6    Further Information


Lamotrigine belongs to a group of medicines called anti-epileptics. It is used to treat two conditions — epilepsy and bipolar disorder.

Lamotrigine treats epilepsy by blocking the signals in the brain that trigger epileptic seizures (fits).

•    For adults and children aged 13 years and over, Lamotrigine can be used on its own or with other medicines, to treat epilepsy. Lamotrigine can also be used with other medicines to treat the seizures that occur with a condition called Lennox-Gastaut syndrome.

•    For children aged between 2 and 12 years, Lamotrigine can be used with other medicines, to treat those conditions. It can be used on its own to treat a type of epilepsy called typical absence seizures.

Lamotrigine also treats bipolar disorder.

People with bipolar disorder (sometimes called manic depression) have extreme mood swings, with periods of mania (excitement or euphoria) alternating with periods of depression (deep sadness or despair). For adults aged 18 years and over, Lamotrigine can be used on its own or with other medicines, to prevent the periods of depression that occur in bipolar disorder. It is not yet known how Lamotrigine works in the brain to have this effect.

2.    BEFORE YOU TAKE LAMOTRIGINE Do not take Lamotrigine:

•    if you are allergic (hypersensitive) to lamotrigine or any of the other ingredients of Lamotrigine (listed in Section 6). If this applies to you:

Tell your doctor, and don't take Lamotrigine.

Take special care with Lamotrigine

Your doctor needs to know before you take Lamotrigine:

•    if you have problems with your kidneys

•    if you have ever developed a rash when you've taken lamotrigine or other medicines for epilepsy

•    if you have ever developed meningitis after taking lamotrigine (read the description of these symptoms in Section 4 of this leaflet: Other side effects)

•    if you are already taking medicine that contains lamotrigine.

If any of these applies to you:

Tell your doctor, who may decide to lower your dose or that Lamotrigine, is not suitable for you.

Watch out for important symptoms

If you develop any of these symptoms after you start taking Lamotrigine, get a doctor’s help straight away:

   an unusual skin reaction, such as redness or rashes

•    a sore mouth or eyes

•    a high temperature (fever), flu-like symptoms or drowsiness

   swelling around your face, or swollen glands in your neck, armpit or groin

   unexpected bleeding or bruising, or your fingers turning blue

•    a sore throat or more infections (such as colds) than usual.

These symptoms are more likely to happen during the first few months of treatment with Lamotrigine, especially if you start on too high a dose or if your dose is increased too quickly, or if you're taking Lamotrigine with another medicine called valproate. Children are more likely to be affected than adults.

The symptoms listed above can develop into more serious problems, such as organ failure or a very severe skin condition, if they are not treated. If you notice any of these symptoms:

See a doctor as soon as possible. Your doctor may decide to carry out tests on your liver, kidneys or blood, and may tell you to stop taking Lamotrigine.

Thoughts of harming yourself or suicide

Anti epileptic medicines are used to treat several conditions, including epilepsy and bipolar disorder. People with bipolar disorder can sometimes have thoughts of harming themselves or committing suicide. If you have bipolar disorder, you may be more likely to think like this:

•    when you first start treatment

•    if you have previously had thoughts about harming yourself or about suicide

•    if you are under 25 years old.

If you have distressing thoughts or experiences, or if you notice that you feel worse or develop new symptoms while you're taking Lamotrigine:

See a doctor as soon as possible or go to the nearest hospital for help.

A small number of people being treated with anti epileptics such as Lamotrigine have also had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.

If you’re taking Lamotriginefor epilepsy

The seizures in some types of epilepsy may occasionally become worse or happen more often while you're taking Lamotrigine. Some patients may experience severe seizures, which may cause serious health problems. If your seizures happen more often, or if you experience a severe seizure while you're taking Lamotrigine:

See a doctor as soon as possible.

Lamotrigine should not be given to people aged under 18 years to treat bipolar disorder. Medicines to treat depression and other mental health problems increase the risk of suicidal thoughts and behaviour in children and adolescents aged under 18 years.

Taking other medicines

Tell your doctor or pharmacist if you’re taking any other medicines, if you’ve taken any recently, or if you start taking new ones — these include herbal medicines or other medicines you bought without a prescription.

If you are taking certain medicines, your doctor may need to check the dose of Lamotrigine. These include:

•    oxcarbazepine, felbamate, gabapentin, levetiracetam, pregabalin, topiramate or zonisamide, used to treat epilepsy

•    lithium, used to treat mental health problems

•    bupropion, used to treat mental health problems or to stop smoking Tell your doctor if you are taking any of these.

Some medicines interact with Lamotrigine or make it more likely that you'll have side effects. These include: valproate, used to treat epilepsy and mental health problems carbamazepine, used to treat epilepsy and mental health problems phenytoin, primidone or phenobarbitone, used to treat epilepsy olanzapine, used to treat mental health problems risperidone, used to treat mental health problems rifampicin, which is an antibiotic

a combination of lopinavir and ritonavir, used to treat Human Immunodeficiency Virus (HIV) infection hormonal contraceptives, such as the Pill (see below).

Tell your doctor if you are taking, or if you start or stop taking, any of these.

Hormonal contraceptives (such as the Pill) can affect the way Lamotrigine works

Your doctor may recommend that you use a particular type of hormonal contraceptive, or another method of contraception, such as condoms, a cap or a coil. If you are using a hormonal contraceptive like the Pill, your doctor may take samples of your blood to check the level of Lamotrigine. If you plan to start using a hormonal contraceptive:

Talk to your doctor, who will discuss suitable methods of contraception with you.

Lamotrigine can also affect the way hormonal contraceptives work, although it's unlikely to make them less effective.

If you are using a hormonal contraceptive and you notice any changes in your menstrual pattern, such as breakthrough bleeding or spotting between periods:

Tell your doctor. These may be signs that Lamotrigine is affecting the way your contraceptive is working. Pregnancy and breast feeding

Talk to your doctor if you’re pregnant, if you might be pregnant, or if you’re planning to become pregnant.

You should not stop treatment for your epilepsy while you're pregnant. However, there is an increased risk of birth defects in babies whose mothers took Lamotrigine during pregnancy. These defects include cleft lip or cleft palate. Your doctor may advise you to take extra folic acid if you're planning to become pregnant and while you're pregnant.

Pregnancy may also alter the effectiveness of Lamotrigine, so your doctor may take samples of your blood to check the level of Lamotrigine, and may adjust your dose.

—> Talk to your doctor if you’re breast feeding or planning to breast feed. The active ingredient of Lamotrigine passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breast feeding while you're taking Lamotrigine, and will check your baby from time to time if you decide to breast feed.

Driving and using machines

Lamotrigine can cause dizziness and double vision.

—> Don’t drive or operate machines unless you are sure you’re not affected.

If you have epilepsy, talk to your doctor about driving and using machines.


Always use Lamotrigine exactly as your doctor has told you to. Check with your doctor or pharmacist if you're not sure.

How much Lamotrigine to take

It may take a while to find the best dose of Lamotrigine for you. The dose you take will depend on:

•    your age

•    whether you are taking Lamotrigine with other medicines

•    whether you have problems with your kidneys or liver.

Your doctor will start you on a low dose, and gradually increase the dose over a few weeks until you reach a dose that works for you (called the effective dose). Never take more Lamotrigine than your doctor tells you to.

The usual effective dose of Lamotrigine for adults and children aged over 12 years is between 100 mg and 400 mg each day.

For children aged 2 to 12 years, the effective dose depends on their body weight — usually, it's between 1 mg and 15 mg for each kilogram of the child's weight, up to a maximum of 400 mg daily.

How to take your dose of Lamotrigine

Dispersible/chewable tablets:

Take your dose of Lamotrigine once or twice a day, as your doctor advises. You can take it with or without food. Always take the full dose that your doctor has prescribed. Never take only part of a tablet.

Your doctor may also advise you to start or stop taking other medicines, depending on what condition you're being treated for and the way you respond to treatment.

You can take Lamotrigine dispersible/chewable tablets by swallowing them whole with a little water, by chewing them, or by dissolving them in water:

If you chew the tablet:

You may need to drink a little water at the same time to help the tablet dissolve in your mouth. Then drink some more water to make sure you have swallowed all the medicine.

To make a liquid medicine:

Put the tablet in a glass with at least enough water to cover the whole tablet.

Either stir to dissolve, or wait for about a minute, until the tablet is fully dissolved.

Drink all the liquid.

Add a little more water to the glass and drink that, to make sure you've taken all the medicine.

If you take more Lamotrigine than you should

If anyone takes too much Lamotrigine:

-4 Contact a doctor or pharmacist immediately. If possible, show them the Lamotriginepacket.

Someone who has taken too much Lamotrigine may have any of these symptoms:

•    rapid, uncontrollable eye movements (nystagmus)

•    clumsiness and lack of co-ordination, affecting their balance (ataxia)

•    loss of consciousness or coma.

If you forget to take Lamotrigine

Don’t take extra tablets or a double dose to make up for a forgotten dose.

If you have missed taking a dose of Lamotrigine:

-4 Ask your doctor for advice on how to start taking it again. It's important that you do this.

Don’t stop taking Lamotrigine without advice

Take Lamotriginefor as long as your doctor recommends. Don't stop unless your doctor advises you to.

If you are taking Lamotrigine for epilepsy

To stop taking Lamotrigine, it is important that your dose is reduced gradually, over about 2 weeks. If you suddenly stop taking Lamotrigine, your epilepsy may come back or get worse.

If you are taking Lamotrigine for bipolar disorder

Lamotrigine may take some time to work, so you are unlikely to feel better straight away. If you stop taking Lamotrigine, your dose will not need to be reduced gradually. But you should still talk to your doctor first, if you want to stop taking Lamotrigine.


Like all medicines, Lamotrigine can cause side effects, but not everyone gets them.

Allergic reaction or potentially serious skin reaction: get a doctor’s help straight away

•    skin rashes or redness, which may develop into severe skin reactions including widespread rash with blisters and peeling skin, particularly occurring around the mouth, nose, eyes and genitals (Stevens-Johnson syndrome), extensive peeling of the skin (more than 30% of the body surface - toxic epidermal necrolysis)

•    a sore mouth or eyes

•    a high temperature (fever), flu-like symptoms or drowsiness

   swelling around your face, or swollen glands in your neck, armpit or groin

   unexpected bleeding or bruising, or your fingers turning blue

•    a sore throat, or more infections (such as colds) than usual.

In many cases, these symptoms will be signs of less serious side effects. But you must be aware that they are potentially serious — so, if you notice any of these symptoms:

See a doctor as soon as possible. Your doctor may decide to carry out tests on your liver, kidneys or blood, and may tell you to stop taking Lamotrigine.
