| Definition | Nasal discharge is any mucus-like material that comes out of the nose. |
| Alternative Names | Runny nose; Postnasal drip; Rhinorrhea; Coryza |
| Considerations | Rhinorrhea is common, but rarely serious. Nasal discharges can include drainage from inflamed or infected sinuses, in which case it may be thick or discolored. Problems from the runny nose are the result of excess mucus production. The mucus may cause postnasal drip and/or cough that is usually worse at night. A sore throat may also result from excessive mucus drainage. The mucus drip may plug up the tube between the nose and the ear, causing an ear infection and pain. The mucus drip may also plug the sinus passages, causing sinus infection and pain. |
| Common Causes | The common cold or the flu (nasal secretions contain antibodies that act against viruses and carry them out of the body) Allergies , allergic rhinitis , or hay fever (nasal secretions are usually clear and very thin -- see information on Allergy to mold, dander, dust ) Sinusitis (the nasal secretions may be thick and discolored yellow, brown, or green) Head injury Bacterial infections (may cause a rusty or green discharge) Small objects in the nostril (especially in children) Nasal sprays or drops containing vasoconstrictors may cause rebound rhinorrhea, if used longer than 3 consecutive days |
| Home Care | Increasing the humidity in the air with a vaporizer or humidifier helps thin or liquefy the mucus. Heated air inside a house is usually very dry -- cooler air contains more moisture, and is preferable. Keeping the mucus thin (rather than thick and sticky) will help prevent complications, such as ear and sinus infections, and will help prevent plugging of the nasal passages. One way to do this is by using saline nasal sprays. Drinking extra fluids also helps to thin nasal secretions. Because of the complications of medications, runny noses should be treated only when the discomfort is moderate to extreme. Antihistamines (to block allergic reactions and decrease the amount of secretion), decongestants (to shrink the mucus membranes), analgesics , or antipyretics can provide some relief. Don't use over-the-counter nasal sprays more frequently than 3 days on and 3 days off, unless ordered by the doctor. Be aware that decongestants make some children overly active, and that antihistamines may cause drowsiness , as well as interfere with sleep. |
