A couple has filed a lawsuit against Janssen pharmaceuticals and parent company Johnson & Johnson as well as Mitsubishi Tanabe Pharma Corp. alleging the companies’ drug Invokana induced heart attack, ketoacidosis and other physical conditions.

Plaintiffs Crystal and Lee E. allege that Crystal’s injuries were caused as a direct result of the defendants’ “negligent and wrongful conduct in connection with the design, development, manufacture, testing, packaging, promoting, marketing, distribution, labeling, and/or sale of Invokana for the treatment of diabetes.”

Crystal began using Invokana in March 2014 and stopped taking the diabetes medication in October 2014.

While Crystal did not suffer an Invokana induced heart attack, she did suffer from diabetic ketoacidosis, according to the lawsuit.

Diabetic ketoacidosis is a condition where too many ketones build up in the blood, causing the blood to become very acidic. The body must remain in a fairly neutral state, and when it is to acid or alkaline, severe problems can result.

In the case of diabetic ketoacidosis, the body’s acid state becomes problematic.

Invokana is a member of a class of pharmaceuticals known as sodium-glucose code transporter 2 inhibitors, more commonly known as SGLT2 inhibitors. The medication works by inhibiting glucose reabsorption into the kidneys, thereby lowering blood glucose.

According to the lawsuit, Invokana is one of the top selling drugs for the defendants, with sales equaling $278 million in the first quarter of 2015, just two short years after it was released.

The lawsuit states that Invokana induced heart attack and other physical problems, yet proper warnings were not given. “The warnings that were given by Defendants failed to properly warn physicians of the increased risks of permanent physical injuries including, but not limited to, diabetic ketoacidosis, stroke, heart attack, and severe kidney damage.”

Crystal states that she would not have used Invokana if the manufacturers would’ve disclosed the risks associated with the drug.

As a result of ingesting the allegedly dangerous drug, Crystal “suffered severe and permanent physical and emotional injuries” including having endured “pain and suffering, emotional distress, loss of enjoyment of life, and economic loss, including significant expenses for medical care and treatment which will continue in the future.”

Additionally, the lawsuit states that Crystal also suffered from mental anguish do to her knowledge that she may continue to suffer and have lifelong complications as a result of the injuries she sustained allegedly by her ingesting Invokana.

The couple has filed a lawsuit against the defendants on several counts including manufacturing defect, defective design, failure to warn, breach of express warranty, negligence, breach of implied warranty, fraudulent misrepresentation, negligent misrepresentation, fraudulent concealment, fraud and punitive damages.

Crystal and Lee are seeking judgment against the defendants as well as compensatory damages, medical expenses and other economic damages, damages for pain and suffering and loss of consortium (spousal companionship), noneconomic damages, punitive damages and attorneys’ fees and costs.

They are requesting a trial by jury.

Other lawsuits have also been filed against the manufacturers alleging that Invokana induced heart attack, kidney failure, diabetic ketoacidosis and stroke and the plaintiffs are seeking damages.

The Invokana Induced Heart Attack Lawsuit is Case No. 3:16-CV-05478, in the U.S. District Court for the District of New Jersey, Trenton Division.
