Carbamazepine is an anticonvulsant agent used primarily to prevent seizures in conditions such as epilepsy. Other anticonvulsant agents include phenobarbital , phenytoin , primidone , and valproic acid . In some cases, combination therapy with two or more anticonvulsant drugs may be used.
Ginkgo The herb ginkgo (Ginkgo biloba) has been used to treat Alzheimer's disease and ordinary age-related memory loss, among many other conditions. This interaction involves potential contaminants in ginkgo, not ginkgo itself. A recent study found that a natural nerve toxin present in the seeds of Ginkgo biloba made its way into standardized ginkgo extracts prepared from the leaves. 1 This toxin has been associated with convulsions and death in laboratory animals. 2,3,4 Fortunately, the detected amounts of this toxic substance are considered harmless. 5 However, given the lack of satisfactory standardization of herbal formulations in the US, it is possible that some batches of product might contain higher contents of the toxin depending on the season of harvest. In light of these findings, taking a ginkgo product that happened to contain significant levels of the nerve toxin might theoretically prevent an anticonvulsant from working as well as expected.
