Review of ketamine safety highlights need for analyses of long‐term effects

Side effects across all categories were more frequently reported with ketamine treatment compared with placebo for depression, a systematic review has found, but few of the studies that were included in the review examined long‐term effects of ketamine dosing. The researchers recommended the initiation of large‐scale trials involving repeated doses of ketamine. Results of the review were published online July 27 in Lancet Psychiatry.
