abstract="BACKGROUND: Divalproex has become the most prevalent mood stabilizer for bipolar disorder. However, little is known its effects in the prevention of suicide in patients with bipolar disorder, and recent FDA announcement indicated an increased risk of suicidality when using anti-epileptic agents such as divalproex. The aim of this study is to investigate the effect of divalproex on suicide risk in patients with bipolar disorder. <br><br>METHODS: A search strategy was used for the PubMed, Embase, ProQuest, ScienceDirect, Cochrane Library, ClinicalKey, Web of Science, and ClinicalTrials.gov until June 13th, 2018. Peer-reviewed observationally clinical studies in humans, investigating the association of divalproex and suicidality in patients with bipolar disorder were included. A random-effects meta-analysis was implemented to calculate the relative risk (RR) and 95% confidence intervals (CIs) for suicidality among patients receiving divalproex and those without. <br><br>RESULTS: Total 6 studies were included in the final meta-analysis. There was no significant difference in the incidence rates (reported as [RR]; 95% CI) of suicide attempts (0.921; 0.383-2.215) or completed suicides (0.607; 0.180-2.043) between participants receiving divalproex vs. no medication. There was no significant difference in the incidence rates of suicide attempts (0.815; 0.453-1.466) or completed suicides (1.009; 0.410-2.484) between participants receiving divalproex and carbamazepine. LIMITATIONS: The significantly heterogeneous sample sources and study design amount the included trials. <br><br>CONCLUSIONS: Treatment with divalproex did not reduce or increase the incidence of suicide-related events in patients with bipolar disorder.<br><br>Copyright © 2018 Elsevier B.V.
