This medication should not be used in patients with hypersensitivity to this drug or its components or a history of such reactions. It is also contraindicated in patients with untreated local infections of the nasal mucosa. If a patient has recently undergone nasal surgery or has lesions, ulcers, or trauma in the nasal area, this medication should not be used until the wounds are completely healed. Safety has not been established in infants under 2 years of age. Patients with respiratory tuberculosis, systemic infections, or herpes simplex in the eyes must use this medication cautiously. Patients prone to frequent nosebleeds should be cautious as bleeding may worsen. Patients at risk of varicella or measles infection should take precautions and seek medical attention if necessary. Its effects have not been adequately studied in patients with unilateral nasal polyps or cystic fibrosis, thus it should be used cautiously. Women who are pregnant or may become pregnant, as well as nursing mothers, should use this medication with caution according to a doctor’s advice. Side effects such as headache, nosebleeds, pharyngitis, cough, upper respiratory infections may occur during use. Occasionally, adverse reactions such as skin rashes, nasal mucosal irritation, liver function abnormalities, and blood count changes may occur, so consult a doctor if there are abnormal symptoms. Rarely, immediate allergic reactions such as bronchospasm or difficulty breathing can occur following nasal administration, so discontinue use immediately and seek treatment if symptoms appear. Prolonged use of high doses may lead to systemic corticosteroid side effects, so monitoring is necessary. If symptoms of nasal infections or nasal mucosal irritations persist, discontinue use and seek appropriate treatment. During long-term use, the condition of the nasal mucosa should be regularly checked for abnormalities, particularly if local fungal infections occur in the nose or pharynx, the use of this medication should be stopped and treated. This drug has a low potential to induce glaucoma or cataracts, but if there are changes in vision, an ophthalmologist should be consulted. No special treatment is needed for overdose, but like systemic corticosteroids, adrenal suppression may occur, so caution is necessary. Before use, shake the container well and perform a test spray to ensure an even spray, and avoid spraying directly into the eyes or septum; it should only be used for nasal administration. Keep out of reach of children, and pregnant or nursing women should use it with caution according to a doctor’s instructions. This medication may interact with other drugs, and especially when used in combination with CYP3A4 inhibitors, the risk of side effects may increase, thus caution is necessary.
