1. WHAT NEURONTIN IS AND WHAT IT IS USED FOR
Neurontin belongs to a group of medicines used to treat epilepsy and
peripheral neuropathic pain (long lasting pain caused by damage to the
The active substance in Neurontin is gabapentin.
Neurontin is used to treat:
- Various forms of epilepsy (seizures that are initially limited to certain
parts of the brain, whether the seizure spreads to other parts of the brain
or not). Your doctor will prescribe Neurontin for you to help treat your
epilepsy when your current treatment is not fully controlling your
condition. You should take Neurontin in addition to your current
treatment unless told otherwise.
Neurontin can also be used on its own to treat adults and children over
12 years of age.
- Peripheral neuropathic pain (long lasting pain caused by damage to the
nerves). A variety of different diseases can cause peripheral neuropathic
pain (primarily occurring in the legs and/or arms), such as diabetes or
shingles. Pain sensations may be described as hot, burning, throbbing,
shooting, stabbing, sharp, cramping, aching, tingling, numbness, pins
and needles etc.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE NEURONTIN
Do not take Neurontin

ingredients of this medicine (listed in section 6).
Warnings and Precautions
Talk to your doctor or pharmacist before taking Neurontin:
- if you suffer from kidney problems your doctor may prescribe a different
- if you are on haemodialysis (to remove waste products because of
kidney failure), tell your doctor if you develop muscle pain and/or
- if you develop signs such as persistent stomach pain, feeling sick and
being sick contact your doctor immediately as these may be symptoms
of acute pancreatitis (an inflamed pancreas)
Cases of abuse and dependence have been reported for gabapentin from
the post-marketing experience. Talk to your doctor if you have a history of
abuse or dependence.
A small number of people being treated with antiepileptics such as
gabapentin have had thoughts of harming or killing themselves.
If at any time you have these thoughts, immediately contact your doctor.
Important information about potentially serious reactions
A small number of people taking Neurontin get an allergic reaction or
potentially serious skin reaction, which may develop into more serious
problems if they are not treated. You need to know the symptoms to look
out for while you are taking Neurontin.
Read the description of these symptoms in section 4 of this leaflet
under ‘Contact your doctor immediately if you experience any of the
following symptoms after taking this medicine as they can be serious’
Neurontin should not be taken during pregnancy, unless you are told
otherwise by your doctor. Effective contraception must be used by women
of child-bearing potential.
There have been no studies specifically looking at the use of gabapentin in
pregnant women, but other medications used to treat seizures have
reported an increased risk of harm to the developing baby, particularly
when more than one seizure medication is taken at the same time.
Therefore, whenever possible, you should try to take only one seizure
medication during pregnancy and only under the advice of your doctor.
Contact your doctor immediately if you become pregnant, think you might
be pregnant or are planning to become pregnant while taking Neurontin. Do
not suddenly discontinue taking this medicine as this may lead to a
breakthrough seizure, which could have serious consequences for you and
Gabapentin, the active substance of Neurontin, is passed on through
human milk. Because the effect on the baby is unknown, it is not
recommended to breast-feed while using Neurontin.
There is no effect on fertility in animal studies.

Neurontin may produce dizziness, drowsiness and tiredness.
You should not drive, operate complex machinery or take part in other
potentially hazardous activities until you know whether this medication
affects your ability to perform these activities.

told by your doctor that you have an intolerance to some sugars, contact
your doctor before taking this medicinal product.
