For Healthcare Professionals
Applies to mometasone nasal: nasal spray
Mometasone is generally well tolerated and, due to the nature of its administration, is not inclined to produce the systemic adverse effects generally associated with the use of corticosteroids. Disturbances of taste and smell have been reported very rarely.
Nervous system side effects have included headache. Headache has been reported to occur 2% more often than reported for patients taking placebo, but has been reported in as many as 36% of treated patients in some studies. Dizziness has rarely been reported.
Local side effects have included nasal irritation, burning, dryness, and soreness in 1% to 6% of patients. Nosebleed has been reported in up to 19% of patients. Pharyngitis has been reported in 3% to 4% of patients. Intranasal mometasone may also cause sneezing. Nasal candidiasis has been reported in at least one patient. Nasal septal perforation has also been rarely reported.
Endocrine side effects have included rare reports of suppression of the hypothalamic-pituitary-adrenal axis. The risk of adrenal suppression is less than that associated with systemic corticosteroids and should only be of concern when using higher than recommended doses.
Gastrointestinal side effects have included rare reports of diarrhea, nausea, vomiting and dyspepsia.
Hypersensitivity side effects have included rare reports of angioedema, pruritus, urticaria, bronchospasm, wheezing, and anaphylaxis.
Immunologic side effects may have included the danger of infections from immune suppression. No conclusive evidence is available to support an increase in tuberculosis or viral infections in patients receiving nasal mometasone. The use of mometasone nasal (the active ingredient contained in Nasonex) in patients with these conditions is not recommended by the manufacturer.
