From the Guidelines

She should not take Restoralax (senna) without consulting a healthcare provider first, as the most recent and highest quality study recommends it as an attractive first-line option for individuals with chronic idiopathic constipation, but with limitations and potential adverse events 1. The study published in Gastroenterology in 2023 suggests that senna is an effective option for preventing constipation, but it also highlights the lack of long-term safety studies and potential adverse events such as abdominal pain, cramping, or diarrhea with higher doses 1. Before taking any laxative, it is essential to try lifestyle measures, including:

  • Drinking plenty of water (6-8 glasses daily)
  • Increasing dietary fiber (25-30g daily from fruits, vegetables, and whole grains)
  • Regular physical activity
  • Establishing a consistent bathroom routine If these measures are not sufficient, a healthcare provider might recommend an osmotic laxative like polyethylene glycol (Restoralax), typically starting at 17g (one capful) dissolved in water once daily, or a stimulant laxative like senna, with careful consideration of the potential benefits and risks 1. It is crucial to consult a healthcare provider to determine the most appropriate option based on individual health situation, medication interactions, and the cause of constipation.

From the Research

Treatment Options for Constipation

The use of Restoralax (senna) to prevent constipation is a common approach, but it is essential to consider the available evidence and guidelines for managing constipation.

  • According to a study published in 2020 3, the management of constipation should begin with dietary fiber supplementation and stimulant and/or osmotic laxatives, as appropriate.
  • Another study from 2004 4 suggests that popular therapeutic options for initial treatment of chronic constipation are dietary fiber and medicinal bulk, and subsequent treatments could include saline osmotic laxatives, lactulose, or stimulants like senna or bisacodyl.
  • A more recent study from 2022 5 provides evidence-based recommendations for over-the-counter (OTC) management of chronic constipation, supporting the use of polyethylene glycol-based preparations and senna as first-line laxatives, with good (grade A) evidence.

Efficacy and Safety of Senna

The efficacy and safety of senna as a treatment option for constipation have been studied in various clinical trials.

  • The 2022 study 5 found that senna is supported by good (grade A) evidence as a first-line laxative for the management of chronic constipation.
  • However, it is crucial to note that the use of senna should be guided by individual patient needs and responses to treatment, as well as consideration of potential side effects and interactions with other medications.

Alternative Approaches

In addition to the use of senna, other approaches to managing constipation include dietary changes, lifestyle modifications, and alternative therapies.

  • A study from 2004 6 discusses the potential for new and emerging treatment options for chronic constipation, including prokinetic agents, biofeedback training, and surgery.
  • The 2020 study 3 emphasizes the importance of meticulous analyses of patient history and physical examination, as well as individualized treatment guidance, in managing constipation effectively.
