Consumer Medicine Information
THERE ARE REPORTS OF SEVERE, POTENTIALLY LIFE THREATENING RASHES ASSOCIATED WITH LOGEM
TREATMENT, PARTICULARLY IN CHILDREN. LOGEM 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 LOGEM. It does not contain all the
available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking
LOGEM 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 the medicine.
You may need to read it again.
What LOGEM is used for
LOGEM contains lamotrigine as the active ingredient and belongs to a group of medicines
called "anti-epileptic drugs".
Anti-epileptic drugs, such as LOGEM, are used to treat epilepsy in adults and children
aged 2 years and older. Epilepsy is a condition where you have repeated seizures (fits).
Initially, LOGEM is usually used in addition to other medicines for the treatment
of epilepsy including partial or generalised seizures and Lennox-Gastaut Syndrome.
It is thought that this medicine works by changing the levels of some chemicals associated
with seizures.
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 only available with a doctor's prescription.
This medicine is not addictive.
Before you take LOGEM
When you must not take it
Do not take LOGEM if you have an allergy to:
any medicine containing lamotrigine
any of the ingredients listed at the end of this leaflet
Symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty in breathing
swelling of the face, lips, tongue or any other parts of the body
rash, itching or hives on the skin
Do not take this medicine after the expiry date printed on the pack or if the packaging
is torn or shows signs of tampering.
If it has expired or is damage, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Before you start to take it
Tell your doctor if you have allergies to any other medicines, foods, preservatives
or dyes.
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
Tell your doctor if you are pregnant or plan to become pregnant.
LOGEM may affect your unborn baby if you take it during pregnancy but it is still
important that you control your fits whilst you are pregnant. Your doctor will discuss
the risks and benefits of taking this medicine during pregnancy.
It is recommended that women on anti-epileptic drugs, such as LOGEM, receive pre-pregnancy
counselling with regard to the possible risk to their unborn child.
Studies have shown a decrease in the levels of folic acid during pregnancy when LOGEM
is also used. It is therefore recommended that you take a daily 5 mg folate supplement
before becoming pregnant and during the first 12 weeks of your pregnancy.
Tell your doctor if you are breast feeding or planning to breast feed.
LOGEM 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 LOGEM.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any
that you get without a prescription from a pharmacy, supermarket or health food shop.
Some medicines may interfere with LOGEM. These include:
valproate and carbamazepine, used to treat both epilepsy and mental health problems
any form of hormonal medicine, e.g. "the pill" or HRT
other anti-epileptic drugs, e.g. phenytoin, primidone or phenobarbitone
OCT2 substrates such as dofetilide
rifampicin, an antibiotic, which is used to treat infections, including tuberculosis
medicines used to treat Human Immunodeficiency Virus (HIV) infection
risperidone, used to treat mental health problems
These medicines may be affected by LOGEM or may affect how well it works. You may
need different amounts of your medicines or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or
avoid while taking this medicine.
How to take LOGEM
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 box, ask your doctor or pharmacist
for help.
Using LOGEM for the first time
You may notice that you feel dizzy, tired or unsteady in the first few weeks of treatment
with LOGEM 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 drive a car. If any of these effects do not go away or are
troublesome you should see your doctor.
Tell your doctor immediately if you develop any skin rash such as spots or 'hives'
during LOGEM treatment.
There are reports of severe, potentially life-threatening rashes associated with LOGEM
treatment, particularly in children. LOGEM should be discontinued at the first sign
of rash unless the rash is clearly not drug related.
Contact your doctor if you experience a rash or sunburn after taking Lamictal and
having been exposed to sun or artificial light, e.g. solarium.
Your doctor will check your treatment and may advise you to avoid sunlight or protect
yourself against the sun, e.g. use of a sunscreen and/or to wear protective clothing.
If you have any questions about taking LOGEM ask your doctor or pharmacist.
How much to take
It may take a while to find the best dose of LOGEM for you.
The dose you take will depend on:
your age and weight
whether you are taking LOGEM with other medications
whether you have any kidney or liver problems
Never take more of this medicine than your doctor tells you to.
Do not increase the dose faster than you have been told.
Your doctor will prescribe a low dose to start 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 LOGEM. 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 LOGEM as "the pill" may not work as effectively
for contraception whilst taking it.
How to take it
LOGEM tablets may be swallowed whole, chewed or dispersed in sufficient water to cover
the whole tablet.
LOGEM can be taken with or without food.
Your doctor may also advise you to start or stop taking other medications, depending
on what condition you are being treated for and the way you respond to treatment.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
This medicine helps to control your condition, but does not cure it. It is important
to keep taking your medicine even if you feel well.
Do not stop taking LOGEM or change the dose without first checking with your doctor.
Your doctor will advise you if you need to stop taking LOGEM and how to do this gradually
over a period of two weeks.
Use in children
LOGEM is not recommended for treatment of epilepsy in children under 2 years of age.
Children's weight should be checked and the dose reviewed as weight changes with growth
occur.
If you forget to take it
If you have forgotten to take your dose of LOGEM contact your doctor immediately.
Do not take a double dose to make up for the dose 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 Accident and Emergency at the nearest hospital, if you
think that you or anyone else may have taken too much LOGEM. Do this even if there
are no signs of discomfort or poisoning.
If you take too much Lamictal you may be more likely to have serious side effects
which may be fatal.
You may need urgent medical attention.
Symptoms of LOGEM 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 LOGEM
Your doctor or pharmacist will be able to tell you whether there are any special instructions
while you are taking LOGEM tablets.
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist
that you are taking LOGEM.
Tell any other doctors, dentists and pharmacists who treat you that you are taking
this medicine, you are about to be started on any new medicines.
Take LOGEM exactly as your doctor has prescribed.
If you develop any skin rash (e.g. spots or 'hives') during LOGEM treatment contact
your doctor immediately.
There are reports of severe, potentially life-threatening rashes associated with LOGEM
treatment, particularly in children. LOGEM should be discontinued at the first sign
of rash unless the rash is clearly not drug related.

enlarged/swollen lymph nodes whilst taking this medicine. If you are about to have
a blood test, tell your doctor or hospital that you are taking this medicine.
LOGEM may interfere with some laboratory tests to detect other drugs.
Talk to your doctor as soon as possible if you are pregnant or if you are planning
to become pregnant.
Your doctor will discuss the risks and benefits of taking LOGEM during pregnancy.
Talk to your doctor if you are breast feeding or planning to breast feed.

Otherwise, your doctor may think that it was not working as it should and change your
treatment unnecessarily.
Things you must not do

Do not give your medicine to anyone else, even if they have the same condition as
you.
Do not stop taking your medicine or change the dose without checking with your doctor.
Do not take a double dose to make up for any that you may have missed.
If you stop taking it suddenly your epilepsy may return or become worse. This is known
as "rebound seizures".
Your doctor will advise you if you need to stop taking LOGEM and how to do this gradually
over about 2 weeks.
Things to be careful of
Be careful driving or operating machinery until you know how LOGEM affects you.
As with other anticonvulsant medicines for the treatment of epilepsy, LOGEM may cause
dizziness and drowsiness in some people and affect alertness.
Make sure you know how you react to LOGEM 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.
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 LOGEM should be especially watchful for
any changes in behaviour. Anti-epileptic medicines such as LOGEM may increase the
risk of suicidal behaviour (including suicidal thoughts and suicide attempts).
Side effects
Tell your doctor or pharmacist as soon as possible if you do not feel well while you
are taking LOGEM.
This medicine helps most people with epilepsy, but it may have unwanted side effects
in a few people. All medicines can have side effects. Sometimes they are serious,
most of the time they are not. You may need medical treatment if you have some of
the side effects.
Do not be alarmed by the following list of side effects. You may not experience any
of them.
Ask your doctor or pharmacist to answer any questions you may have.
The most commonly reported side effects of LOGEM are:
dizziness
movement problems such as tics, unsteadiness and jerkiness
tremors
skin rash
headache
nausea
vomiting
feeling drowsy or tired
blurred or double vision
rapid, uncontrollable eye movements
trouble sleeping
feeling sleepy
irritability, aggression or agitation
hallucinations, confusion
increased activity in children
joint, back or stomach pain
respiratory or lung problems
depression
loss of memory
liver problems
diarrhoea
dry mouth
In general, these side effects usually happen during the first few weeks of treatment
with LOGEM.
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 whilst taking LOGEM.
All mentions of suicide or violence must be taken seriously. Families and caregivers
of children and adolescents who are taking LOGEM should be especially watchful for
any changing behaviour. Anti-epileptic medicines such as LOGEM may increase the risk
of suicidal behaviour (including suicidal thoughts and suicide attempts).
Potentially serious skin reaction
A small number of people taking LOGEM 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 LOGEM, especially if the dose is too high or if the dose is increased too quickly,
or if LOGEM is taken with another 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')
skin rash or sunburn after exposure to sun or artificial light (photosensitivity)wheezing,
difficulty in breathing
swelling of the face, lips or tongue
sore mouth or sore eyes
fever
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:
drowsiness
itching
abdominal pain or tenderness
feeling very tired
unusual bleeding or bruising more easily than normal
a sore throat or more infections, such as a cold, than usual
yellowing of the skin (jaundice)
Your doctor may decide to carry out tests on your liver, kidneys or blood and may
tell you to stop taking LOGEM if you experience these rare symptoms.
Potentially serious aseptic meningitis
LOGEM increases the risk of meningitis, which is a serious inflammation of the protective
membrane that covers the brain and spinal cord.
Many of the side effects already listed are symptoms of this condition, as well as
light sensitivity, stiff neck, muscle pains and chills.
Potentially serious / life threatening arrhythmia
If you have had a fast heartbeat, heart failure, or other heart problems, you should
not take lamotrigine. This drug may cause you to have an abnormal heartbeat, which
could lead to sudden death. Symptoms include a fast, slow, or pounding heartbeat,
shortness of breath, chest pain, and feeling lightheaded.
Tell your doctor if you notice any of these 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 or pharmacist if you notice anything 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 LOGEM
Storage
Keep your tablets in the pack until it is time to take them.
If you take the tablets out of the pack they will not keep well.

Keep LOGEM where children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place
to store medicines.
