From the Guidelines
Docusate sodium enema takes 5–20 min to act. This is based on the most recent and highest quality study available, which provides guidance on the management of constipation in advanced cancer patients 1. The study outlines the rationale for use and potential adverse effects of various enemas, including docusate sodium enema.
Key Points to Consider
- The docusate sodium enema works by softening stool, aiding water penetration of the faecal mass, and stimulating the bowel to contract.
- Common adverse effects of docusate sodium enema include anal or rectal burning and pain, as well as short-lasting diarrhea.
- It is essential to weigh the benefits and risks of using docusate sodium enema, particularly in patients with advanced cancer or other underlying medical conditions.
- The study also discusses other types of enemas, such as normal saline, soap solution, osmotic micro-enema, and hypertonic sodium phosphate enema, each with its own rationale for use and potential risks.
- When considering the use of docusate sodium enema, it is crucial to assess the patient's individual needs and medical history to determine the most appropriate treatment option. Some key factors to consider when using docusate sodium enema include:
- The patient's level of constipation and ability to tolerate the enema
- The presence of any underlying medical conditions, such as neutropaenia or thrombocytopaenia, that may contraindicate the use of enemas
- The potential for adverse effects, such as anal or rectal burning and pain, and the need for close monitoring and follow-up care.

From the Research
Time it Takes for Docusate to Act
- The time it takes for docusate to act is not explicitly stated in the provided studies 3, 4, 5, 6, 7.
- However, a study published in 2022 found that 42.8% of patients who received docusate monotherapy experienced treatment failure, defined as not having a bowel movement within 5 days of starting docusate after surgery 6.
- Another study published in 2024 found that 58% of patients receiving oral docusate sodium required rescue medications, suggesting that docusate may not be effective in preventing constipation 7.
Factors Affecting Docusate's Onset of Action
- The effectiveness of docusate may be influenced by various factors, including the dose and duration of treatment, as well as individual patient characteristics such as age and underlying medical conditions 5.
- The use of docusate in combination with other medications, such as opioids, may also impact its onset of action and overall efficacy 4, 6, 7.
Limitations of Current Evidence
- The current evidence on the time it takes for docusate to act is limited by the lack of high-quality studies and inconsistent findings across different studies 3, 4, 5, 6, 7.
- Further research is needed to determine the optimal dose and duration of docusate treatment, as well as its effectiveness in different patient populations 4, 5, 6, 7.
