If such symptoms or behavior changes occur, discontinue this medication immediately and inform a doctor. This medication contains the artificial sweetener aspartame, so patients with phenylketonuria should avoid taking it. Additionally, this medication contains lactose, hence patients with galactose intolerance or lactase deficiency should refrain from use. This medication is not for the treatment of acute asthma attacks, and appropriate emergency medication should be used for acute symptoms. Do not use alone for exercise-induced bronchospasm; continue using inhaled bronchodilators as needed. Patients with an allergy to aspirin should avoid taking aspirin or non-steroidal anti-inflammatory drugs during the use of this medication. This medication can rarely cause serious side effects such as eosinophilia and vasculitis, so doctors should carefully monitor patients. If pregnant or breastfeeding, consult a physician before use and only use if necessary; children and the elderly should also take it according to a physician's instructions. In case of overdose, there is no specific antidote, thus appropriate treatment and monitoring are required based on symptoms.
