Hello, My mother aged 56 yrs is was detected with chronic pyelonephritis in 2006 and we also came to know that she had a right side- small hypoplastic kidney. The Renal scan reveals: The split function of the right kidney is 22.5%and left is 77.5% while the GFR (ml/min) in right kidney is 9.693 and left is 33.4 , that is the total GFR is 43.1 which is much low than the normal range of 75- 120ml/mt. She is having painful and frequent urination and had fever last week which settled with cotrimoxazole (Septran) tablets and then the urologist prescribed levofloxacin 250mg once a day and she was fine but again yesterday night she had frequent and painful urination so i told her to take one more levofloxacin as we coudnt talk to the doctor at night. I wanted to know she can start taking CITRALKA SYRUP? Will it have side effects and whether she can take it or not.. Kindly Reply soon.
