Batches of Valsartan and similar blood pressure medications manufactured in China and India were found to be contaminated with carcinogenic chemicals that are known to cause cancer or liver damage in users.

Hundreds of products containing Valsartan, a popular drug for treating high blood pressure and heart failure, have been recalled in more than 20 countries due to impurities in the medications that are linked to cancer and other serious medical problems. The recalled Valsartan pills were manufactured overseas in China and India, and the unexpected contamination with carcinogenic impurities is believed to be due to changes a major Chinese manufacturer made to the way the drug was made. According to reports, these manufacturing changes were made as far back as 2012, which means the recalled Valsartan-containing products may have contained these impurities for years. If you or a loved one has developed stomach cancer, colorectal cancer, pancreatic cancer, liver failure or another serious medical issue while taking contaminated Valsartan, contact an experienced Valsartan injury lawyer as soon as possible to discuss the possibility of pursuing compensation through a product liability lawsuit.

Why We Think the Drug Makers Should Be Held Liable for Valsartan Side Effects

Patients who took contaminated Valsartan pills are now filing lawsuits against the drug companies and pharmacies who made and sold the defective medications. Plaintiffs in the Valsartan lawsuits are seeking compensatory damages for their injuries and pain and suffering, in addition to punitive damages to punish the drug manufacturers, distributors and retailers for negligently selling dangerous drugs containing cancer-causing chemicals. Valsartan lawsuits allege that:

  • The drug companies lied about the safety and effectiveness of their medications
  • Patients were misled and never would have bought the medications if they knew they were contaminated
  • The medications were defectively manufactured
  • The manufacturing companies failed to recognize problems with the manufacturing of their medications
  • Patients were exposed to cancer-causing chemicals by taking their Valsartan medications
  • The contaminated Valsartan drugs are worthless and not fit for human consumption
  • The drug manufacturers, distributors and retailers engaged in fraud
  • The companies were negligent in failing to warn patients about the contaminated Valsartan medications
  • The FDA failed to recall the contaminated Valsartan drugs until after 22 other countries announced Valsartan recalls.

What should you do? If you have experienced cancer, liver damage or other side effects, you should contact a lawyer as soon as possible to discuss filing a Valsartan injury lawsuit.

Exposure to toxic chemicals found in recalled Valsartan products could increase patients’ risk of developing cancer of the liver, kidney, colon, stomach or gastrointestinal tract, among other serious illnesses, and if you have been exposed to contaminated Valsartan, you should discuss your treatment with your doctor right away. If you developed cancer or suffered liver damage while taking Valsartan or another angiotensin II receptor blocker, you should contact a knowledgeable Valsartan injury lawyer to discuss your legal options. You may have grounds to file a Valsartan lawsuit against the company that manufactured, promoted, marketed and sold the contaminated medication, and our consumer advocates at the Consumer Justice Foundation can help.
