PEG (polyethylene glycol) with electrolyte is used to clean out the intestines before certain bowel exam procedures such as colonoscopy or barium enema X-rays. It is a laxative that works by drawing large amounts of water into the colon. This effect results in watery bowel movements. Clearing stool from the intestines helps your doctor to better examine the intestines during your procedure.

Drink one 8-ounce glass (240 milliliters) of the mixture every 10 minutes until your watery stool is clear and has no solid matter.

Ask your doctor or pharmacist if you have any questions about how to mix or take this product or what to expect after taking this product.

If severe bloating or abdominal pain occurs, wait longer (15-30 minutes) between each glass of the mixture, or temporarily stop drinking the mixture until the symptoms improve.

Watery bowel movements usually begin within 1 hour after you start to drink the mixed liquid. You may drink more clear liquids so that you do not lose too much body water (become dehydrated).

Do not take any other medications by mouth within 1 hour of starting to drink the mixed liquid because your body may not absorb the other medications. Ask your doctor or pharmacist if you are not sure when to take your other medications.
