What is Lyrica CR?

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

Lyrica CR is a prescription medicine used to treat pain caused by damaged nerves in people with diabetes (diabetic neuropathy). Lyrica CR is also used to treat pain caused by damaged nerves (neuropathic pain) that follows healing of shingles (herpes zoster). This condition is called post-herpetic neuralgia.

It is not known if Lyrica CR is effective when used for the treatment of fibromyalgia, or when taken with other seizure medicines for adults with partial onset seizures.

Lyrica CR is supplied as extended-release tablets in the following strengths: 82.5 mg, 165 mg, and 330 mg.
