How to use Colyte solution:

Use Colyte solution as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Your doctor will tell you when to start using Colyte solution. Do not eat any solid foods for at least 2 hours before beginning Colyte solution. It is preferred that you do not eat for 3 to 4 hours before beginning Colyte solution.
  • Drink only clear liquids and do not eat any solid foods from the time you start Colyte solution until your procedure is complete.
  • Colyte solution must be mixed before you use it. Fill the container with the amount of water indicated on the package label. Use lukewarm water to mix Colyte solution to help the medicine dissolve faster. Shake well.
  • Use Colyte solution within 48 hours after you mix it. Keep the mixed medicine in the refrigerator. This may also help improve the taste. Do not add sugar, sweetening agents, or other additives to Colyte solution.
  • Some of these products come with a Flavor Pack. If this product comes with a Flavor Pack and you wish to use it, add the contents of the Flavor Pack into the bottle before you add the water. Do not add any other flavorings. If you do not use the Flavor Pack, throw it away.
  • Shake well before each use.
  • Drink 8 ounces (240 mL) of Colyte solution every 10 minutes until the stool is watery, clear, and free of all solid matter, or until the medicine is gone. At least 3 liters is usually required to produce the watery stool. It is best to drink all of Colyte solution. Be sure to follow the instructions provided by your doctor. It is best to drink each portion quickly rather than sipping it. Rinsing your mouth with mouthwash after each glass of medicine may help get rid of the taste.
  • You will need to drink extra fluids (eg, water, clear soup, fruit juice without pulp, soft drinks, tea and/or coffee without milk) along with Colyte solution. Check with your doctor for instructions.
  • Other medicines taken by mouth within 1 hour of taking Colyte solution may not be absorbed or be effective. Contact your doctor or pharmacist with any concerns you might have about taking your other medicines.
