Seasonal Allergic Rhinitis Azelastine Hydrochloride Nasal Solution Two Sprays Per Nostril Twice Daily Adverse experience information for azelastine hydrochloride nasal solution 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 solution 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 solution 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 solution 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 solution and vehicle placebo was 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 solution 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 solution than with placebo, and that were not represented in the adult adverse reactions table above include rhinitis/cold symptoms (17% 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 Solution 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 solution dosed at 1 or 2 sprays per nostril twice daily in U.S.
clinical trials.
Cardiovascular: flushing, hypertension, tachycardia.
Dermatological: contact dermatitis, eczema, hair and follicle infection, furunculosis, skin laceration.
Digestive: constipation, gastroenteritis, glossitis, ulcerative stomatitis, vomiting, increased SGPT, aphthous stomatitis, diarrhea, toothache.
Metabolic and Nutritional: increased appetite.
Musculoskeletal: myalgia, temporomandibular dislocation, rheumatoid arthritis.
Neurological: hyperkinesia, hypoesthesia, vertigo.
Psychological: anxiety, depersonalization, depression, nervousness, sleep disorder, thinking abnormal.
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.
Urogenital: albuminuria, amenorrhea, breast pain, hematuria, increased urinary frequency.
Whole Body: allergic reaction, back pain, herpes simplex, viral infection, malaise, pain in extremities, abdominal pain, pyrexia.
Vasomotor Rhinitis Adverse experience information for azelastine hydrochloride nasal solution is derived from two placebo-controlled clinical studies which included 216 patients 12 years and older with vasomotor rhinitis who received azelastine hydrochloride nasal solution 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 azelastine hydrochloride nasal solution and vehicle placebo was 2.8% and 2.9%, respectively.
The following adverse reactions were reported with frequencies ≥ 2% in the azelastine hydrochloride nasal solution treatment group and more frequently than placebo.

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.
6.2 Postmarketing Experience During the post approval use of azelastine hydrochloride nasal solution, the following adverse reactions have been identified.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Adverse reactions reported include: anaphylaxis, 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.
The most common adverse reactions (≥2% incidence) are: bitter taste, headache, somnolence, dysesthesia, rhinitis, nasal burning, pharyngitis, epistaxis, sinusitis, paroxysmal sneezing, nausea, dry mouth, fatigue, dizziness, and weight increase.
