Invokana Class Action Lawsuits


If you or a loved one used the Type 2 diabetes medication Invokana and have suffered from ketoacidosis, kidney issues or amputations of the toe, foot, or leg after using Invokana, you may be eligible for financial compensation.

Due to the varied side effects and issues affiliated with taking Invokana, the lawsuits set forth diversify from physical injuries, stroke, diabetic ketoacidosis, kidney failure, amputation and even death. However, the most notable legal argument brought forth to the drug companies is the lack of information about the risks associated affiliated with Invokana. Should proper notification of the risks have been administered; patients could have chosen an alternative drug treatment for to treat their Type 2 diabetes. 

With the additional FDA black box (highest level) warning concerning the risks of Invokana, it is expected additional lawsuits will be filed. If you have taken Invokana and suffered any adverse side effects, you may be entitled to compensation.  To speak with an experienced Michigan Attorney at our firm, or acquire a free, no-obligation consultation, call

Sodium-glucose contransporter-2 (SGLT2) inhibitors, such as Invokana (canagliflozin), are a category of drugs that treat low blood sugar in adults with Type 2 diabetes.  The U.S. Food and Drug Administration has issued warnings that taking SGLT2 Type 2 diabetes medications may have several adverse side effects. Most recently (2017), a black box warning (the highest level safety alert issued by the FDA) was released for patients taking Invokana. Although the FDA disclosed the risks associated with SGLT2 inhibitors like Invokana, affected individuals argue that Janssen Pharmaceuticals (a subsidiary of Johnson & Johnson) did not properly disclose the risk of the medication and failed to inform patients about the adverse side effects. 

Some users of Invokana have suffered side effects that required hospitalizations, where others have been permanently disabled. Due to these devastating medical crises, users of the drug have opted to take legal action against the makers of Invokana (Janssen Pharmaceuticals and Johnson & Johnson).


Side effects include the onset of diabetic ketoacidosis (DKA) which is related to excessive acid levels (ketones) in the blood and is characterized by trouble breathing, nausea, vomiting, abdominal pain, confusion or difficulty concentrating unusual fatigue or sleepiness, dry or flushed skin.

Kidney injuries or impaired function have also been associated with taking Invokana. Specifically, side effects may include kidney failure or impairment, dehydration/fluid imbalances, kidney stones, urinary tract infections, as well as abnormal weight loss. The kidneys serve the key functions of filtering waste products from the blood, assist with controlling blood pressure, balance electrolytes, as well as red blood cell production. Improper function of the kidneys can result in increased weakness, lethargy, confusion, weakness, and abnormal heart rhythms and even death. 

Increased likelihood of bone fracture and more concerning leg, foot or toe amputations are also associated with taking Invokana.  Risks are twice that of people taking Invokana compared to regular patients taking a placebo. Patients experiencing a higher level of tenderness, sores, ulcers, and/or infections in their legs or feet should contact a medical professional immediately.
