Potiga, a potassium channel opener, was approved in 2011 as an adjunctive treatment for partial-onset seizures in patients with inadequate response to alternative treatments and for whom the benefits outweigh the risk of retinal abnormalities and potential decline in visual acuity. In 2013, the labeling for Potiga was updated to include a boxed warning regarding the risk of permanent retinal abnormalities, potential vision loss, and skin discoloration.
