Understanding Allergic Rhinitis (Hay Fever) and How to Manage It
Allergic rhinitis, commonly known as hay fever, is an inflammation of the nasal passages caused by allergens. Symptoms include sneezing, runny or itchy nose, itchy eyes or throat, congestion, and sometimes coughing, headaches, or wheezing. Allergic rhinitis can be seasonal, triggered by pollen from trees, grasses, or weeds, or persistent, caused by year-round allergens like dust mites or pet dander. About 20% of Canadians experience this condition.
Mild symptoms may not interfere with daily life, while moderate to severe cases can affect work, school, and sleep. Avoiding allergens is the best prevention, but when this isn’t possible, medications can provide effective relief.
Treatment options include:
- Oral antihistamines (e.g., cetirizine, loratadine, fexofenadine) – many are non-drowsy.
- Nasal sprays – corticosteroids (e.g., fluticasone, budesonide) for moderate to severe symptoms, or anticholinergics (e.g., ipratropium) for runny noses.
- Eye drops – antihistamine drops (e.g., olopatadine) for itchy eyes.
- Other options – saline sprays, sodium cromoglycate, or montelukast for persistent or hard-to-treat cases.
Treatment choice depends on symptom severity, triggers, medical history, and individual response. Pregnant or breastfeeding women and children should consult a healthcare professional before starting treatment. Proper management can significantly improve comfort and quality of life during allergy season.
