What Pendine is used for

Pendine 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.

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

Pendine 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 Pendine 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 Pendine has been prescribed for you.

Your doctor may have prescribed Pendine for another reason.

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

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

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

Pendine is available only with a doctor's prescription.

There is no evidence that Pendine is addictive.

Before you take Pendine

When you must not take it

Do not take Pendine if you are allergic to medicines containing gabapentin (eg. Neurontin) or any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include skin rash, itching or hives; swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing; wheezing or shortness of breath.

Do not take Pendine if the expiry date (EXP) printed on the pack has passed.

If you take this medicine after the expiry date it may not work as well.

Do not take Pendine if the packaging shows signs of tampering or the capsules or tablets do not look quite right.

If you are not sure whether you should start taking this medicine, talk to your doctor or pharmacist.

Before you start to take it

Tell your doctor if you are allergic to:

  • any other medicines, especially barbiturates, or other medicines for epilepsy
  • any other substances, such as foods, dyes or preservatives.

Tell your doctor if you are pregnant or plan to become pregnant.

Pendine may affect your developing baby if you take it during pregnancy. However, it is important to control your fits while you are pregnant.

Your doctor will discuss the risks and benefits of taking Pendine during pregnancy.

Tell your doctor if you are breastfeeding or wish to breastfeed.

Pendine is not recommended for use when breastfeeding as it passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of taking Pendine when breastfeeding.

Tell your doctor if you have any medical conditions, especially the following:

  • kidney problems
  • mixed seizure disorders, including absence seizures.

Your doctor may want to take special care if you have any of these conditions.

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

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines may be affected by Pendine, or may affect how well it works. These include:

  • some medicines used to treat stomach or duodenal ulcers, such as cimetidine (eg. Tagamet, Magicul)
  • morphine, a medicine used to relieve severe pain
  • antacids, medicines used to relieve heartburn and indigestion.
Avoid taking antacids at the same time as Pendine.
Antacids may reduce the absorption of Pendine.

Your doctor or pharmacist can tell you what to do if you are taking any of these medicines.

If you are not sure whether you are taking any of these medicines, check with your doctor or pharmacist.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Pendine.

How to take Pendine

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 or tablets 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 Pendine 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 Pendine

Swallow the capsules or tablets whole with a full glass of water.

When to take Pendine

Take Pendine at about the same time each day.

Taking Pendine 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 Pendine 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 Pendine.

The absorption of Pendine may be reduced if taken with antacids.

Pendine can be taken with or without food.

If you forget to take Pendine

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 Pendine for

Keep taking Pendine for as long as your doctor recommends.

Pendine helps control your condition, but does not cure it. Therefore, to properly control your condition, Pendine 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 Pendine.

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

You may need urgent medical attention.

If you take too much Pendine, you may feel drowsy, weak, unsteady when walking, have diarrhoea, slurred speech or double vision.

Pendine may affect the results of some tests.

Things you must not do

Do not stop taking Pendine, 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 Pendine 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 Pendine completely.

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

Do not give Pendine to anyone else, even if they have the same condition as you.

Things to be careful of

Be careful driving or operating machinery until you know how Pendine affects you.

Pendine may cause drowsiness, dizziness, lightheadedness or affect alertness in some people. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.

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