Lamotrigine Milpharm belongs to a group of medicines called anti-epileptics. It is used to treat two conditions – epilepsy and bipolar disorder.
Lamotrigine Milpharm treats epilepsy by blocking the signals in the brain that trigger epileptic seizures (fits).
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 Milpharm 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 Milpharm works in the brain to have this effect.

If this applies to you:
Take special care with Lamotrigine
Talk to your doctor or pharmacist before taking Lamotrigine
If any of these applies to you:
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).
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-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 lamotrigine. This risk may be associated with a variant in genes in people from Asian origin (mainly Han Chinese and Thai). If you are of such origin and have been tested previously carrying this genetic variant (HLA-B* 1502), discuss this with your doctor before taking lamotrigine.
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:
If you have distressing thoughts or experiences, or if you notice that you feel worse or develop new symptoms while you’re taking Lamotrigine:
A small number of people being treated with anti-epileptics such as Lamotrigine Milpharm 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 Lamotrigine Milpharm. 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 Milpharm:
Lamotrigine Milpharm 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.
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 breast-feeding).
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. These medicines include:
Some medicines interact with Lamotrigine Milpharm or make it more likely that people will have side effects. These include:
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 Milpharm. If you are using a hormonal contraceptive, or if you plan to start using one:
Lamotrigine Milpharm 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:
Lamotrigine Milpharm can cause dizziness and double vision.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
Lamotrigine Milpharm 100 mg tablets contain sunset yellow aluminium lake, which may cause allergic reactions.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium free’.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you’re not sure.
It may take a while to find the best dose of Lamotrigine Milpharm for you. The dose you take will depend on:
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 Milpharm than your doctor tells you to.
The recommended effective dose of Lamotrigine Milpharm 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 is not recommended for children aged under 2 years.
Take your dose of Lamotrigine Milpharm 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.
Use a tablet cutter to halve tablets. Alternatively, keeping the score-line side facing upwards, hold both the upper and lower sides of the tablet, on either side of the score-line, using the thumb and index finger of both hands [fig. A] and halve the tablet by pressing down and away from the score-line so that the tablet opens at the score-line side [fig. B]. Do not hold on to the shoulder (end) of the tablet, on either side of the score-line [fig. C], when halving since this may cause the tablet to crumble.
If you take too much Lamotrigine you may be more likely to have serious side effects which may be fatal.
Someone who has taken too much Lamotrigine Milpharm may have any of these symptoms:
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
Don’t stop taking Lamotrigine Milpharm without advice
Lamotrigine Milpharm must be taken for as long as your doctor recommends. Don’t stop unless your doctor advises you to.
To stop taking Lamotrigine Milpharm, it is important that the dose is reduced gradually, over about 2 weeks. If you suddenly stop taking Lamotrigine Milpharm, your epilepsy may come back or get worse.
Lamotrigine Milpharm may take some time to work, so you are unlikely to feel better straight away. If you stop taking Lamotrigine Milpharm, 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 Milpharm.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
A small number of people taking Lamotrigine Milpharm 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, 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:
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:
Haemophagocytic lymphohistiocytosis (HLH) (see section 2: What you need to know before you take Lamotrigine)
Very common (may affect more than 1 in 10 people):
Common (may affect up to 1 in 10 people):
Uncommon (may affect up to 1 in 100 people):
Rare (may affect up to 1 in 1,000 people):
Very rare( may affect up to 1 in 10,000 people):
Other side effects have occurred in a small number of people but their exact frequency is unknown.
