Invokana has been found to cause genital gangrene in rare cases.
All users of the diabetes drug are at risk, but factors such as alcoholism, the use of cancer drugs, and having HIV increase the risk of Invokana genital gangrene.
Research has also found middle-aged patients to be more susceptible to developing genital gangrene from Invokana use.
If you’re currently taking the SLGT-2 inhibitor Invokana, ask your doctor about the risks of the drug or alternative treatments.
If you experience any new pains or side effects after starting Invokana, be sure to immediately contact your doctor right away.
If injuries persist, contact an experienced Invokana lawyer to discuss filing an Invokana lawsuit to seek compensation for your injuries.
Do All SLGT-2 Inhibitors Cause Genital Gangrene?
At least 11 different SGLT-2 drugs are prescribed to patients worldwide.
Only 3 of these SGLT-2 drugs have been scientifically linked to genital gangrene.
The drugs that have shown to cause the genital gangrene disease include:
- Empagliflozin (Jardiance)
- Dapagliflozin (Farxiga)
- Canagliflozin (Invokana)
The other diabetes drugs have not demonstrated genital gangrene as an effect, but further research could potentially prove otherwise.
Type 2 Diabetes Medication Causes Genital Infection, FDA Warns
The FDA released a public safety alert, warning type 2 diabetes patients taking SGLT-2 inhibitors that they may be at risk of developing necrotizing fasciitis of the genitals and genital area.
Necrotizing fasciitis of the genital area, also called Fournier’s gangrene, is a life-threatening flesh-eating bacterial infection of the skin surrounding the muscles, nerves, fat, and blood vessels in the genitalia.
It is most common among men ages 50 to 79 and occurs in about 1.6 of 100,000 men annually in the U.S. It is very uncommon in women.
The FDA has mandated new prescribing information and patient medication guides making SGLT-2 patients aware of the increased risk of developing Necrotizing fasciitis for the following medications:
- Canagliflozin (Invokana, Invokamet, Invokamet XR)
- Dapagliflozin (Farxiga, Xigduo XR, Qtern)
- Empagliflozin (Jardiance, Glyxambi, Synjardy, Synjardy XR)
- Ertugliflozin (Steglatro, Segluromet, Steglujan)
Invokana Necrotizing Fasciitis Adverse Events Reports
Since March 2013, the FDA has received 12 reports of type 2 diabetes patients prescribed SGLT-2 inhibitors who have developed necrotizing fasciitis of the genitalia – five women and seven men ranging from 38 to 78 years old.
All of the four SGLT-2 drug-types except ertugliflozin were included in the reports – although there have been no reports so far, the FDA stated that ertugliflozin would be expected to run an equal risk to patients.
For these individuals, the window of development ranged from 7 days to 25 months after taking SGLT-2 inhibitors with an average of 9.2 months.
All 12 individuals who reported developing necrotizing fasciitis of the genitalia were hospitalized and underwent a surgical procedure to remove the infection.
Five of the individuals underwent more than one surgical procedure.
One individual required skin grafting.
Four of the individuals dealt with post-surgical complications including diabetic ketoacidosis, acute kidney injury, and septic shock.
There was one reported death.
Two individuals were transferred to a rehabilitation hospital.
Symptoms of Genital Gangrene
Symptoms of Fournier’s gangrene include:
- Tenderness
- Redness
- Swelling of the genital area
- Body temperature exceeding 100.4 degrees Fahrenheit
If you are prescribed an SGLT-2 inhibitor to treat type 2 diabetes, and you show any signs or symptoms of Fournier’s gangrene, seek medical attention right away.
Fournier’s gangrene is a degenerating disease, worsening over time.
If caught in its early stages, Fournier’s gangrene can be treated with antibiotics – but if left untreated, a surgical procedure may be necessary.
If you are taking an SGLT-2 inhibitor to treat type 2 diabetes, talk to your doctor about the risks of your medication and whether you are eligible for other type 2 diabetic treatments.
If you are currently or were ever taking an SGLT-2 inhibitor, and as a result developed necrotizing fasciitis of the genital area / Fournier’s gangrene, contact the offices of TorHoerman Law.
You may be eligible to participate in an Invokana genital gangrene lawsuit.
Additional FDA Reports of Invokana Genital Gangrene Link
The FDA examined users of Invokana and other SLGT-2 inhibitors between 2013 and 2019 and found 55 cases of Invokana genital gangrene.
Almost 90% of cases were in men.
The FDA reported that all of the patients had to undergo immediate surgery to treat the illness.
Even patients who received proper treatment could suffer further complications such as septic shock or diabetic ketoacidosis.
Despite the rates of Invokana genital gangrene being quite low, the FDA concluded that physicians should be aware of the risks when prescribing Invokana to their patients.
