Antibiotic therapy is indicated only in case of a highly suspected or proven b-hemolytic streptococci infection (of group A, C, or G).

For patients with sore throat in times and regions without epidemic occurrence of b-hemolytic streptococcal infection, a low regional incidence of streptococcal sequelae and a McIsaac-Score of at least 3, oral medication is recommended as follows

Age 3–14 years:

Penicillin V (100,000 IU/kg/day in three doses for 7 days), or Phenoxymethylpenicillin–Benzathin (50,000 IU/kg/day in two doses for 7 days)

With adequate therapy, most of the patients, especially adolescents and adults, are free of symptoms within 48 h.
