Diazoxide, sold under the brand name Proglycem among others, is a medication used to treat low blood sugar due to a number of specific causes.[4] This includes islet cell tumors that cannot be removed and leucine sensitivity.[4] It can also be used in refractory cases of sulfonylurea toxicity.[5] It is taken by mouth.[4]

Diazoxide, used as the salt diazoxide choline, and sold under the brand name Vykat XR, is used for the treatment of hyperphagia in people with Prader-Willi syndrome.[3] It was approved for this use in the United States in March 2025.[6]

Common side effects include high blood sugar, fluid retention, low blood platelets, a fast heart rate, increased hair growth, and nausea.[4] Other severe side effects include pulmonary hypertension and heart failure.[4] It is chemically similar to thiazide diuretics.[4] It works by decreasing insulin release from the pancreas and increasing glucose release by the liver.[4]

Diazoxide was approved for medical use in the United States in 1973.[4] It is on the World Health Organization's List of Essential Medicines.[7] It is available as a generic medication.[8]
