Infants and Children: Leucine sensitivity, islet cell hyperplasia, nesidioblastosis, extrapancreatic malignancy, islet cell adenoma, or adenomatosis. Diazoxide Oral Suspension may be used preoperatively as a temporary measure, and postoperatively, if hypoglycemia persists.

When other specific medical therapy or surgical management either has been unsuccessful or is not feasible, treatment with diazoxide should be considered.
