Abstract:
Bupropion is increasingly used for nicotine withdrawal and in the treatment of major depression, especially in bipolar patients. We present the case of a 38-year-old female schizoaffective, rapid-cycling patient treated with bupropion for a depressive episode. After 4 weeks of successful treatment (300 mg/day), the patient developed a circumscribed unilateral impairment of sensory trigeminal nerve function. Symptoms completely recovered after discontinuation of bupropion. When re-exposed to bupropion, mild symptoms reappeared, leading to final discontinuation of bupropion. With this natural on-off-on-off design, a causative role of bupropion for trigeminal impairment in this patient can be assumed. To our knowledge, a similar side-effect of bupropion has not been described to date.
