    Perampanel Uses:

  • Perampanel is used for treating certain kinds of partial-onset seizures (seizures that are only one part of the brain) in adults and children who are 4 years of age and older. It is also used in conjunction with other medications to treat certain types of primary generalised tonic-clonic seizures (formerly known as a grand mal seizure; seizure involving the entire body) in adults and children aged 12 and up.
  • How to use :

    • Perampanel is available as a tablet and a suspension (liquid) for oral administration. It is usually taken at bedtime once in a day. Follow the instructions on your prescription label carefully, and if there is anything you don't understand, ask your doctor or pharmacist to explain it to you. Perampanel should be taken exactly as directed. Do not take more or less of it, and don’t take it more frequently than your doctor has prescribed.
    • Before each use, give the suspension a good shake to ensure that the drug is evenly distributed.
    • To prepare and measure your dosage, always use the oral dosing syringe that comes with perampanel suspension. Do not measure your dosage with a regular spoon.
    • Your doctor will most likely start you on a low dose of perampanel and gradually increase it once a week or less.
    • Perampanel has the potential to become addictive. Do not take a higher dose, take it more frequently, or take it for a longer period of time than your doctor has prescribed.
    • Perampanel will help you manage your condition, but it won't make it go away. Do not stop taking a perampanel without first consulting your physician. Seizures may become worse if you suddenly stop taking a perampanel. Your doctor will most likely gradually reduce your dose.
