Lai JB, et al. - Researchers attempted to determine the prevalence of medication-emergent constipation among patients with obsessive-compulsive disorder (OCD). This study comprised of 51 OCD patients. It was reported that the proportion of patients using laxatives was 31.4%, and the commonly used laxatives were phenolphthalein tablet, lactulose and congrongtongbian oral liquid. In contrast with the nonlaxative group, hospital stays were revealed to be longer in the laxative group. A preliminary picture of constipation and laxative use was gained in hospitalized OCD patients. Data suggested close monitoring and treatment of constipation in the case of OCD patients with pharmacotherapy.
