Allergic Rhinitis

Allergic rhinitis is diagnosed from compatible symptoms and exposure history. A positive skin-prick or specific IgE test shows sensitisation, which is clinically relevant only when it matches the history.

Treatment is stepped to symptom burden: antihistamine for intermittent itch and sneeze-predominant symptoms, regular intranasal corticosteroid for troublesome obstruction or moderate-to-severe disease, and a fixed intranasal antihistamine/corticosteroid combination when monotherapy is insufficient. ^{BSACI rhinitis 2017 ARIA-EAACI2024–2025}

Before escalating, assess coexisting asthma, spray technique and adherence. Allergen immunotherapy requires clinically relevant sensitisation, controlled asthma and product-specific eligibility and safety assessment. ^{Acarizax UK SmPC}
