A rare case of small bowel obstruction secondary to activated charcoal administration.

Intestinal obstruction is a rare complication of the administration of activated charcoal. We describe a 22-year-old patient who had received multiple-dose activated charcoal for carbamazepine intoxication. The patient presented with sudden-onset abdominal pain after discharge from the emergency room, and abdominal imaging examinations revealed findings consistent with small bowel obstruction.
