During the past several years, several new classes of diabetic medications were introduced for clinical use, including SGLT2 inhibitors (canagliflozin, dapagliflozin and empagliflozin).
SGLT2 inhibitors prevent reabsorption of glucose in the proximal convoluted tubules in the kidney and does not alter insulin release.
A recent retrospective study (n=88) of 13 poison center data from January 2013 to December 2016 showed
49 patients were evaluated in a health care facility (HCF) with 18 admissions. Referral to HCF was more common in pediatric patients. This was likely due to unfamiliarity with a new mediation and lack of toxicity data.
Other case reports have shown higher incidence of DKA with the therapeutic use of SGLT2 vs. other classes of DM medications.
Bottom line:
Limit data is available regarding the toxicologic profile of SGLT2 inhibitors.
Based upon this small retrospective study, hypoglycemia may not occur and majority of the patient experience minimal symptoms.
