Stomach Cancer, Esophageal Cancer, Pancreatic Cancer, Leukemia.


Have Other Ranitidine Products Been Affected?

 zantac  . Food and Drug Administration has alerted health care professionals and consumers to three existing voluntary recalls of ranitidine.


Perrigo Company plc has voluntarily recalled over–the–counter (OTC) ranitidine tablets because of the possibility of N–Nitrosodimethylamine (NDMA) in the medication.

Novitium Pharma LLC has voluntarily recalled all unexpired amounts and lots of ranitidine hydrochloride capsules because of the possibility of NDMA in the medicine.

Lannett Company, Inc. has voluntarily recalled all unexpired lots of prescription ranitidine syrup because of the presence of NDMA found in the drug.

Should I Cease Taking Zantac® or Other Ranitidine Medications?

On October 28, 2019, the FDA advised patients and consumers taking Zantac® and other ranitidine medicines as follows:


“Patients taking prescription ranitidine who wish to stop should talk to their health care professional about other treatment options. Consumers taking OTC ranitidine, which is used to prevent and relieve heartburn associated with acid indigestion and sour stomach, may consider using other OTC products approved for their condition. FDA’s testing of samples of alternatives such as Pepcid (famotidine), Tagamet (cimetidine), Nexium (esomeprazole), Prevacid (lansoprazole), and Prilosec (omeprazole) show no NDMA in these medicines.”
