A comprehensive systematic review and meta-analysis of 13 studies found that MDMA-assisted psychotherapy (MDMA-AP) is associated with increased odds of side effects compared to control conditions. In Phase 2 trials, MDMA-AP roughly doubled the odds of any side effect during medication sessions and in the following week. In Phase 3 trials, the odds of any adverse event during treatment were about 3.5 times higher with MDMA-AP than with placebo-assisted psychotherapy. Most side effects were transient and mild or moderate. However, the evidence had very low to moderate certainty, most trials had high risk of bias, and none adequately followed CONSORT Harms 2022 reporting guidelines, highlighting the need for further safety research.
