This protocol covers children aged 3–14 presenting with sore throat where β-hemolytic streptococcal infection (group A, C, or G) is highly suspected or confirmed, a McIsaac score of at least 3, and no penicillin allergy — specifically when a first-line penicillin course has not achieved the expected clinical response.
Antibiotic treatment is warranted when β-hemolytic streptococcal infection (group A, C, or G) is highly suspected or confirmed. In children aged 3–14 years with a McIsaac score of at least 3 and no penicillin allergy, a structured antibiotic approach is indicated.
When first-line therapy does not bring the patient to symptom resolution within the expected window, the criteria for escalating to this protocol are met.
The first-line regimen for this age group was Penicillin V (or Phenoxymethylpenicillin–Benzathin). The threshold for advancing to this protocol is clear: the patient has not become free of symptoms within 48 hours on that regimen. Once that goal is unmet, this next-line protocol applies.
For cases meeting the above criteria — confirmed or suspected streptococcal tonsillitis in a child aged 3–14, McIsaac score ≥ 3, and documented failure of penicillin — an oral cephalosporin is the class of antibiotic this protocol directs. The specific agent, dosing schedule, and full regimen details are in the complete protocol below.

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:
Only very selected indications support administration of oral cephalosporins (for example: cefadroxil, cefalexin) including the failure of penicillin V, frequent recurrences, and whenever a more reliable eradication of b-hemolytic streptococci is desirable.
