Our review of Neisseria gonorrhoeae pharyngeal treatment failures from sexually transmitted infection clinics in Alberta suggests that treatment failures with oral cefixime monotherapy were not related to elevated cefixime minimum inhibitory concentrations. Dual therapy with oral cefixime and azithromycin may be a suitable alternate for the treatment of pharyngeal gonorrhea.
