A member asked:

Hosp. just changed colonoscopy for thursday from 1:00p to 8:30a. do i need to adjust the time to begin drinking the colyte (polyethylene glycol)?

A doctor has provided 1 answer

It takes 12-24 hours: Cleaning colon can take up from 12-24 hours. Just start your prep by 3-4 hours sooner if possible. Do not eat or drink anything for 4 hours before the procedure.
