Clinically, ethambutol (EMB)-induced psychosis is rare. In our review of the literature, most cases of antituberculosis agent-associated psychoses were caused by isoniazid (INH). We report the case of a 51-year-old man with suspected tuberculosis (TB) pleurisy. An anti-TB trial with INH, rifampicin and EMB was given initially. Dizziness, disorientation, and auditory and visual hallucinations developed after seven days of therapy. Laboratory examinations, including routine biochemistry tests, serum titer of antinuclear antibodies, cerebrospinal fluid analysis and computerized tomography of the head showed no abnormal findings. Following discontinuation of anti-TB agents, the psychiatric symptoms subsided. When the patient was challenged with EMB, the same psychiatric symptoms recurred, but resolved again after discontinuation of EMB. It is important to be aware that EMB can induce psychosis when anti-TB medications are prescribed.

Lacosamide (LCM) is a newer antiepileptic drug with a favorable safety profile used in partial epilepsy as adjunctive therapy. The most common side effects include dizziness, headache, confusion, diplopia, nausea, nasopharyngitis, and vomiting. Although sporadic cases of drug-induced psychosis have been reported for some antiepileptic drugs, this was not the case for LCM. We describe the first case of LCM-induced psychosis in a patient with drug-resistant partial epilepsy during the first week of treatment initiation, stressing the importance of clinicians remaining alert for abnormal behavioral symptoms.
