1. WHAT LAMOTRIGINE TORRENT TABLETS ARE AND WHAT THEY ARE USED FOR

Lamotrigine tablets belong to a group of medicines called anti-epileptics. They are used to treat two conditions – epilepsy and bipolar disorder.

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

For adults and children aged 13 years and over, Lamotrigine tablets can be used on its own or with other medicines, to treat epilepsy. Lamotrigine tablets 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 tablets can be used with other medicines, to treat those conditions. They can be used on their own to treat a type of epilepsy called typical absence seizures.

Lamotrigine tablets also treat 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 tablets can be used on their own or with other medicines, to prevent the periods of depression that occur in bipolar disorder. It is not yet known how Lamotrigine tablets work in the brain to have this effect.

2. what you need to know before you take lamotrigine torrent tablets

Do not take Lamotrigine Torrent tablets:

if you are allergic to lamotrigine or any of the other ingredients of this medicine (listed in Section 6).

if you have any kidney problems
if you have ever developed a rash after taking lamotrigine or other medicines for bipolar disorder or epilepsy; or if you experience a rash or sunburn after taking lamotrigine 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 ever developed meningitis after taking lamotrigine (read the description of these symptoms in Section 4 of this leaflet: Rare side effects)
if you are already taking medicine that contains lamotrigine.

Important information about potentially life-threatening reactions

A small number of people taking Lamotrigine tablets get an allergic reaction or potentially life-threatening skin eaction, which may develop into a 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 Syndrome (DRESS). You need to know the symptoms to look out for while you are taking Lamotrigine tablets.

■ + Read the description of these symptoms in Section 4 of this leaflet under ‘Potentially life-threatening reactions: get a doctor’s help straight away’.

Haemophagocytic lymphohistiocytosis (HLH)

There have been reports of a rare but very serious immune system reaction, in patients taking lamotrigine.

■ + Contact your doctor or pharmacist immediately if you experience any of the following symptoms while taking lamotrigine: fever, rash, neurological symptoms (e.g. shaking or tremor, confusional state, disturbances of brain function).

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 tablets:

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

You may find it helpful to tell a family member, caregiver or close friend that you can become depressed or have significant changes in mood, and ask them to read this leaflet. You might ask them to tell you if they are worried about your depression or other changes in your behaviour.

A small number of people being treated with anti-epileptics such as Lamotrigine tablets 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 Lamotrigine Torrent tablets for epilepsy

The seizures in some types of epilepsy may occasionally become worse or happen more often while you’re taking Lamotrigine tablets. 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 tablets:

■+ See a doctor as soon as possible.

Lamotrigine tablets 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.

Other medicines and Lamotrigine tablets

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. It is important to tell your doctor or pharmacist if you are taking any other medicines for epilepsy at the same time as lamotrigine if you are pregnant, think you may be pregnant, or are planning to have a baby (see also the information in Section 2 on pregnancy and breastfeeding).

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 Lamotrigine tablets.

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 Lamotrigine tablets 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.

Hormonal contraceptives (such as the Pill) can affect the way Lamotrigine Torrent tablets work 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 Lamotrigine. 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.

Lamotrigine tablets 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 tablets are affecting the way your contraceptive is working.

Pregnancy and breast-feeding

■ + If you are pregnant, think you may be pregnant, you must tell your doctor straight away and discuss possible risks the epilepsy medicine you are taking might pose to your unborn baby.
■ + If you are planning to become pregnant you should discuss your epilepsy treatment with your doctor as early as possible before you become pregnant.

You should not stop treatment without discussing this with your doctor. This is particularly important if you have epilepsy.
Pregnancy may alter the effectiveness of Lamotrigine tablets, so you may need blood tests and your dose of Lamotrigine tablets may be adjusted.
Studies of women who took lamotrigine at usual doses while they were pregnant have not shown an increased risk of physical birth abnormalities.
The risk of physical birth abnormalities may increase when higher doses of epilepsy medicines are taken or more than one epilepsy medicine is used at the same time. Where possible, your doctor will consider using one epilepsy medicine at the lowest effective dose to control your epilepsy.
Your doctor may advise you to take extra folic acid supplements if you’re planning to become pregnant and while you’re pregnant.
■+ 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 Lamotrigine tablets 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 tablets and will check your baby from time to time, whether drowsiness, rash or poor weight gain occurs, if you decide to breast-feed. Inform your doctor if you observe any of these symptoms in your baby.

Driving and using machines

Lamotrigine tablets 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.

| 3. HOW TO TAKE LAMOTRIGINE TORRENT TABLETS

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

How much Lamotrigine Torrent tablets to take

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

your age
whether you are taking Lamotrigine tablets 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 Lamotrigine tablets than your doctor tells you to.

The usual effective dose of Lamotrigine tablets 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.

Lamotrigine tablets are not recommended for children aged under 2 years.

How to take your dose of Lamotrigine Torrent tablets

Take your dose of Lamotrigine tablets once or twice a day, as your doctor advises. It can be taken with or without food.

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.

Swallow your tablets whole. Don’t break, chew or crush them.
Always take the full dose that your doctor has prescribed. Never take only part of a tablet.

If you take more Lamotrigine Torrent tablets than you should

■+ Contact a doctor or nearest hospital emergency department immediately. If possible, show them the Lamotrigine tablets packet.

----- If you take too much Lamotrigine Torrent tablets you may be more likely to have serious side effects which may be fatal.

Someone who has taken too much Lamotrigine tablets 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 a single dose of Lamotrigine Torrent tablets

■+ Don’t take extra tablets to make up for a missed dose. Just take your next dose at the usual time.

In case you forget to take multiple doses of Lamotrigine Torrent tablets

■+ Ask your doctor for advice on how to start taking it again. It’s important that you do this.

Don’t stop taking Lamotrigine tablets without advice

Lamotrigine tablets must be taken for as long as your doctor recommends. Don’t stop unless your doctor advises you to.

If you’re taking Lamotrigine Torrent tablets for epilepsy

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

If you are taking Lamotrigine Torrent tablets for bipolar disorder

Lamotrigine tablets may take some time to work, so you are unlikely to feel better straight away. If you stop taking Lamotrigine tablets, 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 tablets.

4. POSSIBLE SIDE EFFECTS

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

Potentially life-threatening reactions: get a doctor’s help straight away

A small number of people taking Lamotrigine tablets 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 Lamotrigine tablets, especially if the starting dose is too high or if the dose is increased too quickly or if Lamotrigine tablets are 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 DRESS 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 Lamotrigine tablets. In case you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis your doctor will tell you that you must never use lamotrigine again.
