Does pyridoxine control behavioral symptoms in adult patients treated with levetiracetam? Case series from UAE

Epilepsy Behav Case Rep. 2015 Sep 27;4:94-5. doi: 10.1016/j.ebcr.2015.08.003. eCollection 2015.


Behavioral symptoms are known side effects of levetiracetam. Previous case series in children and adolescents have demonstrated the potential effect of pyridoxine in ameliorating these symptoms. We retrospectively reviewed the charts of 51 patients treated with pyridoxine to control agitation and irritability following the introduction of levetiracetam. These symptoms were relieved in 34 patients (66.6%). Seventeen patients did not appear to benefit from this supplementation. This preliminary study suggests that pyridoxine might be an effective option across all ages for patients suffering from levetiracetam-induced behavioral side effects.
