From the Guidelines
Bisacodyl should only be used for short-term periods, with a maximum daily dose of 10 mg orally, due to the risks of dependence, electrolyte imbalances, and unknown long-term safety and efficacy 1. When considering the use of bisacodyl, it's essential to weigh the potential benefits against the risks, particularly for prolonged use. The American Gastroenterological Association-American College of Gastroenterology clinical practice guideline recommends bisacodyl for short-term use or rescue therapy, highlighting the importance of cautious use to avoid adverse effects 1. Key points to consider when using bisacodyl include:
- The recommended initial dose is 5 mg daily, with a maximum dose of 10 mg orally daily 1
- Prolonged or excessive use can cause diarrhea and electrolyte imbalance, with unknown long-term safety and efficacy 1
- Bisacodyl is a stimulant laxative, which can lead to dependence and decreased bowel function over time
- Alternative treatments, such as lifestyle changes (increasing fiber intake, staying hydrated, and regular physical activity) or other medications (like fiber, polyethylene glycol, or magnesium oxide), may be safer and more effective for long-term management of constipation 1 In clinical practice, it's crucial to prioritize the patient's overall health and well-being, considering the potential risks and benefits of bisacodyl use. If constipation persists, consulting a healthcare provider to determine the underlying cause and develop an appropriate treatment plan is essential.

From the Research
Duration of Bisacodyl Treatment
- The duration for which Bisacodyl can be taken is generally recommended for short-term treatment of constipation 2.
- Studies have shown that stimulant laxatives, including Bisacodyl, are associated with harmful long-term colonic effects and possible carcinogenic risk, and evidence supports that these agents are used for longer periods than recommended 2.
- Clinical trial evidence describing the effectiveness and safety of long-term treatment (>14 continuous days) with stimulant laxatives, including Bisacodyl, is limited, with most studies having intervention periods of four weeks duration 2.
- The evidence base does not support the use of stimulant laxatives, including Bisacodyl, for more than four weeks 2.
Safety and Efficacy
- Bisacodyl has been shown to be effective in treating constipation, with a positive global assessment of efficacy obtained in 78-99% of patients treated with Bisacodyl or sodium picosulfate 2.
- However, adverse events (AEs) were generally mild but frequent (up to 72%), mostly diarrhea and abdominal pain 2.
- A recent network meta-analysis concluded that Bisacodyl showed similar efficacy to other laxatives for the primary endpoint of ≥3 complete spontaneous bowel movements (CSBM)/week and an increase of ≥1 CSBM/week over baseline 3.
Clinical Guidance
- Bisacodyl is considered a stimulant laxative and has a dual prokinetic and secretory action, acting locally in the large bowel to enhance motility, reduce transit time, and increase the water content of the stool 3.
- The available literature on Bisacodyl provides an overview of its historic background, structure, function, and mechanism of action, as well as important features and studies to guide its use in clinical practice 3.
- Other treatment options for chronic constipation include dietary fiber, medicinal bulk, saline osmotic laxatives, lactulose, and polyethylene glycol laxative, which have been shown to be safe and effective 4.
