Things to help a runny nose

A runny nose happens when the nasal lining produces extra fluid. A cold, influenza or COVID-19 may cause drainage alongside sore throat, cough, fever or tiredness. Clear fluid with sneezing and itchy eyes can fit allergic rhinitis, including reactions to house dust mites or pets. Facial pressure, blocked breathing and thick mucus may occur with sinusitis. A runny nose alone cannot identify its cause.

Gently blow your nose and use a saline spray or rinse with water prepared according to the product instructions. Drink enough fluid to avoid a dry mouth, rest, and use a clean humidifier if dry air irritates you. Wash hands and avoid sharing towels when an infection is possible. Reduce exposure to smoke, strong scents, dust and a known allergy trigger. A pharmacist can explain whether an antihistamine or nasal treatment is suitable; follow the label and ask before giving medicines to a child.

Seek medical advice for trouble breathing, swelling of the face or throat, dehydration, severe facial pain, confusion, or a high or persistent fever. Arrange review when symptoms keep returning, last longer than expected, become one-sided with bleeding, or interfere with sleep. Testing may be advised when infection is suspected, especially after relevant exposure.

Ask whether the pattern suggests allergy or infection, which nasal products are appropriate, and how to reduce exposure to a suspected trigger.
