Pregabalin is an anti-epileptic drug, also called an anticonvulsant. It works by slowing down impulses in the brain that cause seizures. Pregabalin also affects chemicals in the brain that send pain signals across the nervous system.

Pregabalin is used to treat pain caused by fibromyalgia, or nerve pain in people with diabetes (diabetic neuropathy), herpes zoster (post-herpetic neuralgia), or spinal cord injury.

Pregabalin is also used with other medications to treat partial onset seizures in adults and children who are at least 1 month old. Pregabalin may also be used for purposes not listed in this medication guide.
