Treatment of Chronic Nasal Congestion

First-Line Treatments

The American Academy of Otolaryngology-Head and Neck Surgery recommends intranasal corticosteroids as the most effective first-line treatment for chronic nasal congestion, providing superior symptom relief compared to other therapies 1
Intranasal corticosteroids provide effective relief for all symptoms of seasonal and perennial allergic rhinitis, including nasal congestion, according to the Journal of Allergy and Clinical Immunology 2
Saline nasal irrigation is a highly effective adjunctive therapy with minimal side effects, providing benefits such as improved mucous clearance and enhanced ciliary activity, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 3

The Journal of Allergy and Clinical Immunology recommends second-generation antihistamines as generally preferred over first-generation antihistamines for treating chronic nasal congestion 5
Intranasal antihistamines may be considered as first-line treatment for allergic and nonallergic rhinitis, and have a clinically significant effect on nasal congestion, according to the Journal of Allergy and Clinical Immunology 6
Oral decongestants can reduce nasal congestion but may cause side effects, and should be used with caution in patients with hypertension, cardiovascular disease, glaucoma, or hyperthyroidism, as recommended by the Journal of Allergy and Clinical Immunology 6

For allergic rhinitis, intranasal corticosteroids are recommended as first-line therapy, and second-generation antihistamines may be added if the allergic component is significant, according to the American Academy of Otolaryngology-Head and Neck Surgery 1
For chronic rhinosinusitis, intranasal corticosteroids plus saline irrigation are the foundation therapy, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 3, 1

Using topical decongestants for more than 3-5 days can lead to rebound congestion, and relying on antihistamines alone for nasal congestion is often inadequate, according to the American Academy of Otolaryngology-Head and Neck Surgery 1
Discontinuing intranasal corticosteroids too early when symptoms improve can lead to recurrence, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 1
Surgery may be considered for patients with documented chronic sinus infection refractory to medical therapy, or for nasal obstruction from severe nasal septal deviation, inferior turbinate hypertrophy, adenoidal hypertrophy, or refractory sinusitis, according to the Journal of Allergy and Clinical Immunology 6
