This medication is used for the prevention and treatment of asthma and allergic rhinitis. Abnormal psychiatric symptoms may appear during treatment, so patients or caregivers should consult a doctor immediately if symptoms such as agitation, anxiety, depression, sleep disturbances, hallucinations, or suicidal thoughts occur. The artificial sweetener aspartame contained in this medication is broken down into phenylalanine, so patients with the genetic disorder phenylketonuria should not take this medication. Formulations containing lactose should not be administered to patients with genetic issues such as galactose intolerance, lactase deficiency, or glucose-galactose malabsorption. This medication is not a treatment for acute asthma attacks, and appropriate emergency medications must be on hand in case of emergencies. When reducing the dose of inhaled corticosteroids, this should be done gradually under a doctor's supervision, as sudden changes can be dangerous. It should not be used alone for exercise-induced bronchospasm treatment, and β-agonists for inhalation should continue to be used if necessary. Patients with hypersensitivity to aspirin or non-steroidal anti-inflammatory drugs should not take these medications while on this drug. Rarely, generalized eosinophilia and vasculitis symptoms may occur while taking this medication, so careful observation and consultation with a doctor are necessary upon symptom occurrence. Although no special interactions have been reported when used with other medications, caution is needed when used concurrently with some strong enzyme inducers. It should only be used during pregnancy if absolutely necessary, and caution is required during breastfeeding. Safe use has been established for children and elderly patients, but there is insufficient safety data for children under 6 months of age. In case of overdose, there is no specific antidote, so general symptomatic treatment and clinical monitoring are necessary. This medication should be stored out of reach of children, and it should not be transferred to another container. It should be taken regularly even if there are no symptoms, and immediate consultation with a doctor is necessary if symptoms worsen or unusual symptoms appear.
