Psyllium Fiber Safety and Efficacy in Incomplete Quadriplegia

Key Safety Considerations

The American Gastroenterological Association and American College of Gastroenterology guidelines support psyllium as a safe and effective treatment for chronic constipation in patients with incomplete quadriplegia, with a recommended dose of 5 g twice daily, when taken with adequate fluid intake of 240-300 mL of water per dose 1

The American Gastroenterological Association and American College of Gastroenterology guidelines recommend starting with 5 g of psyllium twice daily, which represents the minimum effective dose, and continuing treatment for at least 4 weeks to achieve optimal benefit 1, 2, 3
Psyllium increases weekly bowel movements by an average of 2.32 movements (95% CI: 0.86-3.79) and improves overall symptom relief with a relative risk of 1.86 (95% CI: 1.49-2.30) 3, 1

Flatulence is the most common side effect, occurring more frequently than with placebo, with a standardized mean difference of 0.80 (95% CI: 0.47-1.13) 1
Abdominal distension may occur, particularly during initial treatment, but these effects are generally mild and do not require discontinuation 1, 2, 3

Emphasize the non-negotiable requirement for adequate fluid intake with each dose to patients, with a minimum of 240-300 mL of water per dose 1
Consider alternative therapies, such as polyethylene glycol or lactulose, if fluid intake cannot be assured 4
