Furosemide

Furosemide (Lasix) is a potent loop diuretic "water pill" that treats fluid retention (edema) from heart, liver, or kidney issues and high blood pressure by making kidneys excrete salt and water, reducing fluid buildup and lowering blood pressure. Common side effects include frequent urination, dizziness, headache, and potential hearing issues, while severe ones need immediate care. It works by inhibiting salt reabsorption in the kidneys, increasing urine flow.
