A 6-week-old infant presents with recurrent episodes of unresponsiveness and seizures. Repeated bedside glucose values during episodes are 22–35 mg/dL. He requires a glucose infusion rate (GIR) of 13 mg/kg/min to maintain glucose >50 mg/dL. Critical sample during hypoglycemia shows: insulin 9.8 uU/mL, C-peptide elevated, beta-hydroxybutyrate 0.3 mmol/L, free fatty acids low, cortisol 22 mcg/dL, GH 15 ng/mL. What is the MOST appropriate initial pharmacotherapy?
