Five case reports described staring spells and tonic-clonic seizures in patients receiving 10 to 15 mg of aripiprazole.15"19 In the New Drug Application (NDA) for aripiprazole, the incidence of seizures was estimated to be .11% (1 of 926 patients) in placebo-controlled trials and .46% (3 of 859 patients) in haloperidol-controlled trials.
Initial pharmacotherapy for generalized tonic-clonic seizures commonly includes valproic acid, lamotrigine, and topiramate, which are theorized to reduce seizure activity by increasing inhibitory transmitter (GABA) concentrations and decreasing the activation of sodium channels (Goldenberg, 2010).
