This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Focused allergic rhinitis practice parameter for Canada. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Confirm an allergic symptom pattern and relevant triggers while considering infection, medication, structural disease and asthma.
  • Use allergen avoidance where feasible, intranasal corticosteroid or other therapy matched to severity and preference, with technique reviewed.
  • Arrange allergy assessment when diagnosis is uncertain, symptoms remain uncontrolled or immunotherapy is being considered.
  • Persistent nasal obstruction, recurrent unilateral bleeding or loss of smell warrants assessment beyond allergy treatment.

Practical assessment and management workflow

1
Identify seasonal or perennial triggers, eye symptoms, asthma, sleep and occupational exposure.
2
Examine nasal mucosa and consider testing only when it will change avoidance or immunotherapy.
3
Teach correct intranasal corticosteroid technique and combine non-sedating treatment according to severity.
4
Review adherence and response and refer uncertain, refractory or immunotherapy-eligible disease.

Safety, red flags and urgent escalation

  • Escalate acute breathing compromise or systemic anaphylaxis rather than treating as rhinitis.
  • Avoid chronic topical decongestants because rebound congestion can develop.
  • Consider asthma control whenever allergic rhinitis and lower-airway symptoms coexist.
