This medication contains the artificial sweetener aspartame, and patients with the genetic disorder phenylketonuria should not take it. Aspartame breaks down into phenylalanine in the body, which can be dangerous for those who must limit phenylalanine intake. This medication contains lactose, so patients with genetic issues such as galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption should not take it. Caution is necessary as various adverse reactions such as fatigue, headache, abdominal pain, rash, and cough may occur in asthma or allergic rhinitis patients. Adverse reactions have been reported especially in children and adolescents, so if any abnormal symptoms occur, immediate consultation with a physician is necessary. This medication is not intended for the treatment of acute asthma attacks; therefore, always keep a rescue inhaler available for acute symptoms. Inhaled corticosteroids should not be suddenly discontinued or replaced with this medication without proper medical supervision. Patients allergic to aspirin should avoid taking aspirin or non-steroidal anti-inflammatory drugs while on this medication. Although there have been no significant reports of drug interactions when using this medication with other asthma preventive and treatment medications, monitoring by a physician is required when used in combination with specific drugs. Women who are pregnant or breastfeeding should use this medication with caution and consult a doctor if necessary. For children, safety and efficacy may vary by age, so it is important to follow the appropriate dosage and usage according to their age. In cases of overdose, there is no specific antidote; seek appropriate medical treatment immediately, and general symptomatic treatment is required. This medication is sensitive to light, so it is important to open it just before taking and to take it immediately after preparation. Keep out of reach of children and do not transfer to other containers. This medication should be taken consistently even when asthma symptoms are absent, and if symptoms worsen, consultation with a physician is essential. It is important to inform the doctor immediately if any neuropsychiatric symptoms or adverse reactions occur during use.
