What Lamotrigine GH is used for
Lamotrigine (the active ingredient in Lamotrigine GH) belongs to a group of medicines called "anti-epileptic drugs".
Lamotrigine GH are used for the treatment of epilepsy in adults and children over 12 years of age.
Lamotrigine GH is initially used in addition to other medicines for the treatment of epilepsy. Lamotrigine GH is also used in partial or generalised seizures including tonic-clonic seizures and seizures associated with Lennox-Gastaut Syndrome.
An epileptic seizure, fit or turn results when abnormal electrical impulses occur in nerve cells in the brain. These abnormal electrical impulses are believed to be due to altered levels of some chemicals in the brain.
It is thought that Lamotrigine GH work by changing the levels of some of the chemicals associated with seizures.
Your doctor may have prescribed Lamotrigine GH for another reason. Ask your doctor if you have any questions about why Lamotrigine GH has been prescribed for you.
There is no evidence that Lamotrigine GH is addictive.
Before you take Lamotrigine GH
When you must not take it
Do not take Lamotrigine GH if you have ever had an allergic reaction to:
- any of the ingredients listed at the end of this leaflet.
Symptoms of an allergic reaction may be mild or severe. They usually include some or all of the following:
- swelling of the lips/mouth;
- difficulty in breathing;
- lumpy rash ("hives");
Do not take Lamotrigine GH after the expiry date printed on the pack. If you take Lamotrigine GH after the expiry date has passed, they may not work as well.
Do not take Lamotrigine GH if the packaging is torn or shows signs of tampering. If you're not sure whether you should be taking Lamotrigine GH, talk to your doctor.
Before you start to take it
You must tell your doctor if you are pregnant or trying to become pregnant. Lamotrigine GH may affect your unborn baby if you take it during pregnancy, but it is still important that you control your fits while you are pregnant.
Your doctor will discuss the risks and benefits of taking Lamotrigine GH during pregnancy and help you decide whether or not you should take Lamotrigine GH.
It is recommended that women on antiepileptic medicines, such as Lamotrigine GH, receive pre-pregnancy counselling with regard to the risk on their unborn child.
Studies have shown a decrease in the levels of folic acid during pregnancy with Lamotrigine GH. It is therefore recommended that you take a folate supplement, eg. 5 mg folate daily, before becoming pregnant and during the first 12 weeks of your pregnancy.
You must tell your doctor if you are breastfeeding or wish to breastfeed. Lamotrigine GH is thought to pass into breast milk.
Your doctor will discuss the risks and benefits of using Lamotrigine GH if you are breastfeeding.
You must also tell your doctor if:
- you are allergic to foods, dyes, preservatives or any other medicines;
- you have a history of allergy or rash to other antiepileptic medicines;
- you are suffering, or have ever suffered, from any liver or kidney disorders;
- you have Parkinson's Disease;
- you are taking any other medicines for epilepsy. This is particularly important for sodium valproate ("Epilim" or "Valpro"), carbamazepine (''Tegretol"), phenobarbitone or primidone ("Mysolfne");
- you are taking oral contraceptives (birth control pills) or other female hormone therapy (eg. hormone replacement therapy [HRT]);
- you are taking rifampicin ("Rimycin" or "Rifadin"), a medicine used to treat bacterial infections;
- you are taking any other medicines that you buy with or without a prescription from a pharmacy, supermarket or health food shop.
Taking other medicines
Some medicines may affect the way other medicines work. Your doctor or pharmacist will be able to tell you what to do when taking Lamotrigine GH with other medicines.
Your doctor will have a complete list of the medicines that may cause problems when taken with Lamotrigine GH.
Make sure that your doctor is aware of any of the above before you start taking Lamotrigine GH.
How to take Lamotrigine GH
Using Lamotrigine GH for the first time
You may notice that you feel dizzy, tired, or unsteady in the first few weeks of treatment with Lamotrigine GH. During this period you may also notice that you have slight problems with your vision such as blurred or double vision. As your reactions may be slower during this period you should not operate any machinery or appliances and you should not drive a car. If any of these effects do not go away or are troublesome you should see your doctor.
If you develop any skin rash (eg. spots or 'hives') during Lamotrigine GH treatment contact your doctor immediately.
There have been reports of life-threatening skin rash associated with Lamotrigine GH treatment, particularly in children. Lamotrigine GH should be discontinued at the first sign of rash unless the rash is clearly not drug related.
If you have any questions about taking Lamotrigine GH ask your doctor or pharmacist.
How much to take
Take Lamotrigine GH as directed by your doctor or pharmacist. Never change the dose yourself.
Do not increase the dose more quickly than you have been told.
Your doctor and pharmacist will be able to tell you:
- how many tablets to take at each dose.
- how many doses to take each day.
- when to take each of your doses.
The label on the container that the tablets were supplied in will give the same information. If there is something that you do not understand ask either your doctor or pharmacist.
It is usual for the dose of Lamotrigine GH to start at quite a low level and be slowly increased during the first few weeks of treatment. The doses that your doctor prescribes will generally depend on any other anti-epileptic medications you are taking, and your response to Lamotrigine GH.
If you are about to start or stop taking contraceptive pills while taking Lamotrigine GH, your doctor may need to adjust the dose of Lamotrigine GH depending on how well your condition is being treated.
You should tell your doctor if there are any changes in your menstrual pattern, such as breakthrough bleeding.
Your doctor may need to change the dose of Lamotrigine GH during your pregnancy.
Children's weight should be checked and the dose reviewed as weight changes occur.
If you have any questions about the dose that you have been prescribed you should ask your doctor or pharmacist.
How to take it
Lamotrigine GH may be swallowed whole or dispersed in a small volume of water (at least enough to cover the whole tablet).
Lamotrigine GH are not chewable tablets.
If you have any questions about how to take Lamotrigine GH ask your doctor or pharmacist.
How long to take it
Continue taking Lamotrigine GH for as long as your doctor tells you to. Lamotrigine GH help control your condition but does not cure it. Therefore you must take your medicine every day, even if you feel well.
If you forget to take it
If you have forgotten to take a dose of Lamotrigine GH, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take a double dose to make up for a dose that you missed. If you are not sure what to do, ask your doctor or pharmacist. If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately contact your doctor or the Australian Poisons Information Centre (13 11 26) for advice, or go to the Accident and Emergency department at your nearest hospital, if you think that you or anyone else may have taken too many Lamotrigine GH. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Keep telephone numbers for these places handy.
If you are not sure what to do, contact your doctor or pharmacist.
If too many Lamotrigine GH have been taken it is likely that the following symptoms will be experienced:
- problems with eyesight;
- impaired consciousness;

Symptoms usually include some or all of the following:
Potentially serious skin reaction
A small number of people taking Lamotrigine GH get an allergic reaction or potentially serious skin reaction, which may develop into more serious problems if they are not treated. Severe allergic reactions are rare.
These symptoms are more likely to happen during the first few months of treatment with Lamotrigine GH, especially if the dose is too high or if the dose is increased too quickly, or if Lamotrigine GH is taken with a medicine called valproate. Serious skin reactions are more common in children. Symptoms of these serious allergic reactions include:
- any skin reaction, eg. rash or 'hives';
- wheezing, difficulty in breathing;
- swelling of the face, lips or tongue;
- sore mouth or sore eyes;
- swollen glands.
Tell your doctor immediately if you notice any of the above symptoms.
