Quick remedy for a runny nose

A runny nose occurs when the nasal lining makes extra fluid. A common cold may bring congestion, sneezing or a sore throat. Allergic rhinitis can cause repeated sneezing, itching and watery discharge after exposure to pollen, dust or animals. Sinusitis may cause facial pressure and thicker mucus. A runny nose can also occur with influenza or COVID-19, especially when other respiratory symptoms are present. The symptom alone does not identify its cause.

Use a saline spray or rinse made with safe, prepared water, and clean the device as directed. Blow your nose gently, one side at a time, to reduce pressure and irritation. Drink enough fluid to avoid a dry mouth and rest if you feel unwell. Wash your hands and avoid sharing towels when an infection is possible. If dust, pets or another exposure clearly triggers symptoms, reduce contact and ask a pharmacist about suitable treatment. Do not use decongestant nasal sprays for longer than the product instructions allow.

Seek urgent help for trouble breathing, swelling of the lips or tongue, confusion, severe weakness or signs of dehydration. Arrange a medical review when symptoms are severe, keep returning, last longer than expected, or come with persistent fever, facial pain, one-sided foul-smelling discharge or worsening headache. A clinician can distinguish allergy from infection and check whether another nasal problem is involved.

Ask whether your pattern fits an allergy, viral illness or sinus problem, which saline product is appropriate, and whether an antihistamine or nasal treatment is suitable for you. Mention your other medicines, pregnancy, asthma and any breathing symptoms.
