Pregabalin affects chemicals and nerves in the body that are involved in the cause of seizures and some types of pain. The exact way that it works is unknown.

Pregabalin is used with other drugs in the treatment of some types of seizures. It is also used for the management of postherpetic neuralgia (nerve pain caused by the herpes virus or shingles) and for diabetic peripheral neuropathy (pain from damaged nerves that happen with diabetes).

As of June 21, 2007, Pregabalin® (pregabalin) has been approved by the FDA for treatment of FM. The effectiveness of Pregabalin® in treating FM was established in two clinical trials. Pregabalin was used for the reduction of fibromyalgia symptoms, patients showed significant improvement in pain, sleep, fatigue and quality of life. Pregabalin is a structural derivative of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter. Manufactured by Pfizer, Inc., Pregabalin has received FDA approval for the treatment of diabetic neuropathic pain, postherpetic neuralgia and the adjunctive treatment of partial onset seizures in adults with epilepsy.

If you are taking Pregabalin for seizures, do not stop taking Pregabalin even if you feel better. It is important to continue taking the medication to prevent seizures from recurring.
