Treatment of constipation, bowel preparation before colonoscopy or surgery, and symptomatic relief of dry mouth (as an ingredient in certain lozenges).
As an osmotic laxative, sorbitol draws water into the colon through osmosis, which softens stool, increases its volume, and stimulates bowel movements to facilitate evacuation.
May cause abdominal cramping, gas, or diarrhea. Patients with fructose intolerance should avoid oral sorbitol. Use with caution in those with electrolyte imbalances or dehydration. Not recommended for long-term daily use without medical supervision.
