This medication contains the artificial sweetener aspartame, so it should not be used in patients with phenylketonuria, a genetic disorder that requires restriction of phenylalanine intake. This medication contains lactose, so it should not be administered to patients with genetic issues such as galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption. Some patients using this medication, particularly those with asthma and allergic rhinitis, may experience symptoms such as fatigue, headache, abdominal pain, fever, cough, and nasal congestion, so caution is advised. In pediatric patients, cases of pharyngitis, nausea, diarrhea, loss of appetite, ear infections, and viral infections have been reported, and any adverse reactions should be discussed with a physician. This medication is not intended for the treatment of acute asthma attacks; therefore, patients should always carry appropriate emergency medications for sudden symptoms. When reducing the dose of inhaled corticosteroids, it must be done gradually under medical supervision, and it should not be suddenly switched or discontinued. Patients with hypersensitivity to aspirin should avoid taking aspirin or non-steroidal anti-inflammatory drugs while on this medication, as there is no evidence that this medication is effective in treating bronchoconstriction caused by such medications. Rarely, eosinophilia and vasculitis symptoms may occur while taking this medication, so if symptoms such as eosinophilia, skin rash, or worsening of pulmonary symptoms arise, immediate medical evaluation is necessary. Pregnant women should exercise caution when taking this medication, and those who are breastfeeding should also be aware that this medication may be excreted in breast milk. Safety and efficacy for children under 6 months have not been established; therefore, use in this age group is not recommended. This medication is photosensitive, so it should be opened immediately before use, and once prepared, it should be taken as soon as possible, ensuring it is stored out of reach of children. In case of overdose, there is no specific antidote; therefore, general symptomatic treatment should be applied, and medical attention should be sought immediately if adverse symptoms occur. If neuropsychiatric symptoms or behavioral changes occur while taking this medication, it is essential to inform a physician, and doses of other asthma medications should not be reduced or discontinued arbitrarily.
