See section 1.6 Laxatives
People with IBS should be advised how to adjust their doses of laxative or antimotility agent according to the clinical response. The dose should be titrated according to stool consistency, with the aim of achieving a soft, well-formed stool (corresponding to Bristol Stool Form Scale type 4).
Antidepressants are not licensed for use in IBS and should only be used if laxatives, loperamide or antispasmodics have not helped.
See section 4.3 Antidepressant drugs
