Etiology of Nasal Congestion and Rhinorrhea
The most common causes (see table ) are
Dry air may provoke congestion. Acute sinusitis Sinusitis Sinusitis is inflammation of the paranasal sinuses due to viral, bacterial, or fungal infections or allergic reactions. Symptoms include nasal obstruction and congestion, purulent rhinorrhea... read more is slightly less common, and a nasal foreign body Nasal Foreign Bodies Nasal foreign bodies are found occasionally in young children, the intellectually impaired, and patients with psychiatric conditions. Common objects pushed into the nose include cotton, paper... read more is unusual (and occurs predominantly in children).
Patients who use topical decongestants for > 3 to 5 days often experience significant rebound congestion when the effects of the decongestants wear off, causing them to continue using the decongestant in a vicious circle of persistent, worsening congestion. This situation (rhinitis medicamentosa) may persist for some time and may be misinterpreted as a continuation of the original problem rather than a consequence of treatment.
Evaluation of Nasal Congestion and Rhinorrhea
History of present illness should determine the nature of the discharge (eg, watery, mucoid, purulent, bloody) and whether discharge is chronic or recurrent. If recurrent, any relation to patient location, season, and exposure to potential triggering allergens (numerous) should be determined. A unilateral, clear, watery discharge, particularly after head trauma, can indicate a cerebrospinal fluid (CSF) leak. CSF discharge can also occur spontaneously in women who are in their 40s and have obesity, secondary to idiopathic intracranial hypertension Idiopathic Intracranial Hypertension Idiopathic intracranial hypertension causes increased intracranial pressure without a mass lesion or hydrocephalus, probably by obstructing venous drainage; cerebrospinal fluid composition is... read more .
Review of systems should seek symptoms of possible causes, including fever and facial pain (sinusitis); watery, itchy eyes (allergies); and sore throat, malaise, fever, and cough (viral upper respiratory infection [URI]).
Past medical history should seek known allergies and existence of diabetes or immunocompromise. Drug (prescription, over-the-counter, illicit) history should include asking specifically about topical decongestant use.
Vital signs are reviewed for fever.
Examination focuses on the nose and area over the sinuses. The face is inspected for focal erythema over the frontal and maxillary sinuses; these areas are also palpated for tenderness. Nasal mucosa is inspected for color (eg, red or pale), swelling, color and nature of discharge, and, particularly in children, the presence of a foreign body.
The following findings in patients with nasal congestion or rhinorrhea are of particular concern:
Unilateral discharge, particularly if purulent or bloody
Facial pain, tenderness, or both
Interpretation of findings
Symptoms and examination are often enough to suggest a diagnosis (see table ).
In children, unilateral foul-smelling discharge suggests a nasal foreign body Nasal Foreign Bodies Nasal foreign bodies are found occasionally in young children, the intellectually impaired, and patients with psychiatric conditions. Common objects pushed into the nose include cotton, paper... read more . If no foreign body is seen, sinusitis Sinusitis Sinusitis is inflammation of the paranasal sinuses due to viral, bacterial, or fungal infections or allergic reactions. Symptoms include nasal obstruction and congestion, purulent rhinorrhea... read more is suspected when purulent rhinorrhea persists for > 10 days along with fatigue and cough.
Testing is generally not indicated for acute nasal symptoms unless invasive sinusitis is suspected in a diabetic or immunocompromised patient; these patients usually require CT.
If a CSF leak is suspected, a sample of the discharge should be tested for the presence of beta-2 transferrin, which is highly specific for CSF.
Treatment of Nasal Congestion and Rhinorrhea
Specific conditions are treated. Topical or oral decongestants can relieve congestion. Topical decongestants include oxymetazoline, 2 sprays in each nostril once or twice a day for 3 days. Oral decongestants include pseudoephedrine 60 mg twice a day. Prolonged use of topical decongestants can cause rebound congestion, and prolonged use of oral decongestants can increase blood pressure and heart rate. Both should be avoided.
Viral rhinorrhea can be treated with first-generation oral antihistamines (eg, diphenhydramine 25 to 50 mg orally twice a day), which are recommended because of their anticholinergic properties unrelated to their H2-blocking properties.
Allergic congestion and rhinorrhea can be treated with antihistamines; in such cases, nonanticholinergic antihistamines (eg, fexofenadine 60 mg orally twice a day) as needed are used because they have fewer adverse effects. Nasal corticosteroids (eg, mometasone 2 sprays in each nostril daily) also help relieve symptoms.
Antihistamines and decongestants are not recommended for children < 6 years.
Geriatrics Essentials: Nasal Congestion and Rhinorrhea
Antihistamines, particularly first-generation antihistamines such as diphenhydramine, can have sedating and anticholinergic effects, and a decreased dosage should be used in older people. Similarly, sympathomimetics should be used with the lowest dosage that is clinically effective.
Most nasal congestion and rhinorrhea are caused by URIs or allergies.
Consider a foreign body in children.
Also consider rebound congestion due to topical decongestant overuse.
