Furosemide is powerful diuretic available in tablet and injection form. Furosemide (trade name – Lasix), is used to treat edema, a retention of fluid that accompanies disorders such as heart failure, kidney disease, and cirrhosis of the liver.
Furosemide may also be prescribed in the treatment of high blood pressure and sometimes is used in the treatment of overdoses of certain drugs, such as barbiturates, because it increases the flow of urine.

Furosemide Side Effects

Furosemide may cause nausea and diarrhea, and it may, in rare cases, result in deafness.
The use of furosemide may also cause a de crease in the levels of sodium, calcium, and potassium in the blood. For this reason, potassium supplements should be prescribed when furosemide is taken for a long period of time.
