Case Information


Invokana lawsuits claim that the drug manufacturer failed to warn patients and physicians about possible side effects. Legal documents note that if the diabetes drug companies had provided adequate warnings, then physicians would have prescribed safer medications and warned their patients about the risks. Here are some of the cases:

  • September 2015: An Invokana lawsuit for $1 billion (general and special damages more than $500 million each) was filed on behalf of Canadians in Ontario. Under a request for class-action status, Rosalba Joudry v. Janssen Inc., Janssen Pharmaceuticals, Inc., Janssen Ortho LLC, Johnson & Johnson, and Johnson & Johnson Inc. involves a woman who took Invokana for 8 months and suffered kidney failure.
  • December 2015: Collie v. Janssen Research & Development LLC et al., filed in Alabama Southern District Court, alleges that the plaintiff was unaware of the serious side effects of Invokana. The patient in this case started taking the diabetes medicine a year earlier and quickly developed diabetic ketoacidosis. She claims that Janssen did not provide complete warnings about the increased risks or thoroughly study Invokana before releasing the diabetes drug in 2013. The plaintiff also alleges that Janssen improperly advertised the medication for treatment of type 1 diabetes and high blood pressure.
  • December 2015: Soon after the FDA issued an Invokana safety alert, Arthur Portnoff filed an Invokana lawsuit. The plaintiff, currently living in Texas, filed his lawsuit in the Philadelphia Court of Common Pleas because he was based in that city while taking the diabetes medication. He started taking the drug in November 2014, developed diabetic ketoacidosis and was hospitalized 3 months later. Portnoff argues that Janssen failed to conduct reliable studies about Invokana, withheld information and failed to provide proper warnings.
  • February 2016: Charles Maddox v. Janssen Pharmaceuticals Inc. et al. was filed in the U.S. District Court for the Eastern District of Louisiana. According to court records, the plaintiff took Invokana for treatment of type 2 diabetes between July 2014 and February 2015. Soon after he stopped taking the medicine, he suffer diabetic ketoacidosis, a serious and potentially life-threatening condition.
  • May 2016: A report indicated that more plaintiffs have filed Invokana lawsuits including Maria Puente and Carlos Puente v. Janssen Pharmaceuticals Inc. et al. In October 2013, Maria started taking the diabetes medicine Invokana for a month. In that short period, she suffered serious health complications including diabetic ketoacidosis and kidney damage. The plaintiff claims that she would not have taken the drug if Janssen Pharmaceuticals had supplied complete information about the dangers.
