"As-needed" use was prospectively defined as average use of study medication no more than 75% of study days. Average use of study medications was 57% to 70% of days for all treatment arms. The studies demonstrated significantly greater reduction in TNSS (sum of nasal congestion, rhinorrhea, sneezing, and nasal itching) with FLONASE Nasal Spray 200 mcg compared to placebo. The relative difference in efficacy with as-needed use as compared to regularly administered doses was not studied. Three randomized, double-blind, parallel-group, vehicle placebo-controlled trials were conducted in 1,191 patients to investigate regular use of FLONASE Nasal Spray in patients with perennial nonallergic rhinitis. These trials evaluated the patient-rated TNSS (nasal obstruction, postnasal drip, rhinorrhea) in patients treated for 28 days of double-blind therapy and in 1 of the 3 trials for 6 months of open-label treatment. Two of these trials demonstrated that patients treated with FLONASE Nasal Spray at a dose of 100 mcg twice daily exhibited statistically significant decreases in TNSS compared with patients treated with vehicle. Individualization of Dosage Patients should use FLONASE Nasal Spray at regular intervals for optimal effect. Adult patients may be started on a 200-mcg once-daily regimen (two 50-mcg sprays in each nostril once daily). An alternative 200-mcg/ day dosage regimen can be given as 100 mcg twice daily (one 50-mcg spray in each nostril twice daily). Individual patients will experience a variable time to onset and different degree of symptom relief. In 4 randomized, double-blind, vehicle placebo-controlled, parallel-group allergic rhinitis studies and 2 studies of patients in an outdoor "park" setting (park studies), a decrease in nasal symptoms in treated subjects compared to placebo was shown to occur as soon as 12 hours after treatment with a 200-mcg dose of FLONASE Nasal Spray. Maximum effect may take several days. | ||||
