A similar list of side effects also occurred in patients suffering from nasal polyps. In rare case studies side effects like nasal ulcers and nasal and oral candidiasis are seen. This was accompanied by nasal burning and irritation, anaphylaxis and angioedema and very rarely nasal septal perforation. Disturbance of taste and smell can also be experienced. Mometasone is a corticosteroid. It may sometimes cause acute adrenal insufficiency in patients that are initially subjected to systemic corticosteroids. When doses of intranasal corticosteroids cross the normal or if the patient has had a very recent steroid therapy, symptoms of hypercorticism occurs that may include rare cases of menstrual irregularities, acneiform lesions and cushingoid features. People who are under medication of drugs that suppress the immune system are susceptible to these side effects. Especially in patients who have not had instances of chickenpox and measles thus not immune to these diseases can have more serious effects of administration of NASONEX.

Nasal corticosteroids should be used under strict professional guidance. Patients with active or quiescent tuberculous infection of the respiratory tract or in untreated fungal, bacterial, systemic viral infections or ocular herpes simplex are strongly recommended gaining a doctor’s advice before the use of this nasal spray. Patients who have gone through cases of recent nasal septum ulcers, nasal surgery or nasal trauma should wait until they are completely cured before use of NASONEX.
