LAMOTRIGINE RUDIPHARM 25 MG TABLETS - patient leaflet, side effects, dosage

1. what lamotrigine is and what it is used for

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

Lamotrigine treat 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 their 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 the same conditions as above. They can be used on their own to treat a type of epilepsy called typical absence seizures.

Lamotrigine 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 can be used alone or with other medicines to prevent the periods of depression that occur in bipolar disorder. It is not yet known how Lamotrigine work in the brain to have this effect.

2. what you need to know before you take lamotrigine do not take lamotrigine

• if you are allergic (hypersensitive) to lamotrigine or any of the other ingredients of this medicine (listen in section 6).

If this applies to you tell your doctor and don’t take Lamotrigine.

Warnings and precautions

Talk to your doctor or pharmacist before taking Lamotrigine:

• if you have any kidney problems
• if you have ever developed a rash after taking Lamotrigine Tablets or other medicines for bipolar disorder or epilepsy
• 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 are already taking a medicine that contains Lamotrigine
• 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 have a condition called Brugada syndrome.

Brugada syndrome is a generic disease that results in abnormal electrical activity within the heart. ECG abnormalities which may lead to arrhythmias (abnormal heart rhythm) can be triggered by 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.

Important information about potentially life-threatening reactions

A small number of people taking Lamotrigine 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-Johnsons 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 Lamotrigine.

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 lymphohistocytosis (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:

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 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 for epilepsy

The seizures in some types of epilepsy may occasionally become worse or happen more often while 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.

Other medicines and Lamotrigine

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 to treat for epilepsy
• lithium, olanzapine or aripiprazole used to treat mental health problems
• bupropion used to treat mental health problems or to stop smoking

Some medicines interact with Lamotrigine 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 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 are affecting the way your contraceptive is working.

Pregnancy and breast-feeding

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.
• Pregnancy may alter the effectiveness of Lamotrigine, so you may need blood tests and your dose of Lamotrigine may be adjusted.
• There may be a small increased risk of birth defects, including a cleft lip or cleft palate if Lamotrigine is taken during the first 3 months of pregnancy.
• Your doctor may advise you to take extra folic acid 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.

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, 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 can cause dizziness and double vision.

Do not drive or operate machines unless you are sure you are not affected.

Lamotrigine contains Mannitol

You may experience of mild laxative effect.

3. how to take lamotrigine

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 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 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 recommended dose is:

For adults and children aged over 13 years:

The usual effective dose of Lamotrigine 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 1mg and 15mg for each kilogram of the child’s weight, up to a maximum maintenance dose of 200 mg daily. Lamotrigine is not recommended for children aged under 2 years.

How to take your dose of Lamotrigine

Take your dose of Lamotrigine once or twice a day, as your doctor advises. You can take it 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.

The score line is only there to help you break the tablet if you have difficulty swallowing it whole.

If you take more Lamotrigine than you should

If anyone takes too many Lamotrigine, contact a doctor or pharmacist immediately. If possible, show them the Lamotrigine packet.

If you take too many Lamotrigine Tablets you may be more likely to have serious side effects which may be fatal.

Someone who has taken too many 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 Lamotrigine:

Do not take a double dose to make up for a forgotten dose. If you have missed taking a dose of Lamotrigine: Ask your doctor for advice on how to start taking it again.

Don’t stop taking Lamotrigine without advice

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

If you’re 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’re 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.

4. possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

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

A small number of people taking Lamotrigine have 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, especially if the starting dose is too high or if the dose is increased too quickly or if Lamotrigine 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 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 of the 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
• increased levels of liver enzymes seen in blood tests
• an increase in a type of white blood cell (eosinophilia)
• 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 your doctor immediately.

Your doctor may carry out tests on your liver, kidneys or blood and may tell you to stop taking Lamotrigine. In case you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis your doctor will tell you that you must never use Lamotrigine again.
