Allergic Rhinitis Treatment Guidelines

Introduction to Antihistamine Options

The American Academy of Allergy, Asthma, and Immunology recommends second-generation antihistamines over first-generation antihistamines for the treatment of allergic rhinitis due to their improved safety profile and reduced sedative effects 1, 2, 3

Second-generation antihistamines effectively reduce rhinorrhea, sneezing, and itching associated with allergic rhinitis but have limited effect on nasal congestion 4
Fexofenadine, loratadine, and desloratadine do not cause sedation at recommended doses, according to the American College of Allergy, Asthma, and Immunology 2, 3
Continuous treatment for seasonal or perennial allergic rhinitis is more effective than intermittent use, as stated by the American Academy of Allergy, Asthma, and Immunology 4, 3

Intranasal antihistamines may be considered for use as first-line treatment for both allergic and nonallergic rhinitis, according to the American College of Allergy, Asthma, and Immunology 2
Intranasal antihistamines are efficacious and equal to or superior to oral second-generation antihistamines for treatment of seasonal allergic rhinitis, as recommended by the American Academy of Allergy, Asthma, and Immunology 2, 5
Intranasal antihistamines have been associated with a clinically significant effect on nasal congestion, unlike oral antihistamines, as stated by the American College of Allergy, Asthma, and Immunology 2, 5

First-generation antihistamines should be avoided in children under 6 years due to safety concerns, according to the American Academy of Pediatrics 3
Older adults are more sensitive to the psychomotor impairment from antihistamines, making second-generation options strongly preferred, as recommended by the American Geriatrics Society 3

First-generation antihistamines can cause performance impairment even when patients don't feel drowsy, according to the National Sleep Foundation 3
Don't assume all second-generation antihistamines have the same sedation profile; there are important differences, as stated by the American College of Allergy, Asthma, and Immunology 2, 3
Intranasal corticosteroids are more effective than antihistamines for controlling the full spectrum of allergic rhinitis symptoms, especially when nasal congestion is prominent, according to the American Academy of Allergy, Asthma, and Immunology 1, 3
