Abstract:
Bowel dysfunction, mainly constipation, is a well-known and anticipated side effect of opioids. The physician prescribing an opioid frequently confronts the challenge of preventing and treating bowel dysfunction. Different strategies have emerged for managing opioid-induced constipation. These strategies include physical activity, maintaining adequate fluid intake, adhering to regular daily bowel habits, using laxatives and other anticonstipation medications and, recently, using a peripheral opioid antagonist, either as a separate drug or in the form of an opioid agonistantagonist combination pill. What options exist for the physician when a patient receiving opioids complains of diarrhea, cramps and bloating, rather than the expected constipation? The present article describes a possible cause of opioid-induced diarrhea and strategies for management.
