Clonazepam

Clonazepam, sold under the brand name Klonopin among others, is a benzodiazepine medication used to prevent and treat anxiety disorders, seizures, agitation associated with psychosis, obsessive–compulsive disorder (OCD), and akathisia, with some evidence supporting use in treatment of bipolar mania. It is a long-acting benzodiazepine. It possesses anxiolytic, anticonvulsant, sedative, hypnotic, and skeletal muscle relaxant properties. It is typically taken orally (swallowed by mouth) but is also used intravenously. Effects begin within one hour and last between eight and twelve hours in adults. Common side effects may include sleepiness, weakness, poor coordination, difficulty concentrating, and agitation. Clonazepam may also decrease memory formation. Long-term use may result in tolerance, dependence, and life-threatening withdrawal symptoms if stopped abruptly.
