Prescribing Notes:

  • The vast majority of respiratory tract illness is self-limiting. Do not prescribe an antibiotic for uncomplicated coughs and colds when the infection is likely to be viral in nature – only use antibiotics when there is evidence of bacterial infection. Purulent sputum alone is not a marker for antibiotic treatment.
  • Antibiotics are of limited benefit in acute cough and bronchitis if there are no other significant co-morbidities. Symptom resolution can take 3 weeks.
  • Dual antibiotic therapy is not appropriate for treatment in this pathway.
  • Consider pertussis if prolonged acute cough lasting for 14 days or more without apparent cause, additional clinical features and contact with confirmed case in previous 21 days. See formulary recommendations for pertussis.
