Hypersensitivity to the active substance, mometasone furoate or to any of the excipients.
Mometasone furoate should not be used in the presence of untreated localised infection involving the nasal mucosa, such as herpes simplex.
Because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal surgery or trauma should not use a nasal corticosteroid until healing has occurred.
