Warnings
Contraindications
Hypersensitivity to diazoxide, thiazides, or sulfonamide derivatives
Cautions
Use caution in coronary or cerebral insufficiency, DM, extravasation, heart failure (may increase fluid retention), cardiovascular insufficiency, gout, hypotension, hypokalemia, liver disease, renal dysfunction
Pregnancy
Compensatory HTN (aortic coarctation, arteriovenous shunt)
Ineffective in pheochromocytoma
Nonketotic hyperosmolar coma may occur during treatment; transient cataracts reported
May displace bilirubin from albumin; use caution in newborns with hyperbilirubinemia
The antidiuretic property of diazoxide may lead to significant fluid retention, which in patients with compromised cardiac reserve, may precipitate congestive heart failure; the fluid retention will respond to conventional therapy with diuretics
Concomitantly administered thiazides may potentiate the hyperglycemic and hyperuricemic actions of diazoxide
Ketoacidosis and nonketotic hyperosmolar coma reported in patients treated with recommended doses usually during intercurrent illness; prompt recognition and treatment essential and prolonged surveillance following the acute episode necessary because of long drug half-life of approximately 30 hours; occurrence of these serious events may be reduced by careful education of patients regarding monitoring urine for sugar and ketones and for prompt reporting of abnormal findings and unusual symptoms to healthcare provider
Effects of diazoxide on the hematopoietic system and the level of serum uric acid kept in mind; the latter should be considered particularly in patients with hyperuricemia or a history of gout
Antihypertensive effect of other drugs may be enhanced by diazoxide; should keep this in mind when administering it concomitantly with antihypertensive agents
Because of protein binding, administration of diazoxide with coumarin or its derivatives may require reduction in dosage of anticoagulants
Pulmonary hypertension in newborns and infants
- July 16, 2015: FDA warns clinicians to watch for signs of pulmonary hypertension in infants treated for hypoglycemia with diazoxide and discontinue the drug if symptoms appear
- There have been 11 cases identified since the drug was approved (1973) and once diazoxide was discontinued, the symptoms resolved
- Signs of respiratory distress include flaring nostrils, grunting, unusual chest movements, rapid breathing, difficulty feeding, or a bluish tint to the lips or skin
- Monitoring is especially important for infants who have other risk factors for pulmonary hypertension (eg, meconium aspiration syndrome, respiratory distress syndrome, transient tachypnea of the newborn, pneumonia, sepsis, congenital diaphragmatic hernia, and congenital heart disease)

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

DIAZOXIDE - ORAL
(dye-uh-ZOX-ide)
COMMON BRAND NAME(S): Proglycem
USES: 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).
HOW TO USE: 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 frequently when you first start taking the drug to find the best dose for you. Follow your doctor's directions carefully.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.Tell your doctor if your condition lasts or gets worse after 2 to 3 weeks.
SIDE EFFECTS: Nausea, loss of appetite, stomach upset, and changes in sense of taste may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Abnormal growth of body hair, especially on the forehead/back/arms/legs, may occur. This is usually not permanent and will go away when the drug is stopped.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.This medication can cause sodium and water retention which can cause serious heart problems. Tell your doctor right away if any of these serious side effects occur: swelling of arms/legs/hands/feet, unexplained weight gain, shortness of breath, unusual tiredness.This medication may cause your blood sugar to become too high. Checking your blood sugar and urine for sugar/ketones regularly and telling your doctor the results will help prevent this side effect. High blood sugar can be very serious and worsen quickly. Tell your doctor right away if any of these signs of very high blood sugar occur: need to urinate more often, unusual thirst, fruity breath odor, dizziness, unusual weight loss, deep/rapid breathing, bluish color of lips/skin, extreme drowsiness/confusion, weakness.Tell your doctor right away if any of these unlikely but serious side effects occur: easy bruising/bleeding, fainting, fast/pounding heartbeat, face/muscle twitching, toe/joint pain, unusual restlessness, muscle cramps/stiffness, shaking (tremor).A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects.
