Treatment of Rhinitis and Sinusitis

Medication Efficacy and Safety

Both medications effectively treat nasal inflammation, congestion, and other symptoms of rhinitis and sinusitis, according to the American Academy of Otolaryngology-Head and Neck Surgery 1
Using two corticosteroid nasal preparations may increase the risk of local side effects, including nasal irritation and bleeding, epistaxis, nasal septal perforation, pharyngitis, and headache, as reported by the Journal of Allergy and Clinical Immunology and the American Academy of Otolaryngology-Head and Neck Surgery 1, 2
Modern intranasal corticosteroids have minimal systemic absorption, but simultaneous use of two products could theoretically increase total systemic exposure, as noted by Rhinology 3
There is no evidence showing that combining two different intranasal corticosteroids provides superior efficacy compared to using a single agent at the appropriate dose, according to clinical guidelines from the American Academy of Otolaryngology-Head and Neck Surgery and the Journal of Allergy and Clinical Immunology 1, 2

When using intranasal corticosteroids, direct sprays away from the nasal septum to prevent repetitive direct application, and periodically examine the nasal septum to check for mucosal erosions, as recommended by the Journal of Allergy and Clinical Immunology 2
Proper technique is recommended to reduce the risk of local irritation or perforation, as advised by the Journal of Allergy and Clinical Immunology 2
Growth monitoring is recommended for children using intranasal corticosteroids, though most formulations have not shown significant effects on growth at recommended doses, according to the Journal of Allergy and Clinical Immunology 2

Nasal corticosteroids, including budesonide and fluticasone, are generally considered safe during pregnancy at recommended doses, according to Rhinology 3
The American Academy of Otolaryngology-Head and Neck Surgery recommends intranasal corticosteroids as the most effective medications for treating allergic rhinitis and nasal symptoms, and suggests considering adding a medication with a different mechanism of action if one intranasal corticosteroid is ineffective 1, 2
