Dosage forms specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension and cardiovascular collapse (AAP 1997; CDC 1982); some data suggests that benzoate displaces bilirubin.
• Enema: For rectal use only; lubricate tip prior to insertion. Discontinue use and notify health care provider if rash around the anus/rectal irritation occurs or if resistance is encountered with insertion; forcing the tube may result in injury or damage to the rectum.
Other warnings/precautions:
• Self-medication (OTC use): When used for self-medication (OTC), patients should be instructed to contact healthcare provider prior to use if nausea, stomach  pain, or vomiting are present, or if a sudden change in bowel habits occurs and persists over 14 days. Patients should discontinue use and notify healthcare provider if rectal bleeding occurs, if a bowel movement fails to occur after use, or if use is needed >7 days.
Monitoring Parameters
Rectal: Periodic rectal exams are recommended in patients with impaired rectal function, especially loss of sensation.
