WHY is this medicine prescribed?

Brivaracetam injection is used to treat partial onset seizures (seizures that involve only one part of the brain) in people who cannot take oral medication. Brivaracetam is in a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain.

HOW should this medicine be used?

Brivaracetam injection comes as a solution (liquid) to be injected intravenously (into a vein) over a period of 2 to 15 minutes. It is given twice a day for as long as you are unable to take brivaracetam tablets or oral solution by mouth.

Your doctor may increase or decrease your dose depending on how well the medication works for you, and the side effects you experience. Be sure to tell your doctor how you are feeling during your treatment with brivaracetam.

Brivaracetam may be habit forming. Do not use a larger dose, use it more often, or use it for a longer period of time than prescribed by your doctor.

Brivaracetam may help control your condition but will not cure it. Continue to use brivaracetam even if you feel well. Do not stop using brivaracetam injection without talking to your doctor, even if you experience side effects such as unusual changes in behavior or mood. If you suddenly stop using brivaracetam, your seizures may become worse. Your doctor will probably decrease your dose gradually.

Are there OTHER USES for this medication?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
