Cautions

• Do not use laxatives when nausea, vomiting, or severe abdominal pain is present
• Caution with renal impairment orascites; increases risk of sodium retention and edema; obtain baseline and postprocedure labs in patients with renal impairment; monitor closely to avoidhyperphosphatemia
• Caution in patients with acolostomy
• Caution in children aged 2-11 years or elderly patients with comorbidities
• Caution with pre-existing electrolyte disturbances or patients taking diuretics or other medications that may alter electrolytes
• Additional liquids by mouth are recommended to prevent dehydration; inadequate fluid intake may result inhypovolemiadue to excessive fluid loss
• Exceeding daily dose, no return of enema solution, retention time over 10 minutes, or failure to have a bowel movement within 30 minutes of enema use may lead to electrolyte disturbances, including hypernatremia, hyperphosphatemia,hypocalcemia, andhypokalemia
• Severe dehydration and electrolyte abnormalities associated with serious complications (eg, acute kidney injury, arrhythmias, and death) have occurred in adults and children who overdosed using oral or rectal over-the-counter (OTC) sodium phosphate solutions to treat constipation
• Use caution in unstableangina,cardiomyopathy, history ofmyocardial infarctionarrhythmia, patients with or at risk for arrhythmias, including prolonged QT interval, cardiomyopathy, recent myocardialinfarction; caution with other QT-prolonging drugs, consider pre-/postdose ECGs and lab tests in high-risk patients
• Correct dehydration prior to using in bowel preparations
• Use caution in patients with gastric retention or hypomotility, severe activeulcerative colitisorileus, severe, chronic constipation
• Use caution in history of seizures, those at high risk of seizures or onseizuretherapy; obtain baseline and postprocedure labs in high-risk patients
