Summary
Insulin shifts potassium into cells, and bowel preparations can cause fluid and electrolyte losses. Together they may contribute to hypokalemia, and fasting during bowel preparation also alters insulin needs. The potassium chloride in the preparation partly offsets this.
What this interaction means in plain words
Insulin aspart and Sodium sulfate / potassium chloride / magnesium sulfate / polyethylene glycol have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Insulin-driven cellular potassium uptake combined with gastrointestinal electrolyte losses from the bowel preparation.
What to do
Adjust the insulin dose for the reduced intake during bowel preparation and check glucose frequently. Check serum potassium in patients with other risk factors for hypokalemia.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
