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.
