The laxative TriLyte® (polyethylene glycol electrolyte solution) comes in the form of a powder that is mixed with water to form a solution. To prepare the solution, fill the container TriLyte came in to the indicated line (four-liter mark) with lukewarm water. Shake the container well to dissolve the powder. Normally, eight ounces of the mixed solution are consumed every 10 minutes until four liters are consumed or until bowel movements are watery and clear (which usually requires at least three liters).
