Pharmaceutical Litigation Attorney’s | Information on Fournier’s Gangrene

In August of 2018, the FDA released a Drug Safety report concerning the use of SGLT2 inhibitors for diabetes such as Invokana, Farxiga, and Jardiance. These types of drugs most commonly referred to as gliflozins block the absorption of sugar into the blood causing the patient to instead flush it out in urine. The FDA warned of rare occurrences of a serious infection in the genital area referred to as Fournier’s gangrene which is a severe flesh-eating bacterial infection of tissue under the skin near the perineum.

FDA is warning that cases of a rare but serious infection of the genitals and area around the genitals have been reported with the class of type 2 diabetes medicines called sodium-glucose cotransporter-2 (SGLT2) inhibitors. This serious rare infection, called necrotizing fasciitis of the perineum, is also referred to as Fournier’s gangrene.

According to the CANVAS study, out of 1,000 patients studied 5.9 of them had the higher risk of amputation as a result of taking Invokana. This stood in contrast to the 1,000 patients taking a placebo. Only 2.8 of patients taking the placebo had a high a risk of amputation.

A second study called the CANVAS-R, a study of the effects of Canagliflozin on Renal Endpoints in Adult Participants With Type 2 Diabetes Mellitus, was also conducted and confirmed the higher risk of amputation due to Invokana with its results as well. As a result the FDA has required the diabetes drug to carry it’s most severe label, known as the black box label, or Boxed Warning.


Additionally, the FDA states that users should, “seek medical attention immediately if they experience any symptoms of tenderness, redness, or swelling of the genitals or the area from the genitals back to the rectum and have a fever above 100.4 F or a general feeling of being unwell. These symptoms can worsen quickly, so it is important to seek treatment right away.”

It is most common for the disease to affect males in the age demographic of 50-80 years old but has been found recently to affect both men and women soon after taking Invokana, Farxiga or Jardiance. To compare, in the prior 30 years there were only 6 cases of Fournier’s gangrene identified in reviews of other antidiabetics drug classes. The treatment of Fournier’s gangrene usually involves strong antibiotics or even surgical removal of the tissue. Commonly, patients require multiple surgeries and are potentially at risk of losing their genital organs.


Lawsuits against Johnson & Johnson who is the manufacturer of Invokana contain allegations that the company was negligent in properly testing the drug, that they hid the dangers from the FDA , and that they failed to sufficiently warn patients of the very serious and dangerous side effects such as Fournier’s gangrene. Most of the claims apply to patients that suffered from the serious side effects or were hospitalized due to the use of Invokana.
