How to prepare for your colonoscopy
About This Information
This plan is meant to be a guide, not medical advice.
Please be sure to communicate with your health care provider about any medicines you are taking. This includes vitamins, herbs, supplements, aspirin products, arthritis medications, anticoagulants (blood thinners such as warfarin or heparin), clopidogrel, insulin or iron products. Also share any information about allergies to any medicines including any type of anesthesia.
Most medications can be continued during the prep period, but some can interfere with either the bowel prep or the colonoscopy. Your healthcare provider will provide specific instructions for your medicines and/or allergies. Read them ahead of time! You may need to shop for supplies and laxatives and follow a special liquid diet for at least a day before the test.
