Valproate prophylaxis for migraine induced by selective serotonin reuptake inhibitors.

We report the successful use of valproate in a 44-year-old woman with migraine induced by selective serotonin reuptake inhibitors. Valproate should be considered for those patients who develop serious migraine for the first time, or worsening of previous migraine, after the initiation of treatment with selective serotonin reuptake inhibitors and for whom continued treatment with this class of drugs is important.
