Lasix (furosemide) is stronger: To remove water effectively, you need lasix, (furosemide) not spironolactone. However, spironolactone has special uses in liver disease and in some heart cases. For kidney disease, Lasix (furosemide) is more effective. Spironolactone should be used with caution in these cases due to risk of high potassium that could have serious effects.

Diuretics: Both are diuretics, but they work in very different ways. Lasix (furosemide) will cause the body to excrete potassium while spironolactone will cause the body to retain potassium. This is an important difference. These diuretics are sometimes given together, but they are not interchangeable.
