Lamictal belongs to a group of medicines called anti-epileptics. It is used to treat two conditions - epilepsy and bipolar disorder.
Lamictal treats epilepsy by blocking the signals in the brain that trigger epileptic seizures (fits)
■ For adults and children aged 13 years and over, Lamictal can be used on its own or with other medicines, to treat epilepsy. Lamictal 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, Lamictal 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.
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, Lamictal 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 Lamictal works in the brain to have this effect.
■ if you are allergic (hypersensitive) to lamotrigine or any of the other ingredients of this medicine (listed in Section 6).
If this applies to you:
^ Tell your doctor and don't take Lamictal.
Talk to your doctor or pharmacist before taking Lamictal:
■ if you have any kidney problems
■ if you have ever developed a rash after taking lamotrigine or other medicines for bipolar disorder or 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 the dose or that Lamictal is not suitable for you.
A small number of people taking Lamictal get an allergic reaction or potentially life-threatening skin reaction, which may develop into more serious problems if they are not treated. These can include Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN) and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). You need to know the symptoms to look out for while you are taking Lamictal.
^ Read the description of these symptoms in Section 4 of this leaflet under
Potentially life-threatening reactions: get a doctor’s help straight away’.
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 Lamictal:
^ 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 Lamictal have also had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
The seizures in some types of epilepsy may occasionally become worse or happen more often while you're taking Lamictal. 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 Lamictal:
^ See a doctor as soon as possible.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines including herbal medicines or other medicines bought without a prescription.
Your doctor needs to know if you are taking other medicines to treat epilepsy or mental health problems. This is to make sure you take the correct dose of Lamictal. These medicines include:
■ oxcarbazepine, felbamate, gabapentin, levetiracetam, pregabalin, topiramate or zonisamide, used to treat epilepsy
■ lithium, olanzapine or aripiprazole 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 Lamictal or make it more likely that people will 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
■ risperidone, used to treat mental health problems
■ rifampicin, which is an antibiotic
■ medicines used to treat Human Immunodeficiency Virus (HIV) infection (a
combination of lopinavir and ritonavir or atazanavir and ritonavir)
■ hormonal contraceptives, such as the Pill (see below).
^ Tell your doctor if you are taking any of these or if you start or stop taking any.
Your doctor may recommend that you use a particular type of hormonal contraceptive or another method of contraception, such as condoms, a cap or coil. If you are using a hormonal contraceptive like the Pill, your doctor may take samples of your blood to check the level of Lamictal. If you are using a hormonal contraceptive or if you plan to start using one:
^ Talk to your doctor, who will discuss suitable methods of contraception with you.
Lamictal 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 Lamictal is affecting the way your contraceptive is working.
There may be an increased risk of birth defects in babies whose mothers took Lamictal 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 Lamictal, so you may need blood tests and your dose of Lamictal may be adjusted.
^ If you are pregnant, think you may be pregnant or are planning to have a baby ask your doctor or pharmacist for advice before taking this medicine. You should not stop treatment without discussing this with your doctor. This is particularly important if you have epilepsy.
^ If you are breast-feeding or planning to breast-feed ask your doctor or pharmacist for advice before taking this medicine. The active ingredient of Lamictal passes into breast milk and may affect your baby. Your doctor will discuss the risks and benefits of breast-feeding while you're taking Lamictal and will check your baby from time to time if you decide to breast-feed.
Lamictal can cause dizziness and double vision.
^ Don’t drive or use machines unless you are sure you’re not affected.
Check with your doctor or pharmacist if you are not sure.
It may take a while to find the best dose of Lamictal for you. The dose you take will depend on:
■ your age
■ whether you are taking Lamictal with other medicines
■ whether you have any kidney or liver problems.
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 (called the effective dose). Never take more Lamictal than your doctor tells you to.
The usual effective dose of Lamictal for adults and children aged 13 years or over 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 maintenance dose of 200 mg daily.
Lamictal is not recommended for children aged under 2 years.
Take your dose of Lamictal once or twice a day, as your doctor advises. It can be taken 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.
Lamictal dispersible/chewable tablets can either be swallowed whole with a little water, chewed or mixed with water to make a liquid medicine.
You may need to drink a little water at the same time to help the tablet dissolve in the mouth. Then drink some more water to make sure all the medicine has been swallowed.
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 until the tablet is fully dissolved.
■ Drink all the liquid.
■ Add a little more water to the glass and drink that, to make sure no medicine is left in the glass.
If you take more Lamictal than you should
^ Contact a doctor or nearest hospital emergency department immediately. If
possible, show them the Lamictal packet.
If you take too much Lamictal you may be more likely to have serious side effects which may be fatal.
Someone who has taken too much Lamictal may have any of these symptoms:
■ rapid, uncontrollable eye movements (nystagmus)
■ clumsiness and lack of co-ordination, affecting their balance (ataxia)
■ heart rhythm changes (detected usually on ECG)
■ loss of consciousness, fits (convulsions) or coma.
If you forget to take Lamictal
Don’t take extra tablets to make up for a missed dose. Just take your next dose at the usual time.
^ Ask your doctor for advice on how to start taking it again. It's important that you do this.
Lamictal must be taken for as long as your doctor recommends. Don't stop unless your doctor advises you to.
To stop taking Lamictal, it is important that the dose is reduced gradually, over about 2 weeks. If you suddenly stop taking Lamictal, your epilepsy may come back or get worse.
Lamictal may take some time to work, so you are unlikely to feel better straight away. If you stop taking Lamictal, your dose will not need to be reduced gradually but you should still talk to your doctor first, if you want to stop taking Lamictal.
Like all medicines, this medicine can cause side effects, but not everyone gets them.
A small number of people taking Lamictal get an allergic reaction or potentially life-threatening skin reaction, which may develop into more serious problems if they are not treated.
These symptoms are more likely to happen during the first few months of treatment with Lamictal, especially if the starting dose is too high or if the dose is increased too quickly or if Lamictal is taken with another medicine called valproate. Some of the symptoms are more common in children, so parents should be especially careful to watch out for them.
Symptoms of these reactions include:
■ skin rashes or redness, which may develop into life-threatening 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) or extended rashes with liver, blood and other body organs involvement (Drug Reaction with Eosinophilia and Systemic Symptoms which is also known as hypersensitivity syndrome)
■ ulcers in the mouth, throat, nose or genitals
■ a sore mouth or red or swollen eyes (conjunctivitis)
■ 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 the fingers turning blue
■ a sore throat or more infections (such as colds) than usual
■ Increased levels of liver enzymes seen in blood tests
■ an increase in a type of white blood cell (eosinophils)
■ enlarged lymph nodes
■ involvement of the organs of the body including liver and kidneys.
In many cases, these symptoms will be signs of less serious side effects but you must be aware that they are potentially life-threatening and can develop into more serious problems, such as organ failure, if they are not treated. If you notice any of these symptoms:
^ Contact a doctor immediately. Your doctor may decide to carry out tests on your liver, kidneys or blood and may tell you to stop taking Lamictal. In case you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis your doctor will tell you that you must never use lamotrigine again.
