What is good for a runny nose?

A runny nose happens when the nasal lining produces extra mucus. A common cold or influenza may also bring cough, sore throat, tiredness, or fever. Allergic rhinitis often causes repeated sneezing, itching, and watery eyes after exposure to pollen or another trigger; pet allergy and house dust mite allergy can produce similar patterns.

COVID-19 can include nasal symptoms alongside other respiratory symptoms. Sinusitis is more likely to involve facial pressure, blocked passages, or thick discharge. These patterns overlap, so a runny nose alone cannot identify the cause.

Use a sterile saline spray or a properly prepared saline rinse, blow your nose gently, drink fluids, and rest. Wash your hands after wiping or blowing your nose, and avoid sharing towels or utensils when an infection is possible. Keep away from smoke and strong fragrances that can prolong irritation.

If allergies seem responsible, reduce exposure to the suspected trigger and ask a pharmacist about an appropriate allergy medicine. Check combination cold products carefully, particularly if you have high blood pressure, are pregnant, or take other medicines.

Arrange medical advice if symptoms are severe, keep worsening, last longer than expected, or repeatedly return without an obvious trigger. Seek urgent help for breathing difficulty, swelling of the face or throat, severe headache with a stiff neck, confusion, dehydration, chest pain, or a high fever with marked weakness. A one-sided bloody discharge after an injury also needs prompt assessment.

Ask whether your symptoms fit an allergy, cold, influenza, COVID-19, or sinus problem; whether testing is useful; and which nasal treatment suits your health history. Mention fever, facial pain, breathing symptoms, exposures, and how long the discharge has continued.
