Summary
Sorbitol given with sodium polystyrene sulfonate has been linked to intestinal necrosis, particularly in the colon, which can be fatal. The risk is greatest in postoperative, renal-impaired or constipated patients.
What this interaction means in plain words
Sodium polystyrene sulfonate and Sorbitol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Sodium polystyrene sulfonate belongs to Miscellaneous; Sorbitol belongs to Gastrointestinal Tract.
Why it happens
The mechanism is not established; hyperosmolar sorbitol effects on the bowel wall combined with resin are suspected.
What to do
Avoid giving sorbitol with the resin, and use premixed sorbitol-containing products with caution. Use alternative potassium binders where appropriate and watch for abdominal pain, distension or GI bleeding.
