Increases sodium and water excretion by inhibiting sodium reabsorption in distal tubules; promotes excretion of chloride, potassium, magnesium, and bicarbonate. Also may produce arteriolar dilation, reducing blood pressure.
Capsules: 12.5 mg
Oral solution: 10 mg/ml, 100 mg/ml
Tablets: 12.5 mg, 25 mg, 50 mg, 100 mg
⊘Indications and dosages
➣ Edema caused by heart failure, renal dysfunction, cirrhosis, corticosteroid therapy, or estrogen therapy
Adults: 25 to 100 mg P.O. daily as a single dose or in divided doses. Maximum dosage is 200 mg/day.
➣ Mild to moderate hypertension
Adults: Initially, 12.5 mg daily P.O.; then, based on blood pressure response, may give 12.5 to 50 mg/day P.O. Higher dosages may be given in refractory cases.
Children ages 2 to 12: 1 to 2 mg/kg/day P.O. in single dose or two divided doses, not to exceed 100 mg/day
Children younger than age 2: 1 to 2 mg/kg P.O. as single dose or divided doses, not to exceed 37.5 mg/day; infants less than age 6 months may require dosage of 3 mg/kg/day in two divided doses.
• Ménière's disease
• Hypersensitivity to drug, other thiazides, sulfonamides, or tartrazine
• Renal decompensation or anuria
Use cautiously in:
• renal or severe hepatic impairment, fluid or electrolyte imbalances, gout, systemic lupus erythematosus, hyperparathyroidism, glucose tolerance abnormalities, bipolar disorder
• elderly patients
• pregnant or breastfeeding patients.
• Give with food or milk if GI upset occurs.
• Administer early in day so diuretic effect doesn't disturb sleep.

Drug-drug.Adrenocorticotropic hormone, corticosteroids: increased risk of intensified electrolyte depletion, particularly hypokalemia
Allopurinol: increased risk of hypersensitivity reaction
Amphotericin B, corticosteroids, digoxin, mezlocillin, piperacillin, ticarcillin: increased risk of hypokalemia
Antihypertensives, barbiturates, nitrates, opioids: increased hypotension

• Monitor blood pressure, fluid intake and output, and daily weight.
• Assess electrolyte levels, especially potassium. Monitor for signs and symptoms of hypokalemia.
• Monitor blood urea nitrogen and creatinine levels.
• Check blood glucose level in diabetic patients.
• Assess for signs and symptoms of gout attacks in patients with gouty arthritis.
• Advise patient to take with food or milk if GI upset occurs.
• Tell patient to take early in day to avoid nighttime urination.
• Instruct patient to track intermittent doses on calendar.
• Tell patient to weigh himself daily, at same time on same scale and wearing same clothes.
☞ Instruct patient to report decreased urination, swelling, unusual bleeding or bruising, dizziness, fatigue, numbness, and muscle weakness or cramping.
• Instruct patient to move slowly when sitting up or standing, to avoid dizziness from sudden blood pressure decrease.
• Caution patient to avoid driving and other hazardous activities until he knows how drug affects concentration and alertness.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, herbs, and behaviors mentioned above.
