Lyrica (pregabalin) is a schedule V drug, classified as a CNS depressant. The potential for abuse of pregabalin is significantly less than the potential with benzodiazepines (Xanax, Valium, etc), but it is abused by some.
It can cause dependency and withdrawal effects after long-term use. The withdrawal is similar to benzodiazepine withdrawal, but not as severe.
It should be reduced gradually when finishing treatment.
