EPIDIOLEX is indicated for the treatment of seizures associated with Dravet syndrome and Lennox-Gastaut syndrome, two severe forms of epilepsy, in patients two years of age and older.
The exact mechanism by which EPIDIOLEX exerts its anticonvulsant effects is not fully understood. Unlike THC, it does not appear to work through interaction with cannabinoid receptors.
Common side effects may include drowsiness, fatigue, and decreased appetite. It may interact with other medications metabolized by the liver. Always follow dosing instructions provided by a healthcare provider.
