Colonoscopy Prep Prep. It’s one of the most dreaded steps of a colonoscopy. It’s also one of the most important. Share on Facebook Share on LinkedIn Share on Twitter Copy this URL Share via Email It's crucial that your gastroenterologist gets a good look inside of your colon to properly screen for colorectal cancer. If you don’t have a thorough prep, your colon may not be clear of stool, which means your doctor can't see the walls of the colon clearly. If this happens, you may need to repeat the procedure, both the prep and the colonoscopy. Don’t let this happen to you! Which Colonoscopy Prep Should I Use? There are several prep brands to choose from, and it can get confusing to know which one to use. Your doctor will recommend what they prefer. The volume of prep that you’ll need to drink depends on the brand, and it ranges from 10 ounces to 128 ounces. It’s worth noting that lower-volume preps need to be supplemented with a similar volume of water as the larger-volume preps. Basically, you’ll be drinking a lot if you use a liquid prep! There are pill formula options as well, which also require large volumes of water to work effectively. The cost of each prep differs. Talk to your doctor and your insurance company to figure out which option works best for you and your budget. Tips to Improve Your Colonoscopy Prep Clear your schedule.
