Tylenol or Acetaminophen is safe to take prior to the procedure.

Drink an 8 oz glass of the solution every 15 minutes until you finish the mixture. It may take 1-2 hours before you begin to have diarrhea. If you develop cramping, bloating or nausea while drinking the preparation, you should stop drinking for about a half an hour. Then you can resume drinking the solution. The diarrhea will usually continue for several hours after completing the bowel preparation.
