Valsartan Lawsuit – Legal Claims by Cancer Victims (2022 Updates)

A Valsartan lawsuit is a legal claim for money damages brought by a consumer who took the blood pressure medication and was subsequently diagnosed with cancer. The lawsuits allege that many batches of Valsartan from 2012 to 2018 were contaminated with NDMA, a probable human carcinogen. Hundreds of Valsartan products made in China have been recalled. This is the same carcinogen that is currently the subject of Zantac lawsuits.

Shouse Law Group is assisting victims from across the United States to bring lawsuits against more than 20 drug manufacturers. We are seeking to collect financial compensation for serious side effects and complications.

The current litigation is not a class action lawsuit for Valsartan users. It is a mass tort where each individual brings a claim separately. Because of the large number of claims, Valsartan cancer lawsuits have been consolidated into a multi-district litigation based in New Jersey.

It may not be too late to bring a 2022 Valsartan lawsuit. Our law firm is currently accepting cases that meet the following criteria:

1. The patient took Valsartan during the period 2014 or later, and
2. After at least one year since starting the drug – and after taking it for at least 30 days – the patient was diagnosed with one of the following cancers:

• • Liver cancer,
  • Kidney cancer,
  • Stomach cancer,
  • Bowel cancer,
  • Intestinal cancer (including colon or rectal cancer),
  • Esophageal cancer,
  • Pancreatic cancer,
  • Bladder cancer,
  • Leukemia,
  • Prostate cancer,
  • Colorectal cancer,
  • Non-Hodgkins lymphoma, or
  • Multiple myeloma

Patients who took Valsartan are advised to take the following five steps:

1. Check here for FDA updates and to see if their particular medicine is on the recall list,
2. Talk to their doctor about an alternative drug or treatment,
3. Gather their medical and insurance records,
4. Keep any recalled Valsartan pills and bottles they still have as evidence, and
5. Talk to a Valsartan lawsuit attorney

There is a limited statute of limitations to file a claim depending on the state. So contact an attorney quickly.

In this article, our Valsartan lawyers will answer the following seven key questions about the current litigation:

• 1. What are the legal grounds for a Valsartan lawsuit?
• 2. What is the link between Valsartan and cancer?
  • 2.1. What is NDMA?
  • 2.2. What kind of cancer does Valsartan cause?
• 3. Has the FDA recalled Valsartan?
  • 3.1. Which Valsartan has been recalled?
  • 3.2. Is Valsartan safe now?
• 4. When will the case settle? How big will it be?
• 5. Is the litigation a Valsartan class action lawsuit?
• 6. How does Valsartan work?
• 7. How do I choose a lawyer?

We cite legal authorities and peer-reviewed scientific literature.

Many drug companies have voluntarily recalled their Valsartan drugs.

1. What are the legal grounds for a Valsartan lawsuit?

Two common claims in the 2022 Valsartan lawsuits are:

1. The pills had a manufacturing defect; and
2. The pills had improper labeling which failed to warn about the dangers

Plaintiffs do not need to prove that the manufacturers intended to cause harm or even that the manufacturers were negligent.

Instead, manufacturers are held “strictly liable” under products liability for their manufacturing defects and inadequate warning labels. Therefore, the plaintiff just needs to prove that the manufacturer made a major mistake that caused their illness.

1.1 Manufacturing defect

A manufacturing defect occurs when a product that has a safe design becomes unsafe due to poor construction.

Valsartan is an angiotensin ii receptor blocker (arbs) that is safe when it is compounded correctly. However, several hundreds of lots became unsafe when they were contaminated during the manufacturing process in China with possible cancer-causing agents.

In order to win a manufacturing defect product liability claim, the plaintiff would therefore need to prove:

• The drug had a manufacturing defect when it left the manufacturer’s possession; and also
• This defect was a substantial factor in causing the plaintiff’s harm

The FDA (U.S. Food and Drug Administration) has made public which lots of Valsartan contain unacceptable amounts of carcinogens. Consequently, plaintiffs would need to show that the pills they ingested came from those affected lots. Old pill bottles could serve as evidence of this. Prescription records from the pharmacy could also serve as evidence.

In order to prove that the Valsartan caused the plaintiff’s cancer, the plaintiffs’ attorneys could therefore present such evidence as:

• Medical records that show the plaintiff developed cancer after taking Valsartan with NDMA, and
• Expert witness testimony and medical journal articles explaining the link between Valsartan and cancer

1.2 Improper labeling/ failure to warn

All medication including Valsartan carries risk. Therefore, the manufacturers are required to disclose these risks in the form of warning labels and instructions.

However, none of the contaminated Valsartan pill bottles warned that they may contain carcinogens. Had doctors and patients known of this risk, they likely would have chosen another medication instead.

In sum, failure to warn is a straightforward claim to prove in court. The plaintiffs’ attorneys would show how the pill packaging and instructions omitted important information. The plaintiffs can also testify that they would not have taken the pills but for this misinformation.¹

Valsartan is a popular high blood pressure and heart failure drug. It may also increase lifespan for heart attack patients with left ventricle problems.

2. What is the link between Valsartan and cancer?

The chemical NDMA that contaminated more than one thousand lots of Valsartan medications has been shown to cause cancer. NDMA is short for N-nitrosodimethylamine. In short, the active ingredient Valsartan is a cancer risk due to NDMA contamination. The affected Valsartan pills often contain 400 times the safe daily threshold of NDMA.

Authorities believe that Valsartan contamination is an unexpected byproduct of changes in how the drug is manufactured. The contamination has apparently been taking place since 2012. This is when ZHP of China started manufacturing the generic drug pills.

ZHP stands for Zhejiang Huahai Pharmaceuticals. ZHP made most of the world’s Valsartan. (Another Chinese manufacturer that made contaminated Valsartan is Zhejiang Tianyu.) Ultimately, more than 30 different companies made generic Valsartan. This contamination has allegedly occurred for years until random testing uncovered the contamination.

The US Environmental Protection Agency (EPA) classifies NDMA as a “probable human carcinogen” (commonly called a B2 carcinogen). This means that it probably causes cancer in humans since it causes cancer in animals. Scientists often use NDMA to cause cancer in rats for research. In the past, people have also used NDMA as poison in murders:

• In 1978, a German court convicted a chemistry teacher who attempted to murder his wife by mixing NDMA into her blackberry jam.
• Also in 1978, a court sentenced a man in Omaha, Nebraska, to death for killing a baby and a 24-year-old man by putting NDMA into their lemonade.
• In 2013, a student in China put NDMA into a water cooler and poisoned his roommate. He died 15 days later.²

2.1. What is NDMA?

The World Health Organization lists the chemical NDMA as “probably carcinogenic to humans.” Federal regulations list NDMA as a “priority toxic pollutant.” The U.S. National Library of Medicine says NDMA is “reasonably anticipated” to cause cancer in humans. A 2018 Danish study showed that NDMA exposure can cause cancer of the liver, stomach, colon, rectum, and pancreas. Also, the EPA reports that NDMA exposure may cause liver damage.³

NDMA has been used to make antioxidants, softeners for copolymers, additives for lubricants, and other industrial products. This chemical is a byproduct of some pesticide and rubber tire manufacturing. NDMA was required to synthesize UDMH (unsymmetrical dimethylhydrazine), an ingredient of rocket fuel. The WHO also states NDMA is a byproduct of municipal wastewater treatment facilities and some industrial manufacturing facilities. Trace amounts of NDMA – which are not harmful – are sometimes found in bacon.

The FDA ran further tests on Valsartan batches that contained NDMA and also found a second carcinogen in some of the drugs. This second carcinogen is called N-nitrosodiethylamine (NDEA). NDEA causes cancer in animals and is used to induce liver tumors for research. It is also “reasonably anticipated” to cause cancer in humans.

(Another carcinogen that was also found in Losartan is N-Nitroso-N-methyl-4-aminobutyric acid (NMBA).)⁴

Note that many Valsartan pills were compounded with hydrochlorothiazide (HCTZ), which is a water pill and is safe.

Many Valsartan pills are contaminated with NDMA. This is a carcinogen.

2.2. What kind of cancer does Valsartan cause?

Animal studies have associated NDMA with the following diseases:

• Colorectal cancer,
• Gastric cancer,
• Esophageal cancer,
• Multiple Myeloma,
• Non-Hodgkin’s Lymphoma,
• Leukemia,
• Prostate cancer,
• Pancreatic cancer, and also
• Liver cancer⁵

In addition, people overexposed to NDMA in the short-term may exhibit such symptoms as:

• headaches
• dizziness
• jaundice
• enlarged liver
• liver fibrosis and scarring
• fever
• nausea and vomiting
• stomach cramps, and/or also
• impairment of lungs, liver, or kidneys

7. How do I choose a lawyer?

In sum, choose a personal injury attorney committed to fighting for the maximum possible settlement and staying in contact with clients.

Steer clear of lawyers who want payment upfront. Reputable attorneys also accept no money unless they win the case.

Therefore, look for attorneys with a track record against Big Pharma. Drug companies hire bullying law firms. They do everything to intimidate victims and delay proceedings.

But experienced plaintiffs’ attorneys stay the course and they have one focus: Recovering the largest financial reward available in a 2022 Valsartan lawsuit.
