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

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