Treatment of Severe Allergic Rhinitis with Azelastine-Fluticasone Combination

Efficacy Comparison

The combination of azelastine plus fluticasone nasal spray provides greater nasal symptom reduction than budesonide spray alone for symptom reduction in patients with moderate-to-severe allergic rhinitis 1, 2, 3
The combination of fluticasone propionate plus azelastine provides greater nasal symptom reduction than either agent alone or placebo, with symptom score reductions of -5.31 to -5.7 compared to -3.84 to -5.1 for fluticasone alone 1, 2
Studies show the azelastine-fluticasone combination provides a 40% relative improvement in symptom reduction compared to either agent used as monotherapy 2
When comparing individual agents, intranasal corticosteroids are generally more effective than intranasal antihistamines like azelastine for controlling nasal symptoms 3

The 2017 Joint Task Force on Practice Parameters provides a weak recommendation for using the combination of an intranasal corticosteroid and an intranasal antihistamine for initial treatment of moderate-to-severe seasonal allergic rhinitis 2, 3
Intranasal corticosteroids remain the most effective single medication class for controlling allergic rhinitis symptoms 4, 5
The weak recommendation for combination therapy reflects concerns about potential bias in available studies, lack of studies on add-on therapy, and consideration of side effects and cost 3

The combination therapy has a low rate of adverse events 2, 3
Dysgeusia is the most common adverse event with azelastine, occurring in patients 3
Epistaxis rates with the combination therapy are similar to or lower than placebo 3
Somnolence occurs in patients using azelastine-containing treatments 3

For moderate-to-severe allergic rhinitis, consider azelastine-fluticasone combination spray as first-line therapy, providing superior symptom control compared to either agent alone 2, 3
If combination therapy is unavailable or not tolerated, an intranasal corticosteroid like budesonide is the preferred monotherapy 4
For patients with ocular symptoms, the azelastine-fluticasone combination provides better relief than fluticasone alone 2, 3

The quality of life improvement with combination therapy does not consistently exceed the minimal clinically important difference compared to monotherapies 3
The added cost of using two medications must be considered when recommending combination therapy 3
Most studies evaluated fluticasone rather than budesonide in combination with azelastine, though both are intranasal corticosteroids 1, 2
