Polyethylene glycol electrolyte solution is a laxative solution that increases the amount of water in the intestinal tract to stimulate bowel movements. This medication also contains potassium, sodium, and other minerals to replace electrolytes that are passed from the body in the stool.

Polyethylene glycol electrolyte solution is used to clean the bowel before colonoscopy, a barium x-ray, or other intestinal procedures.

Polyethylene glycol electrolyte solution may also be used for purposes other than those listed in this medication guide.

What are the possible side effects of polyethylene glycol electrolyte solution?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor if you have any of these serious side effects:

  • severe stomach pain or bloating;
  • no bowel movement within 2 hours after use; or
  • gagging, choking, or vomiting.

If you have any of these side effects, you may need to drink the medication more slowly, or stop using it for a short time.

  • mild stomach cramps, gas, or bloating;
  • rectal pain or irritation;
  • nausea; or

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.
