Discontinue therapy if localized fungal infection of the nose or pharynx develops. Patients w/ active or quiescent tuberculous infections of the resp tract, or untreated fungal, bacterial, or systemic viral infections; patients transferred from long-term administration of systemically active corticosteroids to nasal spray susp. Patients using mometasone furoate over several mth or longer should be examined periodically for possible changes in nasal mucosa. During transfer from systemic corticosteroids, some patients may experience symptoms of w/drawal from systemically active corticosteroids (eg, joint &/or muscular pain, lassitude, & depression initially) despite relief from nasal symptoms & may also unmask pre-existing allergic conditions, eg, allergic conjunctivitis & eczema, previously suppressed by systemic corticosteroid therapy. Safety & efficacy has not been studied for use in the treatment of unilateral polyps, polyps associated w/ cystic fibrosis or polyps that completely obstruct the nasal cavities. Risk of exposure to certain infections (eg, chickenpox, measles) in patients receiving corticosteroids who are potentially immunosuppressed. Very rare reports of nasal septum perforation or increased IOP following use of intranasal corticosteroids. May result in clinically significant adrenal suppression if treated w/ higher than recommended doses. Pregnancy & lactation. Infants born of mothers who received corticosteroids during pregnancy should be observed carefully for hypoadrenalism. Regularly monitor height of childn receiving prolonged treatment w/ nasal corticosteroids at licensed doses as growth retardation may occur.
