Hello,
Yes, there has been a class action lawsuit filed in New Jersey regarding the drug Valsartan-HCTZ. A federal court in New Jersey has approved a class action lawsuit against several manufacturers of generic Valsartan after the discovery of contamination with cancer-causing chemicals known as nitrosamines. As of February 2023, all federal court proceedings associated with these lawsuits have been consolidated into the Valsartan MDL class action, which is now underway in New Jersey.
I hope the information may helps you.
