Hi Dizziness is not likely to be due to the infection unless OT is so severe that it had reduced your BP but that is now unlikely considering that you feel the fever had come down. Ciprofloxacin is an excellent drug but has been known to cause profound weakness and might be the cause of your present condition. You can take a multivitamin preparation for whatever it is worth as well. I suggest you take plenty of fluids and eat well for the next couple of days till you complete your antibiotics course but if you are not comfortable, please stop the antibiotic and get yourself examined by a doctor.
