Patients who are allergic to this medication or have genetic issues such as lactose intolerance, lactase deficiency, or glucose-galactose malabsorption should not take it. This medication is not for use during acute asthma attacks, so immediate appropriate emergency treatment should be sought if an asthma attack is severe. Asthma patients should always carry a rescue inhaler while taking this medication. When reducing the dose of inhaled corticosteroids, it should be done gradually under a doctor’s guidance, as sudden changes can be dangerous. Neuropsychiatric symptoms, such as anxiety, depression, and hallucinations, may occur during this medication's use, and if such symptoms arise, immediate consultation with a doctor is necessary. Patients with exercise-induced bronchospasm should not use this medication alone, but in conjunction with inhaled beta-agonists. Patients who are hypersensitive to aspirin or non-steroidal anti-inflammatory drugs should avoid taking these medications simultaneously. Serious side effects such as vasculitis or systemic eosinophilia can occasionally appear in asthma patients, so doctors should closely monitor the patient's condition. There have been no reported significant drug interactions when this medication is used in conjunction with other asthma prevention and treatment medications, but caution is required when used with certain enzyme inducers. Pregnant or breastfeeding women should consult a doctor before taking this medication, and it should be used only when necessary. It is advisable not to use this medication in children under 6 months, as safety and efficacy have not been established. There are no specific antidotes for overdose; general symptomatic treatment and medical observation are necessary. This medication is sensitive to light, so it should not be opened until just before use and should be taken immediately after opening. It should be kept in a safe place out of reach of children, and transferring it to another container should be avoided.
