Management of Adult Nasal Congestion

Primary Treatment Options

The American Academy of Otolaryngology recommends oral decongestants, such as pseudoephedrine 60 mg every 4-6 hours, as the most effective first-line treatment for adult nasal congestion, with combination antihistamine-decongestant therapy providing superior relief when multiple symptoms are present 1
Pseudoephedrine is the preferred oral decongestant, safe for short-term use in normotensive adults with minimal blood pressure elevation, according to the Journal of Allergy and Clinical Immunology 2, 3
Alternative oral decongestants, such as phenylephrine, are available, although pseudoephedrine shows superior efficacy, as noted by the Journal of Allergy and Clinical Immunology 2, 4

The American Academy of Otolaryngology suggests that combination antihistamine-decongestant therapy, such as desloratadine 5 mg + pseudoephedrine 240 mg once daily, provides greater overall symptom relief than monotherapy and is particularly effective when congestion accompanies other rhinitis symptoms 1, 2
Second-generation antihistamines, such as cetirizine, loratadine, and fexofenadine, can be combined with pseudoephedrine for enhanced effect, according to the Journal of Allergy and Clinical Immunology 2, 4

Topical decongestants, such as oxymetazoline and xylometazoline, provide rapid relief but must be limited to 3 days maximum to prevent rhinitis medicamentosa, as warned by the Journal of Allergy and Clinical Immunology and the American Academy of Otolaryngology-Head and Neck Surgery 2, 4, 6, 7

Intranasal corticosteroids, such as fluticasone, mometasone, and budesonide, are the most effective medication class for allergic rhinitis with congestion, superior to all other monotherapies, according to the Journal of Allergy and Clinical Immunology 2, 8
The American Academy of Otolaryngology recommends using intranasal corticosteroids with caution, as they may cause bleeding, and suggests directing the spray away from the nasal septum to minimize this risk 2, 4, 6

Combination antihistamine-decongestant-analgesic products have general benefit for common cold in adults, and paracetamol (acetaminophen) may provide modest additional relief for nasal obstruction when combined with decongestants, as noted by the American Academy of Otolaryngology and the Journal of Allergy and Clinical Immunology 1, 10
Nasal saline irrigation can be used adjunctively for symptomatic relief, according to the American Academy of Otolaryngology and the American Academy of Otolaryngology-Head and Neck Surgery 1, 7
