Side Effects & Adverse Reactions

The replacement of a systemic corticosteroid with a topical corticoid can be accompanied by signs of adrenal insufficiency, and in addition some patients may experience symptoms of withdrawal, e.g., joint and/or muscular pain, lassitude and/or depression. Patients previously treated for prolonged periods with systemic corticosteroids and transferred to flunisolide should be carefully monitored to avoid acute adrenal insufficiency in response to stress.

When transferred to flunisolide, careful attention must be given to patients previously treated for prolonged periods with systemic corticosteroids. This is particularly important in those patients who have associated asthma or other clinical conditions, where too rapid a decrease in systemic corticosteroids may cause a severe exacerbation of their symptoms.

The use of flunisolide with alternate-day prednisone systemic treatment could increase the likelihood of HPA suppression compared to a therapeutic dose of either one alone. Therefore, flunisolide treatment should be used with caution in-patients already on alternate-day prednisone regimens for any disease.

Persons who are on drugs that suppress the immune system are more susceptible to infections than healthy individuals. Chicken pox and measles, for example, can have a more serious or even fatal course in non-immune pediatric patients or adults on corticosteroids. In such pediatric patients or adults who have not had these diseases, particular care should be taken to avoid exposure. How the dose, route and duration of corticosteroid administration affects the risk of developing a disseminated infection is not known. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If a nonimmune patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. (See the respective package insert for complete VZIG and IG prescribing information.) If chickenpox develops, treatment with antiviral agents may be considered.

The size of the droplets produced by the unit is in excess of 8 microns to facilitate deposition on the nasal mucosa. The contents of one nasal spray bottle delivers 200 sprays.

Each mL Contains: ACTIVE: Flunisolide 0.25 mg (0.025%); INACTIVES: Propylene Glycol, Polyethylene Glycol 3350, Butylated Hydroxyanisole, Edetate Disodium, Sodium Citrate, Citric Acid and Purified Water.
