Vigabatrin is a second-generation antiepileptic drug characterized by a few antiepileptic indications, with a very good interaction profile in polytherapy. Clinically relevant adverse effects (especially visual field defects) have reduced its use as antiepileptic drug in routine clinical practice considerably. Vigabatrin has an acceptable behavioural tolerability profile, although patients with epilepsy treated with this medication can report depression, psychosis, and irritability. Risk factors for developing psychiatric adverse effects include high starting and maintenance doses, past psychiatric history, and epilepsy severity. Vigabatrin has no approved indications or clinical uses in psychiatry, despite weak evidence for its usefulness in the treatment of anxiety disorders and addictions.
