Invokana is one of the top-selling Type 2 diabetes medications in its class, and the medication is one of the first to receive additional approval from the U.S. Food and Drug Administration for use in high-risk patients to reduce cardiovascular events. Unfortunately, some patients being treated with the drug and others in its class have suffered severe adverse events. Some of these patients are working with our Invokana lawyers to hold the manufacturer accountable for these injuries and recover significant financial compensation.
Patients across the country have reached out to our Invokana injury lawyers about their legal right to make informed healthcare decisions. You see, drug manufacturers have a high legal responsibility to warn patients and their physicians about side effects, adverse events, and contraindications associated with their products. If they fail that responsibility, they can be held liable for injuries those products cause. Patients have a right to know about side effects and adverse events before they are treated with the medication so together with their doctors, they can make the right treatment decisions for their individual circumstances.
Our attorneys have represented tens of thousands of clients and negotiated and litigated billions of dollars’ worth of settlements and awards on their behalf. Our firm has been in contact with thousands of Invokana patients who are concerned about adverse events for which they were never warned. These patients are dealing with terrible injuries, and they want lawyers they can trust to help them hold Janssen Pharmaceuticals and parent company Johnson & Johnson accountable.

SGLT2 inhibitors block glucose from being reabsorbed so more is able to be removed from the body in urine. Unfortunately, Invokana and other medications in this class of drugs have been associated with severe health risks.
Invokana Adverse Events and Side Effects
Since being approved by the FDA, Invokana has been associated with a wide range of serious adverse events and side effects including those that pose life-threatening complications including deadly blood infections caused by severe urinary tract infections, acute kidney injury, above and below the knee amputations, amputations of the feet and toes, and dangerously acidic blood. The amputations risks are so great the FDA required Janssen to place a Black Box warning on the label of the drug. A letter was also issued to physicians to monitor the lower limbs of Invokana patients for sores, ulcers, and infections.
- Increased risk of amputation – FDA warned that Invokana might increase the risks of amputation in diabetic patients including toe, mid-foot, below the knee, above the knee, and amputations involving both limbs. Patients are warned to seek medical attention if they experience infections, ulcers, sores, areas of the leg or foot that are tender to the touch.
- Diabetic ketoacidosis – the FDA issued a warning for an increased risk of ketoacidosis for diabetics receiving treatment with SGLT2i medications including Invokana. This condition causes blood to become acidic which can lead to severe health consequences.
- Kidney Failure- the FDA received thousands of complaints of genital fungal infections that are so severe they are life-threatening. Clinical trial results showed that patients treated with this medication had a three to four times higher risk of developing the infection than non-users.
- Renal Injury – the FDA announced that some patients treated with Invokana developed severe urinary tract infections that progressed to life-threatening renal injury and blood infections. Some patients required dialysis or intensive medical care for renal failure.
- Bone Fractures – FDA mandated clinical trials showed Invokana could cause bone mineral density loss at the lower spine and hip resulting in an increased risk of bone fractures even during minor traumas, such as tripping over something and falling.
- Genital gangrene – Invokana and other SGLT2 inhibitors have been associated with an increased risk of developing a flesh-eating bacterial infection that causes gangrene of the genitals.
Timeline of Events
Since being approved for the market in 2013, Invokana has been at the center of a range of FDA warnings and communications including for life-threatening adverse events and side-effects. Here we list a brief timeline of events based off of FDA information and media reports.
- March 2013 – Invokana received FDA approval as a treatment for type 2 diabetes.
- March 2013 – According to the New York Times, the FDA orders post-marketing clinical trials of Invokana.
- May 2015 – FDA issues safety announcement for Invokana ketoacidosis, a condition in which blood acids called ketones are overproduced.
- September 2015 – FDA orders labels of Invokana and Invokamet to warn of bone fractures and decreased bone mineral density.
- December 2015 – FDA orders labels to warn of ketoacidosis and increased risks of serious UTI
- January 2016 – Institute for Safe Medication Practices issues report stating 5,484 Invokana adverse events had been filed.

In these warnings and communications, the FDA warns patients not to stop taking Invokana or other SGLT2i drug without speaking first with their physicians about alternative therapy.
Across the country patients who developed gangrene, renal injury, ketoacidosis, and suffered broken bones, amputations, or Fournier’s gangrene of the genitals have simply had enough. We are filing Invokana injury lawsuits on behalf of our clients who say they started treatment with Invokana and developed serious conditions and suffered severe injury. The plaintiffs in these lawsuits allege Janssens Pharmaceuticals knew or should have known about the increased risks and adverse event dangers associated with Invokana but failed to warn the medical community or its patients about these risks and dangers.
Patients across Europe, Canada, and the United States are seeking justice for injuries they say occurred after starting treatment with Invokana. Some of these patients allege they suffered amputations, ketoacidosis, gangrene or other injury within a short period of starting the medication. In fact, thousands of cases have been filed across the country, and multidistrict litigation has been established in U.S. District Court for the District of New Jersey.
Cases filed in multidistrict litigation are different than cases filed in a class action in that damages are awarded for each case and go to the individual plaintiff instead of being shared amongst the members of a class.
Patients who are filing lawsuits allege that they would not have received treatment with Invokana if they had been made aware of the dangerous adverse events that have been associated with the drug. They allege that Janssen Pharmaceuticals was negligent by failing to inform the medical community and their patients about the increased risks of suffering amputations, renal injury, ketoacidosis, and gangrene of the genitals.
