Rapid drinking of each portion is preferred to drinking small amounts continuously. A watery bowel movement should occur in approximately 1 hour after drinking the solution. See package insert for complete information.

Patients with impaired gag reflex and patients prone to regurgitation or aspiration should be observed during the administration of the solution. If a patient experiences severe bloating, distention or abdominal pain, administration of the solution should be slowed or temporarily discontinued until the symptoms abate.
