Mania associated with clonazepam.
Clonazepam is a potent, long-acting benzodiazepine approved for use in myoclonic and petit mal seizures. Initial reports have demonstrated encouraging results with clonazepam in the treatment of acute mania as well as a favorable side-effect profile. A trial of adjunctive clonazepam was initiated in a 41-year-old patient with chronic schizophrenia. Two weeks later, while on an 8-mg dosage, he became manic, developing pressured speech, euphoria, inflated esteem, agitation, and insomnia. Initiation of electroconvulsive therapy with gradual tapering and discontinuation of the clonazepam resulted in amelioration of the manic episode and a return to his previous clinical status. Clinicians should be alerted to the potential of clonazepam to cause manic-like behavior in susceptible patients.
