What Nupentin is used for

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

Nupentin is also used in the treatment of neuropathic pain, a type of pain caused by damage to the nerves.

Nupentin belongs to a group of medicines called anticonvulsants. These medicines work by controlling brain chemicals which send signals to nerves to help control seizures or neuropathic pain.

Your doctor may prescribe Nupentin in addition to your current therapy when your treatment is no longer working as well.

Ask your doctor if you have any questions about why Nupentin has been prescribed for you. Your doctor may have prescribed Nupentin for another reason.

Nupentin is available only with a doctor's prescription.

There is no evidence that Nupentin is addictive.

Use in Children

Nupentin is not recommended for use in children under the age of:

  • 3 years old to control epilepsy
  • 18 years old for the treatment of neuropathic pain.

The safety and effectiveness of Nupentin in children of these age groups have not been established.

How to take Nupentin

Follow all directions given to you by your doctor and 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

The dose varies from person to person.

Your doctor will tell you how many capsules you need to take each day and when to take them. This depends on your age, condition and whether or not you are taking any other medicines.

Your doctor may recommend that you start with a low dose of Nupentin and slowly increase the dose to the lowest amount needed to control your condition.

People with kidney problems and/or undergoing haemodialysis may need smaller doses.

How to take Nupentin

Swallow the capsules whole with a full glass of water.

When to take Nupentin

Take Nupentin at about the same time each day. Taking Nupentin at the same time each day will have the best effect. It will also help you to remember when to take it.

If you are taking Nupentin three times a day, do not allow more than 12 hours to pass between doses.

If you need to take an antacid, take it at least 2 hours before, or 2 hours after taking your dose of Nupentin. The absorption of Nupentin may be reduced if taken with antacids.

Nupentin can be taken with or without food.

If you forget to take Nupentin

If you have missed a dose by more than 4 hours, skip the dose you missed and take the next dose when you are meant to.

Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose you missed. This may increase your chance of 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 your medicine, ask your pharmacist for some hints.

How long to take Nupentin for

Keep taking Nupentin for as long as your doctor recommends. Nupentin helps control your condition, but does not cure it. Therefore, to properly control your condition, Nupentin must be taken every day.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Nupentin.

Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention. If you take too much Nupentin, you may feel drowsy, weak, unsteady when walking, have diarrhoea, slurred speech or double vision.

If you need to have any medical tests, tell your doctor that you are taking Nupentin. Nupentin may affect the results of some tests.

Visit your doctor regularly so they can check on your progress. Your doctor may want you to have some tests from time to time. This helps to prevent unwanted side effects.

Things you must not do

Do not stop taking Nupentin, or lower the dose, without checking with your doctor. Do not let yourself run out of medicine over weekends or during holidays. If you stop taking Nupentin suddenly, your condition may become worse. You may also feel anxious, sick (nauseous), have pains, sweat or have trouble sleeping.

Your doctor will tell you how to gradually reduce your dose before you can stop taking Nupentin completely.

Do not use Nupentin to treat any other conditions unless your doctor tells you to.

Things to be careful of

Be careful driving or operating machinery until you know how Nupentin affects you. Nupentin may cause drowsiness, dizziness, lightheadedness, tiredness, drowsiness or affect alertness in some people. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.

Be careful when drinking alcohol while you are taking Nupentin. Combining Nupentin and alcohol can make you more sleepy, dizzy or lightheaded. You doctor may suggest you avoid alcohol while you are taking Nupentin.
