What is the most important information I should know about Briviact?

Briviact is a federally controlled substance (CV) because it can be abused or lead to dependence. Keep Briviact in a safe place to prevent misuse and abuse. Selling or giving away Briviact may harm others and is against the law.

Like other antiepileptic drugs, Briviact may cause suicidal thoughts or actions in a very small number of people, about 1 in 500 people taking it.

Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • new or worse depression
  • feeling agitated or restless
  • trouble sleeping (insomnia)
  • acting aggressive, feeling angry, or being violent
  • an extreme increase in activity and talking (mania)
  • attempts to commit suicide
  • new or worse anxiety
  • panic attacks
  • new or worse irritability
  • acting on dangerous impulses
  • other unusual changes in behavior or mood

Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.

How can I watch for early symptoms of suicidal thoughts and actions?

  • Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings.
  • Keep all follow-up visits with your healthcare provider as scheduled.

Call your healthcare provider between visits as needed, especially if you are worried about symptoms.
