A 13-year-old patient presenting with a fever of 38.7°C, sudden onset of sore throat, and dysphagia, is brought in for medical management. A series of tests reveals streptococcal pharyngitis. The physician orders penicillin G benzathine. If the patient is allergic to this kind of antibiotic, the second line of antibiotics is:

Cephalosporins
Erythromycin
Penicillin V
Amantadine

Explanation

Answer: C - Erythromycin is the second line of antibiotic given to this patient. Erythromycin is classified as a macrolide. Cephalosporins are pharmacologically related to penicillins; therefore, this group of drugs is not appropriate for this patient. Amantadine is effective against pharyngitis caused by influenza A virus.
