Seizure Associated with Hyponatremia Possibly Related to the Use of Polyethylene Glycol and Electrolytes Preparation

Osmotic laxative preparation combining polyethylene glycol (PEG) and electrolytes (sodium and potassium chloride, sodium bicarbonate and sodium sulphate) are frequently used in diagnosis colonoscopy [1,2]. Various preparations of PEG that need to be diluted in water are available. Potential advantage of their use over other preparations is the absence of electrolyte and fluid disturbances, since they do not induce ion or water absorption or secretion compared with other bowel preparations available [1-4]. The present report relates the case of a 53year-old woman presenting with seizures related to severe electrolyte disturbances following the intake of a polyethylene glycol and electrolytes based laxative.
