Seasonal allergic rhinitis is an immunoglobulin E (IgE)–mediated inflammatory disorder of the nasal mucosa triggered by cyclical, outdoor aeroallergens such as tree, grass, or weed pollens and seasonal mold spores This immune response clinically manifests as paroxysmal sneezing, nasal pruritus, watery rhinorrhea, nasal congestion, and postnasal drip that predictably recur during specific times of the year

Exposure to airborne allergens prompts mast cell degranulation and subsequent release of inflammatory mediators, including histamine and leukotrienes, alongside late-phase eosinophilic recruitment
