The usage of Diovan had no evidence of any adversity in its entire span, but the FDA did find that the generic versions of Valsartan were causing issues. The most serious issue reported was that it had the presence of an impurity called N-Nitrosodimethylamine (NDMA), which was believed to be formed as a byproduct through a chemical reaction. Not only was this an impurity, but a concern was also raised when it was detected that NDMA is carcinogenic and can lead to cancer in people consuming this drug for the long term.

Immediately, the FDA called for its largest recall of Class I drug, Valsartan on 13 July 2018. The following manufacturers recalled their Valsartan containing drugs.

Recalled Products:

Medicine Company Valsartan - Major Pharmaceuticals

Valsartan - Solco Healthcare

Valsartan - Teva Pharmaceuticals Industries Ltd

Valsartan/Hydrochlorothiazide (HCTZ) - Solco Healthcare

Valsartan/Hydrochlorothiazide (HCTZ) - Teva Pharmaceuticals Industries Ltd

The exact nature of injuries and its effects on the human body is still being studied to derive any strong conclusions. Meanwhile, patients consuming these generic drugs and facing injuries are advised to come ahead.

Along with Valsartan, there are other generic drugs belonging to the same class which can come under the FDA radar due to similar issues, which are:

  • Irbesartan (Avapro)

  • Losartan (Cozaar)

  • Olmesartan (Benicar)

  • Candesartan (Atacand)

These above drugs are suspected to cause similar injuries because they share the same manufacturing process as that of Valsartan.

Serious Alleged Injuries May Include:

  • Stomach Cancer
  • Liver Cancer
  • Colorectal Cancer
  • Lymphoma
  • Esophageal Cancer
  • Bowel Cancer
  • Liver Failure
