FDA has approved a new boxed warning for the anti-seizure drug ezogabine (Potiga) because of the potential risk of vision loss, retinal abnormalities, as well as skin, nail, mucous membrane, and sclera discoloration. The agency recommends that ezogabine use be limited to individuals who have not responded to alternative therapies for seizure control, and when the benefits of treatment are greater than the risks.
