Treatment for Nasal Congestion
Intranasal corticosteroids are the most effective first-line medication for nasal congestion, particularly when associated with allergic rhinitis, with onset of action typically within 12 hours and superior efficacy compared to all other monotherapy options. 1
First-Line Therapy: Intranasal Corticosteroids
Intranasal corticosteroids (such as fluticasone propionate) are recommended as initial treatment for nasal congestion because they effectively control all major symptoms including congestion, sneezing, itching, and rhinorrhea. 2, 1, 3
These agents demonstrate superior efficacy compared to oral antihistamine-leukotriene antagonist combinations for seasonal and perennial allergic rhinitis. 2, 1
Onset of action occurs within 12 hours in most patients, though full benefit may require several days to weeks of continuous use. 2, 1
Local side effects are minimal when patients direct sprays away from the nasal septum, though nasal irritation and bleeding can occur if technique is improper. 2
The nasal septum should be examined periodically for mucosal erosions, as these may indicate increased risk for septal perforation (though this complication is rare). 2
Short-Term Rapid Relief: Topical Decongestants
Topical decongestants provide rapid relief and are appropriate for short-term use (maximum 3-5 days) for acute nasal congestion associated with viral infections, allergic rhinitis exacerbations, or eustachian tube dysfunction. 2, 1
The critical limitation is rhinitis medicamentosa (rebound congestion), which can develop in some patients after as little as 3 days of regular use, though others may tolerate 4-6 weeks without rebound. 2
Given this variability, instruct patients explicitly not to exceed 3-5 days of continuous use to minimize risk of medication-induced rhinitis. 2, 1, 4
Topical decongestants may assist delivery of other intranasal medications when significant mucosal edema is present. 2
Second-Line Oral Therapy: Oral Decongestants
Oral decongestants (pseudoephedrine 60 mg or phenylephrine) effectively reduce nasal congestion in both allergic and nonallergic rhinitis and provide benefit when combined with antihistamines. 2, 1, 5
Pseudoephedrine demonstrates objective efficacy in reducing nasal airway resistance with both single and multiple doses. 6
Common side effects include insomnia, appetite loss, irritability, palpitations, and small increases in systolic blood pressure and heart rate. 2, 1
Use with caution in hypertensive patients (monitoring is advised), and exercise particular caution in patients with arrhythmias or coronary artery disease. 2, 1
Avoid during first trimester of pregnancy due to reported fetal heart rate changes. 1
Combination Therapy Strategies
When intranasal corticosteroids alone provide insufficient relief, adding an intranasal antihistamine is recommended as the next step. 1
Oral antihistamine-decongestant combinations (such as desloratadine-pseudoephedrine) provide superior relief of nasal congestion compared to either component alone, particularly for patients with moderate-to-severe congestion. 7, 8
Intranasal anticholinergics (ipratropium bromide) combined with intranasal corticosteroids effectively reduce rhinorrhea but have minimal effect on congestion itself. 2, 1
Adjunctive Options
Nasal saline irrigation provides symptomatic relief with minimal adverse effects and is particularly useful for drug-induced nasal congestion. 1
Leukotriene receptor antagonists have similar efficacy to oral antihistamines but are less effective than intranasal corticosteroids; consider in patients with concurrent asthma. 2, 1
Second-generation oral antihistamines (loratadine, fexofenadine) are less effective for congestion than for other nasal symptoms and should not be used as monotherapy for congestion. 1
Critical Pitfalls to Avoid
Never use topical decongestants beyond 3-5 days continuously to prevent rhinitis medicamentosa. 2, 1, 4
Do not rely on first-generation antihistamines for congestion relief, as they are ineffective for nasal stuffiness when used alone. 9
If rhinitis medicamentosa develops, immediately discontinue topical decongestants and transition to intranasal corticosteroids. 4
Phenylephrine oral formulations have questionable efficacy due to extensive first-pass metabolism and lack of bioavailability at recommended doses. 9
