1. What is Trelema and what is it used for

What is Trelema

Trelema contains the active substance lacosamide. It belongs to a group of medicines called antiepileptics, which are used to treat epilepsy.
This medicine has been prescribed by the doctor to reduce the number of seizures.

What is Trelema used for

• Trelema is used:
• as monotherapy and in combination with other antiepileptic medicines in adults, adolescents, and children from 2 years of age for the treatment of a type of epilepsy characterized by partial seizures and secondary generalized partial seizures. In this type of epilepsy, seizures initially affect only one side of the brain but may then spread to other areas on both sides of the brain.
• in combination with other antiepileptic medicines in adults, adolescents, and children from 4 years of age for the treatment of primary generalized tonic-clonic seizures (grand mal seizures involving loss of consciousness) in patients with generalized idiopathic epilepsy (a type of epilepsy considered to be genetic in origin).

2. Important information before taking Trelema

When not to take Trelema

• if the patient is allergic to lacosamide or any of the other ingredients of this medicine (listed in section 6); in case of doubts about the occurrence of an allergy, the doctor should be consulted.
• if the patient has a certain type of heart rhythm disorder, called second or third degree atrioventricular block.

Trelema should not be taken if any of the following situations apply to the patient. In case of doubts, the doctor or pharmacist should be consulted.

Warnings and precautions

Before starting to take Trelema, the doctor should be consulted if:

• the patient is thinking about self-harm or suicide. In a small number of patients taking antiepileptic medicines, such as lacosamide, thoughts of self-harm or suicide have occurred. If such thoughts occur, the doctor should be contacted immediately.
• the patient has heart rhythm disorders, which are very often slowed, accelerated, or irregular (such as atrioventricular block, atrial fibrillation, or atrial flutter).
• the patient has severe heart disease, such as heart failure, or has had a heart attack.
• the patient often experiences dizziness or falls. Trelema may cause dizziness, which can increase the risk of accidental injuries or falls. This means that the patient should be particularly careful until they get used to the effect of this medicine.

If any of the above situations apply to the patient (or if the patient has doubts), before taking Trelema, they should consult their doctor or pharmacist.
If Trelema is taken, the doctor should be informed about any new type of seizures or worsening of existing seizures.
If the patient takes Trelema and experiences symptoms of abnormal heart rhythm (such as slow, fast, or irregular heartbeat, palpitations, shortness of breath, dizziness, fainting), they should immediately consult their doctor (see section 4).

Children

Trelema is not recommended for children under 2 years of age with epilepsy characterized by partial seizures or for children under 4 years of age with primary generalized tonic-clonic seizures. The efficacy of the medicine in children of this age is not yet known, and it is not known if it is safe for them.

Trelema and other medicines

The doctor or pharmacist should be informed about all medicines the patient is currently taking or has recently taken, as well as any medicines the patient plans to take.
In particular, the doctor or pharmacist should be informed about the use of the following medicines, which affect heart function:

• medicines used for heart diseases
• medicines that prolong the PR interval, which is visible in the ECG recording, such as medicines used for epilepsy or pain treatment, e.g., carbamazepine, lamotrigine, or pregabalin
• medicines used for certain heart rhythm disorders or heart failure If any of the above situations apply to the patient (or if the patient has doubts), before taking Trelema, they should consult their doctor or pharmacist.

The doctor or pharmacist should also be informed if the patient is taking any of the following medicines, as they may cause a decrease or increase in the effect of Trelema:

• medicines used for fungal infections, such as fluconazole, itraconazole, or ketoconazole
• medicine used for HIV infection, such as ritonavir
• medicines used for bacterial infections, such as clarithromycin or rifampicin
• herbal medicine used for mild depression, containing St. John's Wort (Hypericum perforatum)

If any of the above situations apply to the patient (or if the patient has doubts), before taking Trelema, they should consult their doctor or pharmacist.

Trelema and alcohol

For safety reasons, alcohol should not be consumed while taking Trelema.

Pregnancy and breastfeeding

Women of childbearing age should discuss the use of contraception with their doctor.
If the patient is pregnant or breastfeeding, or thinks they may be pregnant or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
Trelema should not be taken during pregnancy, as its effect on the course of pregnancy and the unborn child is not known.
Breastfeeding is not recommended while taking Trelema, as Trelema passes into breast milk. The patient should immediately consult their doctor if they become pregnant or plan to become pregnant. The doctor will help decide whether to continue taking Trelema.
The patient should not stop taking the medicine without consulting their doctor, as this may cause an increase in the number of seizures. The worsening of the disease in the mother can also harm the child.

Driving and operating machines

The patient should not drive a car or ride a bicycle, or use any tools or operate machines until they are sure what effect the medicine has on them, as Trelema may cause dizziness or blurred vision.
This medicine contains30 mg of sodium (main component of table salt) in each vial or 60 mg of sodium in each ampoule. This corresponds to 1.5% or 3% of the WHO-recommended maximum daily sodium intake of 2 g for an adult.

3. How to take Trelema

This medicine should always be taken as directed by the doctor. In case of doubts, the doctor or pharmacist should be consulted.
