There is no great bowel prep for a colonoscopy. We have been doing these for 40 years and they haven’t found a better colonoscopy prep. They have tried with fleets preps and tablet preps but these have caused problems with kidney function so are rarely used anymore. What we do know is the cleaner you can get your colon the more thorough of an exam we can give you. Studies have shown if you take the bowl prep split the night before and the morning of it does give a cleaner result. There is no fun way to do a bowel prep but the cleaner you can get your colon the better of an exam we can do for you.
