Patient leaflet - Brivaracetam Celix 100 mg film-coated tablets

1. What Brivaracetam Film-coated Tablets are and what are they used for

What Brivaracetam Film-coated Tablets are

Brivaracetam Film-coated Tablets contain the active substance brivaracetam. It belongs to a group of medicines called ‘anti-epileptics’. These medicines are used to treat epilepsy.

What Brivaracetam

Film-coated Tablets are used for

  • Brivaracetam Film-coated

    Tablets are used in adults, adolescents and children from 2 years of age.

  • They are used to treat

    a type of epilepsy that has partial seizures with or without a secondary generalisation.

  • Partial seizures are fits that start by only affecting one side of

    the brain. These partial seizures can spread and extend to larger areas on both sides of the brain – this is called a ‘secondary generalisation’.

  • You have been given this medicine to lower the number of

    fits (seizures) you have.

  • Brivaracetam Film-coated Tablets are used together with

    other medicines for epilepsy.

2. What you need to know before you take Brivaracetam Film-coated Tablets

Do not take Brivaracetam Film-coated Tablets if:

  • you are allergic to brivaracetam, other similar chemical

    compounds as levetiracetam or piracetam or any of the other ingredients of this medicine (listed in section 6). If you are not sure, talk to your doctor or pharmacist before taking Brivaracetam Film-coated Tablets.

  • you have ever developed a severe skin rash or skin peeling,

    blistering and/or mouth sores after taking brivaracetam. Serious skin reactions including Stevens-Johnson syndrome have been reported in association with brivaracetam treatment. Stop using Brivaracetam Film-coated Tablets and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.

Warnings and precautions

Talk to your doctor or pharmacist before taking Brivaracetam Film-coated Tablets if:

  • You have thoughts of harming or killing yourself. A small

    number of people being treated with anti-epileptic medicines such as brivaracetam have had thoughts of harming or killing themselves. If you have any of these thoughts at any time, contact your doctor immediately.

  • You have liver problems - your doctor may need to adjust

    your dose.

    Children

    Brivaracetam Film-coated Tablets are not recommended for use in children under 2 years of age.

    Other medicines and Brivaracetam Film-coated Tablets

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

    In particular, tell your doctor if you are taking any of the following medicines – this is because your doctor may need to adjust your Brivaracetam Film-coated Tablets dose:

    • Rifampicin - a medicine used to treat bacterial infections.
    • St John’s wort (also known as Hypericum perforatum) - a herbal medicine used to treat depression and anxiety as well as other conditions.

Brivaracetam Film-coated Tablets with alcohol

  • Combining this medicine with alcohol is not recommended.
  • If you drink alcohol while taking Brivaracetam Film-coated

    Tablets the negative effects of alcohol may be increased.

Pregnancy and breast-feeding

Fertile women should discuss the use of contraceptives with the doctor.

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

It is not recommended to take Brivaracetam Film-coated Tablets if you are pregnant, as the effects of brivaracetam on pregnancy and the unborn baby are not known.

It is not recommended to breast-feed your baby while taking brivaracetam, as brivaracetam passes into breast milk. Do not stop treatment without talking to your doctor first. Stopping treatment could increase your seizures and harm your baby.

  • You may feel sleepy, dizzy or tired while taking Brivaracetam

    Film-coated Tablets.
