Lasix/Furosemide

My doctor prescribed furosemide for some pretty bad bilateral pitting ankle edema of as yet unknown cause.

I am 5'4" and 116lbs.  She said this is a very strong medication and she prescribed me 15 of the 20mg tablets, told me to cut them in half and take one half a tablet every other day. (So 10mg every other day, and then I will see her again in a month.)

I took the first dose today and had an increase in frequency of urination, but my ankles look as bad if not worse than ever.  I weighed myself first thing this morning before taking the medication, and now at the end of the day I weigh nearly 5 full pounds more.  

Do you have any information on how long it would normally take for furosemide to show a reduction in edema?  I know it's only been one day, but my ankles are so disturbingly large, and my dose is so small I worry I'm not taking enough to do me any good.  Is this medication normally dosed according to body weight?  

Thanks for your help!

Diuresis generally begins 30 to 60 minutes after oral administration. It is not necessarily dosed according to body weight, but rather disease state and patient's response.  If you are still not seeing any difference, I would contact your doctor.
