1. Why am I using NEURONTIN?

NEURONTIN contains the active ingredient gabapentin. NEURONTIN belongs to a group of medicines called anticonvulsants.

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

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

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

NEURONTIN also has pain relieving effects.

Your doctor may have prescribed NEURONTIN in addition to other medicines that you may be taking. This may be necessary if your current treatment is no longer working as well.

Your doctor may have prescribed NEURONTIN for another reason.

NEURONTIN may lead to dependence on this medicine.

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

Use in children

There is not enough information to recommend the use of this medicine in children:

  • under the age of 3 years to control epilepsy, or
  • under the age of 18 years to treat neuropathic pain.

2. What should I know before I use NEURONTIN?

Warnings

When you must not take NEURONTIN

Do not take NEURONTIN if:

  • you are allergic to gabapentin, or any of the ingredients listed at the end of this leaflet. Some of the symptoms of an allergic reaction may include:
    – shortness of breath
    – wheezing or difficulty breathing
    – swelling of the face, lips, tongue or other parts of the body
    – rash, itching or hives on the skin.
  • Always check the ingredients to make sure you can use this medicine.
  • the expiry date printed on the pack has passed or if the packaging is torn or shows signs of tampering.

Check with your doctor if you:

  • have allergies to any other medicines, especially barbiturates or any other anticonvulsant medicines or any other substances, such as foods, preservatives or dyes.
  • have any other medical conditions:
    – kidney problems
    – mixed seizure disorders that include absence seizures.
  • take any medicines for any other condition.
  • have a history of drug abuse and/or psychiatric disorders.
    – NEURONTIN poses risks of abuse and dependence. Your body may become used to you taking NEURONTIN and this may result in physical dependence. It means that you may experience withdrawal symptoms if you stop taking NEURONTIN suddenly. So it is important to strictly follow the directions given by your doctor.
  • are pregnant or plan to become pregnant.
  • are breast-feeding or plan to breast-feed.
  • if you notice any of the symptoms related to these serious skin reactions described in section 6 under table titled “Serious side effects”, stop using gabapentin and seek medical attention immediately.
    – Serious skin rashes including Stevens-Johnson syndrome, toxic epidermal necrolysis and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in association with gabapentin.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

NEURONTIN may affect your developing baby if you take it during pregnancy. However, it is very important to control your fits while you are pregnant. If it is necessary for you to take NEURONTIN, your doctor can help you decide whether or not to take it during pregnancy.

NEURONTIN passes into breast milk. The effect on your breast-fed baby is unknown.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

If you do breast-feed, watch your baby carefully.

If your baby develops a skin rash, becomes sleepy or has unusual symptoms, don’t breast-feed again until you speak to your doctor.

Your doctor can discuss the risks and benefits of breast-feeding with you.

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking NEURONTIN.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including all prescription, any medicines, vitamins or herbal supplements or natural therapies that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with NEURONTIN and affect how it works.

Some medicines may be affected by NEURONTIN or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines. Your doctor or pharmacist will advise you accordingly.

NEURONTIN and certain other medicines may influence each other.

Using NEURONTIN with other medicines that can make you feel drowsy, such as sleeping tablets and other pain relievers (e.g. benzodiazepines and opioids), antihistamines, antidepressants, antipsychotics, cannabis, and alcohol may result in severe drowsiness, decreased awareness, breathing problems, coma and death.

Your doctor will minimise the dose and duration of use; and monitor you for signs and symptoms of breathing difficulties and sedation.

Tell your doctor or pharmacist if you are taking any of the following:

  • cimetidine, a medicine used to treat stomach or duodenal ulcers
  • antacids, medicines used to treat heartburn or reflux
  • opioids, medicines used to treat severe pain e.g. morphine.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect NEURONTIN. Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking NEURONTIN.

4. How do I use NEURONTIN?

Follow all directions given to you by your doctor or pharmacist carefully.

They may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

How much to take

  • Your doctor will tell you how many capsules/tablets you need to take each day. This may depend on your age, your condition and whether or not you are taking any other medicines.
  • Your doctor may recommend that you start with a low dose of NEURONTIN and slowly increase the dose to the lowest amount needed to control your epilepsy/convulsions or neuropathic pain.
  • Follow the instructions provided and use NEURONTIN until your doctor tells you to stop.

How to take NEURONTIN

  • Swallow NEURONTIN whole with a full glass of water.
  • NEURONTIN tablets can be divided in half along the breakline, if advised by your doctor or pharmacist.

When to take NEURONTIN

  • NEURONTIN should be used at about the same time each day.
  • Taking NEURONTIN at the same time each day will have the best effect. It will also help you remember when to take the capsules/tablets.
  • If you are taking NEURONTIN three times a day, do not allow more than 12 hours between doses.
  • It does not matter if you take NEURONTIN before or after food.

How long to take NEURONTIN

  • Continue taking your medicine for as long as your doctor tells you to.
  • NEURONTIN helps control your condition but does not cure it. Therefore, you must take your medicine every day, even if you feel well.
  • Do not stop taking NEURONTIN, or lower the dose, without checking with your doctor. Do not let yourself run out of medicine over the weekend or holidays.
  • Stopping NEURONTIN suddenly may worsen your condition or increase your chance of experiencing withdrawal symptoms, such as sleeplessness, headache, nausea (feeling sick), anxiety, excessive sweating or diarrhoea (runny stools). If appropriate, your doctor will slowly reduce your dose before you can stop taking it completely.

If you forget to use NEURONTIN

NEURONTIN should be used regularly at the same time each day. If you miss your dose at the usual time, take it as soon as you remember, and then go back to taking NEURONTIN as you would normally.

Otherwise if it is almost time for your next dose (within 4 hours), skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

  • This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take NEURONTIN, ask your pharmacist for help.

If you take too much NEURONTIN

If you think that you or anyone else may have taken too much NEURONTIN, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (Australia telephone 13 11 26) for advice, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Symptoms of an overdose may include you falling unconscious, feeling drowsy, weak, unsteady when walking, having double vision, slurred speech or diarrhoea.

5. What should I know while using NEURONTIN?

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking NEURONTIN.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking NEURONTIN.

If you are going to have surgery, or emergency treatment, tell the surgeon or anaesthetist that you are taking NEURONTIN.

If you feel NEURONTIN is not helping your condition, tell your doctor. Your doctor may need to change your medicine.

If, for any reason, you have not taken NEURONTIN exactly as prescribed, tell your doctor. Otherwise, your doctor may change your treatment unnecessarily.

If you need to have any medical tests while you are taking NEURONTIN, tell your doctor. It may interfere with the results of some tests.

Call your doctor straight away if:

  • you have any thoughts of suicide or self-harm, any unusual changes in mood or behaviour, or show signs of depression.
    Some people being treated with anti-epileptics, such as NEURONTIN, have had thoughts of harming or killing themselves.
    Patients and caregivers should be alert and monitor for signs and symptoms of suicide, these include:
    – thoughts or talk of death or suicide
    – thoughts or talk of self-harm or harm to others
    – any recent attempts of self-harm
    – new or an increase in aggressive behaviour, irritability or agitation
    – new onset of or worsening of depression.
    Any mention of suicide or violence must be taken seriously.
  • you or someone you know is demonstrating these warning signs and symptoms of suicide while taking NEURONTIN, contact your doctor or a mental health professional right away.
  • you become pregnant while taking NEURONTIN.

Remind any doctor, dentist or pharmacist, surgeon you visit that you are using NEURONTIN, if you are going to have any surgery or procedure (including dental surgery).

Keep all of your doctor’s appointments so that your progress can be checked.

Your doctor will check your progress and may want to take some tests from time to time. This helps to prevent unwanted side effects.

Things you must not do

  • Do not take NEURONTIN to treat any other complaints unless your doctor tells you to.
  • Do not give NEURONTIN to anyone else, even if their symptoms seem similar to yours or they have the same condition as you.
  • Do not stop taking NEURONTIN or lower the dose without checking with your doctor.

Stopping NEURONTIN suddenly, if you have epilepsy, may cause unwanted side effects or make your condition worse. Your doctor will slowly reduce your dose before you can stop taking it completely.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how NEURONTIN affects you.

As with other anticonvulsant medicines, NEURONTIN may cause drowsiness, dizziness, light-headedness or sleepiness in some people. Make sure you know how you react to NEURONTIN before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed. If this occurs do not drive.

Children should not ride a bike, climb trees or do anything else that could be dangerous if they are feeling drowsy or sleepy.

Drinking alcohol

Tell your doctor if you drink alcohol.

Be careful when drinking alcohol while you are taking NEURONTIN.

Combining NEURONTIN and alcohol can make you more sleepy, dizzy or light-headed. Your doctor may suggest you avoid alcohol while you are being treated with NEURONTIN.

Looking after your medicine

  • Capsules: Store below 30°C.
  • Tablets: Store below 25°C.
  • Keep your capsules/tablets in the pack until it is time to take them. If you take the capsules/tablets out of the pack, they may not keep well.

Follow the instructions in the carton on how to take care of your medicine properly.

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Getting rid of any unwanted medicine

If you no longer need to use this medicine, your doctor or pharmacist tells you to stop taking, it is out of date or damaged, take it to any pharmacy for safe disposal.

Do not use this medicine after the expiry date.

6. Are there any side effects?

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking NEURONTIN.

All medicines can have side effects. If you do experience any side effects, most of them are minor and temporary. However, some side effects may need medical attention.

It can be difficult to tell whether side effects are the result of taking NEURONTIN; of your condition; or side effects of other medicines you may be taking, for this reason it is important to tell your doctor of any change in your condition.

If you are over 65 years of age you may have an increased chance of getting side effects.

See the information below and, if you need to, ask your doctor or pharmacist if you have any further questions about side effects.

If you get any side effects, do not stop taking NEURONTIN without first talking to your doctor or pharmacist.
