Proglycem (oral diazoxide) is a non-diuretic benzothiadiazine derivative that works by preventing insulin release from the pancreas, helping to return the blood sugar to normal levels used to treat low blood sugar (hypoglycemia) related to certain cancers that affect the pancreas and cause it to release too much insulin. Common side effects of Proglycem include nausea, vomiting, loss of appetite, stomach pain or upset, diarrhea, changes in sense of taste, temporary increase in growth of body hair (especially in women and children), headache, dizziness, anxiety, weakness, or itching or skin rash.
The usual daily dosage of Proglycem for adults and children is 3 to 8 mg/kg, divided into two or three equal doses every 8 or 12 hours. The usual daily dosage for infants and newborns is 8 to 15 mg/kg divided into two or three equal doses every 8 to 12 hours. Proglycem may interact with diuretics (water pills), chlorpromazine, phenytoin, blood thinners, or drugs to treat high blood pressure or a prostate disorder. Tell your doctor all medications and supplements you use. During pregnancy, Proglycem should be used only when prescribed. If you become pregnant, or think you may be pregnant, tell your doctor. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

Frequent and Serious
Sodium and fluid retention is most common in young infants and in adults and may precipitate congestive heart failure in patients with compromised cardiac reserve. It usually responds to diuretic therapy (See DRUG INTERACTIONS).
Infrequent but Serious
Diabetic ketoacidosis and hyperosmolar nonketotic coma may develop very rapidly. Conventional therapy with insulin and restoration of fluid and electrolyte balance is usually effective if instituted promptly. Prolonged surveillance is essential in view of the long half-life of PROGLYCEM® (See OVERDOSAGE).
