6. Further information
Neurontin belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long lasting pain caused by damage to the nerves).
The active ingredient 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.
Do not take Neurontin
• □ if you are allergic (hypersensitive) to gabapentin or any of the
other ingredients of Neurontin
Take special care with Neurontin:
• if you suffer from kidney problems your doctor may prescribe a different dosing schedule
• if you are on haemodialysis (to remove waste products because of kidney failure), tell your doctor if you develop muscle pain and/or weakness
• 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)
A small number of people being treated with anti-epileptics 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’ Muscle weakness, tenderness or pain and particularly, if at the same time, you feel unwell or have a high temperature it may be caused by an abnormal muscle breakdown which can be life-threatening and lead to kidney problems. You may also experience discoloration of your urine, and a change in blood test results (notably blood creatine phosphokinase increased). If you experience any of these signs or symptoms, please contact your doctor immediately.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Medicines containing morphine
If you are taking any medicines containing morphine, please tell your doctor or pharmacist as morphine may increase the effect of Neurontin.
Antacids for indigestion
If Neurontin and antacids containing aluminium and magnesium are taken at the same time, absorption of Neurontin from the stomach may be reduced. It is therefore recommended that Neurontin is taken at the earliest two hours after taking an antacid.
Neurontin:
• is not expected to interact with other antiepileptic drugs or the oral contraceptive pill.
• may interfere with some laboratory tests, if you require a urine test tell your doctor or hospital what you are taking.
Pregnancy
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 your baby.
Breast feeding
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.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
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.
Important information about some of the ingredients of Neurontin
Neurontin hard capsules contain lactose (a type of sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

Children aged 6 years and above:

The treatment is started with a low initial dose which is gradually increased over a period of approximately 3 days. The usual dose to control epilepsy is 25-35 mg per kg of body weight per day. It is usually given in 3 separate doses, by taking the capsule(s) or tablet(s) each day, usually once in the morning, once in the afternoon and once in the evening.

Higher than recommended doses may result in an increase in side effects including loss of consciousness, dizziness, double vision, slurred speech, drowsiness and diarrhoea. Call your doctor or go to the nearest hospital emergency unit immediately if you take more Neurontin than your doctor prescribed. Take along any capsules or tablets that you have not taken, together with the container and the label so that the hospital can easily tell what medicine you have taken.
If you forget to take Neurontin
If you forget to take a dose, take it as soon as you remember unless it is time for your next dose. Do not take a double dose to make up for a forgotten dose.
If you stop taking Neurontin
