Valsartan Containing NDMA

Valsartan Lawsuit Update - IL Class Action Claims Walgreens Failed To Warn Consumers of Valsartan Dangers

February 19, 2020 - Illinois class action claims that Walgreens failed to warn consumers that one of the high blood pressure medications available from the pharmacy, Valsartan, was a toxic drug containing a suspected carcinogen.

The lawsuit was filed in Cook County Circuit Court on Friday. The lawsuit claims that Walgreens Boots Alliance Inc. materially misrepresented the safety of Valsartan, which had been recalled by the FDA due to the presence of probable carcinogen N-nitrosodimethylamine, or NDMA, and N-nitrosodiethylamine, or NDEA, a suspected human and known animal carcinogen.

Plaintiffs claim that Walgreens was aware that the product was toxic, but failed to warn consumers, putting them at risk.

Harry Shanov, plaintiff, said that if he, himself, or other members of the class action knew of the alleged health risks associated with Valsartan, they would have not purchased the product.

According to the complaint, plaintiff consumers believed that they were purchasing Valsartan "and only Valsartan, as opposed to Valsartan that contained elevated and unsafe levels of NDMA and NDEA."

Shanov says that his prescription was also misleading. Based on the label of his prescription, he believed that Valsartan did not pose any “undisclosed increased risk” of health risks.

What is Valsartan?

Valsartan is an off-patent active ingredient in a number of generic drugs, including drugs used to treat hypertension, heart failure, left ventricular failure, and left ventricular dysfunction following myocardial infarction. Valsartan is classified as an angiotensin receptor blocker (ARB). Valsartan works by relaxing blood vessels, allowing blood to flow more easily.

Valsartan is also sometimes prescribed with hydrochlorothiazide (HCTZ) to treat hypertension.


What are the Dangers of Taking Valsartan?

Valsartan has been associated with an increased risk of developing cancer in the liver, kidney, stomach, or intestines.
Along with the most serious dangers of taking valsartan, there are a number of side effects associated with valsartan.

Valsartan side effects include:

  • Dizziness
  • Low blood pressure
  • Diarrhea
  • Joint and back pain
  • Tiredness
  • Symptoms of high blood potassium, including rhythm problems, muscle weakness, and slow heart rate.


NDMA Found in Valsartan

Chinese manufacturer Zhejiang Huahai Pharmaceutical first discovered that the generic valsartan products that the company was producing contained impurities, including N-nitrosodimethylamine (NDMA).

Zhejiang Huahai Pharmaceutical supplied these generic drugs containing NDMA to US-based pharmaceutical companies Major Pharmaceuticals, Solco Healthcare, and Teva Pharmaceuticals Industries Ltd. These companies then processed and distributed the drugs to the US market.


What is N-nitrosodimethylamine (NDMA)?

NDMA is an organic chemical compound that has been labeled as a probable human carcinogen, according to the International Agency for Research on Cancer (IARC).

NDMA is found in a variety of products ranging from lubricants and softeners to rocket fuel.

NDMA can be produced through chemical reactions that occur in the manufacturing process.

NDMA is the byproduct of the manufacturing of certain pesticides, fish processing, and the production of rubber tires.

NDMA can also be found naturally, in trace amounts in certain foods. NDMA is released in these foods through chemical reactions during the food preparation process. For example, NDMA can be produced by grilling, browning, and salting of certain meats.

Studies on animals have shown NDMA to be a carcinogen, causing cancerous tumors to form on the liver, kidney, and respiratory tract. Liver cancer, gastric cancer, colorectal cancer, kidney cancer, lung cancer, and nasal cancer have all been associated with NDMA, but it appears to be a universal carcinogen, meaning it has the potential to cause cancer in almost all organs. For these reasons, NDMA has been labeled a probable human carcinogen.

NMDA exposure has also been associated with non-cancerous liver damage, according to the US Department of Health and Human Services.


How Dangerous is NDMA?

Based on lab testing, NDMA is classified as a probable human carcinogen. NDMA is found naturally and at low levels in water and foods such as meats, dairy, and vegetables.

Extremely small levels of NDMA found in foods are not harmful. However, higher levels of NDMA are associated with an increased risk of a number of serious cancers and liver damage.

NDMA contamination in valsartan is high enough that it has sparked major concern from manufacturers, federal oversite institutions, and consumers. While NDMA has not yet been labeled a known human carcinogen, it is still likely to be dangerous to humans.


Is Valsartan Bad for the Kidneys?

Valsartan is difficult to metabolize, often causing stress on the liver. Valsartan has been linked to an increased risk of developing kidney cancer. This is due to the presence of NDMA, which is a probable carcinogen found in valsartan.


Is Valsartan Hard on the Liver?

Valsartan can cause liver damage. Valsartan also increases the risk of developing liver cancer.


Are Valsartan and Losartan the Same?

Both Valsartan and Losartan are classified as angiotensin receptor blockers (ARBS). Although they have the same classification, losartan and valsartan are not the same. There are a number of notable differences, including dosage, length of effectiveness, and uses.


FDA Announces Valsartan Recall

In July 2018, the U.S. Food and Drug Administration (FDA) issued a recall of a number of pharmaceutical drugs containing valsartan used to treat hypertension (high blood pressure) and heart failure due to the increased risk of certain cancers associated with NDMA. Not all drugs containing valsartan were named in the recall.

The following were named in the recall:

  • Major Pharmaceuticals valsartan products
  • Solco Healthcare valsartan products
  • Teva Pharmaceuticals Industries Ltd. valsartan products
  • Solco Healthcare valsartan/HCTZ products
  • Teva Pharmaceuticals Industries Ltd. valsartan/HCTZ products

“We have carefully assessed the valsartan-containing medications sold in the United States, and we’ve found that the valsartan sold by these specific companies does not meet our safety standards. This is why we’ve asked these companies to take immediate action to protect patients,” said Dr. Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research.

The FDA issued a press release along with the recall announcement – “The presence of NDMA was unexpected and is thought to be related to changes in the way the active substance was manufactured,” the FDA release said.

The FDA is now conducting a full-length investigation into the safety of the recalled products.

The FDA stresses the importance that patients DO NOT stop taking the recalled products altogether – the danger of abruptly discontinuing the use of this medication greatly outweighs the risks associated with short-term NDMA exposure – patients should rather contact their healthcare provider right away to discuss alternative medication options.

22 other countries that had previously recalled valsartan products prior to the FDA valsartan recall.

Filing a Valsartan Lawsuit

Claims are being investigated against manufacturers and distributors of hypertension medications containing the active ingredient valsartan, which contains the probable human carcinogen N-nitrosodimethylamine (NDMA). Major Pharmaceuticals, Solco Healthcare, and Teva Pharmaceuticals Industries Ltd. sold hypertension and heart failure medication containing valsartan, putting consumers at risk of developing a number of life-threatening cancers.

If you or a loved one believe that you have suffered an injury as a result of NDMA in valsartan, you may be eligible to participate in a valsartan lawsuit. Contact a valsartan injury lawyer today to determine whether you qualify for a valsartan lawsuit.


Steps in a Valsartan Lawsuit

You should begin to collect evidence as soon as possible following your injury. Familiarize yourself with the steps of civil litigation, so that you are aware of the process of a valsartan lawsuit.  Then, you should hire a personal injury attorney, preferably a valsartan injury lawyer.

It is important that you seek proper medical treatment, follow your doctor’s orders, and mitigate injuries and future problems.

Do not hesitate to contact a valsartan injury lawyer – your state’s statute of limitations limits the amount of time you have to file a valsartan lawsuit, so you should begin the process as soon as possible.

Your valsartan injury lawyer will be able to assess damages for your case to determine the amount of compensation you should demand from the defendant. Liability in a valsartan lawsuit depends on the company and manufacturers where the drugs containing valsartan originated from – your valsartan injury lawyer will be able to determine which parties are liable.  In many valsartan lawsuits, plaintiffs will decide to file both compensatory damages and punitive damages against the defendant.

Once you have mitigated injuries, began collecting evidence, assessed damages, determined the liable party, and hired a valsartan injury lawyer, you can file your valsartan lawsuit.
