Other antibiotics proven effective for GABHS pharyngitis are the penicillin congeners, many cephalosporins, macrolides, and clindamycin. Clindamycin may be of particular value because its tissue penetration is considered equivalent for both oral and IV administration. Clindamycin is effective even for organisms that are not rapidly dividing (Eagle effect), which explains its great efficacy for GABHS infection. Vancomycin and rifampin have also been useful. Reduced-frequency dosing is recommended to improve compliance with medication regimens. A consensus on the efficacy of such dosing has not yet been formulated.
