What is GoLYTELY?

GoLYTELY is a laxative solution that helps to stimulate bowel movements. It also includes minerals to replace electrolytes lost in the stool.

GoLYTELY is used to prepare the bowel for a colonoscopy, a barium x-ray, or other intestinal procedures.

GoLYTELY may also be used for reasons not mentioned in this medication guide.

How should I take GoLYTELY?

Follow all instructions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Polyethylene glycol electrolyte powder must be mixed with water to create a solution before using it. Do not add any flavorings such as sugar, honey, artificial sweetener, fruit juices, or other beverages.

Shake the mixture well just before you measure a dose. Drink GoLYTELY exactly as prescribed by your doctor, at the specific portions and time intervals.

This medicine comes with instructions about when and what to eat or drink on your first day of treatment. Each brand may have different instructions.

Do not drink GoLYTELY if it has been less than 1 hour since you last ate solid food. For best results, take the medicine 2 to 4 hours after your last meal.

The first watery stool should appear within 1 hour after you start drinking GoLYTELY. Keep taking the medicine until you have finished all doses prescribed by your doctor.

Drink plenty of clear liquids (water, broth, black coffee, tea, clear soda) before, during, and after taking this medicine. Avoid foods and beverages that contain pulp or are red or purple in color. You may also eat popsicles (not fruit bars or fudge bars) or gelatin without fruit pieces or toppings.

Do not eat or drink anything within 2 hours before your colonoscopy or other medical test.

Store the unmixed powder at room temperature, away from moisture and heat.

Store the mixed solution in a refrigerator, standing upright.

Throw away any GoLYTELY you have not used within 24 to 48 hours after it was mixed (follow directions for your specific brand of this medicine).

What happens if I miss a dose?

Talk to your doctor if you cannot drink all of the solution prescribed for you. Your test or procedure may need to be rescheduled if your bowel is not completely cleansed.

What happens if I overdose?
