Many medications using the ingredient valsartan have been the subject of voluntary recalls since 2018 due to an NDMA contamination at the manufacturing level that started in 2012.
The Sadaka Associates is available to represent those who believe they’ve purchased or used drugs tainted by this negligence and want just and fair compensation.
Read more to learn about valsartan, the massive litigation against its manufacturers, and how Sadaka Associates can help you.
WHAT IS VALSARTAN?
Valsartan is an oral medication most used to treat high blood pressure and heart failure. It can be sold under a variety of trade names and is also available in generic forms. It is also an oral medication most commonly used as a central component for drugs prescribed to treat diabetes-related kidney diseases, high blood pressure, and heart failure. Valsartan is sold as Valsartan and several names, such as, Diovan, Byvalson, Entresto, Exforge, and Valturna.
Valsartan was introduced to the market in the mid-90s and has been sold consistently since then.
Valsartan is what’s known as an angiotensin II receptor blocker, or ARB. It functions by blocking the hormone responsible for constricting blood vessels throughout the body. Doing so prevents blood pressure from rising, alongside other benefits.
This function makes valsartan a popular ingredient in blood pressure medications. According to the Center for Disease Control, 30 million adults take blood pressure medication. It’s safe to assume that most of them are regularly consuming valsartan as a result.
Dosages vary based on intended treatment as well as age. It’s currently manufactured in tablet form, in four sizes: 40 mg, 80 mg, 160 mg, and 320 mg. It’s rare for doctors to prescribe 320 mg doses because valsartan poses an overdose risk.
VALSARTAN AND NDMA
In 2018 the European Medicines Agency discovered impurities in certain drugs using valsartan and began a recall. Initially, they found batches of valsartan contaminated with NDMA shipped to European countries and Canada.
As the EMA tested valsartan products, they found the active ingredient, manufactured by Zhejiang Huahai Pharmaceuticals of China, contaminated by NDMA, an organic compound known to be carcinogenic.
The American Food and Drug Administration followed in the EMA’s footsteps almost immediately. During extensive laboratory testing and research, the FDA confirmed valsartan shipped to the United States had been contaminated as well, not only with NDMA but NDEA (a weaker carcinogenic compound) as well. As the FDA began naming specific manufacturers selling medication that tested positive for NDMA, recalls began.
Currently, the FDA believes contamination to have begun in 2012 when Zhejiang Huahau Pharmaceuticals altered their manufacturing process.
As one of the largest valsartan manufacturers globally, their valsartan has been purchased by over thirty companies and used in many more medications under different brand names and generic forms. With blood pressure medications being commonplace, especially in North America, it’s believed that exposure to NDMA is potentially widespread.
At present, the FDA has not issued a recall notice for drugs containing valsartan. However, many companies have participated in a voluntary recall of their products that include the compound. It’s not currently known if the FDA will mandate a recall, but their research and testing are ongoing.
While not requiring drug companies to recall medications with valsartan, the FDA maintains and regularly updates a list of recalled products. You can view that list on the FDA’s website here. The administration also posts updates, including other manufacturers creating valsartan with impurities, here.

VALSARTAN INJURIES AND SIDE EFFECTS
Under ordinary circumstances, valsartan has potential side effects that patients need to monitor for their wellbeing. These side effects vary depending on the medication prescribed to them. The dosage could also be a factor. As with all drugs, valsartan can have harmful interactions with other medicines you take.
When used as a heart failure treatment, side effects include dizziness, diarrhea, joint and back pain, and low blood pressure. Of these side effects, dizziness is the most common and affects less than 17% of patients. The other side-effects occur much less frequently and aren’t as severe.
As a treatment for hypertension and high blood pressure, many of the same side effects are present. In addition to these, flu-like symptoms, such as abdominal pain, may be present. However, all of these are incredibly uncommon when compared to their presence in other treatments.
Lastly, valsartan and other ARBs used to treat kidney failure can worsen renal failure and heart failure symptoms. A dosage that’s too high or taken too frequently can cause a bodily response to constrict blood flow in an attempt to direct more blood to the kidneys. These are the most severe complications valsartan can produce and require close monitoring by both the patient and their healthcare professional.
Valsartan is one of many drugs to come with a black box warning. A black box warning establishes when drugs pose a serious threat to a fetus. This threat is a natural consequence of the drug, so pregnant women should never take it.
The NDMA contamination has added much more severe risks. Nitrosodimethylamine NDMA sometimes causes liver damage, including tumors and cirrhosis, in laboratory rats. Based on this, scientists believe NDMA is a human carcinogen as well.
NDMA can occur naturally in low doses, but higher doses pose a health risk. NDMA appears as part of the water treatment process. The Environmental Protection Agency has established an acceptable level of concentration, and local authorities constantly analyze their water to ensure it’s within safe limits.
Once NDMA is present in a water source, you must treat it differently as it isn’t easy to filter out. There are also increasing concerns with NDMA entering our environment in other ways. For example, burning rocket fuel at test sites leads to the compound developing in groundwater.
WHY WAS VALSARTAN RECALLED?
Recalls worldwide have taken place because the FDA, the EMA, and other medical bodies have discovered NDMA in valsartan manufactured by the world’s largest supplier. As authorities continued investigating the contamination, they found other pharmaceutical companies producing ARBs like valsartan with the same contamination.
The voluntary recalls are happening in the United States and worldwide because NDMA can cause cancer in humans based on animal testing. Officially, the EPA classifies the compound as a possible carcinogen based on laboratory tests. NDMA has even been used to intentionally poison people in the past.
Zhejiang Huahai Pharmaceuticals, the first identified source of the contamination, was the leading producer of valsartan in the world. The FDA believes that when ZHP changed their manufacturing process in 2012, they accidentally created NDMA as a by-product, adding it to the drug. This mistake appears to have gone unnoticed until EMA and FDA testing confirmed the contamination.
In wanting to produce valsartan in more significant quantities faster, ZHP changed some of the process’s chemicals. However, the new combination had the side-effect of creating NDMA.
Dangerous methods like these were found in another manufacturer, Hetero Labs in India, and have renewed the FDA’s focus on drugs made outside of the United States. Unfortunately, they don’t have much control over how foreign companies do business.
Since tracing valsartan back to ZHP and Hetero Labs and connecting them with companies worldwide, the FDA has worked to identify which products are likely contaminated and pose a danger to the public. Over fifty companies have since recalled affected products from the market.
Similar NDMA contaminations appeared in other drugs since 2012. The popular over-the-counter heartburn treatment Zantac underwent a recall in 2019 when independent testing revealed contamination. Some valsartan products sold by Teva Pharmaceutical, Solco Healthcare, and other companies have suffered from flawed production.
Consumers should note that while the recalls for specific drugs aim to remove them from the market entirely, only portions of the drugs produced starting in 2012 are known to be affected.
Similarly, not all medicines containing valsartan have been subject to recall. Those that secured their ingredients from sources that tested safe remain for sale.
STATUS OF VALSARTAN LITIGATION
Lawsuits against the tainted drug manufacturers and sellers started shortly after the FDA announced the faultiness in 2018. Some of the litigants had developed ill-health during the time the manufacturing took place. Others don’t show signs of illness. But because they took the tainted medicine, users believe they were at risk.
As of this writing, all of these valsartan lawsuits have been joined together into a multi-district lawsuit. It is similar to a class-action lawsuit in that all of the plaintiffs are collectively suing the defendants. However, the case each person brings is resolved individually on a case-by-case basis rather than as one judgment or settlement.
A few individual suits from the multi-district lawsuit will be allowed to go forward with their trials first (these initial trials in multi-district litigation are sometimes called bellwether trials). This trial will play out as any ordinary trial would and follow the same processes. The results from these cases cause both sides to either settle or litigate the remainder of the lawsuit.
The bizarre nature of the contamination and its discovery has given litigants various reasons to file a valsartan recall lawsuit. The most common so far appears to be personal injuries, where plaintiffs suffered physical harm resulting from taking the defective products. Others are suing for monetary damages stemming from the loss of work or medical bills and wrongful death.
Whether or not any specific case will succeed can’t be known beforehand. However, the nature of multi-district lawsuits means that individual litigants aren’t bound to each other’s success as a group.
Given the widespread use of medications with valsartan and how long it takes for litigation to move forward, the number of plaintiffs will likely grow.
While many litigants have come forward with their complaints, the underlying thread they have in common is that the involved pharmaceutical companies ignored the risky procedures used by ZHP and Hetero Labs.
Those two manufacturers stand accused of ignoring warnings from the FDA regarding their manufacturing practices. This litigation’s ultimate goal is to resolve these issues and compensate consumers harmed by this negligence.
WHAT TO EXPECT WHEN FILING A LAWSUIT
If you intend to file and join the valsartan recall lawsuit against manufacturers and sellers of valsartan, the first thing you should know is that you have a limited time to do so. Each state has a statute of limitations that establishes how long you have to file a lawsuit, regardless of the reason for the suit. It’s always best to file your case as soon as possible to ensure it falls within the legal time limit.
Before filing, your lawyer will ask you a series of questions to determine whether or not they think you have a case and how strong it is. They’ll need to know how long you’ve been taking the medication and what medical problems it has caused you. You’ll need to present evidence supporting each claim, so be prepared with relevant records.
You should also expect a lot of waiting while the lawsuit goes forward. It’s rare for a case to quickly work its way through the courts, let alone one with so many plaintiffs and defendants. It can take years for a suit to start and reach a conclusion.
Throughout this waiting period, your lawyer will be in contact with you with updates. Likewise, you should reach out to them if your condition changes. Constant communication between you and your legal team is essential to staying abreast of the situation as it unfolds.
After the bellwether trials conclude, the remainder of the multi-district litigation begins. The plaintiffs serve as one group and all the defendants as another. Usually, the initial trials’ results will promote defendants to settle rather than continue expensive litigation, but that’s not always the case.
WHO CAN FILE A LAWSUIT
There are standards in place that you have to meet to be eligible to sue in this case. Simply taking valsartan alone is enough to qualify your case. The currently established standards require that those with injuries need to have taken a drug containing valsartan manufactured or sold from one of the named defendants for at least a year with a specific illness or damage resulting from use.
Though studies have shown that NDMA can cause cancer in laboratory mice, confirmed studies on the impact it has on humans are few and far between. The studies that do exist point towards the compound impacting the liver, gastrointestinal tract, and digestive organs. If you were diagnosed with cancer of the liver, stomach, bladder, colon, rectum, liver, pancreas, or kidneys, you might qualify.
However, your diagnosis has to have come one year after you started taking valsartan for your claim to be valid. It doesn’t matter if you medicated consistently during this time so long as you took it for at least thirty days. The dosage and frequency of use are non-factors in determining your eligibility.
Finally, the medication you took must have been sold or made by one of the identified companies and been part of one of the affected lots. These requirements are in place to prevent people from lawsuits against pharmaceutical companies that didn’t use contaminated valsartan.
All of this needs to have occurred from 2014 onward. Other forms of injury may qualify, but it is on a case-by-case basis. Speak with your lawyer if you’re unsure you are eligible, and they’ll assist you.
COMPENSATION FOR VALSARTAN INJURY LAWSUITS
All the law firms representing the numerous plaintiffs in the valsartan lawsuit are working together for their clients’ shared goals. They ultimately seek the defendants to cover all medical costs, compensation for pain, suffering, lost wages, and out-of-pocket costs related to taking the drug, injuries, and legal expenses.
Should settlements be reached, awards are delegated on an individual case-by-case basis.
That said, litigation is still in the very early stages, and anything could happen. Usually, the bellwether trials’ results allow attorneys to gauge the likelihood of different outcomes, including settlement negotiations, but that isn’t always the case.
Even though the defendants are successful pharmaceutical companies, that isn’t indicative of what they are willing to pay in a settlement, should a settlement be reached.
