Can Sodium Picosulphate Syrup Be Given to Diabetic Patients?

Yes, sodium picosulphate can be safely given to diabetic patients for the treatment of constipation, either short-term or as rescue therapy, with no specific contraindications related to diabetes itself. 1

Evidence-Based Recommendation

The American Gastroenterological Association and American College of Gastroenterology specifically recommend the use of sodium picosulphate (SPS) for adults with chronic idiopathic constipation, including those with diabetes, for short-term use (defined as daily use for 4 weeks or less) or as rescue therapy. 1 This recommendation carries a strong recommendation with moderate certainty of evidence. 1

Clinical Efficacy in Diabetic Patients

  • Sodium picosulphate is particularly effective for diabetic patients with constipation. Slow transit constipation, which is typically observed in diabetics due to autonomic nervous system dysfunction, can be best controlled with polyethylene glycol, bisacodyl, or sodium picosulphate. 2

  • Up to 60% of patients with diabetes mellitus suffer from gastrointestinal tract symptoms, including chronic constipation, which correlates positively with patient age, disease duration, and poor glycemic control. 2

  • Treatment of diabetic constipation necessitates long-term intake of laxatives along with proper diabetes control and other general measures such as adequate fluid intake, dietary fiber, and exercise. 2

Safety Profile and Contraindications

The contraindications for sodium picosulphate are NOT related to diabetes but rather to:

  • Congestive heart failure 1
  • Hypermagnesemia 1
  • Severe renal impairment 1
  • Bowel obstruction or ileus 1
  • Allergy/hypersensitivity to ingredients 1

Important Safety Considerations

  • Hyponatremia risk in elderly patients: Sodium picosulphate was associated with a higher risk of hospitalization with hyponatremia in patients 65 years or older (absolute risk increase: 0.05%), though it was not linked with need for urgent CT of the head or death. 1

  • Electrolyte monitoring: In patients with normal baseline renal function, serum magnesium imbalances are transient and of little clinical concern. 1

  • Diabetes-specific considerations: One study examining sodium picosulphate plus magnesium oxide plus citrate found that tolerability, safety, and efficacy were similar for all patients, regardless of the presence of diabetes or renal insufficiency. 1

Practical Implementation

  • Start at a lower dose and increase as tolerated to minimize the most common side effects: abdominal pain, cramping, and diarrhea. 1

  • Use as rescue therapy or in combination with other pharmacological agents for chronic constipation in diabetic patients. 1

  • Ensure adequate hydration: While headache is a commonly reported side effect (38% of patients experience significant headache), there is no evidence that specific fluid regimens prevent this, and patients should be allowed to drink according to thirst. 3

  • No glycemic concerns: Unlike some medications, sodium picosulphate does not affect blood glucose control and requires no adjustment of diabetes medications. 2
