This medicine contains aspartame, an artificial sweetener, which is broken down into phenylalanine in the body. Therefore, patients with phenylketonuria, a genetic disorder that requires restriction of phenylalanine intake, should not take this medication. Additionally, this medication contains lactose and should not be administered to patients with genetic issues such as galactose intolerance, lactose deficiency, or glucose-galactose malabsorption. This drug is used for the treatment of asthma or allergic rhinitis but cannot be used during an acute asthma attack, and separate emergency medications should always be kept on hand for acute symptom relief. Do not abruptly stop or replace inhaled corticosteroids while taking this medication, and dosage should be adjusted gradually according to a physician's instructions. During treatment, unusual reactions such as fatigue, headache, dyspepsia, cough, rash may occur, and if these symptoms arise, one should consult healthcare professionals. Patients taking this medication may experience neuropsychiatric symptoms, such as anxiety, depression, hallucinations, or suicidal thoughts, and should immediately inform a physician if such changes occur. Patients with hypersensitivity to aspirin or non-steroidal anti-inflammatory drugs should avoid using these medicines while taking this medication, and it is unclear whether this medication can treat asthma attacks in aspirin-sensitive asthma patients. If pregnant or breastfeeding, the safety of this medication has not been fully established, so it should be used only as deemed necessary by a physician. This medicine is also available for use in children and the elderly, but particularly in young children, the established age range for safety and efficacy should be followed, and caution is needed as seniors may respond differently to the medication. In the case of overdose, there is no specific antidote, so general treatment based on symptoms should be carried out and managed appropriately according to a physician's instructions. This medication is sensitive to light, so it should be taken immediately after opening, and stored out of reach of children. Finally, this medication should be taken consistently, even when asymptomatic, and dosages of other asthma treatments should not be decreased or discontinued arbitrarily while taking this.
