Lamotrigine
Symla belongs to a group of medicines called antiepileptics. It is used to treat two diseases - epilepsy and bipolar affective disorders. The action of Symla in the treatment of epilepsyinvolves blocking impulses in the brain that cause epileptic seizures.
In patients with bipolar affective disorders (sometimes called manic-depressive psychosis), there are extreme mood swings with episodes of mania (excitement or euphoria) alternating with episodes of depression (deep sadness or despair). In adults over 18 years of age, Symla can be used alone or in combination with other medicines to prevent depressive episodes in bipolar affective disorders. The mechanism by which Symla works in the brain to produce this effect is not yet known.
In such a case:
➢ Tell your doctorand do not take Symla.
Before starting to take Symla, discuss with your doctor or pharmacist if:
In case of any of the above:
➢ Tell your doctor, who may decide to reduce the dose or decide that Symla is not a suitable medicine for the patient.
A small number of patients taking Symla may experience an allergic reaction or a potentially life-threatening skin reaction that can worsen if left untreated. Such reactions include Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS). The patient should be aware of the symptoms of these conditions and keep them in mind while taking Symla. This risk may be associated with a genetic variant found in people of Asian descent (mainly Chinese Han and Thai). If the patient is of such descent and has previously been found to have this genetic variant (HLA-B*1502), they should discuss this with their doctor before taking Symla.
➢ Read the description of these symptoms in section 4 of this leaflet, in the section “Life-threatening reactions: seek medical attention immediately”.
In patients taking lamotrigine, cases of a rare but very serious reaction of the immune system have been reported.
➢ If the patient experiences any of the following symptoms while taking lamotrigine: fever, rash, neurological symptoms (e.g. tremors or shivers, confusion, brain function disorders), seek medical attention immediately.
Antiepileptic medicines are used to treat various diseases, including epilepsy and bipolar affective disorders. In patients with bipolar affective disorders, thoughts of self-harm or suicide may sometimes occur. If the patient has bipolar affective disorders, such thoughts may occur more frequently:
➢ Seek medical attention immediately. It may be helpful to inform a relative, caregiver, or friend that the patient may experience depression or significant mood changes and ask them to read this leaflet. The patient may ask them to tell them if they notice that they are experiencing depression or worrying changes in behavior.
In a small number of patients treated with antiepileptic medicines, such as Symla, thoughts of self-harm or suicide have also occurred. If the patient has ever had such thoughts, they should tell their doctor immediately.
In some types of epilepsy, seizures may sometimes worsen or occur more frequently while taking Symla. In some patients, severe seizures may occur, which can pose a serious risk to the patient's health. If the patient experiences more frequent or severe seizures while taking Symla:
➢ Seek medical attention immediately.
In patients under 18 years of age. Medicines used to treat depression or other mental disorders increase the risk of suicidal thoughts or behaviors in children and adolescents under 18 years of age.
the patient is currently taking, or has recently taken, and about medicines the patient plans to take, including herbal medicines or other medicines available without a prescription.
The doctor should know that the patient is taking other medicines used to treat epilepsy or mental disorders. This will allow the doctor to determine the correct dose of Symla. These medicines include:
The patient should also tell their doctor if they are taking paracetamol, a medicine used to treat pain and fever.
Some medicines interact with Symla or increase the risk of side effects. These medicines include:
The doctor may recommend using a specific type of hormonal contraceptive or another method of contraception, such as a condom, diaphragm, or intrauterine device. If the patient is taking hormonal contraceptives, such as the pill, the doctor may recommend blood tests to check the level of Symla in the blood. If the patient is taking or plans to take hormonal contraceptives:
➢ Discuss this with your doctorabout the appropriate method of contraception.
Symla may also affect the action of hormonal contraceptives, although it is unlikely to reduce their effectiveness. If the patient is taking hormonal contraceptives and notices any changes in their menstrual cycle, such as bleeding or spotting:
➢ Tell your doctor. Such symptoms may indicate that Symla is affecting the action of the contraceptive.
➢ If the patient is pregnant, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
The active substance of Symla passes into breast milkand may affect the baby. The doctor will discuss the risks and benefits of breastfeeding while taking Symla and, if the patient decides to breastfeed, will check the baby from time to time to see if they are experiencing excessive sleepiness, rash, or poor weight gain. If any of these symptoms are noticed in the baby, tell the doctor.
Symla may cause dizziness and double vision.
➢ Do not drive or operate machinery unless the patient is sure that these symptoms do not occur.
If the patient has epilepsy, they should discuss driving and operating machinery with their doctor.
If the patient has been diagnosed with an intolerance to some sugars, they should consult their doctor before taking this medicine.

It may take some time to find the right dose of Symla for the patient. The dose taken by the patient depends on:
The doctor will initially prescribe a small dose and then gradually increase it over a few weeks until the effective dose for the patient (called the maintenance dose) is reached. Never take more Symla than your doctor has prescribed.
Usually, the maintenance dose of Symla in adults and children over 13 years of age is between 100 mg and 400 mg per day.
In children between 2 and 12 years of age, the maintenance dose is based on the child's weight - usually between 1 mg and 15 mg per kilogram of body weight, up to a maximum maintenance dose of 200 mg per day.
Symla is not recommended for children under 2 years of age.
Symla should be taken once or twice a day, as directed by the doctor. The medicine can be taken with or without food.
The doctor may also recommend starting or stopping other medicines, depending on the indication and the patient's response to treatment.
Symla tablets have a dividing line and can be divided into equal doses.
➢ Seek medical attention immediatelyat the emergency department of the nearest hospital. If possible, show the packaging of Symla.
Taking too much Symla may increase the risk of serious side effects, which can be fatal.
In a person who has taken too much Symla, the following symptoms may occur:
➢ Do not take a double dose to make up for the missed dose. Take the next dose at the usual time.
➢ Consult your doctor about how to restart taking Symla. This is important for the patient.
Symla must be taken for as long as the doctor recommends. Do not stop taking it unless the doctor tells you to.
If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
Taking Symla for epilepsy
To stop taking Symla, the dose should be gradually reducedover about two weeks. If Symla is stopped suddenly, the patient's epilepsy symptoms may return or worsen.
Taking Symla for bipolar affective disorders
It may take some time for Symla to start working, so it is unlikely that improvement will occur immediately. When stopping treatment with Symla, there is no need to gradually reduce the dose. However, the patient should consult their doctor if they plan to stop taking Symla.
Like all medicines, Symla can cause side effects, although not everybody gets them.
A small number of patients taking Symla may experience an allergic reaction or a potentially life-threatening skin reaction that can worsen if left untreated. Such reactions may occur more frequently during the first few months of taking Symla, especially if the patient has been given too high a dose or if the dose has been increased too quickly, or if the patient is taking Symla in combination with another medicine called valproate. Some of these reactions occur more frequently in children, so parents should pay particular attention to them.
The symptoms of these reactions include:
In many cases, these are symptoms of less severe side effects. However, remember that they can be life-threateningand, if left untreated, can develop into serious conditions, such as organ failure. If any of these symptoms occur:
➢ Seek medical attention immediately. The doctor may decide to perform liver, kidney, or blood tests and may recommend stopping Symla. If the patient experiences Stevens-Johnson syndrome or toxic epidermal necrolysis, the doctor will inform them that they should never take lamotrigine again.
