Seasonal allergy relief: what to know

Seasonal allergy relief usually combines reducing allergen exposure with a treatment plan matched to your symptoms and health history. A blocked or runny nose, sneezing, itchy eyes, cough and tiredness can make daily activities harder. Relief may come from environmental changes, saline rinsing, or medicines recommended by a pharmacist or clinician.

Allergic symptoms begin when the immune system reacts to particles such as pollen or mould. Avoiding every trigger is rarely practical, but limiting exposure can reduce the amount reaching the eyes and airways. Closing windows during dusty or high-pollen conditions, changing clothes after outdoor time, and rinsing the face can be useful. Symptoms that continue outside a particular season may point to an indoor trigger or another condition.

Nasal symptoms and eye symptoms can occur together, while coughing or wheezing may signal airway involvement. Explore [Allergic Rhinitis](/conditions/allergic-rhinitis/) and [Allergic Conjunctivitis](/conditions/allergic-conjunctivitis/) for related explanations.

Use a saline nasal spray or rinse only as directed, and use clean water and equipment for a rinse. A pharmacist can advise on an antihistamine or nasal spray, taking account of pregnancy, age, glaucoma, blood pressure, other medicines and medical conditions. Follow the product instructions; some decongestant sprays can worsen blockage when used for too long. Keep a symptom diary to identify outdoor places, times and activities linked with flares.

Book a clinical review when symptoms disturb sleep, work or exercise, keep returning despite sensible measures, or are difficult to distinguish from infection. Seek urgent help for swelling of the lips or tongue, faintness, severe breathing difficulty, or rapidly worsening wheeze. A persistent cough may need assessment rather than repeated self-treatment; see [Chronic Cough](/conditions/chronic-cough/) for context.

Ask which trigger is most plausible, whether your current medicines are suitable, how long to try a treatment, and which symptoms would suggest asthma, sinusitis or another diagnosis.
