Treatment of Nasal Congestion
Intranasal corticosteroids are the most effective first-line monotherapy for nasal congestion, with onset of action typically within 12 hours and maximum benefit achieved within 4-7 days. 1, 2
First-Line Treatment: Intranasal Corticosteroids
Intranasal corticosteroids (such as fluticasone propionate) should be initiated as primary therapy for nasal congestion, particularly when associated with allergic or non-allergic rhinitis, as they are more effective than oral antihistamine-leukotriene receptor antagonist combinations. 3, 1
The recommended starting dose for adults is 200 mcg daily (two 50-mcg sprays per nostril once daily), which can be administered as a single daily dose or divided into 100 mcg twice daily. 2
For pediatric patients aged 4 years and older, initiate treatment with 100 mcg daily (one spray per nostril once daily), reserving 200 mcg daily for inadequate responders. 2
Patients must understand that full therapeutic benefit may take up to 2 weeks, though symptom improvement often begins within 12 hours, and they should continue regular use rather than discontinuing prematurely. 3, 2
Local side effects are minimal but include nasal irritation and epistaxis; nasal septal perforation is rare. 3
Short-Term Adjunctive Therapy: Topical Decongestants
Topical nasal decongestants (oxymetazoline, xylometazoline) provide rapid relief and should be limited to 3-5 consecutive days maximum to prevent rhinitis medicamentosa (rebound congestion). 3, 1
Recent evidence suggests that oxymetazoline used for up to 7 days (400 μg total daily dose) and xylometazoline for up to 10 days (840 μg total daily dose) do not cause rebound congestion when used at recommended dosing. 4
Topical decongestants may facilitate delivery of intranasal corticosteroids when significant mucosal edema is present. 3
If rhinitis medicamentosa develops, topical decongestants must be stopped immediately. 3, 5
Second-Line Options: Oral Decongestants
Oral decongestants (pseudoephedrine, phenylephrine) reduce nasal congestion through systemic α-adrenergic agonism but cause side effects including insomnia, irritability, and palpitations. 3, 1
Use oral decongestants with extreme caution in patients with cardiac arrhythmias, angina, cerebrovascular disease, hypertension, bladder neck obstruction, glaucoma, or hyperthyroidism. 3
Pseudoephedrine is associated with small increases in systolic blood pressure and heart rate. 1
Oral decongestants should be avoided in older adults and young children due to increased risk of adverse effects. 3
Adjunctive Therapies
Nasal Saline Irrigation
Nasal saline irrigation (buffered hypertonic 3-5% solution preferred) provides symptomatic relief with minimal adverse effects and may improve quality of life, particularly in patients with frequent sinusitis. 3, 1
Saline irrigation is beneficial as monotherapy or combined with other treatments for chronic rhinosinusitis. 3
Intranasal Antihistamines
Intranasal antihistamines (azelastine) are equal to or superior to oral second-generation antihistamines and have clinically significant effects on nasal congestion. 3
Combining intranasal antihistamines with intranasal corticosteroids may provide additional benefit, particularly for mixed rhinitis, though the optimal interval between administrations is not established. 3, 1
Intranasal Anticholinergics
Ipratropium bromide effectively reduces rhinorrhea but has no effect on nasal congestion or other nasal symptoms. 3, 1
Concomitant use with intranasal corticosteroids is more effective for rhinorrhea than either agent alone without increased adverse events. 3
Oral Antihistamines
Second-generation oral antihistamines (loratadine, fexofenadine, desloratadine) are less effective for nasal congestion compared to other nasal symptoms. 1
Antihistamines have no role in symptomatic relief of acute bacterial rhinosinusitis in non-atopic patients and may worsen congestion by drying nasal mucosa. 3
In allergic patients, antihistamines combined with oral decongestants provide more effective congestion relief than antihistamines alone. 3
Leukotriene Receptor Antagonists
- Oral leukotriene receptor antagonists (montelukast) have similar efficacy to oral antihistamines and may be particularly useful in patients with both rhinitis and asthma. 3, 1
Treatment Algorithm
For allergic rhinitis with congestion:
- Start intranasal corticosteroids as first-line therapy (200 mcg daily for adults, 100 mcg daily for children ≥4 years). 1, 2
- If immediate relief needed, add short-term topical decongestant (maximum 3-5 days). 1
- If symptoms persist after 4-7 days, add intranasal antihistamine. 1
- Consider oral decongestant if topical therapy contraindicated, with appropriate patient screening for contraindications. 1
For acute congestion (common cold, acute rhinosinusitis):
- Short-term topical decongestant (3-5 days maximum) for rapid relief. 3, 1
- Nasal saline irrigation for symptomatic relief. 3
- Analgesics (NSAIDs, acetaminophen) for associated facial pain. 3
- Avoid antihistamines in non-allergic patients as they provide no benefit and may worsen congestion. 3
For non-allergic rhinitis:
- Intranasal corticosteroids remain effective for vasomotor rhinitis and NARES. 3
- Ipratropium bromide specifically for rhinorrhea component. 3
- Oral decongestants (pseudoephedrine) reduce nasal congestion in vasomotor rhinitis. 3
Critical Pitfalls to Avoid
Never recommend prolonged use of topical decongestants beyond 3-5 days due to risk of rhinitis medicamentosa, though recent evidence suggests slightly longer durations may be safe at recommended doses. 3, 5, 4
Do not prescribe first-generation antihistamines without counseling patients about sedation, performance impairment, and anticholinergic effects; second-generation agents are preferred. 3
Avoid oral corticosteroids for routine nasal congestion; reserve short courses (5-7 days) only for very severe or intractable symptoms. 3
Do not use antibiotics for symptomatic relief of nasal congestion in acute rhinosinusitis, as they do not improve congestion symptoms. 3
