Lasix(furosemide) is a potassium sparring diuretic which is a prescription medication. Diuretics work on the renal system and cause the kidneys to excrete more urine, they increase urine output. Lasix also causes the loss of potassium(an important electrolyte). When someone takes Lasix they should also be taking a potassium supplement to replace the potassium lost in the urine.

Lasix is indicated in many disease processes. Commonly, your physician will prescribe Lasix for patients with congestive heart failure(CHF). In CHF the heart is overburdened and the pumping action is diminished. Lasix pulls fluid out of the body decreasing the work load on the heart.

Lasix is generally well tolerated and has been in use for decades.

Lasix (loop diuretic) is a water pill that treats fluid retention by preventing the body from absorbing too much salt. The salt is passed with urine instead. It is used in people who have been diagnosed with congestive heart failure, liver disease, and specific kidney disorders, such as nephrotic syndrome. It is occasionally used for other purposes as well. It is very important not to become dehydrated while taking Lasix and it is also very important to take the medication exactly as prescribed by the physician. Because Lasix is a water pill, it will cause frequent urination.
