PREPARATION DIAGRAM FOR HALF-LYTELY
PATIENT INSTRUCTIONS – EVENING BEFORE REGIMEN
A.M. the day before the Procedure; add lukewarm drinking water to top of line on bottle. Cap the bottle and shake to dissolve the powder. The mixed solution will be clear and colorless. Use within 48 hours.
5 p.m. (or whenever you get home for the day); take two (2) bisacodyl delayed-release tablets with water (do not chew or crush). Do not take within an hour of taking an antacid such as Tums or Rolaids.
5 p.m., drink one (1) 8-ounce glass of Half-Lytely every 10-minutes until the entire container is gone (about eight (8) glasses). Drink each glass quickly rather than drinking small amounts continuously. This should precipitate bowel movements in approximately one (1) hour. BE SURE TO DRINK ALL OF THE SOLUTION.

The bowels should eventually empty a clear, yellow liquid. You may continue to drink clear liquids up until six (6) hours prior to your procedure and then consume nothing further but approved medications with a sip of water. If by 7 a.m. the bowel movement is still not clear, please call your physician at (847) 247-0187.
