A 4-week multicenter, double-blind, placebo-controlled, parallel-group trial was carried out with 416 adults with ragweed allergic rhinitis to compare 200 micrograms of fluticasone propionate once daily and 100 micrograms of fluticasone propionate twice daily with placebo. Compared with placebo, both groups receiving fluticasone propionate had greater number of symptom free days (P < .01), lower median symptom scores (P < .01), and greater number of days not requiring rescue medications (P < .001). No significant differences for individual symptoms were found between the two fluticasone propionate groups except that those taking the twice daily dosage used less antihistamine (P < .01) and had greater number of days free of rescue medications (P < .05). Adverse events were comparable between the three groups. These results indicate that topical intranasal fluticasone propionate 200 micrograms once daily and 100 micrograms twice daily are both efficacious and well tolerated.
