Edema
"I&#039;ve been taking Lasix for about 10 years for swelling in my feet/ankles. I only have one kidney and have hypertrophic cardiomyopathy.  I take 80 mg in the morning.  It does not always take all the swelling out, but if I miss just one dose, I can tell it by the afternoon.  Of course, if I take it in the afternoon, I&#039;m up all night.  NOTE: There IS a difference in taking the Lasix as opposed to the generic furosemide.  For me, the generic is absolutely useless.  My mother had the same problem, so maybe it&#039;s genetic.  I&#039;ve taken as much as 200 mg of generic at one time with no effect whatsoever.  I&#039;ve noticed no side effects from the Lasix."
