For Healthcare Professionals
Applies to flunisolide nasal: nasal spray
Flunisolide has been generally well tolerated and, due to its route of administration, has not been inclined to produce the adverse effects generally associated with systemic corticosteroids. The most frequent complaints have been related to nasal mucus membrane irritation.[Ref]
Gastrointestinal side effects have included nausea and vomiting in less than 5% of patients. Bitterness and/or bad taste occurred more frequently.[Ref]
Respiratory side effects have included nasal irritation, burning and stinging, congestion, epistaxis, sneezing, and rarely, nasal septal perforations. Temporary or permanent loss of the sense of smell and taste have occurred with both oral inhalation and intranasal formulations.[Ref]
Nervous system side effects have been generally limited to headache, which occurred in less than 5% of patients.[Ref]
Endocrine side effects have rarely included suppression of the hypothalamic-pituitary-adrenal axis. The risk of adrenal suppression has been less than that associated with systemic corticosteroids and was generally only of concern when using higher than recommended dosages or in patients who may be particularly sensitive.[Ref]
Dermatologic side effects have included rare reports of rash.[Ref]
