For at least five days before the colonoscopy examination, do NOT take iron. Speak to your physician for any other medications, especially blood thinners and medicines to control diabetes.
On the day before the exam, you may need to mix a bowel preparatory solution according to the instructions and refrigerate it for use that evening. Have a clear liquid breakfast. Water, tea, coffee (no milk or cream), soda, broth, clear juice, popsicles and JELL-O are examples of clear liquids. Be sure NOT to ingest red liquids. You’ll want to have a clear liquid lunch and dinner this day, too. In the afternoon, you may have to take a laxative as prescribed by your physician.
That evening, you’ll most likely have to begin drinking a preparatory solution in advance of your test. Take this as directed. Drink each glass quickly rather than drinking small amounts continuously. Be sure to drink all of the solution recommended. The solution will cause you to have loose stools, which is the expected result. Even if you have liquid diarrhea, please continue taking it. You may have nausea while drinking the solution, but you should drink all of it to ensure an adequate preparation. You may still have loose bowel movements for about 1 to 2 hours after you have completed drinking all of the solution. Continue clear liquids until bedtime.
Check with your individual physician about how to take your regular medications.
On the morning of the examination, you usually can take your regular medications with clear water, unless otherwise instructed by your doctor. Check with your doctor. It is recommended that you DO NOT DRINK ANYTHING starting 4 hours before your scheduled procedure time or the procedure will need to be cancelled. You should plan to have alternate transportation that is flexible as procedures may run longer than expected.
