Vertical gaze palsy due to medication error

We present a teenage boy with recent onset of seizures, who was erroneously treated with a large dose of an anti-epileptic medication as a result of drug mix-up. The ensuing drug toxicity caused vertical gaze palsy, an unusual manifestation related to overdose of the agent. Timely recognition of the error and discontinuation of the drug resulted in complete recovery to baseline.
