Astelin® Nasal Spray Two Sprays Per Nostril Twice Daily
Adverse experience information for Astelin® Nasal Spray is derived from six well-controlled, 2-day to 8-week clinical studies which included 391 patients who received Astelin® 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 Astelin® Nasal Spray was not different from vehicle placebo (2.2% vs 2.8%, respectively). In these clinical studies, adverse events that occurred more often in patients treated with Astelin® Nasal Spray versus vehicle placebo included bitter taste (19.7% vs. 0.6%), somnolence (11.5% vs. 5.4%), weight increase (2.0% vs. 0%), and myalgia (1.5% vs. 0%).
The following table contains adverse events that were reported with frequencies 2% in the Astelin® Nasal Spray 2 sprays per nostril twice daily treatment group and more frequently than placebo in short-term ( 2 days) and long-term (2-8 weeks) clinical trials.

Astelin® Nasal Spray One Spray Per Nostril Twice Daily
Adverse experience information for Astelin® Nasal Spray at a dose of one spray per nostril twice daily is derived from two placebo- controlled 2-week clinical studies which included 276 patients. None of the patients receiving Astelin® Nasal Spray were discontinued from these studies due to adverse reactions. Three patients receiving vehicle placebo were discontinued due to adverse reactions. 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 12 years of age were exposed to Astelin® Nasal Spray at a dose of 1 spray each nostril twice daily in 3 placebo-controlled studies. In these studies, adverse events that occurred more frequently in patients treated with Astelin® Nasal Spray than with placebo, and that were not represented in the adult adverse event 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%).
The following events were observed infrequently ( < 2% and exceeding placebo incidence) in patients who received Astelin® Nasal Spray dosed at 1 or 2 sprays per nostril twice daily in U.S. clinical trials.
Metabolic and Nutritional: increased appetite.
Musculoskeletal: myalgia, temporomandibular dislocation, rheumatoid arthritis.
Neurological: hyperkinesia, hypoesthesia, vertigo.
Respiratory: bronchospasm, coughing, throat burning, laryngitis, bronchitis, dry throat, nocturnal dyspnea, nasopharyngitis, nasal congestion, pharyngolaryngeal pain, sinusitis, nasal dryness, paranasal sinus hypersecretion, post nasal drip.
Special Senses: conjunctivitis, eye abnormality, eye pain, watery eyes, taste loss.
Adverse experience information for Astelin® Nasal Spray is derived from two placebo-controlled clinical studies which included 216 patients who received Astelin® Nasal Spray at a dose of 2 sprays per nostril twice daily for up to 28 days. The incidence of discontinuation due to adverse reactions in patients receiving Astelin® Nasal Spray was not different from vehicle placebo (2.8% vs 2.9%, respectively).
The following adverse events were reported with frequencies 2% in the Astelin® Nasal Spray treatment group and more frequently than placebo.

Events observed infrequently ( < 2% and exceeding placebo incidence) in patients who received Astelin® Nasal Spray (2 sprays/ nostril twice daily) in U.S. clinical trials in vasomotor rhinitis were similar to those observed in U.S. clinical trials in seasonal allergic rhinitis.
In controlled trials involving nasal and oral azelastine hydrochloride formulations, there were infrequent occurrences of hepatic transaminase elevations. The clinical relevance of these reports has not been established.
In addition, the following spontaneous adverse events have been reported during the marketing of Astelin® Nasal Spray and causal relationship with the drug is unknown: anaphylactoid reaction, application site irritation, atrial fibrillation, chest pain, confusion, dyspnea, facial edema, involuntary muscle contractions, nasal sores, palpitations, paresthesia, parosmia, pruritus, rash, disturbance or loss of sense of smell and/or taste, tolerance, urinary retention, vision abnormal and xerophthalmia.

Concurrent use of Astelin® Nasal Spray with alcohol or other CNS depressants should be avoided because additional reductions in alertness and additional impairment of CNS performance may occur.
Cimetidine (400 mg twice daily) increased the mean Cmax and AUC of orally administered azelastine hydrochloride (4 mg twice daily) by approximately 65%. Ranitidine hydrochloride (150 mg twice daily) had no effect on azelastine pharmacokinetics. Interaction studies investigating the cardiac effects, as measured by the corrected QT interval (QTc), of concomitantly administered oral azelastine hydrochloride and erythromycin or ketoconazole were conducted. Oral erythromycin (500 mg three times daily for seven days) had no effect on azelastine pharmacokinetics or QTc based on analyses of serial electrocardiograms. Ketoconazole (200 mg twice daily for seven days) interfered with the measurement of azelastine plasma concentrations; however, no effects on QTc were observed.
No significant pharmacokinetic interaction was observed with the coadministration of an oral 4 mg dose of azelastine hydrochloride twice daily and theophylline 300 mg or 400 mg twice daily.
