Seasonal Allergic Rhinitis Azelastine hydrochloride nasal spray Two Sprays Per Nostril Twice Daily Adverse experience information for azelastine hydrochloride nasal spray is derived from six placebo- and active- controlled, 2-day to 8-week clinical trials which included 391 patients, 12 years of age and older, with seasonal allergic rhinitis who received azelastine hydrochloride nasal spray at a dose of 2 sprays per nostril twice daily. In placebo-controlled efficacy trials, the incidence of discontinuation due to adverse reactions in patients receiving azelastine hydrochloride nasal spray and vehicle placebo was 2.2% and 2.8%, respectively. Table 1 contains adverse reactions that were reported with frequencies ≥2% in the azelastine hydrochloride nasal spray 2 sprays per nostril twice daily treatment group and more frequently than placebo.

The incidence of discontinuation due to adverse reactions in patients receiving azelastine hydrochloride nasal spray and vehicle placebo was 0.0% and 0.8%, respectively. Bitter taste was reported in 8.3% of patients compared to none in the placebo group. Somnolence was reported in 0.4% of patients compared to none in the placebo group. A total of 176 patients 5 to 11 years of age were exposed to azelastine hydrochloride nasal spray at a dose of 1 spray each nostril twice daily in 3 placebo-controlled studies. In these studies, adverse reactions that occurred more frequently in patients treated with azelastine hydrochloride nasal spray than with placebo, and that were not represented in the adult adverse reactions table above include rhinitis/cold symptoms (17.0% vs. 9.5%), cough (11.4% vs. 8.3%), conjunctivitis (5.1% vs. 1.8%), and asthma (4.5% vs. 4.1%). Adverse Reactions <2% in azelastine hydrochloride nasal spray One or Two Sprays Per Nostril Twice Daily The following reactions were observed infrequently (<2% and exceeding placebo incidence) in patients who received azelastine hydrochloride nasal spray dosed at 1 or 2 sprays per nostril twice daily in U.S. clinical trials.
