1. What is Lacosamida Alter and what is it used for

What is Lacosamida

This medicine contains lacosamida, which belongs to a group of medicines called “antiepileptic medicines”. These medicines are used to treat epilepsy.

  • You have been prescribed this medicine to reduce the number of seizures you are having.

What is lacosamida used for

  • Lacosamida is used:
  • on its own and with other antiepileptics in adults, adolescents, and children from 2 years of age to treat a certain type of epilepsy characterized by the occurrence of partial-onset seizures with or without secondary generalization. In this type of epilepsy, the seizures affect only one side of your brain. However, they can then spread to larger areas on both sides of your brain;
  • with other antiepileptics in adults, adolescents, and children from 4 years of age to treat primary generalized tonic-clonic seizures (grand mal seizures, with loss of consciousness) in patients with idiopathic generalized epilepsy (a type of epilepsy that is believed to have a genetic origin).

2. What you need to know before you take Lacosamida Alter

Do not take Lacosamida Alter

  • if you are allergic to lacosamida or any of the other ingredients of this medicine (listed in section 6). If you are not sure, consult your doctor.
  • if you have a heart rhythm problem called second or third degree AV block.

Do not take lacosamida if any of the above applies to you. If you are not sure, consult your doctor or pharmacist before taking this medicine.

Warnings and precautions

Consult your doctor before starting to use lacosamida if:

  • you have thoughts of self-harm or suicide. A small number of people taking antiepileptics such as lacosamida have had thoughts of self-harm or suicide. If at any time you have these thoughts, contact your doctor immediately.
  • you have a heart problem that affects your heartbeat and your pulse is often particularly slow, fast, or irregular (such as AV block, atrial fibrillation, and atrial flutter)
  • you have severe heart disease such as heart failure or have had a heart attack.
  • you often feel dizzy or faint. Lacosamida may cause dizziness, which could increase the risk of accidental injury or falls. This means you should be careful until you are used to the effects of this medicine.

If any of the above applies to you (or you are not sure), consult your doctor or pharmacist before taking lacosamida.

If you are taking lacosamida, consult your doctor if you experience a new type of seizure or worsening of existing seizures. If you are taking lacosamida and experience symptoms of abnormal heartbeat (such as slow, fast, or irregular heartbeat, palpitations, shortness of breath, dizziness, fainting), consult your doctor immediately (see section 4).

Children

Lacosamida is not recommended in children under 2 years of age with epilepsy characterized by the occurrence of partial-onset seizures or in children under 4 years of age with primary generalized tonic-clonic seizures. This is because it is not yet known if it is effective and safe for children of this age group.

Other medicines and Lacosamida Alter

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines that affect the heart, as lacosamida may also affect the heart:

  • medicines for heart problems;
  • medicines that can increase the “PR interval” in a heart test (ECG or electrocardiogram) such as epilepsy or pain medicines called carbamazepine, lamotrigine, or pregabalin;
  • medicines used to treat certain types of arrhythmia or heart failure.

If any of the above applies to you (or you are not sure), talk to your doctor or pharmacist before taking lacosamida.

Tell your doctor or pharmacist if you are taking any of the following medicines, as they may also increase or decrease the effect of lacosamida in your body:

  • antifungal medicines called fluconazole, itraconazole, or ketoconazole;
  • a medicine for HIV called ritonavir;
  • antibacterial medicines called clarithromycin or rifampicin;
  • a herbal medicine used to treat mild anxiety and depression called St. John's Wort.

If any of the above applies to you (or you are not sure), talk to your doctor or pharmacist before taking lacosamida.

Taking Lacosamida Alter with alcohol

As a precaution, do not take lacosamida with alcohol.

Pregnancy and breastfeeding

Women of childbearing age should discuss the use of contraceptives with their doctor.

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Lacosamida is not recommended during pregnancy, as the effects of lacosamida on pregnancy and the fetus are not known.

It is not recommended to breastfeed while taking Lacosamida, as lacosamida passes into breast milk.

Ask your doctor for advice immediately if you are pregnant or plan to become pregnant. They will help you decide whether to take lacosamida or not.

Do not stop treatment without talking to your doctor first, as this could increase the risk of seizures (fits). Worsening of your condition may also harm the fetus.

Driving and using machines

Do not drive, ride a bike, or use any tools or machines until you know if this medicine affects you. The reason is that lacosamida may cause dizziness or blurred vision.

3. How to take Lacosamida Alter

Follow exactly the administration instructions of this medicine given by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again. Another form of this medicine may be more suitable for children; consult your doctor or pharmacist.

Taking Lacosamida

  • Take lacosamida twice a day, with an interval of approximately 12 hours.
  • Try to take it more or less at the same time every day.
  • Take the lacosamida tablet with a glass of water.
  • You can take lacosamida with or without food.

Normally, you will start by taking a low dose each day and your doctor will gradually increase the dose over several weeks. When you reach the dose that works well for you, called the “maintenance dose”, you will take the same amount every day. Lacosamida is used as long-term treatment. You will need to keep taking lacosamida until your doctor tells you to stop.

How much to take

The following are the usual recommended doses of lacosamida for different age and weight groups. Your doctor may prescribe a different dose if you have kidney or liver problems.

Adolescents and children weighing 50 kg or more and adults

When taking lacosamida alone:

The usual starting dose is 50 mg twice a day.

Your doctor may also prescribe a starting dose of 100 mg of lacosamida twice a day. Your doctor may increase the dose you take twice a day by 50 mg each week, until you reach a maintenance dose between 100 mg and 300 mg twice a day.

When taking lacosamida with other antiepileptic medicines:

The usual starting dose is 50 mg twice a day.

Your doctor may increase the dose you take twice a day by 50 mg each week, until you reach a maintenance dose between 100 mg and 200 mg twice a day.

If you weigh 50 kg or more, your doctor may start lacosamida treatment with a single “loading dose” of 200 mg. You will then start taking the continuous maintenance dose 12 hours later.

Children and adolescents weighing less than 50 kg

  • In the treatment of partial-onset seizures:note that lacosamida is not recommended for children under 2 years of age.
  • In the treatment of primary generalized tonic-clonic seizures:note that lacosamida is not recommended for children under 4 years of age.

The dose depends on body weight. Treatment is usually started with the oral solution and only changed to tablets if the patient is able to take them and to get the correct dose with tablets of different strengths. Your doctor will prescribe the formulation that best suits you.

If you take more Lacosamida Alter than you should

If you have taken more lacosamida than you should, talk to your doctor immediately. Do not attempt to drive.

You may experience:

  • dizziness;
  • feeling sick (nausea) or being sick (vomiting);
  • seizures (fits), heart rhythm problems such as slow, fast, or irregular pulse, coma, or low blood pressure with rapid heart rate and sweating.

In case of overdose or accidental ingestion, consult your doctor, pharmacist, or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medicine and the amount taken.

If you forget to take Lacosamida Alter

  • If you have forgotten to take a dose within the next 6 hours after the scheduled dose, take it as soon as you remember.

  • If you have forgotten to take a dose after 6 hours after the scheduled dose, do not take the missed dose. Instead, take lacosamida the next time you normally would.
  • Do not take a double dose to make up for missed doses.

If you stop taking Lacosamida Alter

  • Do not stop taking lacosamida without telling your doctor, as your epilepsy may come back or get worse.
  • If your doctor decides to stop your treatment with lacosamida, they will give you instructions on how to gradually decrease the dose.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
