There are reports of severe, potentially life-threatening rashes associated with lamotrigine treatment, particularly in children. Lamitan should be discontinued at the first sign of rash unless the rash is clearly not drug related.
What is in this leaflet
This leaflet answers some common questions about LAMITAN. It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking LAMITAN tablets against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What LAMITAN is used for
Lamotrigine (the active ingredient in LAMITAN tablets) belongs to a group of medicines called “anti-epileptic drugs”.
LAMITAN tablets are used to treat epilepsy, including partial or generalised seizures, in adults and children. In general, it is initially used [in addition to other medicines] for treatment of this condition.
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 to work by changing the levels of some of the chemicals associated with seizures.
Ask your doctor if you have any questions about why LAMITAN has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is only available with a doctor's prescription.
There is no evidence that it is addictive.
Before you take it
When you must not take it
Do not take LAMITAN if you are allergic to lamotrigine 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 LAMITAN if the expiry date (Exp.) printed on the pack has passed.
Do not take it if the packaging shows signs of tampering or the tablets do not look quite right.
Before you start to take it
Tell your doctor if you are taking any other medicines that contain lamotrigine.
Tell your doctor if you are allergic to any other medicines or any foods, dyes or preservatives.
Tell your doctor if you have or have had any of the following medical conditions:
- a history of allergy or rash to other anti-epileptic drugs
- liver or kidney disorders
- Parkinson’s disease
- If you have ever developed meningitis after taking lamotrigine
- If you are taking any other medications for epilepsy. This is particularly important for medicines containing sodium valproate.
Tell your doctor if you are pregnant or trying to become pregnant. Your doctor will discuss the risks and benefits of taking LAMITAN tablets if you are pregnant or intending to become pregnant, including the risk to mother and foetus of uncontrolled epilepsy, when deciding on treatment options.
Tell your doctor if you are breast feeding or planning to breast feed. Lamotrigine can pass into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of taking this medicine if you are breast feeding.
If you have not told your doctor about any of the above, tell them before you start taking LAMITAN.

How to take it
Taking LAMITAN for the first time
You may notice that you feel dizzy, tired or unsteady in the first few weeks of treatment with LAMITAN tablets. During this period you may also notice that you have slight problems with your 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.
Contact your doctor immediately if you develop any skin rash (e.g. spots or hives) during LAMITAN treatment. There are reports of severe, potentially life-threatening rashes associated with LAMITAN treatment particularly in children. It should be discontinued at the first sign of rash unless the rash is clearly not drug related.
Ask your doctor or pharmacist if you have any questions about taking LAMITAN.
How much to take
It may take a while to find the best dose of LAMITAN for you. The dose you take will depend on:
- your age and weight
- whether you are taking it with other medications
- whether you have any kidney or liver problems.
Do not increase the dose more quickly than you have been told. Your doctor will prescribe a low dose to start with and gradually increase the dose over a few weeks until you reach a dose that works for you.
Women taking hormonal contraceptives, such as the birth control ‘pill’ may need a higher maintenance dose of this medicine. Your doctor will usually decrease your dose once you stop taking hormonal contraceptives.
Tell your doctor if there are any changes in your menstrual pattern, such as breakthrough bleeding whilst on the ‘pill’. Your doctor may need to change the dose of LAMITAN as the ‘pill’ may not work effectively for contraception whilst taking it.
How long to take it
Do not stop taking LAMITAN or change the dose without first checking with your doctor.
Your doctor will advise you if you need to stop taking this medicine and how to do this gradually over a period of two weeks.
Use in children
Children's weight should be checked and the dose reviewed as weight changes occur.
How to take it
LAMITAN may be swallowed whole, chewed or dispersed in a small volume of water (at least enough to cover the whole tablet).
It can be taken with or without food.
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 Department at the nearest hospital if you think you or anyone else may have taken too many LAMITAN tablets. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much LAMITAN you may be more likely to have serious side effects which may be fatal.
Symptoms of overdose can include rapid, uncontrollable eye movements, clumsiness and lack of coordination affecting your balance, impaired or loss of consciousness, fits or coma.
While you are taking it
Things you must do
Contact your doctor immediately if you develop any skin rash, like spots or hives, during LAMITAN treatment. There are reports of skin rash associated with LAMITAN that may need hospital treatment or drug withdrawal; rarely serious skin rash may cause death. LAMITAN should be discontinued at the first sign of rash unless the rash is clearly not drug related.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking LAMITAN.
Tell your doctor or pharmacist that you are taking LAMITAN before starting any new medicine.
If you require a laboratory test, tell your doctor or hospital that you are taking LAMITAN. It may interfere with some laboratory tests to detect other drugs.
Tell your doctor immediately if you become pregnant or if you are planning to become pregnant. Your doctor will discuss the risks and benefits of taking this medicine during pregnancy.
Talk to your doctor if you are breast feeding or planning to breast feed. Lamotrigine can pass into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breast feeding while you are taking it.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise, your doctor may think that it is not working as it should and change your dosage unnecessarily.
Things you must not do
Do not stop taking LAMITAN, even if you feel better, or change the dose without first checking with your doctor. Stopping this medicine suddenly may cause your epilepsy to come back or be worse. This is known as “rebound seizures”.
Your doctor will advise you if you need to stop taking LAMITAN and how to do it gradually over about 2 weeks.
Do not give this medicine to anyone else even if their symptoms seem similar to yours.
Do not take it to treat any other complaints unless your doctor says to.
Do not take a double dose to make up for any that you may have missed.
Things to be careful of
Be careful driving or operating machinery until you know how LAMITAN affects you. As with other anti-epileptic medicines, LAMITAN may cause drowsiness or dizziness and affect alertness in some people, especially after the first dose. Make sure you know how you react to it 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. If you drink alcohol, dizziness or light-headedness may be worse.
Children should not ride a bike, climb trees or do anything else that could be dangerous if they are feeling dizzy or sleepy.
Tell your doctor immediately or go to the Accident and Emergency department of your nearest hospital if you or someone you know has any suicidal thoughts or other mental/mood changes. All mentions of suicide or violence must be taken seriously. Families and caregivers of children and adolescents who are taking LAMITAN should be especially watchful for any changing behaviour.
Anti-epileptic medicines such as LAMITAN may increase the risk of suicidal behaviour (including suicidal thoughts and suicide attempts).
Tell your doctor as soon as possible if you do not feel well while you are taking LAMITAN.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Potentially serious skin reaction
A small number of people taking LAMITAN 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 LAMITAN especially if the dose is too high or if the dose is increased too quickly, or if it 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, e.g. 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.
Liver and blood problems
Tell your doctor if you notice any of these symptoms:
- abdominal pain or tenderness
- feeling very tired
- easy bruising or unusual bleeding
- a sore throat, or more infections such as a cold, than usual
- yellow skin (jaundice).
Your doctor may decide to carry out tests on your liver, kidneys or blood and may tell you to stop taking LAMITAN if you experience these rare symptoms.
Tell your doctor as soon as possible if your seizures get worse or if you have a new type of seizure. You may need urgent medical attention or hospitalisation. Serious side effects are rare.
Tell your doctor if you notice anything else that is making you feel unwell, even if you think the problems are not connected with this medicine and are not referred to in this leaflet. Other side effects not listed above may also occur in some people.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
After taking it
Keep your tablets in a cool dry place, protected from light and moisture, where the temperature stays below 25°C.
