• HF
• Gout
• Renal impairment
• OB: Lactation: Safety not established.
• Pedi: Newborns and infants with meconium aspiration syndrome, respiratory distress syndrome, transient tachypnea, pneumonia, sepsis, congenital diaphragmatic hernia, or congenital heart disease (may ↑ risk of pulmonary hypertension)
• Pedi: Newborns with hyperbilirubinemia (may ↑ risk of kernicterus)

CV: edema, hypotension, tachycardia, HF, palpitations.

Derm: hirsutism, rash.

Endo: hyperglycemia, DIABETIC KETOACIDOSIS, HYPEROSMOLAR NONKETOTIC COMA, hyperuricemia.

GI: abdominal pain, diarrhea, ILEUS, loss of taste, nausea, vomiting.

GU: glycosuria.

Hemat: neutropenia, thrombocytopenia.

MS: weakness.

Neuro: headache.

Resp: PULMONARY HYPERTENSION.

Drug-Drug:

• Concurrent diuretic therapy may potentiate hyperglycemic, hyperuricemic, and hypotensive effects.
• May enhance BP lowering response of any antihypertensive.
• May ↑ metabolism and ↓ effectiveness of phenytoin.
• Corticosteroids may ↑ hyperglycemia.
• May ↑ effects of warfarin.
• May alter the effects of insulins or oral hypoglycemic agents.

Drug-Natural Products:

• Glucosamine may worsen hyperglycemia.

(Generic available)

• Capsules: 100 mg;
• Oral suspension (chocolate-mint flavor): 50 mg/mL (contains 7.25% alcohol);

Hyperinsulinemic Hypoglycemia

• PO (Adults and Children): 1 mg/kg q 8 hr initially, further adjustments made on the basis of response. Usual maintenance dose is 3–8 mg/kg/day given in 2–3 divided doses every 8–12 hr.
• PO (Infants and Newborns): 2.7 mg/kg q 8 hr initially, further adjustments made on the basis of response. Usual maintenance dose is 8–15 mg/kg/day in 2–3 divided doses every 8–12 hr.

Proglycem

• Inhibits insulin release from the pancreas and decreases peripheral utilization of glucose.

• Increased blood glucose.

Therapeutic Classification: hyperglycemic

Pharmacologic Classification: pancreatics

Absorption: Well absorbed following oral administration.

Distribution: Crosses the blood-brain barrier and placenta.

Protein Binding: >90%.

Metabolism/Excretion: 50% metabolized by the liver; 50% excreted unchanged by the kidneys.

Half-life: 10–36 hr (↑ in renal impairment).

(Blood glucose concentrations)

• Instruct patient to take medication as directed, at the same time each day. Do not skip or take extra doses.
  • Encourage patient to follow prescribed diet, medication, and exercise regimen to prevent hypoglycemic or hyperglycemic episodes.
  • Caution patient that sharing diazoxide with others may be dangerous.
  • Review signs of hypoglycemia and hyperglycemia with patient.
  • Advise patient not to switch from capsule to oral suspension form without consulting health care professional, because oral suspension produces higher blood concentrations.
  • Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications.
  • Advise patient to inform health care professional of medication regimen prior to treatment or surgery.
  • Instruct female patients to inform health care professional if pregnancy is planned or suspected or if breastfeeding.
  • Emphasize the importance of routine follow-up exams, especially during the first few wk of therapy.
