What is Fycompa?

Fycompa is an anticonvulsant used to treat seizures in adults and children.

Fycompa is used to treat partial onset seizures that may or may not develop into general seizures in people with epilepsy who are at least 4 years old.

Fycompa is also used with other medications to treat primary generalized tonic-clonic (PGTC) seizures in patients 12 years of age and older.

Warnings

Some people taking Fycompa have had serious psychotic effects, especially when starting this medicine or changing doses. Stay alert to changes in your mood or symptoms.

Call your doctor right away if you have any changes in mood or behavior changes, personality changes, thoughts about suicide, or thoughts about hurting others. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Before taking this medicine

You should not use Fycompa if you are allergic to perampanel.

To make sure Fycompa is safe for you, tell your doctor if you have:

• depression, a mood disorder, or other mental health problems;

• thoughts of hurting yourself or others;

• liver or kidney disease;

• drug addiction; or

• if you drink alcohol.

Some people taking Fycompa have had serious psychotic effects such as anger, aggression, feeling hostile or irritable, and thoughts about hurting others. These effects may be more likely to occur when you first start taking Fycompa, or whenever your dose is changed. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Do not start or stop taking seizure medication during pregnancy without your doctor's advice. Having a seizure during pregnancy could harm both mother and baby. Tell your doctor right away if you become pregnant.

Fycompa can make some birth control pills less effective. Ask your doctor about using a non-hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of perampanel on the baby.

It may not be safe to breastfeed while using Fycompa. Ask your doctor about any risk.

Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Do not stop using Fycompa suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
