Home remedies to stop a runny nose

The nose makes mucus to trap particles and protect its lining. A cold or influenza can increase mucus, while allergic rhinitis may cause watery discharge, sneezing, and itchy eyes. Pet allergens, house-dust mites, smoke, cold air, and spicy foods can also trigger symptoms. COVID-19 may include a runny nose alongside other respiratory symptoms.

Blow your nose gently, one nostril at a time, and use soft tissues to reduce skin soreness. Saline spray can moisturise the nasal lining. Drink enough to avoid dehydration, wash your hands, and rest if you feel unwell. Reduce exposure to smoke, perfume, dust, and a known allergy trigger. A pharmacist can explain whether an antihistamine or another product is appropriate; do not share medicines or use a child’s product without guidance.

Contact a clinician if the discharge persists, keeps returning without an obvious trigger, or comes with facial pain, fever, wheezing, or worsening cough. Seek urgent help for trouble breathing, blue lips, severe drowsiness, or signs of dehydration. If infection is possible, follow local advice about testing and limiting close contact with vulnerable people.

Does the pattern suggest an allergy or infection? Which medicine is safe with my current treatment? What should I do if the discharge becomes thick, bloody, or one-sided?
