In mild intermittent allergic rhinitis, symptoms occur infrequently and do not impair quality of life. When standard first-line management fails to achieve adequate relief, a structured next-step approach is indicated for residual nasal congestion, rhinorrhea, and nasal ocular symptoms.
Mild intermittent allergic rhinitis is characterised by symptoms occurring fewer than four days per week or fewer than four weeks per year, without interference with daily life or quality of life. This protocol applies when that presentation has not responded adequately to first-line therapy.
The previous treatment step consisted of allergen avoidance and patient education, combined with a second-generation nonsedating oral or intranasal antihistamine used as needed. The intended goal was relief of histamine-mediated symptoms — sneezing, nasal pruritus, and rhinorrhea. Failure to reach those goals is the trigger for escalation to this protocol.
The full protocol outlines targeted add-on options for symptom-specific residual complaints, with important guidance on the appropriate duration of certain interventions to avoid a recognised complication of overuse.
Clinical goals: resolution of nasal congestion, rhinorrhea, and nasal ocular symptoms.
Frequency can be divided into intermittent or persistent (more than four days per week and more than four weeks per year, respectively).
Severity can be divided into mild (symptoms do not interfere with quality of life) or severe (symptoms impact asthma control, sleep, sports participation, or school or work performance).
The International Primary Care Respiratory Group; British Society for Allergy and Clinical Immunology; and American Academy of Allergy, Asthma, and Immunology recommend intranasal corticosteroids alone for the initial treatment of persistent symptoms affecting quality of life and second-generation nonsedating antihistamines for mild intermittent disease.
Consider adding nasal irrigation or a decongestant for nasal congestion, ipratropium (Atrovent) or intranasal antihistamine for rhinorrhea, or intranasal antihistamine for persistent nasal ocular symptoms.
Use of nasal decongestants for longer than three days is not recommended because of possible rebound congestion.
