This medication is used to treat very low blood sugar levels (hypoglycemia). Certain conditions (such as tumor on the pancreas, cancer, leucine sensitivity) can cause the release of too much insulin. Insulin is a natural substance that lowers blood sugar. This drug works by preventing insulin release from the pancreas, helping to return the blood sugar to normal levels. Diazoxide is a thiazide drug, but has no diuretic ("water pill") effects like other thiazides.
Take this medication by mouth, as directed by your doctor, usually 2 to 3 times daily (every 8 to 12 hours). Your doctor may direct you to follow a special diet for your condition. Consult your doctor, pharmacist, or dietician for more details.
