Sodium-glucose cotransporter-2 (SGLT2) inhibitors have become a valuable addition to the arsenal of medications for diabetes management.

However, a recent study conducted by the FDA has shed light on a potential risk associated with these drugs, linking them to a rare but serious infection called Fournier gangrene. Understanding this risk is crucial for healthcare providers and patients.

SGLT2 Inhibitors: A New Approach to Diabetes Treatment

SGLT2 inhibitors are a relatively new class of medications designed to address diabetes by promoting the excretion of excess glucose in the urine. They have proven effective in helping patients manage their blood sugar levels.

The FDA study aimed to assess the safety profiles of various diabetes drugs, including SGLT2 inhibitors, metformin, insulin glargine, short-acting insulin, sitagliptin plus metformin, and dulaglutide.

The study focused on identifying any adverse effects associated with these medications.

Fournier Gangrene: A Disturbing Finding

Researchers discovered a concerning link between SGLT2 inhibitors and a rare infection known as Fournier gangrene. This severe condition can manifest in areas such as the external genitalia, perineum, and perianal region.

The study identified 55 cases of Fournier gangrene among diabetic patients who had used SGLT2 inhibitors between March 1, 2013, and January 31, 2019. The patients affected ranged in age from 33 to 87 years, with 39 being men and 16 being women.

Onset and Complications: Varied Timelines and Additional Health Issues

The onset of Fournier gangrene in these patients occurred anywhere from 5 days to 49 months after initiating treatment with SGLT2 inhibitors.

In addition to this serious infection, the affected individuals also experienced other diabetes-related complications, including diabetic ketoacidosis, sepsis, and kidney injury.

In contrast, only 19 cases of infection were identified among patients using other diabetes drugs between 1984 and January 31, 2019. This stark contrast underscores the importance of recognizing the association between SGLT2 inhibitors and Fournier gangrene.

This study reveals a previously unrecognized safety concern in diabetic patients treated with SGLT2 inhibitors.

Healthcare providers who prescribe these medications should be vigilant in monitoring their patients for signs of Fournier gangrene and other potential complications.


While SGLT2 inhibitors have offered significant benefits in managing diabetes, this study emphasizes the need for careful consideration of potential risks.

Patients and healthcare providers must weigh the benefits and potential drawbacks of these medications, making informed decisions to ensure the best possible management of diabetes while minimizing associated risks.
