It works by slowing down impulses in the brain that cause seizures. It also affects chemicals in the brain that send pain signals across the nervous system. It works in different ways to stop seizures (Epilepsy) and to block pain messages reaching the brain. It is also used to treat Fibromyalgia & neuropathic pain or nerve pain in people with diabetes, herpes zoster (post-herpetic neuralgia) or spinal cord injury. Pregabalin is used with other medications to treat partial onset seizures in adults and children who are at least 1 month old.
