Gabapentin is an anti-epileptic drug, also called an anticonvulsant. It affects chemicals and nerves in the body that are involved in the cause of seizures and some types of pain.

WHAT IS GABAPENTIN AND HOW DOES IT WORK?
Gabapentin is a prescription drug most commonly prescribed to relieve nerve pain following shingles in adults, treating the pain of post herpetic neuralgia. Gabapentin belongs to a class of drugs known as anti-seizure drugs.
Take gabapentin by mouth as directed by your doctor, usually once a day with the evening meal. The dosage is based on your medical condition and response to treatment.
Swallow gabapentin whole. Do not crush or chew sustained-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split sustained-release tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
During the first 2 weeks of treatment, your doctor may gradually increase your dose so your body can adjust to the medication.
