IMPORTANT WARNING

People who have taken perampanel have developed serious or life-threatening changes in their mental health and behavior, especially increased hostility or aggression toward others. Tell your doctor if you have or have ever had any type of mental illness or aggressive behavior. However, you should know that it is possible to develop these changes in mental health and behavior while taking perampanel even if you have never had any problems with mental health or behavior in the past. You, your family, or your caregiver should call your doctor right away if you experience any changes in mood, behavior, or personality during your treatment with perampanel or for up to a month after stopping your treatment. Your doctor will monitor your mental health closely during your treatment with perampanel, especially when you begin taking this medication and any time that your dose is changed. If you experience any of the following symptoms, call your doctor immediately: aggression, hostility, anger, anxiety, irritability, suspicious or distrustful behavior, and thinking about harming or killing others or threatening or trying to do so. Your doctor may decrease your dose or stop your medication.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with perampanel and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.

Talk to your doctor about the risks of taking perampanel.

WHY is this medicine prescribed?

Perampanel is used in combination with other medications to treat certain types of seizures in people who are 12 years of age or older. Perampanel is in a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain.

HOW should this medicine be used?

Perampanel comes as a tablet to take by mouth. It is usually taken once a day at bedtime. Take perampanel at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take perampanel exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on a low dose of perampanel and gradually increase your dose, not more than once every one to two weeks.

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

Perampanel may help control your condition but does not cure it. Do not stop taking perampanel without talking to your doctor. If you suddenly stop taking perampanel, your seizures may become worse. Your doctor will probably decrease your dose gradually.

Are there OTHER USES for this medicine?

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

What SPECIAL PRECAUTIONS should I follow?

Before taking perampanel,

  • tell your doctor and pharmacist if you are allergic to perampanel, any other medications, or any of the ingredients in perampanel tablets. Ask your pharmacist or check the Medication Guide for a list of the ingredients.
  • tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take. Be sure to mention any of the following: antidepressants; barbiturates such as phenobarbital and secobarbital (Seconal); medications for allergies,anxiety, cough and cold, mental illness, and pain; medications for seizures such as carbamazepine (Carbatrol, Tegretol, Equetro), oxcarbazepine (Trileptal, Oxtellar), phenytoin (Dilantin, Phenytek), primidone (Mysoline), and topiramate (Topamax); rifampin (Rifadin); sedatives; sleeping pills; and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with perampanel, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
  • you should know that perampanel may decrease the effectiveness of hormonal contraceptives (birth control pills, patches, rings, or implants) that contain levonorgestrel. Use another form of birth control while taking perampanel. Ask your doctor or pharmacist if you are not sure if your birth control contains levonorgestrel.
  • tell your doctor what herbal products you are taking, especially St. Johns wort.
  • tell your doctor if you drink or have ever drunk large amounts of alcohol, if you use or have ever used street drugs, or if you have over-used prescription medications. Also tell your doctor if you have or have ever had kidney or liver disease.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking perampanel, call your doctor.
  • you should know that perampanel may cause dizziness, drowsiness, and problems with coordination and balance. This may increase the risk of falls that can cause serious injury, especially if you are elderly. Do not drive a car, operate machinery, or participate in activities requiring alertness or coordination until you know how this medication affects you.
  • ask your doctor about the safe use of alcoholic beverages while you are taking perampanel. Alcohol can make the side effects from perampanel worse.
  • you should know that your mental health may change in unexpected ways and you may become suicidal (thinking about harming or killing yourself or planning or trying to do so) while you are taking perampanel. A small number of adults and children 5 years of age and older (about 1 in 500 people) who took anticonvulsants like perampanel to treat various conditions during clinical studies became suicidal during their treatment. Some of these people developed suicidal thoughts and behavior as early as 1 week after they started taking the medication. There is a risk that you may experience changes in your mental health if you take an anticonvulsant medication such as perampanel, but there may also be a risk that you will experience changes in your mental health if your condition is not treated. You and your doctor will decide whether the risks of taking an anticonvulsant medication are greater than the risks of not taking the medication. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: panic attacks; agitation or restlessness; new or worsening irritability, anxiety, or depression; acting on dangerous impulses; difficulty falling asleep or staying asleep; aggressive, angry, or violent behavior; mania (frenzied, abnormally excited mood); talking or thinking about wanting to hurt yourself or end your life; or any other unusual changes in behavior or mood. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.

What SPECIAL DIETARY instructions should I follow?

Unless your doctor tells you otherwise, continue your normal diet.

What should I do IF I FORGET to take a dose?
