Cutaneous Adverse Drug Reactions Associated with SGLT2 Inhibitors

Diabetes is a complex global healthcare burden involving multiple organ systems with its prevalence on the rise. SGLT2 inhibitors enhance glucose excretion. The objective of our literature review was to determine the association between cutaneous adverse drug reactions (CADRs) and the use of SGLT2 inhibitors. We collected data on CADRs related to the use of SGLT2 inhibitors from all available published articles and studied their details to understand the patterns of their association. PubMed, Cochrane, Google, and Embase were searched for relevant articles. A total of 37 papers were included and studied. Most articles were case reports followed by pharmacovigilance studies, case series, and reviews. The cutaneous findings ranged from benign eruptions to severe reactions. The available literature suggests a strong link between the use of SGLT2 inhibitors and Fournier's gangrene/necrotizing fasciitis. T2DM patients using SGLT2 inhibitors have also developed fixed drug eruptions, drug-induced pruritus, and Sweet syndrome/acute febrile neutrophilic dermatosis, among other skin lesions. We found that SGLT2 inhibitors present a risk of developing CADRs. Raising awareness among healthcare providers regarding CADRs to SGLT2 inhibitors can reduce complications, minimize hospitalizations, and improve patient care in the vulnerable population of diabetes patients.
