Lyrica (aka: Pregabilin) is a fairly new drug that has been shown to have success with the pain of Fibromyalgia. It is also used for treating pain caused by neurologic diseases such as postherpetic neuralgia as well as seizures. Pregabalin binds to calcium channels on nerves and may modify the release of neurotransmitters (chemicals that nerves use to communicate with each other). Reducing communication between nerves may contribute to pregabalin's effect on pain.
The most common side effects of pregabalin are dizziness, drowsiness, dry mouth, edema (accumulation of fluid), blurred vision, weight gain, and difficulty concentrating. Other side effects include reduced blood platelet counts, and increased blood creatinine kinase levels. Increased creatinine kinase can be a sign of muscle injury, and in clinical trials three patients experienced rhabdomyolysis (severe muscle injury). Therefore, patients should report unexplained muscle pain, tenderness or weakness to their doctors, especially if associated with fever and malaise (reduced well-being). Pregabalin has rarely been associated with angioedema (swelling of the face, tongue, lips, and gums, throat and larynx).
