Trustwell Law is now accepting cases on behalf of persons who have been diagnosed with certain cancers after having taken valsartan1 for at least a year beginning in 2015 or later.
The valsartan lawsuits are based on evidence that many batches of valsartan1 were contaminated with one or more of the cancer-causing chemicals N-nitrosodimethylamine (NDMA)2 or N-Nitrosodiethylamine (NDEA)3.
On July 5, 2018, the European Medicines Agency (EMA) announced it would review all medicines containing valsartan after tests had shown NDMA in batches of the drug manufactured by Zhejiang Huahai Pharmaceutical Co., Ltd (ZHP), a major supplier of generic valsartan.
On July 13, 2018, the Food and Drug Administration (FDA) announced a “voluntary recall of several drug products” containing valsartan due to the presence of NDMA in those products. According to the FDA “[t]he presence of NDMA was unexpected and is thought to be related to changes in the way the active substance [valsartan] was manufactured.”
As the FDA, the EMA, and other agencies investigated, more recalls of generic valsartan followed, valsartan from another supplier (Hetero Labs Ltd.) was found to contain NDMA, and tests found NDEA in some valsartan products.
Long-term exposure to NDMA and NDEA has been linked to many types of cancer, including:

The FDA first approved valsartan in 1996 under the brand name Diovan® to treat hypertension (high blood pressure) and in 2001 extended that approval to treat heart failure in certain classes of patients. Since the manufacturer Novartis’ patent protection expired in 2012, many generic competitors have entered the market. Valsartan is available by prescription both alone and in combination products.
Valsartan belongs to the class of drugs known as angiotensin II receptor blockers (ARBs), and it treats hypertension by occupying the same receptors on cells lining the blood vessel walls targeted by the hormone angiotensin II. Angiotensin II is a hormone the body produces that binds with receptors on cells lining the blood vessel walls (a bit like plugging into a tiny socket) and causes the blood vessels to constrict and blood pressure to increase. When valsartan molecules beat angiotension II molecules to those receptors, they block the hormone from attaching to the cells, prevent the blood vessels from constricting (or relax the vessels), and lower blood pressure or keep it low.
NDMA and NDEA are very dangerous chemicals. According to the FDA, these “genotoxic” chemicals “are of special concern to global regulators because…they have the potential to cause harm at very low levels.”
NDMA and NDEA are hepatotoxins (chemicals that cause liver damage) and mutagens (chemicals that cause birth defects). They are classified as “probable human carcinogen[s]” by the Environmental Protection Agency (EPA) and the World Health Organization. The EPA lists NDMA as an “extremely hazardous substance” for which facilities are legally required to provide state and local authorities information for emergency response plans and emergency notification of chemical releases4.
Before June 2018, regulators had not identified NDMA and NDEA as possible valsartan contaminants, so the required tests did not look for those carcinogens. But on June 19, 2018, a U.S. manufacturer informed the FDA that the company selling it valsartan had found NDMA in its product. The supplier, Zhejiang Huahai Pharmaceutical Co., Ltd (ZHP), was a major source of generic valsartan.
In early July 2018, the EMA announced it would review all medicines containing valsartan because of the reports of NDMA in valsartan manufactured by ZHP. A few days later, the FDA announced its first “voluntary recall” of several drug products containing valsartan due to NDMA.
The FDA, EMA, and other agencies have continued to investigate the causes of the contamination and look for solutions. Tests have found NDMA in valsartan from another generic supplier (Hetero Labs, Ltd). Tests have also revealed other valsartan products contaminated with NDMA and some contaminated with NDEA. Many more recalls have followed.
NDMA’s properties “make it hard to detect in standard laboratory testing,” but the FDA has developed new test methods specifically designed to identify and quantify NDMA and NDEA in valsartan products. The FDA also says it has identified how the contamination most likely happened, beginning several years ago when certain suppliers changed their manufacturing process and reused certain chemicals.
The first round of voluntary recalls announced in July 2018 included valsartan products manufactured by Prinston Pharmaceuticals (labeled as Solo Healthcare), Teva Pharmaceuticals (labeled as Actavis LLC), and Teva Pharmaceuticals (labeled as Major Pharmaceuticals). These products were recalled for NDMA contamination and were made using valsartan from ZHP.
The FDA maintains a searchable list for consumers and healthcare professionals of all valsartan products and other ARB drugs recalled due to NDMA or NDEA contamination.
Patients who have been diagnosed with cancer after taking contaminated valsartan have sued the manufacturers to seek compensation for their injuries. These cases are in their early stages, and there have been no outcomes announced (verdicts or settlements) in any lawsuit based on contaminated valsartan.
The first step in this process typically involves large groups of cases being combined in federal court for discovery and other pre-trial purposes in what is called a Multidistrict Litigation (MDL).
In February 2019, a federal court in the District of New Jersey established an MDL for valsartan. By October 2019, more than 100 lawsuits were pending in the MDL.
Generally, groups of tort cases do not settle until after several “bellwether” cases have been tried to a jury. The results of those trials allow the manufacturer and plaintiffs to better understand the impact of the available evidence and the gauge the risks of continued litigation.
