Uses and warnings
BOXED WARNING: BOXED WARNING: LASIX is a potent diuretic that "if given in excessive amounts, can lead to a profound diuresis with water and electrolyte depletion." Careful medical supervision and individualized dosing are required. Key Warnings: - Risk of severe dehydration and electrolyte imbalances (hypokalemia, hyponatremia) - Ototoxicity (hearing loss/tinnitus), especially with rapid IV injection or renal impairment - In liver cirrhosis: sudden fluid/electrolyte shifts may precipitate hepatic coma - Hyperglycemia and diabetes precipitation possible - Acute urinary retention risk in patients with urinary obstruction ---
Edema: LASIX treats edema associated with congestive heart failure, liver cirrhosis, and renal disease, particularly when "an agent with greater diuretic potential is desired." Hypertension: Oral LASIX may be used alone or combined with other antihypertensive agents for treating high blood pressure in adults. The label notes that patients inadequately controlled with thiazides will likely not respond adequately to LASIX monotherapy. ---
