Off-label use (meaning not indicated on the U.S. Food and Drug Administration-approved packaging) includes restless legs syndrome, sleepwalking, and social phobia in adults.

Klonopin has been prescribed for a number of neurological conditions, such as epilepsy and anxiety, since the 1950s and 1960s. Klonopin was originally brought to market in 1975 to treat epileptic seizures.
