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 depression. Patients previously treated for prolonged periods with systemic corticosteroids and transferred to topical corticoids should be carefully monitored for acute adrenal insufficiency in response to stress. In those patients who have asthma or other clinical conditions requiring long-term systemic corticosteroid treatment, too rapid a decrease in systemic corticosteroids may cause a severe exacerbation of their symptoms.
Children who are on immunosuppressant drugs are more susceptible to infections than healthy children. Chickenpox and measles, for example, can have a more serious or even fatal course in children on immunosuppressant doses of corticosteroids. In such children, or in adults who have not had these diseases, particular care should be taken to avoid exposure. If exposed, therapy with varicella-zoster immune globulin (VZIG) or pooled intravenous immunoglobulin (IVIG), as appropriate, may be indicated. If chickenpox develops, treatment with antiviral agents may be considered.
The use of Nasacort Nasal Inhaler with alternate-day systemic prednisone could increase the likelihood of hypothalamic-pituitary-adrenal (HPA) suppression compared to a therapeutic dose of either one alone. Therefore, Nasacort Nasal Inhaler should be used with caution in patients already receiving alternate-day prednisone treatment for any disease.

A decrease in symptoms may occur as soon as 12 hours after starting steroid therapy and generally can be expected to occur within a few days of initiating therapy in allergic rhinitis.
If improvement is not evident after 2 to 3 weeks, the patient should be re-evaluated. (See INDIVIDUALIZATION OF DOSAGE section).
Adults and Children 12 years of age and olderThe recommended starting dose of Nasacort Nasal Inhaler is 220 mcg per day given as two sprays (55 mcg/spray) in each nostril once a day. If needed, the dose may be increased to 440 mcg per day (55 mcg/spray) either as once-a-day dosage or divided up to four times a day, i.e., twice a day (two sprays/nostril), or four times a day (one spray/nostril). After the desired effect is obtained, some patients may be maintained on a dose of as little as one spray (55 mcg) in each nostril once a day (total daily dose 110 mcg per day).
Children 6 through 11 years of ageThe recommended starting dose of Nasacort Nasal Inhaler is 220 mcg per day given as two sprays (55 mcg/spray) in each nostril once a day. Once the maximal effect has been achieved, it is always desirable to titrate the patient to the minimum effective dose.
Nasacort Nasal Inhaler is not recommended for children below 6 years of age since adequate numbers of patients have not been studied in this age group.
