1. What Gabapentin is and what it is used for

Gabapentin is used as an anticonvulsant for the treatment of various types of epilepsy. It is used to reduce the risk of an epileptic fit or to stop one that is in progress.

Anticonvulsant drugs stop the excessive electrical activity in your brain which is causing epileptic fits. You should take gabapentin in addition to your current treatment unless your doctor tells you otherwise. It can also be used on its own to treat adults and children over 12 years of age.

Gabapentin belongs to a group of medicines used to treat chronic (long lasting) pain caused by damage to the nerves. This pain is known as peripheral neuropathic pain. Peripheral neuropathic pain is caused by a variety of diseases such as diabetes, shingles, trauma or diseases of the nervous system. Pain sensations may be described as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, pins and needles etc.

Your doctor will have explained the reason for prescribing gabapentin capsules to you.
