# Psychiatric Adverse Effects From Prucalopride in a Medically Complex Adolescent

## TL;DR

A 15-year-old girl with complex health issues developed hallucinations and suicidal thoughts after taking prucalopride for constipation, highlighting a rare psychiatric side effect.

## Contribution

This is the second documented case of acute neuropsychiatric symptoms linked to prucalopride in adolescents.

## Key findings

- Prucalopride triggered visual and auditory hallucinations in a medically complex adolescent.
- Suicidal ideation occurred shortly after a single dose of prucalopride.
- Psychiatric symptoms resolved after discontinuing the drug and providing targeted interventions.

## Abstract

Background: Prucalopride is a highly selective, 5-HT4 receptor agonist that can be used for the treatment of chronic constipation in individuals for whom laxatives fail to provide adequate relief. The current case study describes adverse neuropsychiatric symptoms following the administration of prucalopride in a 15-year-old female with a complex physical and mental health history to manage chronic constipation.

Case Summary: A single 2 mg dose of prucalopride was prescribed to a 15-year-old female to manage her chronic constipation due to a diagnosis of autoimmune enteric neuropathy. Following the oral administration of prucalopride, the patient started experiencing visual and auditory hallucinations, along with suicidal ideation. Prucalopride was ceased, with the patient receiving psychopharmacology and psychological intervention to address the acute onset psychiatric symptoms.

Practical Implications: To our knowledge, this is the second documented case of acute onset neuropsychiatric symptoms following the administration of prucalopride. Clinicians should be aware of this possible side effect, particularly if considering administering prucalopride in patients with neurodevelopmental and psychiatric comorbid histories. Increased supervision and monitoring is recommended in these patients if prucalopride is administrated.
