The most commonly reported adverse events have included genital mycotic infections, more common in females, but also occurring in males.[Ref]


Very common (10% or more): Female genital mycotic infections (up to 12.2%)

Common (1% to 10%): Male genital mycotic infections, urinary tract infections, vaginal pruritus, increased urination

Frequency not reported: Pyelonephritis

SGLT2 Inhibitors:

Postmarketing reports: Serious urinary tract infections including urosepsis and pyelonephritis, Fournier's gangrene[Ref]

Female genital mycotic infections include genital candidiasis, genital infection fungal, vaginal infection, vulvitis, vulvovaginal candidiasis, vulvovaginal mycotic infection, and vulvovaginitis. Male genital mycotic infections balanitis candida, balanoposthitis, genital infection, and genital infection fungal. Urinary tract infections include cystitis, dysuria, streptococcal urinary tract infection, urethritis, urinary tract infection. Vaginal pruritus includes vulvovaginal pruritus and pruritus genital. Increased urination includes pollakiuria, micturition urgency, polyuria, urine output increased, and nocturia.

In the 5 years (2013 to 2018) since SGLT2 inhibitor approval, 12 cases of Fournier's gangrene have been reported. Reports were almost equal in men and women (men=7; women=5), ages ranged from 38 to 78 years, and the average time to onset after starting an SGLT2 inhibitor was 9.2 months (range 7 days to 25 months). All SGLT2 inhibitor drugs except ertugliflozin were included in the reports. Ertugliflozin being the most recently approved agent, is expected to have the same risk, but insufficient patient use to assess risk. All patients were hospitalized, all required surgery, all required surgical debridement, 5 required more than 1 surgery and 1 required skin grafting. Four cases were complicated by diabetic ketoacidosis, acute kidney injury, and septic shock, leading to prolonged hospitalization, and death in 1 case. In the general population, Fournier's gangrene occurs in about 1.6 out of 100,000 males annually, with the highest incidence in men 50 to 79 years. Since diabetes is a risk factor for Fournier's gangrene, a review of the FAERS database for the last 34 years was done and only 6 cases (all males, median age 57 years) were found with several other classes of antidiabetic drugs. Findings with SGLT2 inhibitors appear to show an association over a shorter time frame and involve both males and females.[Ref]


Nontraumatic lower limb amputation was reported in 3 (0.2%) patients receiving 5 mg and 8 patients (0.5%) receiving 15 mg; there was 1 report (0.1%) in the comparator group. A causal association between this drug and lower limb amputation has not been definitively established.

Common (1% to 10%): Back pain

Uncommon (0.1% to 1%): Nontraumatic lower limb amputation


Ketoacidosis was reported in 3 of 3409 (0.1%) patients treated with this drug during clinical trials; no cases were identified in comparator-treated patients.

Very common (10% or more): Hypoglycemia (in combination with insulin and/or insulin secretagogue in patients with moderate renal impairment; up to 27%)

Common (1% to 10%): Decreased weight, hypoglycemia

Rare (0.01% to 0.1%): Ketoacidosis

Frequency not reported: Increases in low-density lipoprotein cholesterol (LDL-C), increased serum phosphate


Renal related adverse reactions included acute kidney injury, renal impairment, acute prerenal failure. The incidence of renal related adverse reactions was 0.6%, 2.5%, and 1.3% in patients receiving placebo, 5 mg, and 15 mg, respectively.

Common (1% to 10%): Renal related adverse reactions

Frequency not reported: Increased serum creatinine, decreased eGFR
