Common Side Effects Of Furosemide

Furosemide, commonly known by its brand name Lasix, is a potent diuretic often prescribed to treat fluid retention and swelling caused by various medical conditions, including heart failure, liver disease, and kidney disorders. While effective, furosemide is not without its side effects.
