Medicine to stop a runny nose in adults

A clear, watery runny nose with sneezing or itchy eyes can occur with allergic rhinitis, including reactions to pets or house dust mites. A common cold, influenza or COVID-19 may bring nasal discharge with cough, sore throat, tiredness or fever. Sinusitis is more likely to need assessment when facial pressure, blocked drainage or thick discharge persists or worsens. The nasal symptom by itself cannot identify the cause.

Saline spray or rinse can wash away mucus and irritants; use clean, prepared water for a rinse and follow the product instructions. Rest, drink regularly and avoid smoke. For an allergy pattern, a pharmacist may recommend an antihistamine or nasal treatment after checking blood pressure, glaucoma, prostate symptoms, pregnancy and other medicines. Decongestant sprays should only be used for the directed short period because overuse can worsen blockage. Check combination cold remedies carefully so ingredients are not doubled.

Seek urgent help for severe breathing difficulty, confusion, faintness, swelling of the face or a sudden severe headache. Arrange medical advice for persistent high fever, severe facial pain, swelling around an eye, blood-stained discharge, symptoms after a head injury, or a runny nose that does not settle. Consider infection precautions and testing advice when respiratory symptoms could fit COVID-19 or influenza.

Tell your clinician whether the discharge is clear or coloured, how long it has lasted, and whether you have fever, facial pain, itchy eyes or breathing symptoms. Ask which product fits your conditions and medicines, and how long to use it.
