Certain anticonvulsant drugs could be associated with an increased risk of suicide, attempted suicide or violent death. Anticonvulsants are used to help people with epilepsy but can also be prescribed for bipolar disorder, mania, neuralgia, migraine and neuropathic pain. Researchers from Harvard Medical School analyzed data from 14 states about patients fifteen-years old and over who started taking anticonvulsants between July 2001 and December 2006. They found that the risk of suicidal acts was increased for gabapentin (Neurontin), lamotrigine (Lamictal), oxcarbazapine (Trileptal), tiagabine (Gabitril) and valproate (Depakote).
