Systemic and local corticosteroid use may result in the following:

  • Somnolence [see WARNINGS AND PRECAUTIONS]
  • Local nasal effects, including epistaxis, nasal ulceration, nasal septal perforation, impaired wound healing, and Candida albicans infection [see WARNINGS AND PRECAUTIONS]
  • Glaucoma and cataracts [see WARNINGS AND PRECAUTIONS]
  • Immunosuppression [see WARNINGS AND PRECAUTIONS]
  • Hypothalamic-pituitary-adrenal (HPA) axis effects, including growth reduction [see WARNINGS AND PRECAUTIONS, Use in Specific Populations]

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect rates observed in practice.

Adults and Adolescents 12 Years of Age and Older

The safety data described below in adults and adolescents 12 years of age and older reflect exposure to DYMISTA in 853 patients (12 years of age and older; 36% male and 64% female) with seasonal allergic rhinitis in 3 double-blind, placebo-controlled clinical trials of 2-week duration. The racial distribution for the 3 clinical trials was 80% white, 16% black, 2% Asian, and 1% other.

In the 3 placebo controlled clinical trials of 2-week duration, 3411 patients with seasonal allergic rhinitis were treated with 1 spray per nostril of DYMISTA, azelastine hydrochloride nasal spray, fluticasone propionate nasal spray, or placebo, twice daily. The azelastine hydrochloride and fluticasone propionate comparators use the same vehicle and device as DYMISTA and are not commercially marketed. Overall, adverse reactions were 16% in the DYMISTA treatment groups, 15% in the azelastine hydrochloride nasal spray groups, 13% in the fluticasone propionate nasal spray groups, and 12% in the placebo groups. Overall, 1% of patients in both the DYMISTA and placebo groups discontinued due to adverse reactions.

Table 1 contains adverse reactions reported with frequencies greater than or equal to 2% and more frequently than placebo in patients treated with DYMISTA in the seasonal allergic rhinitis controlled clinical trials.

In the above trials, somnolence was reported in < 1% of patients treated with DYMISTA (6 of 853) or vehicle placebo (1 of 861) [see WARNINGS AND PRECAUTIONS].

Pediatric Patients 6-11 Years of Age

The safety data described below in children 6-11 years of age reflect exposure to DYMISTA in 152 patients (6-11 years of age; 57% male and 43% female) with seasonal allergic rhinitis in one double-blind, placebo-controlled clinical trial of 2-week duration. The racial distribution for the clinical trial was 69% white, 31% black, 2% Asian and 2% other.

In the placebo-controlled clinical trial of 2-week duration, patients with seasonal allergic rhinitis were treated with 1 spray per nostril of DYMISTA or placebo, twice daily. Overall, adverse reactions were 16% in the DYMISTA treatment group, and 12% in the placebo group. Overall, 1% of patients in both the DYMISTA and placebo groups discontinued due to adverse reactions.

Table 2 contains adverse reactions reported with frequencies greater than or equal to 2% and more frequently than placebo in patients treated with DYMISTA in the seasonal allergic rhinitis controlled clinical trial.

In the above trial, somnolence was not reported [see WARNINGS AND PRECAUTIONS].

Long-Term (12-Month) Safety Trial in Adults and Adolescents 12 Years of Age and Older

In the 12-month open-label, active-controlled clinical trial, 404 Asian patients (240 males and 164 females) with perennial allergic rhinitis or vasomotor rhinitis were treated with DYMISTA, 1 spray per nostril twice daily.

In the 12-month, open-label, active-controlled, long-term safety trial in adults and adolescents 12 years of age and older, 404 patients with perennial allergic rhinitis or vasomotor rhinitis were treated with DYMISTA 1 spray per nostril twice daily and 207 patients were treated with fluticasone propionate nasal spray, 2 sprays per nostril once daily. Overall, adverse reactions were 47% in the DYMISTA treatment group and 44% in the fluticasone propionate nasal spray group. The most frequently reported adverse reactions ( ≥ 2%) with DYMISTA were headache, pyrexia, cough, nasal congestion, rhinitis, dysgeusia, viral infection, upper respiratory tract infection, pharyngitis, pain, diarrhea, and epistaxis. In the DYMISTA treatment group, 7 patients (2%) had mild epistaxis and 1 patient ( < 1%) had moderate epistaxis. In the fluticasone propionate nasal spray treatment group 1 patient ( < 1%) had mild epistaxis. No patients had reports of severe epistaxis. Focused nasal examinations were performed and no nasal ulcerations or septal perforations were observed. Eleven of 404 patients (3%) treated with DYMISTA and 6 of 207 patients (3%) treated with fluticasone propionate nasal spray discontinued from the trial due to adverse events.

Long-Term (3-Month) Safety Trial in Pediatric Patients 6-11 Years of Age

In the 3-month open label active-controlled clinical trial, 264 patients (60% male, 40% female) (80% white, 19% black, 4% Asian and 2% other) with allergic rhinitis were treated with DYMISTA, 1 spray per nostril twice daily.

In the 3-month, open label, active-controlled, safety trial in pediatric patients 6-11 years of age 264 patients (128 patients ≥ 6 to < 9 years of age, and 136 patients ≥ 9 to < 12 years of age) with allergic rhinitis (based on the Investigator's assessment) were treated with DYMISTA, 1 spray per nostril twice daily and 89 patients (44 patients ≥ 6 to < 9 years of age, and 45 patients ≥ 9 to < 12 years of age) were treated with fluticasone propionate nasal spray, 1 spray per nostril twice daily. Overall, adverse reactions were 40% in the DYMISTA treatment group and 36% in the fluticasone propionate nasal spray group. The most frequently reported adverse reactions ( ≥ 2%) with DYMISTA were epistaxis, headache, oropharyngeal pain, vomiting, upper abdominal pain, cough, pyrexia, otitis media, upper respiratory tract infection, diarrhea, nausea, otitis externa, and urticaria. In the DYMISTA treatment group 23 patients (9%) had mild epistaxis and 3 patients (1%) had moderate epistaxis. In the fluticasone propionate nasal spray treatment group 8 patients (9%) had mild epistaxis. No patients had reports of severe epistaxis. Focused nasal examinations were performed and no ulcerations or septal perforations were observed. Four of 264 patients (2%) treated with DYMISTA and 3 of 89 (3%) treated with fluticasone propionate nasal spray discontinued from the trial due to adverse events. There were two reports of somnolence, one severe, among children taking DYMISTA [see WARNINGS AND PRECAUTIONS].

Postmarketing Experience
