  • 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.
  • Briviact is used together with other medicines for epilepsy.

2. What you need to know before you take Briviact

Do not use Briviact 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 Briviact.

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 Briviact if you are pregnant, as the effects of Briviact on pregnancy and the unborn baby are not known. It is not recommended to breast-feed your baby while taking Briviact, as Briviact 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 using Briviact.
  • 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.
