Epidiolex is an FDA-approved prescription medication that contains a purified form of CBD. It was approved in 2018 for the treatment of seizures associated with Dravet syndrome and Lennox-Gastaut syndrome in patients aged two years and older. These are two of the most severe and treatment-resistant forms of epilepsy, and Epidiolex offers a new therapeutic option for those who have not responded well to traditional anti-seizure medications.
