What should you know about consistent sneezing?

Sneezing is a protective reflex that clears particles from the nose. Allergic rhinitis can cause repeated sneezing with an itchy or blocked nose and watery eyes. House dust mite allergy or pet allergy may produce symptoms in particular rooms or after contact. A common cold may bring sneezing with a runny nose, sore throat or cough. Smoke, perfume, cleaning products and dry air can also irritate the nasal lining without an allergy.

Notice when sneezing starts, where you are, and whether dust, animals, fragrance or outdoor air is present. Wash hands, reduce indoor dust, ventilate rooms and avoid smoke. Saline nasal rinsing may help clear irritants when used with safe, clean water and proper equipment. A pharmacist can discuss suitable allergy medication, especially if congestion or itching is interfering with sleep or work. Do not start several new products at once, because that can make it harder to identify what helps.

Arrange a medical review if sneezing continues despite avoiding likely triggers, repeatedly disrupts sleep, or comes with persistent blockage, facial pain, fever or reduced sense of smell. Seek urgent help for swelling of the lips or tongue, wheezing, difficulty breathing, faintness or rapidly worsening symptoms. A clinician can examine the nose and consider whether the pattern fits allergic rhinitis, a common cold or another cause.

Ask which triggers are most plausible, whether your symptoms suggest allergy testing, and which treatment is suitable with your other medicines. Mention any asthma, eczema, new household exposures and the effect on sleep.
