Consumer Medicine Information


Please read this leaflet carefully before you take LAMOTRIGINE-PS tablets.

This leaflet answers some common questions about LAMOTRIGINE-PS. It does not contain all the available information.

It does not take the place of talking to your doctor and pharmacist.

All medicines have risks and benefits. Sometimes new risks are found even when a medicine has been used for many years. Your doctor has weighed the risks of you taking LAMOTRIGINE-PS against the benefits this medicine is expected to have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.


LAMOTRIGINE-PS contains the active ingredient lamotrigine and is an antiepileptic drug used to treat epilepsy in adults and children.

Epilepsy is caused by a disruption in the electrical activity of the brain.

The abnormal electrical impulses occur due to altered levels of some of the chemicals in the brain.

LAMOTRIGINE-PS tablets work by altering the levels of some of the chemicals causing the seizures.

LAMOTRIGINE-PS is used in partial seizures that affect only one part of the brain or generalised seizures that affect the whole brain including Lennox-Gastaut Syndrome.

Lennox-Gastaut Syndrome (LGS) is a severe form of epilepsy and is characterised by several seizure types.

LAMOTRIGINE-PS tablets are initially used in addition to other medicines for the treatment of epilepsy.

Your doctor may have prescribed LAMOTRIGINE-PS for another reason. Ask your doctor if you have any questions about why LAMOTRIGINE-PS has been prescribed for you.

This medicine is available only with a doctor’s prescription.

There is no evidence that LAMOTRIGINE-PS is addictive.


When you must not take it

Do not take LAMOTRIGINE-PS if:

  • You have an allergy to lamotrigine or any ingredients listed at the end of this leaflet.
    Some of the symptoms of an allergic reaction may include skin rash, itching, difficulty breathing, swelling of the face, lips or tongue.
  • The packaging is torn or shows signs of tampering.
  • The expiry date on the pack has passed.
    If you take this medicine after the expiry date has passed, it may not work as well (or it may make you feel sick).

If you are not sure whether you should start taking LAMOTRIGINE-PS, talk to your doctor.

Before you take it

You must tell your doctor:

  1. If you are allergic to any other medicines, foods, dyes or preservatives.
  2. If you have or have ever had any other health problems/ medical conditions, including:
  • kidney disease
  • liver disease
  1. If you are taking any other medicines.This is particularly important for sodium valproate (“Epilim”, “Valpro”) or if you are taking any form of hormonal contraceptive (e.g. “the pill”) or hormone replacement therapy, other anti-epileptic drugs (e.g. carbamazepine or phenobarbitone) or medicines you buy without a prescription.

These medicines may be affected by LAMOTRIGINE-PS or may affect how well it works. You may need different amounts of your medicine or you may need to take different medicines.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking LAMOTRIGINE-PS.

  1. If you are breastfeeding, pregnant or trying to become pregnant. It is recommended that women on antiepileptic drugs such as LAMOTRIGINE-PS receive pre-pregnancy counselling with regard to the risk to their unborn child.
    There is not enough information available on the use of LAMOTRIGINE-PS tablets during pregnancy to determine whether or not it is safe. LAMOTRIGINE-PS is thought to pass into breast milk.

Your doctor will discuss the risks and benefits of using LAMOTRIGINE-PS tablets if you are pregnant or breastfeeding, including the risk to mother and foetus of uncontrolled epilepsy, when deciding on treatment options.

Studies have shown a decrease in the levels of folic acid during pregnancy in women treated with LAMOTRIGINE-PS. It is therefore recommended that you take a folic acid supplement, e.g. 5 mg folic acid daily, before becoming pregnant and during the first 12 weeks of your pregnancy.

If you have not told your doctor about any of the above, tell them before you are given LAMOTRIGINE-PS.


Taking LAMOTRIGINE-PS for the first time

During the first few weeks of treatment, you may experience blurred vision, dizziness, tiredness or unsteadiness when you are walking.

As your reactions may be slower during this period, you should avoid operating any machinery and appliances and you should not drive a car. If any of these effects persist for a long period of time or prove to be troublesome, you should consult your doctor.

There have been reports of skin rash associated with treatment. Some of these rashes may be serious and can cause severe illness.

If you notice the development of any skin rash (e.g. hives or spots) during treatment, contact your doctor immediately.

If you have any questions about taking LAMOTRIGINE-PS tablets ask your doctor or pharmacist.

How much to take

Your doctor will determine your dose and how long you will receive LAMOTRIGINE-PS.

Take LAMOTRIGINE-PS tablets 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 your doctor or pharmacist.

It is usual for the dose of LAMOTRIGINE-PS tablets to start at quite a low level and be slowly increased during the first few weeks of treatment.

The dose prescribed by your doctor is dependent upon the other epileptic medications you are taking and your response to LAMOTRIGINE-PS.

Hormonal contraceptives: If you start or stop taking hormonal contraceptives (e.g. “the pill”) while taking LAMOTRIGINE-PS, your doctor may need to adjust the dose of LAMOTRIGINE-PS 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-PS during your pregnancy.

LAMOTRIGINE-PS for children is dependent upon their weight and changes to the dose must be made accordingly.

How long to take it for

Do not stop taking LAMOTRIGINE-PS tablets, or change the dose, without first checking with your doctor.

If you are about to start taking a new medicine, tell your doctor and pharmacist that you are taking LAMOTRIGINE-PS.

Do not take any other medicines whether they require a prescription or not without first telling your doctor.

If you develop any skin rash (e.g. hives or spots) while being treated with LAMOTRIGINE–GA, contact your doctor immediately. There are reports of serious skin rash with Lamotrigine that may need hospital treatment or drug withdrawal;rarely serious skin rash may cause death.

Tell your doctor if you become pregnant or are trying to become pregnant while taking LAMOTRIGINE-PS.

Things you must not do

Do not stop taking LAMOTRIGINE-PS or change the dose because you are feeling better. Consult your doctor first.

If you stop taking LAMOTRIGINE-PS tablets abruptly, your epilepsy may worsen or even come back. This is known as rebound seizures.

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

Do not use LAMOTRIGINE-PS to treat any other complaints unless your doctor tells you to.

Things to be careful of

Be careful driving or operating machinery until you know how LAMOTRIGINE-PS affects you.

LAMOTRIGINE-PS may cause dizziness and drowsiness and affect alertness in some individuals. If this occurs, avoid operating machinery, driving a car or doing anything that could be dangerous.

Make sure you know how you react to LAMOTRIGINE-PS 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 consuming alcohol, dizziness or light-headedness may be worse.

Children should avoid riding a bike, climbing trees or doing anything that could be dangerous if they are feeling dizzy or sleepy.


Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking LAMOTRIGINE-PS.

These side effects usually occur during the first few weeks of treatment. However, if any of these side effects persist, consult your doctor.

Caution is also required when treating patients with a history of allergy or rash to other antiepileptic drugs as the frequency of non-serious rash after treatment with lamotrigine was approximately three times higher in these patients than in those without such history.

Antiepileptics, such as LAMOTRIGINE-PS may increase the risk of suicidal thoughts and behaviour.

If you or someone you know is demonstrating any of the following warning signs, contact your doctor or a mental health professional right away or go to your nearest hospital for treatment:

  • Thoughts or talk of death or suicide
  • Thoughts or talk of self-harm or harm to others
  • Any recent attempts at self-harm

  • fever
  • any skin reactions (eg. rash or hives)
  • drowsiness
  • swollen glands
  • sore mouth or sore eyes
  • yellow skin (jaundice)
  • unusual bleeding and easy bruising
  • swelling of the face, lips or tongue

These are all serious side effects of LAMOTRIGINE-PS. You may need urgent medical attention.

Serious side effects are rare.

Another rare side effect is “Lupus-like reactions” which may present as a collection of symptoms consisting of fever, pain in the joints and general ill health.

If any of the following happens, stop using LAMOTRIGINE-PS and tell your doctor immediately or go to casualty at your nearest hospital:

  • Life threatening allergic reactions which may include lumpy rash (“hives”), fainting, itching, difficulty breathing, swelling of the face, lips or tongue.

These are all very serious side effects of LAMOTRIGINE-PS. If you have them, you may have had a serious allergic reaction to LAMOTRIGINE-PS. You may need urgent medical attention or hospitalisation.

If you are female, tell your doctor if your menstrual periods change.

Other side effects not listed above may also occur in some patients. Tell your doctor if you notice any other effects.

Ask your doctor or pharmacist if you don’t understand anything in this list.

Do not be alarmed by this list of possible side effects. You may not experience any of them.



Keep your LAMOTRIGINE-PS tablets in their original pack until it is time to take them. If you take the tablets out of the pack, they may not keep well.

Keep the pack in a cool, dry place where the temperature stays below 25° C and away from light.

Do not store it or any other medicine in the bathroom or near a sink. Do not leave it in the car or on window sills. Heat and dampness can destroy some medicines.

Keep it 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.
