I have been on furisomide 40mg for 30 days with no results. have gained 17# of fluid. i am drinking 40oz. water a day. any suggestions as to why i am still retaining fluid?

Though you take 40 ox of water, you may be consuming liquid in other forms:, coffee, tea, juice, soup, alcohol. In absence of any fluid retaining diseases, like CHF, cirrhosis, nephrotic syndrome, pregnancy, you are retaining fluid. Please ask your doctor about your kidney function and if cutting back on salt intake would help. Adding another class of diuretic may work in some cases. Hope it helps
