i was just given 500mg of Cipro 2 x a day. This seems heavy dose (for a returned infection of bladder/kidneys that never really went away on Zithromax-just went nto hiding I guess. Is it OK to cut the pill in half and do 250mg as I am medictaion sensitive and although I don't mind the 1,000mg first day it seems a lot. Any advice? I see urologist Wednesday 8th for cysto and kidney scan. Regards Anne C Feel free to but in anyone with advice.
