This medicine contains the artificial sweetener aspartame; therefore, patients with the genetic disorder phenylketonuria should not take it. The daily intake of aspartame should be limited to below the WHO recommended amount, and adults can take a maximum of 2.4 grams per day. Patients who are allergic to this medication or are hypersensitive to any of its components should not use it. Additionally, since it contains lactose, it should not be administered to patients with genetic issues such as galactose intolerance, lactase deficiency, or glucose-galactose malabsorption. This medication is not used as a treatment for acute asthma attacks, and patients should always have separate emergency medication ready in case of asthma exacerbation. While taking this medication, neuropsychiatric symptoms such as anxiety, depression, hallucinations, and suicidal thoughts may occur; immediately consult a doctor if these symptoms arise. Do not use this medication alone for treatment of exercise-induced bronchoconstriction; continue using inhaled beta-agonists and have them ready for emergencies. Patients sensitive to aspirin should not take aspirin or non-steroidal anti-inflammatory drugs while taking this medication; it has not been determined if this drug treats bronchoconstriction in patients with aspirin-sensitive asthma. During the course of this medication, rare side effects such as eosinophilia or vasculitis may occur, so the doctor should closely monitor the patient's symptoms. No specific interactions have been reported when used with other medications, but careful observation is required when used with strong liver enzyme inducers such as phenobarbital, rifampicin, and phenytoin. It should only be administered during pregnancy if the necessity is clear, and caution is needed while breastfeeding. In children, especially infants under 6 months, safety and efficacy have not been established, so use should be avoided. In the case of overdose, there is no specific antidote; general symptomatic treatment and clinical monitoring are required. This medication is sensitive to light, so it should be opened immediately before use and should be taken right after opening while keeping it out of reach of children. Lastly, this medication should be continually taken even when there are no asthma symptoms, and if symptoms worsen or if the use of emergency medication increases compared to usual, immediately consult a doctor.
