This medication contains the artificial sweetener aspartame, which is broken down into phenylalanine in the body. Therefore, patients with the genetic disorder phenylketonuria should not take this medication. Care should be taken not to exceed the daily allowable amount of aspartame, and adults should adhere to the maximum daily dosage. Patients who have had allergic reactions to this medication or its ingredients should not take it, and patients with lactose intolerance or specific genetic issues should also avoid it. Severe allergic reactions like shock or anaphylaxis may occur while taking this medication, thus, if symptoms like low blood pressure, altered consciousness, difficulty breathing, or rashes appear, the medication should be stopped immediately and medical personnel should be notified. Blood-related issues may cause a decrease in white blood cells or platelets, so if symptoms like fever, sore throat, or bleeding occur, the medication should be discontinued. Liver dysfunction may occur, so if jaundice or elevated liver enzyme symptoms appear, careful observation is needed, and discontinuation may be necessary. Respiratory-related side effects such as interstitial pneumonia or eosinophilic pneumonia may occur, thus if symptoms like fever, cough, or difficulty breathing appear, it is crucial to stop taking the medication and receive appropriate treatment. Symptoms related to muscle pain, weakness, or muscle damage may occur, so if these symptoms arise, it is advised to cease taking the medication and consult medical staff. Hypersensitivity reactions such as skin rash, hives, and itching may occur, so if any unusual symptoms are present, discontinue the medication and seek treatment. This medication may affect the mental nervous system, leading to insomnia, anxiety, headache, and drowsiness, hence symptoms should be monitored. Gastrointestinal symptoms such as heartburn, nausea, vomiting, or diarrhea may occur; if symptoms are severe, consultation with medical staff is advisable. Cardiac-related side effects like arrhythmias or palpitations may occur, so caution is needed. Urinary symptoms like dysuria or hematuria may occur; report any unusual symptoms promptly. Long-term use of this medication may lead to unexpected adverse reactions, so regular check-ups are advisable. This medication is not an immediate relief medication for asthma attacks, so this point should be adequately explained to patients. In severe asthma attacks, bronchodilators or corticosteroids should be used, and it should not be relied upon solely to control symptoms. Patients on long-term steroid treatment need to gradually reduce the steroid dose while using this medication, under specialist supervision. Abruptly stopping this medication may cause the original condition to worsen, so caution is warranted. Rarely, serious side effects such as vasculitis may occur when using leukotriene antagonists, hence eosinophil counts or vasculitis symptoms should be carefully monitored. Psychological symptoms, including depression or suicidal thoughts, may appear after taking this medication, thus patient status should be closely observed. If no effects are observed, take care not to use this medication for prolonged periods. Children may have difficulty articulating their symptoms precisely, so guardians should closely monitor the child's condition and immediately inform medical staff of any abnormalities. This medication is metabolized in the liver by a specific enzyme (CYP3A4), so if taken with other drugs that affect this enzyme, blood concentration may change. Particular caution is needed when taking this medication with drugs that inhibit CYP3A4 as it may increase the concentration of this medication. The safety of this medication has not been established during pregnancy, thus women who are pregnant or may become pregnant should consult a physician before use. Safety has not been confirmed for infants under 1 year old or low birth weight newborns, hence it is preferable not to use it in this age group. Elderly patients may have reduced physical function, necessitating careful dosage adjustments and monitoring.
