Can mometasone furoate nasal spray be used long-term?

Generally, mometasone furoate nasal spray can be used long-term for chronic nasal conditions under a doctor's guidance, but it should not be used long-term without medical supervision. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed explanations are as follows:

For long-term management of conditions such as allergic rhinitis or chronic sinusitis, prolonged use at the recommended dosage is acceptable after evaluation by a physician. Doctors will regularly review the patient’s condition and adjust the treatment plan according to symptom changes, thus maintaining therapeutic effectiveness while keeping risks at a low level. Most patients tolerate the medication well when used correctly.

However, long-term use without medical advice or擅自 altering the dosage is not recommended. This may lead to nasal mucosal dryness or occasional nosebleeds. Prolonged excessive use could impair normal mucosal function, and in rare cases may even cause systemic adverse effects, which would be counterproductive to the long-term management of nasal diseases.

During treatment, it is essential to strictly follow the doctor’s instructions or the drug’s package insert—do not alter the duration or dosage without authorization. If nasal discomfort worsens or new abnormal symptoms develop, seek medical review promptly so that the doctor can reassess and adjust the treatment plan accordingly.
