A 45-year-old male patient was treated with canagliflozin 100 mg once daily orally for type 2 diabetes mellitus due to poor blood sugar control. On the 4th day of medication, the patient developed slight abdominal distension and fatigue; on the 5th day, the patient felt nausea and general fatigue, and the color of urine became dark brown. The laboratory tests showed serum creatinine (Scr) 136 μmol/L, blood urea nitrogen (BUN) 9.7 mmol/L, urine protein (+), and urinary occult blood (++). Acute kidney injury induced by canagliflozin was considered. Canagliflozin was stopped, and acarbose 50 mg (before meal), 2 Haikun Shenxi capsules (海昆肾喜胶囊), and 3 Jinshuibao capsules (金水宝胶囊) orally thrice daily were given.
