Irritable bowel syndrome - Management
Which antidepressant should I prescribe?

  • Tricyclic antidepressants (TCAs) are the antidepressants of choice in the management of irritable bowel syndrome (IBS).
    • Most studies of TCAs in IBS have used amitriptyline or trimipramine.
    • CKS therefore recommends the use of either of these TCAs in the management of IBS.
    • Neither amitriptyline or trimipramine are licensed for the management of IBS.
  • Selective serotonin reuptake inhibitors (SSRIs) should be considered for people with IBS only if TCAs have been shown to be ineffective.
    • Citalopram, fluoxetine, and paroxetine have been studied in the management of IBS.
    • CKS therefore recommends the use of one of these three SSRIs in the management of IBS.
    • These SSRIs are not licensed for the management of IBS.
