I have taken Cipro for Urniary Tract Infections on and off for about 7 years. Last year the frequency of infections was about every 2 months. This winter I have had less than a month between symptoms. My doctor gave me a prescription for Macrobid in case I need it. I have taken it for the first time the past three days and the infection is still quite apparent especially during the night when I can feel the internal discomfort. Normally with the use of Cipro I would be on the mend by the end of 3 days. Is there any merit in taking both meds or should I or even can I just switch back to Cipro mid treatment.
