Acute Rhinosinusitis
Antimicrobial prescribing: NHS Forth Valley
Acute Rhinosinusitis
Commonly viral infection and therefore antibiotics often not indicated
Symptoms <10 days: do not offer antibiotics as most resolve in 14 days without, and antibiotics only offer marginal benefit after 7 days
Symptoms >10 days: no antibiotic, or back-up antibiotic only if several of: purulent nasal discharge; severe localised unilateral pain; fever; marked deterioration after initial milder phase.
Systemically very unwell, or more serious signs and symptoms: immediate antibiotic.
Suspected complications: eg sepsis, intraorbital or intracranial, refer to secondary care.
Always offer self-care advice: paracetamol/ibuprofen for pain/fever. Nasal decongestants or saline have limited evidence of benefit but may help some. Consider high-dose nasal corticosteroid (if over 12 years) and symptoms >10 days.
