This medication is used to treat very low blood sugar (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.

Diazoxide should not be used to treat low blood sugar from poor nutrition/diet (functional hypoglycemia).

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.

Do not switch between the capsule and suspension form of this medication without talking with your doctor first. Your dose may need to be adjusted. If you are using the suspension, shake the bottle thoroughly before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Do not use the suspension if it has turned a dark color. Discard it. (See Storage section.)

The dosage is based on your weight, medical condition, and response to treatment. You will need to check your blood sugar and check your urine for sugar and ketones regularly as directed and share the results with your doctor. Your doctor will adjust the dose based on these tests. Your doctor may change your dose often when you first start taking the drug to find the best dose for you. Follow your doctor's directions carefully.
