I have a history of recurring UTI's.Las year I was sen by a uro-gynecologist who put me on a 3 month prophylactic course of macrobid, 100mg daily. This helped and I was fine for over a year with no recurrences. A month ago I had another UTI, was put on 5 days of Cipro, 250 mg 2 times a day (I had a sinus infection at the same time). I could feel after 5 days that it wasn't gone, so I was given another 5 days, at 500mg 2 times a day. Thank G-d, I could tell it worked. For 2 weeks. Then....that pressure and funny urgency to go to the bathroom came back. I was put on Macrobid, 100mg 2 times a day for 5 days. I could tell it wasn't enough. that's where I'm at now. Went to a dr. tonite who did a dipstick test in my urine. he said there were mild leukocites, but given my past several weeks, he wants to send it out to be cultured before he prescribes anything else.He said if I feel worse, get fever, etc., call him right away and he'll start me on something until the culture comes back. I guess I'm afraid of some super bug bacteria that's resistant to Cipro and Macrobid....What is your advice?
