This medication contains aspartame, an artificial sweetener, which is restricted for patients with phenylketonuria, a hereditary condition. The intake of aspartame should be controlled below the WHO recommended amount, with a maximum of 2.4 g per day for adults. Patients who have hypersensitivity to this medication or genetic issues such as lactose intolerance, lactase deficiency, or glucose-galactose malabsorption should not take this drug. Various adverse reactions have been reported in asthma and allergic rhinitis patients, including headache, fever, cough, abdominal pain, diarrhea, and rashes, so consultation with a doctor is necessary if symptoms occur. In particular, this medication is not used for acute asthma attacks; therefore, appropriate emergency medication must be available in case of acute symptoms. Abruptly discontinuing inhaled corticosteroid preparations or substituting them with this medication can be risky, so medical advice should always be followed. If asthma symptoms worsen due to exercise, this medication should not be used alone, and inhaled beta-agonists should continue to be used. Patients with hypersensitivity to aspirin or non-steroidal anti-inflammatory drugs should avoid using those medications while taking this drug. Serious side effects such as eosinophilia or vasculitis can occur rarely while taking this medication, so any worsening symptoms or unusual symptoms should be reported to healthcare professionals immediately. Interactions with other drugs are not significant, but caution is needed when used in conjunction with specific liver enzyme inducers, and consultation with a doctor is recommended before taking. During pregnancy or nursing, this medication should only be used when clearly needed, and caution is necessary regarding its effects on the fetus or neonate. Children and the elderly can use this medication, but the safety and efficacy based on age should be followed according to a doctor's advice. In case of overdose, no specific antidote is available, so general treatment and monitoring are necessary, and immediate medical attention should be sought if symptoms are severe. This medicine is sensitive to light, so do not open the packaging until right before taking it, and take it quickly after opening. Store in a place out of reach of children, and avoid transferring it to another container, as this can affect quality. During treatment, it is essential to take it consistently every day as prescribed, and if symptoms worsen or unusual symptoms occur, consult a doctor immediately.
