From the Research
For colonoscopy preparation, Colace (docusate sodium) is not typically recommended as a primary preparation method, and its use should be avoided due to lack of evidence supporting its efficacy in bowel cleansing 1. Instead, the standard colonoscopy preparation usually involves stronger laxatives such as polyethylene glycol solutions (GoLYTELY, MoviPrep), sodium phosphate solutions, or magnesium citrate. These medications more effectively clear the colon of solid matter to allow proper visualization during the procedure. Colace is a stool softener that works by increasing water absorption in the stool, making it easier to pass, but it doesn't have the powerful cleansing effect needed for colonoscopy preparation. Some key points to consider when preparing for a colonoscopy include:
- Following specific preparation instructions provided by your gastroenterologist
- Dietary restrictions, such as clear liquids the day before
- Use of stronger laxatives
- Adequate hydration Using only Colace would likely result in inadequate bowel cleansing and could lead to a poor-quality examination or the need to reschedule the procedure. Recent studies have shown that docusate is not effective in managing constipation, and its use should be reassessed in the older adult population 1. In addition, studies have compared the efficacy of docusate with other laxatives, such as sennosides, and found that docusate is less effective in inducing laxation 2, 3. Therefore, it is recommended to follow the standard colonoscopy preparation guidelines and avoid using Colace as a primary preparation method.
