Polyethylene glycol-electrolyte solution (PEG-ES) is used to cleanse the colon before procedures such as a colonoscopy or a barium enema. This ensures the doctor has a clear view of the colon walls. PEG-ES belongs to a class of medications known as osmotic laxatives. It induces watery diarrhea to empty the colon. The solution also contains electrolytes to prevent dehydration and other serious side effects associated with fluid loss during the colon-cleansing process.

Uses and Dosage

Follow any special diet instructions provided by your doctor. Typically, you should not eat solid food starting from the day before your procedure until it is completed.

This product must be mixed with water as directed before use. Carefully read and follow all instructions for mixing the product. Once mixed, refrigerate the container, as chilling the liquid improves its taste.

This product may interfere with certain liquid thickeners (starch-based products), potentially increasing the risk of choking. If you use liquid thickeners, consult your pharmacist to choose one that will not interact with this product.

The dosage is based on your medical condition, the procedure, and your response to treatment.

Drink the mixture as directed by your doctor. It is best to drink it quickly rather than sipping slowly. The mixture can also be administered through a nose-to-stomach (nasogastric) tube. Follow your doctor’s specific instructions on when and how much to drink. Be sure to complete the entire amount prescribed by your doctor.

Watery bowel movements usually start within one hour of drinking the mixture. To prevent dehydration, drink plenty of clear liquids as directed by your doctor.

Avoid taking other oral medications within one hour before starting this product, as it may reduce their effectiveness. If you are unsure when to take your other medications, consult your doctor or pharmacist.

What can I eat or drink when I use Colyte Lavage Prep?

You’re probably allowed to eat a light breakfast. You can only drink clear liquids, such as water, fruit juices without pulp, clear broth, coffee, or tea. Don’t eat or drink anything that’s red or purple in color, such as popsicles or soft drinks, because the dye can be mistaken for blood during your procedure. Most likely, you’ll need to stop drinking all liquids 2 hours before your procedure starts.
