Use

Pregabalin, known as Lyrica, is an anticonvulsant drug used to treat partial seizures in patients and is a more potent successor to gabapentin. It is commonly prescribed for neuropathic pain and fibromyalgia. The test is useful for monitoring serum pregabalin concentrations, assessing compliance, and adjusting dosage in patients, particularly those with kidney failure who may require lower dosages. It helps in evaluating therapeutic and potentially toxic levels, although exact therapeutic and toxic ranges are not well-defined. The test results should be interpreted in the context of the patient's clinical response and other clinical tests to provide useful information for patients showing poor response, noncompliance, or adverse effects. Toxicity might occur at concentrations above 10 mcg/mL.
