Summary Safety Review - Atypical antipsychotics - Assessing the Potential Risk of Urinary Retention

Health Canada carried out a safety review to look into the use of atypical antipsychotics and the potential risk of having difficulty urinating or not being able to fully empty the bladder (urinary retention). This can be an emergency that requires medical attention. This review was triggered by new safety information received from the manufacturer of Seroquel (quetiapine) that included reports of urinary retention in patients using quetiapine.
