NDMA & NDEA: What’s the Difference?

In July 2018, the FDA recalled certain batches of valsartan after investigators found N-Nitrosimethylamine (NDMA) had contaminated the drug. Since then, several batches of valsartan, irbesartan, and losartan have been recalled due to NDMA and N-Nitrosodiethylamine (NDEA) contamination. These nitrosamines are classified as probable human carcinogens.

How Are They Similar?

NDMA and NDEA are both classified by the Environmental Protection Agency as probable human carcinogens. Exposure to these carcinogens can cause tumors to develop in the respiratory tract. Specifically, an individual may develop liver, stomach, colorectal, pancreatic, prostate, esophageal, and/or intestinal cancer. Exposure has also been linked to non-hodgkin’s lymphoma, leukemia, and multiple myeloma.

What’s the Difference?

The main difference between NDMA and NDEA is toxicity. NDEA happens to be about three times more toxic than NDMA.

What Should I Do?

If you or a loved one took a recalled valsartan, irbesartan, or losartan and developed prostate cancer (before age 60), lower esophageal cancer, non-hodgkins lymphoma, leukemia, multiple myeloma, colon, stomach, intestinal, or pancreatic cancer, please fill out the form below.

Valsartan Side Effects

In July 2018, the blood pressure medication Valsartan was recalled due to contamination with a probable human carcinogen. The FDA estimates that between 3 and 3.7 million people have been prescribed Valsartan over the last three years. Many are scared and wondering what side effects this contaminated medication could cause.

What Are the Valsartan Side Effects?

There are several risks associated with Valsartan that are warned about in the drug label. However, the recent discovery of N-nitrosodimethylamine (NDMA) contamination found in suppliers’ plants has added a terrifying new side effect: cancer. NDMA is a probable human carcinogen. Researchers use NDMA to induce cancer in animal studies and have found in various species, including rats and mice, that tumors developed in the liver, respiratory tract, and blood vessels after being induced with NDMA.

Valsartan side effects due to NDMA contamination include cancers of the liver, pancreas, prostate, esophagus, colon/intestines, and stomach. Contamination has also been linked to non-hodgkin’s Lymphoma, leukemia, and multiple myeloma.

What Should I Do If My Valsartan Was Part of the Recall?

If you or a loved one received a Valsartan recall letter, you should speak with your doctor immediately. FDA drug safety officials have alerted doctors and physicians about this, but they recommend you do not stop taking your medication without first contacting your physician. You can see which Valsartan medications were recalled here.
