MoviPrep® (polyethylene glycol electrolyte solution) is a prescription laxative taken to clean out the bowels before a colonoscopy. This medication comes in the form of a powder, and there is only one standard dosage. Each MoviPrep kit contains four pouches -- two of pouch A and two of pouch B, as well as a disposable container for mixing.
To prepare the solution, empty one pouch A of MoviPrep powder and one pouch B into the mixing container. Add lukewarm water to the top line (one-liter line) and mix to dissolve the powder. After the first container is consumed, a second container will be prepared in the same manner.
MoviPrep is taken either the night before a colonoscopy or split up between the night before and the morning of the procedure. Your healthcare provider will tell you which dosing schedule to follow.
