Patient handout

Acute rhinosinusitis (viral vs ABRS; complications)

PRODUCTION

1. Your condition

This handout is for acute rhinosinusitis (viral vs abrs; complications). Your care team identified this based on: nasal obstruction/congestion + anterior or posterior purulent discharge + facial pain/pressure/fullness (cardinal ars symptom cluster; ≥2 of these = rhinosinusitis) (payne aao-hns 2025 pmid 40742114; epos 2020 pmid 32077450).

Other reasons your team may use this plan: uri-type symptoms persisting ≥10 days without improvement — the persistent-illness abrs pattern (chow idsa 2012 pmid 22438350; wald aap 2013 pmid 23796742); "double-sickening" — new fever / worsening discharge / worsening facial pain after an initially improving uri (chow idsa 2012 pmid 22438350; epos 2020 pmid 32226949); severe onset — high fever (≥39 °c / 102.2 °f) with purulent nasal discharge for ≥3-4 consecutive days at illness onset (chow idsa 2012 pmid 22438350; wald aap 2013 pmid 23796742).

2. Your medications

Take these medications exactly as prescribed. Do not stop or change a dose without talking to your provider.

MedicationStarting doseHowWhenWhat it does
watchful_waiting_no_antibiotic_with_7day_safety_netPayne AAO-HNS 2025 (PMID 40742114) — watchful waiting (symptomatic care + safety-net follow-up if not improving by 7 d or worsening) for ALL uncomplicated ABRS; Lemiengre Cochrane 2018 (PMID 30198548) — ~46% cured at 1 wk / ~64% at 14 d without antibiotics; antibiotic NNTB ~19 (clinical dx), NNH ~8
intranasal_corticosteroid_eg_fluticasone_or_mometasonePayne AAO-HNS 2025 / EPOS 2020 (PMID 32077450) — intranasal corticosteroid is an option for symptom relief in viral ARS and ABRS (modest benefit, faster symptom resolution); RxCUI deferred — multiple branded INS products, no single confident MIN
isotonic_saline_nasal_irrigationPayne AAO-HNS 2025 / EPOS 2020 — saline irrigation/spray is a low-harm symptomatic option for ARS
acetaminophen650-1000 mgPOq6h PRNPayne AAO-HNS 2025 — analgesics/antipyretics for pain and fever in viral ARS and ABRS (NSAID alternative if no contraindication)

Plan: Acute rhinosinusitis — watchful-waiting-first ladder (viral ARS → uncomplicated ABRS → penicillin-allergy → complicated/IV)

3. When to call your provider

Contact your care team if any of the following happen:

  • Orbital signs (proptosis/ophthalmoplegia/acuity loss) → ED + contrast CT + route to ophtho.orbital-cellulitis.core.v1 (Payne AAO-HNS 2025)
  • Intracranial signs (meningism/altered mentation/Pott's puffy) → ED + contrast CT + route to neuro.bacterial-meningitis.core.v1 (Chow IDSA 2012)
  • Systemic toxicity / qSOFA ≥2 → route to id.sepsis.core.v1 (SSC 2021)
  • Immunocompromised/DKA + facial pain/eschar → emergent ENT for invasive fungal rhinosinusitis (EPOS 2020)

4. When to seek emergency care

Call 911 or go to the nearest emergency room right away if you have:

  • Proptosis, painful or restricted eye movement, diplopia, reduced visual acuity/colour vision, RAPD, or marked periorbital oedema with systemic features — orbital cellulitis or subperiosteal/orbital abscess (Payne AAO-HNS 2025 PMID 40742114; Chow IDSA 2012 PMID 22438350)(life-threatening)
  • Severe/worsening frontal headache, meningism, photophobia, vomiting, seizure, altered mentation, or focal neurologic deficit with a sinus source — meningitis, epidural/subdural empyema, brain abscess, or venous sinus thrombosis (Chow IDSA 2012 PMID 22438350)(life-threatening)
  • Doughy, tender forehead/scalp swelling over the frontal bone with frontal sinusitis — Pott's puffy tumour (frontal bone osteomyelitis with subperiosteal abscess), high risk of concurrent intracranial extension (Chow IDSA 2012 PMID 22438350)(life-threatening)
  • Bilateral/progressive periorbital oedema, ophthalmoplegia (CN III/IV/VI), proptosis, ptosis, V1/V2 sensory loss, with severe headache and toxicity following sphenoid/ethmoid sinusitis — septic cavernous sinus thrombosis (Chow IDSA 2012 PMID 22438350)(life-threatening)
  • Immunocompromised (neutropenia, transplant, haematologic malignancy) or poorly controlled diabetes/DKA with facial pain, nasal eschar, anaesthetic or necrotic mucosa, rapidly progressive orbital/CNS findings — acute invasive fungal rhinosinusitis (mucormycosis / Aspergillus) (EPOS 2020 PMID 32077450; Chow IDSA 2012 PMID 22438350)(life-threatening)
  • qSOFA ≥2, hypotension on adequate fluids, or NEWS2 high-score systemic toxicity with a complicated-sinusitis source (SSC 2021; RCP NEWS2 2017)

5. Follow-up

Educate on natural history (viral ARS self-limited; antibiotic NNT ~11-15, NNH ~8 for adverse effects — Lemiengre Cochrane 2018; Young Lancet 2008) and antibiotic stewardship. Define recurrence (≥4 ABRS episodes/yr with symptom-free intervals) and the CRS boundary (symptoms ≥12 wk with objective sinonasal inflammation → CRS pathway / ENT referral). Return precautions: orbital swelling, visual change, severe/worsening headache, neck stiffness, altered mentation → emergency re-presentation. ENT referral for recurrent ARS, complications, anatomic factors, immunodeficiency, or chronic transition.
