I was taking doxycycline for an infection of streptococcus spp. causing epididymitis. I was healing under this antibiotic, then the doctor added ciprofloxacin to my treatment, so I am taking 100 mg of doxycycline and 500 mg of ciprofloxacin.
My question is, do the two antibiotics have antagonistic effects? If so, is it a one-way antagonism and which way?
