Gabapentin — Uses, Dosage, Side Effects & Safety

Drug class: Neurology

Overview

Gabapentin is a prescription medication used to treat nerve pain (neuropathic pain) caused by conditions such as shingles (postherpetic neuralgia) and to control certain types of seizures in epilepsy. It is also sometimes prescribed for restless legs syndrome and other off-label uses. Gabapentin works by affecting chemicals and nerves in the body that are involved in the cause of seizures and some types of pain. It does not cure epilepsy or the underlying cause of nerve pain but helps reduce symptoms. Key points for patients: Gabapentin should be taken exactly as prescribed. Do not stop taking it suddenly without consulting your doctor, as this may increase the risk of seizures or withdrawal symptoms. Always inform your healthcare provider about all medications you are taking to avoid interactions.
