Pharyngitis / Sore Throat / Tonsillitis

Comments from Expert Advisory Committee

  • The majority of sore throats are viral; most patients do not benefit from antibiotics. Consider a delayed antibiotic strategy and explain soreness will take about 7 days to resolve.
  • Antibiotics make little difference to how long symptoms last or the number of people whose symptoms improve.
  • Withholding antibiotics is unlikely to lead to complications 
  • Offer all patients advice about self-care and to seek medical help if symptoms worsen significantly.
  • Reassess if symptoms worsen rapidly or significantly, taking account of: alternative diagnoses such as scarlet fever or glandular fever or any symptoms or signs suggesting a more serious illness or condition.
  • Consider referral to hospital if they have acute sore throat associated with severe systemic infection or severe suppurative complications (such as abscess).
  • If scarlet fever is suspected it is advisable to treat for 10 days duration.
  • HPSC update on group A Streptococcus
