2 day bowel prep for colonoscopy

 

The 2 day bowel prep is often recommended for patients with prior inadequate bowel prep for colonoscopy. There are many reasons for having an inadequate bowel prep. If a 2 day bowel prep is recommended, a large volume bowel cleansing agent like Golytely, Nulytely, Trilyte or Colyte is used in addition to an over the counter laxative like bisacodyl or magnesium citrate. A split-dose regimen is recommended for 2 day bowel prep.
