If you are allergic to cephalosporin and levofloxacin capsules, you can consider taking clarithromycin, doxycycline and furantoin enteric tablets. If you have time, we suggest you go to the hospital for routine urine tests and ultrasound of the urinary tract, and if you have a gynecological condition, you can have an ultrasound of the uterine adnexa to clarify the cause.
