1. What Brivaracetam MSN is and what it is used for
What Brivaracetam MSN is

This medicine contains the active substance brivaracetam. It belongs to a group of medicines called ‘anti-epileptics’. These medicines are used to treat epilepsy.

What Brivaracetam MSN is used for
  • Brivaracetam MSN is used in adults, adolescents and children from 2 years of age.
  • It is 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 MSN is used together with other medicines for epilepsy.

2. What you need to know before you take Brivaracetam MSN
Do not take Brivaracetam MSN 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 MSN.
  • you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking Brivaracetam MSN.

Serious skin reactions including Stevens-Johnson syndrome have been reported in association with Brivaracetam MSN treatment. Stop using Brivaracetam MSN 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 MSN if:

  • You have thoughts of harming or killing yourself. A small number of people being treated with anti-epileptic medicines such as brivaracetam MSN 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 MSN is not recommended for use in children under 2 years of age.

Other medicines and Brivaracetam MSN

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 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 MSN with alcohol
  • Combining this medicine with alcohol is not recommended.
  • If you drink alcohol while taking brivaracetam 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 MSN if you are pregnant, as the effects of Brivaracetam MSN on pregnancy and the unborn baby are not known.

It is not recommended to breast-feed your baby while taking Brivaracetam MSN, as Brivaracetam MSN passes into breast milk.

Do not stop treatment without talking to your doctor first. Stopping treatment could increase your seizures and harm your baby.

Driving and using machines
  • You may feel sleepy, dizzy or tired while taking Brivaracetam MSN.
  • These effects are more likely at the start of the treatment or after a dose increase.
  • Do not drive, cycle or use any tools or machines until you know how the medicine affects you.
