What Chemmart Gabapentin is used for
This medicine is used to treat:
- epilepsy, a condition that causes repeated seizures (fits). There are many different types of seizures, ranging from mild to severe
- neuropathic pain (pain due to nerves being damaged or affected).
This medicine belongs to a group of medicines called anticonvulsants.
It is thought to work by controlling brain chemicals which send signals to nerves so that seizures do not happen.
This medicine also has analgesic effects.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
It is available only with a doctor's prescription.
There is not enough information to recommend the use of this medicine for children under the age of 3 years to control epilepsy, or for children under the age of 18 years for neuropathic pain.

Gabapentin 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 this medicine, your doctor can help you decide whether or not to take it during pregnancy.
Tell your doctor if you are breast-feeding or plan to breast-feed.
Your doctor will discuss the possible risks and benefits of using this medicine during breast-feeding. If you do breast-feed, watch your baby carefully. If your baby develops a skin rash or has unusual symptoms, don't breast-feed again until you speak to your doctor.
If you have not told your doctor about any of the above, tell him/her before you start taking gabapentin.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and gabapentin may interfere with each other. These include:
- cimetidine, a medicine used to treat stomach or duodenal ulcers, or reflux
- antacids, medicines used to treat heartburn or reflux.
These medicines may be affected by gabapentin, or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines.

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.

How much to take
Your doctor will tell you how many capsules you will 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 gabapentin and slowly increase the dose to the lowest amount needed to control your epilepsy or neuropathic pain.
How to take it
Swallow gabapentin capsules whole with a full glass of water.
When to take it
Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before or after food.
If you need to take an antacid, take it at least 2 hours before or 2 hours after your dose of gabapentin.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
This medicine helps control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
If you forget to take it
If you have missed a dose by more than 4 hours, skip the dose you missed and take your 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 that 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 your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to the Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much gabapentin. Do this even if there are no signs of discomfort or poisoning.
