Valsartan Lawsuit Updates
Potential Settlement Reached in Irbesartan Litigation, Valsartan Claims Continue
Plaintiffs have reached a potential settlement with Aurobindo and other manufacturers, resolving claims that the blood pressure drug irbesartan caused cancer due to NDEA contamination. While Aurobindo continues to deny liability for similar valsartan claims, this development is a positive sign for the broader litigation. Individuals who were diagnosed with cancer after taking a contaminated batch of valsartan may still be eligible to file a claim and seek compensation.
Key Daubert Hearing to Determine Admissibility of Expert Testimony in Valsartan Litigation
A pivotal Daubert hearing is scheduled in the Valsartan multidistrict litigation to assess the reliability of proposed expert testimony. Plaintiffs' medical experts will present opinions linking NDMA contamination in the blood pressure medication to patient cancers. The presiding judge will evaluate the scientific soundness of these opinions from both sides to decide if they can be presented to a jury during upcoming bellwether trials. Consumers who developed cancer after taking Valsartan may still be eligible to join this active litigation by consulting an attorney to file a claim.
Valsartan Litigation Advances as Parties Clash Over Evidence in Trial Preparations
Trial preparations are intensifying in the Valsartan multidistrict litigation, with both parties actively engaging in expert interviews, discovery requests, and motion practice. Defendants have filed multiple motions to exclude evidence favorable to plaintiffs, who have lodged formal objections. The court will soon hear arguments and rule on these disputes. Individuals who developed cancer after taking Valsartan may still be eligible to file claims and seek compensation.
Valsartan MDL Grows to 1,325 Plaintiffs as Cancer Claims Mount Against Contaminated Medications
The Valsartan multidistrict litigation (MDL 2875) now encompasses 1,325 active plaintiffs, reflecting a significant influx of new cases between May and June 2025. Plaintiffs allege they developed cancer after taking generic blood pressure medications (Valsartan, Losartan, Irbesartan) contaminated with the carcinogen NDMA (N-Nitrosodimethylamine). The litigation targets drug manufacturers for failing to prevent NDMA contamination during production, which plaintiffs claim caused cancers including liver, stomach, and colorectal. As diagnoses linked to tainted medications continue to emerge, further filings are anticipated. The MDL’s growth underscores escalating liability risks for manufacturers and mounting demand for victim compensation.
About The Valsartan Lawsuits
People across the nation are joining class action lawsuits—and filing individual complaints—after taking valsartan-containing drugs contaminated with potentially carcinogenic (cancer-causing) chemicals.
Valsartan is a generic drug that, for years, was regarded as a safe and effective treatment for high blood pressure, kidney disease, and heart failure. However, a flawed manufacturing process led to hundreds of batches of the medication being contaminated with N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA), probable human carcinogens.
Though the catastrophic error was discovered and the drugs were recalled in 2018, the process causing the contamination had been used since around 2012—meaning countless patients were exposed prior to the recall.
If you or a loved one took a valsartan-containing medication between 2012 and 2018 and developed cancer or another serious illness, you may be eligible to take legal action. Those who took the drug but do not have cancer may still qualify to join a class action lawsuit. Read on to learn more.
What Is Valsartan?
Valsartan is an active ingredient used in many prescription drugs. It is classified as an Angiotensin II Receptor Blocker (ARB) and is intended to treat high blood pressure (hypertension) and heart failure. Patients may be prescribed the drug to improve survival following a heart attack, and it may also be used to protect the kidneys in certain patients.
Brand-name drugs containing valsartan include:
- Byvalson
- Diovan (single-ingredient)
- Diovan HCT
- Entresto
- Exforge
- Exforge HCT
- Prexxartan (single-ingredient)
- Valturna
- Vyduo
Many generic drugs also contain valsartan, including ones that were recalled for NDMA and NDEA contamination:
- Amlodipine and valsartan
- Amlodipine, valsartan and hydrochlorothiazide (HCTZ)
- Valsartan and hydrochlorothiazide (HCTZ)
- Valsartan
Why Is Valsartan Dangerous?
Though, like any drug, valsartan can cause side effects, the medication itself isn’t known to pose a cancer risk. Instead, the dangers arose from a faulty manufacturing process employed by China-based manufacturer Zhejiang Huahai Pharmaceutical, a company named in the lawsuits.
Around 2012, Zhejiang Huahai Pharmaceutical began producing valsartan using a sodium-azide-based synthesis to cut costs and improve manufacturing efficiency. Disturbingly, this method resulted in chemical reactions that formed probable carcinogens NDMA and NDEA.
In a display of true negligence, Zhejiang Huahai Pharmaceutical did not discover the contamination until mid-2018, when a routine quality test revealed the presence of NDMA (further tests also detected NDEA). They reported their findings to regulatory agencies like the FDA, resulting in the agency’s widespread recalls of valsartan-containing drugs beginning later that year.
Sadly, by that point, numerous contaminated batches of valsartan had already been distributed to and consumed by unknowing patients—likely for years.
Though each contaminated dose contained only small amounts of NDMA or NDEA, the risk to patients is still great since valsartan is frequently used in maintenance drugs intended to be taken routinely (often every day). This means that patients who took contaminated valsartan over an extended period may have been exposed to hazardous levels of carcinogens, increasing their cancer risk—and, in some cases, even causing them to develop cancer.
Who Qualifies For The Valsartan Lawsuits?
Eligibility for the valsartan lawsuits depends on several requirements. You may qualify to join if:
- You took a contaminated valsartan drug for at least six months between 2012 and 2018.
- You later developed cancer or other serious health problems confirmed by medical records to be linked to valsartan.
Additionally, you must meet the following requirements:
- You took one or more contaminated valsartan drugs (valsartan, valsartan + HCTZ, valsartan + amlodipine, or valsartan + HCTZ + amlodipine), and
- You used the valsartan drug(s) for at least six months prior to your cancer diagnosis.
You may also qualify if you've developed cancer(s) such as the following:
- Colorectal cancer
- Esophageal cancer
- Intestinal cancer
- Leukemia
- Liver cancer
- Multiple myeloma
- Non-Hodgkin lymphoma
- Pancreatic cancer
- Prostate cancer
- Small intestine cancer
- Stomach cancer
- Kidney cancer
- Bladder cancer
The best way to determine your eligibility to bring an individual lawsuit or join a class action is by speaking with a qualified attorney.
How To Know If You Took Contaminated Drugs?
Though some generic valsartan-containing drugs were contaminated with NDMA and NDEA and later recalled, not all medications or batches were affected. You can find out if your medication was recalled by utilizing the FDA’s Angiotensin II Receptor Blocker (ARB) recall page. Note that certain other ARB drugs, including losartan and irbesartan, have also been recalled due to contamination.
Here’s how to use the FDA’s recall page:
- Open the FDA recall page here.
- Look at your medication label, which lists the drug name, dosage, manufacturer, National Drug Code (NDC), expiration date, and lot number.
- Search for your medication by typing one of the identifiers you found on the label into the recall page’s “Search” bar (i.e., “Camber Pharmaceuticals, Inc.”).
- Compare the rest of the information on the recall page entry with the drug information from your label to ensure it matches.
If you still have questions, your pharmacist should be able to verify if your medication was part of the recall. You can also contact the FDA’s Division of Drug Information (DDI) for verification and more information.
If you did take a recalled ARB medication, you may consider speaking with a qualified attorney, who can inform you of your legal rights. We recommend filling out the form at the top of this page to request a free case evaluation from an attorney in our network.
What Do The Lawsuits Allege?
The valsartan lawsuits make serious allegations against numerous drug manufacturers and distributors, such as:
- Zhejiang Huahai Pharmaceuticals
- A-S Medication Solutions LLC
- Aurobindo Pharma
- AvKARE Inc.
- Bryant Ranch Prepack Inc.
- Hetero Labs
- Major Pharmaceuticals
- Mylan Pharmaceuticals

- Neglected to warn patients and doctors of the risks of the faulty drugs
- Failed to include a comprehensive list of ingredients on drug labels
- Falsely advertised and deceptively marketed their medications to increase profits without regard to patient health
Larry Tack is one such patient who filed a valsartan lawsuit. He began taking the drug in April 2015 to help treat his high blood pressure, a choice he and his doctors made based on its purported benefits and seemingly reliable safety profile. Naturally believing he could trust the manufacturer and distributor information, he relied on the medication for more than two years.
Tragically, Tack was diagnosed with esophageal cancer in June 2017. He also learned he had liver cancer that September. Following the FDA’s 2018 recalls, he became convinced that valsartan had caused his cancers.
Despite the illness’s harrowing mental and physical toll, Tack was determined to seek justice, so he sought the help of an experienced legal team, who filed a lawsuit on his and his wife’s behalf. Tack’s case is still pending, and he’s hopeful that a favorable outcome will serve as a warning to large corporations that put profits over safety.
