LASIX (Furosemide Tablets) contain furosemide, a potent diuretic that helps the body eliminate excess fluid by increasing urine production. This medication is indicated for the treatment of edema associated with congestive heart failure, liver disease, or kidney disorders, as well as hypertension. Furosemide works by inhibiting the reabsorption of sodium and chloride ions in the kidneys, leading to increased urine output and reduced fluid retention.
