Pregabalin is a medication that is primarily used to treat epilepsy, neuropathic pain, anxiety disorders, and fibromyalgia. It is sold under the brand name Lyrica.
Pregabalin works by binding to a specific type of calcium channel in the central nervous system, which reduces the release of neurotransmitters such as glutamate, substance P, and norepinephrine. This helps to calm overactive nerve signals that can cause pain, seizures, and anxiety.
Pregabalin is available in capsule form and is usually taken orally with or without food. The dosage may vary depending on the condition being treated and the individual's response to the medication. It's important to take the medication as prescribed by the doctor and not to stop taking it abruptly, as this can cause withdrawal symptoms.
Common side effects of pregabalin include dizziness, drowsiness, dry mouth, blurred vision, weight gain, and difficulty concentrating. More serious side effects may include mood changes, confusion, depression, and suicidal thoughts. It is important to contact a healthcare provider immediately if any concerning symptoms arise.
Pregabalin is classified as an anticonvulsant medication or an antiepileptic drug because of its ability to reduce seizures. It is also classified as a Schedule V controlled substance in the United States due to its potential for abuse and dependence.
