A female patient previously diagnosed of psychiatric disease used a compound of paracetamol-salicilamide-codeine in suppositories, daily, for more than one year, for migraine. She developed a complete recto-anal stenosis and bowel obstruction requiring permanent colostomy. Ulceration and recto-anal stenosis have been described in association with the use of suppositories, mainly ergotamine. However, this is the first case of total recto-anal stenosis.
