What special precautions should I follow?[edit | edit source]

  • Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as multiorgan hypersensitivity, has been reported in patients taking XCOPRI. Discontinue if no alternate etiology.
  • This mediicne may cause QT Shortening. Use caution when administering XCOPRI with other drugs that shorten the QT interval.
  • Antiepileptic drugs (AEDs), including XCOPRI, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Monitor patients for suicidal behavior and ideation.
  • XCOPRI causes dose-dependent increases in somnolence and fatigue-related adverse reactions (somnolence, fatigue, asthenia, malaise, hypersomnia, sedation, and lethargy). Monitor for somnolence and fatigue and advise patients not to drive or operate machinery until they have gained sufficient experience on XCOPRI. Concomitant use with other CNS depressants or alcohol may have additive effects.
  • XCOPRI should be gradually withdrawn to minimize the potential of increased seizure frequency.
  • Do not drive, operate machinery, or do other dangerous activities until you know how XCOPRI affects you. XCOPRI may slow your thinking and motor skills and may affect your vision.
  • Do not drink alcohol or take other medicines that can make you sleepy or dizzy while taking XCOPRI without first talking to your healthcare provider.
