Valsartan Cancer Lawsuit Attorney

Generic Valsartan (brand name Diovan) is a popular medication to treat hypertension and congestive heart failure (CHF) prescribed by doctors.

Valsartan is an angiotensin ARB (angiotensin II receptor blocker). It increases a patient’s longevity after a heart attack because it is known to relax blood vessels and improve blood flow.

The medication also helps lower blood pressure, prevent stroke, and prevent kidney malfunction in diabetes patients. Millions of Americans have taken the drug for high blood pressure, Valsartan, for these conditions.

Blood Pressure Medications: Valsartan, Losartan and Irbesartan

Pharmaceutical companies have developed and manufactured angiotensin II receptor blockers (ARBs) to regulate blood pressure or hypertension for decades.

The active ingredient in blood pressure medicine, such as Valsartan, Losartan, and Irbesartan, were manufactured and widely prescribed by doctors to patients with hypertension.

The Valsartan medications block the hormone angiotensin II, narrowing and tightening blood vessels. The drugs relax these arteries allowing blood to flow more freely.

It decreases blood pressure due to more blood flowing through the body, which is why these drugs are ideal for patients suffering from hypertension, congestive heart failure, and other conditions.

Valsartan was one of America’s most widely preferred pharmaceuticals to treat hypertension. It became popular when Novartis Pharmaceuticals Corporation released it in 1996.

The medication was manufactured in pill form to be taken orally once a day for hypertension, heart failure, kidney malfunction in diabetes patients, and other conditions.

FDA Drug Approval

The FDA announced the approval of the drug because it had been stated that it “may reduce patient’s risk of having a heart attack or stroke,” making it a popular choice among doctors and patients.

The ARB drug was a replacement treatment for similar medications, including Captopril and Enalapril, known to cause side effects such as dizziness, hypotension, kidney disease, and heart failure.

While the ARB appeared less dangerous, it was less effective than the original medications. Despite this, doctors still widely used and prescribed Valsartan pills because they offered a safer alternative to help patients suffering from hypertension and other heart conditions live longer lives.

Valsartan contamination of the generic medication manufactured in China led to increased cancer cases due to the n nitrosodimethylamine (NDMA) exposure.

At the same time, the Food and Drug Administration (FDA) announced a recall, and the EMA (European Medicines Agency) began reviewing the medication due to increasing Valsartan claims of adverse effects like hepatic or renal impairment, hyperkalemia, and mitral valve/aortic stenosis.

Food and Drug Administration Recall of Valsartan High Blood Pressure Medication Due to NDMA Contamination

In July 2018, the US Food and Drug Administration (FDA) recalled some Valsartan products, including the generic drug, after discovering the drug had been contaminated with NDMA linked to cancer during the manufacturing process.

The federal agency said traces of the carcinogenic compound N-nitrosodimethylamine (NDMA) were found in Valsartan during manufacturing.

For decades, NDMA had been used in rocket fuel, among other things, before being used in dangerous drugs, including Diovan (Valsartan). This recall is the subject of “mass tort” federal cancer lawsuits involving Valsartan pills currently working their way through the federal court as MDL (multi-district litigation).

Exposure to elevated levels of NDMA can seriously damage the liver and increase the risk of developing liver, gastrointestinal tract, stomach, kidneys, and colon cancer, even in relatively small amounts.

The organic chemical is known to cause cancer in research animals and is considered a “probable” human cancer-causing agent by the medical community.

Other potential cancers caused by Valsartan products (Diovan) include intestinal cancer, gastric cancer, pancreatic cancer, esophageal cancer, kidney cancer, prostate cancer, multiple myeloma, non-Hodgkin’s lymphoma, and leukemia.

Valsartan Lawsuits: Allegations Against Zhejiang Huahai Pharmaceuticals with a Probable Human Carcinogen

There are legal grounds to file a Valsartan lawsuit against the pharmaceutical company.

The basis of a legal argument might include the pharmaceutical company’s manufacturing defect of Valsartan pills or tablets, improper black box labeling of the drug to identify life-threatening side effects, and a failure to warn the consumer about the potential dangers of severe harm or death.

By reviewing your medical records, we can determine if you or a loved one qualify for a Valsartan lawsuit. As a plaintiff in a Valsartan lawsuit, you will not be required to prove that the pharmaceutical company intended to cause you harm.

Your attorney will only need to show that the pharmaceutical company negligently acted when designing, manufacturing, distributing, or marketing the product.

Holding the Manufacturer Accountable

Your attorney will likely hold the drug manufacturer accountable under strict liability laws and prove that there were manufacturing defects that the pharmaceutical company knew or should have known, and they failed to provide adequate warning labels.

Showing that the manufacturer caused illness due to a significant mistake is the first step to associating the drug maker’s negligence and their responsibility for compensating you for your damages.

You are probably understandably alarmed and confused if you take Valsartan (Diovan or generic Valsartan).

The Status of Valsartan Litigation

Since the recall, thousands of plaintiffs around the country have filed Valsartan lawsuits against the drug makers mentioned earlier (including China’s Zhejiang Huahai) and drug store retailers, including Walgreens and Wal-Mart.

The Valsartan lawsuits allege negligence, strict liability, failure to warn, fraud, and breach of express and implied warranty of merchantability, among other causes of action. Many of these tainted Valsartan cases remain unresolved.

Valsartan Class Action Lawsuit

A Valsartan class action lawsuit was filed against the pharmaceutical company and several distributors. The Valsartan class action lawsuit has been consolidated in the District of New Jersey federal court in what is known as Multidistrict Litigation (MDL).

The Valsartan MDL (Valsartan MDL 2875) is pending before Judge Robert B. Kugler, USDJ, and Judge Joel Schneider, USMJ. The defendants are being sued by plaintiffs who took the recalled Valsartan and who claim it put them at risk for cancer.

The plaintiffs claim in one argument that the drug companies should have been aware of safety problems involving Zhejiang that predate the Valsartan recall.

The litigation is still in its early stages, and no Valsartan lawsuit settlements or verdicts related to contaminated Valsartan products have yet been announced.

Valsartan-Related Cancers of the Digestive System

It seems N-nitrosodimethylamine (NDMA) wreaks the most havoc on the liver more than any other organ. It has been known to cause severe and non-cancerous liver conditions in humans and is used by cancer researchers to induce liver tumors in rodents.

Cancer of the liver

Generally, it has a poor prognosis because the liver is a vital organ essential to bodily function. Most liver cancers are the secondary cause, meaning that cancer originated in another organ or bodily system and spread or metastasized to the liver.

Alternatively, primary cancer of the liver originates in the organ and accounts for only two percent of cancers in the US. Its causes include hepatitis, alcohol abuse, smoking, and possibly obesity. Primary liver cancer strikes twice as many men as women, at an average age of sixty-seven.

A few benign and cancerous tumors can develop in the liver. Because of that, the symptoms of cancerous and non-cancerous could be similar.

Symptoms of cancer of the liver include:

  • Unexplained weight loss
  • Loss of appetite
  • Upper abdominal pain
  • Nausea and vomiting
  • Fatigue
  • Jaundice of the skin or eyes
  • White, chalky stools

Cancer in the liver is generally treated through surgical removal of tumors and chemotherapy.

Stomach Cancers

Adenocarcinoma is generally more treatable than cancer in the liver, with a higher survival rate, especially when caught early. GERD and Acid Reflux are often precursors of liver cancer.

Researchers also believe there is a correlation between this gastric cancer and obesity, smoking, and an unhealthy diet. Some symptoms of stomach cancers can be like cancer in the liver and include:

  • Fatigue
  • Feeling bloated after eating
  • Feeling full after eating small amounts of food
  • Persistent heartburn
  • Nausea or vomiting
  • Stomach pain
  • Weight loss

Doctors usually recommend treatments for stomach cancer depending on how the disease has progressed and the need for surgery (including removal of the stomach), radiation, and chemotherapy.

Colorectal Cancer

Colon (intestinal) cancer is among the most common types of cancer in the US. It is treatable and even curable if diagnosed early. This form of cancer is most common among older adults but can strike anyone at any age.

Most cancer of the colon starts as polyps, or growths, on the inner lining of the colon or rectum. If precancerous polyps are not removed, they can degrade into cancer.

Colon and rectal cancer risk factors include a diet high in fat or red meat, a family history, and being over age fifty. Doctors advise men and women over fifty years of age to undergo colonoscopies every five years to find polyps and remove them.

Symptoms of colon cancer include:

  • Changes in bowel habits
  • Unexplained weight loss
  • Rectal bleeding or blood in stool
  • Persistent abdominal discomfort

Treatment for colorectal cancer is relatively similar to stomach cancer and includes removing cancerous tumors and, if necessary, parts of the colon (colostomy) or rectum and chemotherapy.

Tainted Valsartan Litigation FAQs

If you have been prescribed the high blood pressure drug Valsartan and experience minimal or severe side effects, you are likely alarmed by the recall. Losartan and Valsartan impurities have been detected in angiotensin ii receptor blockers.

A Valsartan lawyer specializing in personal injury lawsuits from our law offices provides answers below to many of the questions posed by concerned patients just like you, including:

What Are the Side Effects of Valsartan?

Many patients are given Valsartan and have used the medication for weeks or months know that significant side effects range from mild headaches to low blood pressure.

The US Food and Drug Administration included a black box warning with each prescription warning patients of associated fetal toxicity when taking Valsartan pills.

The most common effects experienced by patients tend to be brief and mild. They include:

  • Nausea
  • Coughing
  • Headaches
  • Diarrhea
  • Fatigue
  • Low blood pressure
  • High blood potassium (hyperkalemia)
  • Weight gain
  • Possible hair loss
  • Allergic reaction
  • Reduced renal function (kidneys)
  • Fetal toxicity
  • Impotence
  • Acute liver injury

Liver damage is a significant problem when taking Valsartan, though reports are rare. During clinical trials, some participants who were given Diovan, the generic form of Valsartan, displayed elevated liver chemistries on occasion.

These individuals were dropped from the study and stopped taking the medication due precisely to their elevated liver chemistries to ensure their safety.

What is NDMA?

N-nitrosodimethylamine NDMA is an organic compound classified as a waste product of industrial processes, including the making of lubricants and pesticides. It is part of the N-nitrosamine family of potent carcinogens.

The yellowish liquid is often present at supposedly safe micro levels in some food products—particularly cured meats—and, water supplies, even beer. The toxic chemical is known to damage the liver and other human organs and cause cancer in laboratory rats.

The US Environmental Protection Agency (EPA) concluded that NDMA is a “probable human carcinogen” that can increase a person’s risk of developing cancer. Most of what is currently known about NDMA’s carcinogenic qualities comes from animal-based studies.

However, the World Health Organization (WHO) reported that several case-control studies and one cohort study of dietary intake of NDMA by humans showed results “supportive of the assumption that NDMA consumption is positively associated with [gastric and colorectal cancers].”

The WHO has categorized NDMA as a probable carcinogen.

What Are the Dangers of Valsartan?

The Food and Drug Administration (FDA) announced that the presence of NDMA in Valsartan drugs was “unexpected” and related to changes in how the active substance appeared in the manufacturing process.

Since about 2012, when generic drugs by pharmaceutical companies became available, the China-based Zhejiang Huahai Pharmaceuticals Co. had manufactured most of the wholesale Valsartan sold to drug companies worldwide.

Zhejiang Huahai Pharmaceuticals company generated $50 million from the drug in 2017.

In 2018, Zhejiang notified regulators that NDMA residue had been discovered in many of its products, including batches of Valsartan. The Valsartan contamination was extensive.

Moreover, many contaminated tablets containing NDMA were found in products made by several other wholesale Valsartan manufacturers in China and India.

Safety Warnings

In July 2018, the FDA announced a safety warning to alert patients, healthcare professionals, and the public of a voluntary recall of Valsartan because of the chemical’s probable carcinogenic effects because it was contaminated with NDMA.

Only Valsartan, sold exclusively by US companies, was affected, and the FDA asked those companies to take immediate action to protect patients.

Companies that have been found to have contaminated Valsartan include Solco Healthcare, Teva Pharmaceuticals, and Major Pharmaceuticals. Later, however, other companies would be added to the NDMA contamination list.

Before the FDA pulled the dangerous products with severe side effects from the marketplace, twenty-two other countries had already recalled Valsartan products, including Canada, Taiwan, Hong Kong, and China.

The FDA discovered an NDMA carcinogen in some recalled products: N-nitrosodiethylamine (NDMA), which cancer researchers use to induce liver tumors in laboratory animals.

Which Blood Pressure Medicine is Linked to Kidney Cancer?

The US company Torrent Pharmaceuticals produced Valsartan drug products contaminated by toxic chemicals.

Torrent and several other pharma companies later issued a voluntary recall of some of their Losartan potassium products due to problems during the manufacturing processes.

The product was pulled due to “unacceptable” levels of NDMA as an active ingredient Valsartan and other blood pressure medications manufactured by Hetero Labs Ltd. Losartan is a generic drug similar to Valsartan, is used to treat high blood pressure and heart failure.

What Kind of Cancer Can Valsartan Cause?

In 2018, a Danish paper revealed the risk of developing cancer after exposure to NDMA found in contaminated Valsartan medications.

A study involving over 5100 Danish patients without any historical familial or individual cancer cases. The study lasted nearly 5.5 years.

The study’s results did not show an increased overall risk of developing cancer in the short term when exposed to products containing NDMA-contaminated Valsartan.

However, there was uncertainty “about single cancer outcomes, and studies with longer follow-up are needed to assess long-term cancer risk.”

Is All Valsartan Affected by a Recall?

The FDA recommends that patients contact their healthcare providers to determine if the medication they are currently taking has been recalled.

However, it is imperative not to discontinue taking it until their doctor has prescribed a replacement because the drug may be treating a severe medical condition that could worsen if stopped.

The government administration releases and updates the list of recalled tainted drugs that contain NDMA, including those manufactured by Torrent Pharmaceuticals Ltd and Teva Pharmaceuticals Industries Ltd. Find the manufacturer’s name on your prescription bottle to determine if your medication was recalled.

If you can’t locate it, contact your pharmacist, who can assist you in identifying the drug manufacturer. If your Valsartan medication has been recalled, contact your doctor and discuss alternative treatment options.

Your physician might prescribe another drug or a brand of Valsartan or Losartan that is not part of the recall.
