Precautions

This medication may rarely provoke generalized tonic-clonic seizures even in patients without a seizure history; therefore, it should be used with caution in patients with electrolyte abnormalities or those taking medications that pose a high risk of electrolyte imbalance. Do not use in patients with bowel obstruction, gastrointestinal obstruction, perforation, toxic colitis, or toxic megacolon, and administer with caution in patients with severe ulcerative colitis. The artificial sweetener aspartame included in this medication is broken down into phenylalanine, hence it should not be administered to patients with phenylketonuria. Do not administer to patients with hypersensitivity, gastrointestinal obstruction, perforation, dehydration, severe heart failure, active malignancy, gastroparesis, glucose-6-phosphate dehydrogenase deficiency, comatose patients, and children under 18 years of age. Administer with caution to patients with intestinal stenosis, severe constipation, the elderly, weakened individuals, those with vomiting reflex disorders, severe renal impairment, acute inflammatory diseases, or dysphagia. Using this medication may cause various adverse reactions, including hunger, hypophosphatemia, hypokalemia, sleep disturbances, dizziness, headache, abdominal pain, nausea, abdominal distension, anal discomfort, fatigue, thirst, tremors, liver function abnormalities, and others. Particularly in the elderly, serious side effects such as bleeding due to gastric mucosal damage, esophageal perforation, heart arrest, and acute pulmonary edema have been reported, requiring careful attention. Before administering this medication, check the patient’s bowel status, and monitor for appropriate bowel movements during administration. If severe abdominal bloating or pain occurs, adjustment of the administration speed or discontinuation may be required. If symptoms of fluid and electrolyte imbalance appear, blood tests should confirm the status and appropriate treatment should be received. Patients with heart disease or a risk of electrolyte imbalance should undergo ECG and electrolyte tests before and after administration. This medication can induce diarrhea, so adequate fluid intake is necessary. Co-administration with stimulant laxatives may increase the risk of mucosal ulcer and ischemic colitis, so it should be avoided. It is advisable to complete eating at least 1 hour before administration and to avoid solid food intake; the effect on driving or operating machinery is not known. This medication may affect the absorption of other drugs, so the potential for absorption inhibition of medications taken within 1 hour prior to administration should be considered. Women who are pregnant or breastfeeding should only be administered this medication when clearly necessary, as its safety has not been established. The safety and efficacy in children have not been confirmed, so it should not be used in pediatric patients. Elderly patients may be more sensitive to the medication, so caution should be exercised in their use. Overdosage may lead to serious side effects such as dehydration, electrolyte imbalance, and reduced blood volume, requiring immediate medical observation and treatment in case of overdose. This medication should not be mixed with other components or flavorings, and it should be taken immediately after dissolving in water; any solution not used within 24 hours should be discarded. Keep out of reach of children; the prepared solution should be stored in a covered container in the refrigerator and not transferred to another container.
