1 Introduction As potent central nervous system (CNS) depressants, benzodiazepines induce sedation and are used to medically manage insomnia, anxiety, muscle spasms, seizures and alcohol withdrawal [1, 2]. When benzodiazepines are taken concomitantly with other CNS depressants or at high doses this may lead to potentially fatal toxicity [3, 4]. Prolonged use increases tolerance and the risk for dependence, and when discontinued, severe and potentially fatal withdrawal symptoms can occur [5, 6].
