Gapentin is used to control epilepsy in stabilised patients.

Epilepsy is a condition where you have repeated seizures (fits). There are many different types of seizures, ranging from mild to severe.

Gapentin is also used to treat neuropathic pain, a type of pain caused by damage to the nerves.

Gapentin belongs to a group of medicines called anticonvulsants.

This medicine is thought to work by controlling brain chemicals which send signals to nerves to help control seizures or neuropathic pain.

Gapentin also has pain relieving effects.

Ask your doctor if you have any questions about why Gapentin has been prescribed for you.

Your doctor may have prescribed it in addition to your current therapy when your current treatment is no longer working as well.

Your doctor may have prescribed it for another reason.

Gapentin may lead to dependence on this medicine.
