Hypersensitivity: May occur in patients with or without history of allergy or bronchial asthma; cross-sensitivity with sulfonamides also may occur. Renal function impairment: May precipitate azotemia; use with caution. Lipids: May cause increased concentrations of total serum cholesterol, total triglycerides and LDL in some patients. Postsympathectomy patients: Antihypertensive effects may be enhanced.

Drug Mode of Action ::  

 Action Inhibits reabsorption of sodium and chloride in proximal portion of distal convoluted tubules.

Drug Interactions ::


Allopurinol: Concurrent use may increase incidence of hypersensitivity reactions to allopurinol. Amphotericin B, corticosteroids: May intensify potassium depletion. Anticholinergics: May increase chlorthalidone absorption. Anticoagulants: May diminish anticoagulant effects. Bile acid sequestrants: May reduce chlorthalidone absorption. Give chlorthalidone ³ 2 hr before bile acid sequestrant. Calcium salts: Hypercalcemia may develop. Diazoxide: May cause hyperglycemia. Digitalis glycosides: Diuretic-induced hypokalemia and hypomagnesemia may precipitate digitalis-induced arrhythmias. Lithium: May decrease renal excretion of lithium. Loop diuretics: Synergistic effects may result in profound diuresis and serious electrolyte abnormalities. Methenamines, nonsteroidal anti-inflammatory drugs: May decrease effectiveness of chlorthalidone. Sulfonylureas, insulin: May decrease hypoglycemic effect of sulfonylureas.

Drug Assesment ::


  • Obtain patient history, including drug history and any known allergies.
  • Assess serum electrolytes and digitalis level (if appropriate) periodically.
  • Closely monitor blood sugar, complete blood count and platelets.
  • Review triglyceride and cholesterol levels periodically.
  Orthostatic hypotension, dizziness, drowsiness, syncope, potassium depletion, nausea, vomiting, lethargy, coma, GI irritation, GI hypermobility, seizures

Drug Storage/Management ::


  • Administer drug early in AM so that diuresis will occur during day rather than night.

  • Teach patient signs and symptoms of hypokalemia (weakness, cramps, nausea, and dizziness), especially if patient is taking digitalis.
  • Explain diuretic effects of drug so patient is aware of expected and potential outcomes.
  • Instruct patient to follow low-sodium diet to enhance action of medication.
  • If high-potassium diet is recommended by physician, help patient identify appropriate meal plans or potassium supplements.
  • Teach patient to record weight daily at a consistent time and to notify physician if weight fluctuates ± 5 pounds.
  • Tell patient to notify physician of salt or water retention occurs (eg, swelling of feet, ankles, calves).
  • Caution patient to avoid exposure to sunlight and to use sunscreen or wear protective clothing to avoid photosensitivity reaction.
  • Advise patient to avoid sudden position changes to prevent orthostatic hypotension. Have patient get up slowly and dangle feet before getting out of bed.
  • Caution patient not to take any otc medications without consulting physician.
