  • Summary of Lasix vs. Aldactone

    Summary for Diuretic (water pill)
    Prescription only

    Furosemide (Lasix) is a loop diuretic, a type of water pill. Furosemide (Lasix) is used to relieve swelling from extra fluids in children and adults. This medication can also lower blood pressure, though it's not a first-choice option for this condition. Furosemide (Lasix) comes as a tablet that's taken by mouth, typically once or twice daily. It's also available as an oral solution for people who've trouble swallowing tablets. Furosemide (Lasix) will cause you to urinate more often as a side effect, so it's best to not take this medication too close to bedtime.

    Summary for Potassium sparing diuretic
    Prescription only

    Spironolactone (Aldactone) is a type of potassium-sparing diuretic (water pill). It's used to treat heart failure, high blood pressure, and swelling from kidney or liver problems in adults. Because it blocks aldosterone (a hormone that affects sodium and potassium levels), spironolactone (Aldactone) can also treat conditions where there's too much aldosterone. Spironolactone (Aldactone) is taken by mouth, generally once or a few times a day, depending on your condition. Some common side effects of this medication include breast tenderness (males and females) and loss of libido (in males).
