Edema
"My cardiologist put me on Lasix over a month ago due to edema of the legs and ankles. My rate of urination was about every 45 minutes nowhere as bad as some of the reviewers. I refilled my prescription and noticed an immediate change. Instead of every 45 minutes, it changed to every hour and a half. The only difference is the manufacturer.  The Lasix made by Sandoz seems to work fine. "
