There are no data from patients available on the effects of acute or chronic overdosage with intranasal fluticasone propionate. In healthy volunteers, intranasal administration of 2 mg fluticasone propionate twice daily for seven days had no effect on hypothalamic-pituitaryadrenal (HPA) axis function.
Administration of doses higher than those recommended over a long period of time may lead to temporary suppression of adrenal function.
In these patients, treatment with fluticasone propionate should be continued at a dose sufficient to control symptoms; adrenal function will recover in a few days and can be monitored by measuring plasma cortisol.
