Runny nose

When to make a doctor’s appointment

See a doctor if:

• Lasts more than 10 days
• High fever
• Green nasal discharge with pain or fever
• Also have asthma or emphysema or taking immune-suppressing medications
• Blood in nasal discharge or a persistent clear discharge after a head injury

Self-care

Self-care options include drinking plenty of water and using a humidifier. Over-the-counter non-sedating antihistamines may help a runny nose caused by allergies.
