Patient leaflet - Fycompa 8 mg film-coated tablets

What Fycompa is and what it is used for

Fycompa contains a medicine called perampanel. It belongs to a group of medicines called anti epileptics. These medicines are used to treat epilepsy - where someone has repeated fits (seizures). It has been given to you by your doctor to reduce the number of fits that you have.

Fycompa is used in association with other antiepileptic drugs to treat certain forms of epilepsy:

In adults, adolescents (aged 12 years and older), and children (from 4 to 11 years)

* It is used to treat fits that affect one part of your brain (called a “partial seizure”).

* These partial seizures may or may not then be followed by a fit affecting all of your brain (called a “secondary generalisation”).

In adults and adolescents (aged 12 years and older), and children (from 7 to 11 years)

* It is also used to treat certain fits that affect all of your brain from the start (called “generalised seizures”) and cause convulsions or staring spells.

What you need to know before you take Fycompa

DO NOT TAKE Fycompa:

* If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking perampanel.

* If you are allergic to perampanel or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before taking Fycompa if you have liver problems or moderate or severe kidney problems. You should not take Fycompa if you have serious liver problems or moderate or serious kidney problems. Before taking this medicine you should tell your doctor if you have a history of alcoholism or drug dependence. Cases of increased liver enzymes have been reported in some patients taking Fycompa in combination with other antiepileptic drugs.

* Fycompa may make you feel dizzy or sleepy, particularly at the beginning of treatment.

* Fycompa may make you more likely to fall over, particularly if you are an older person; this might be due to your illness.

* Fycompa may make you aggressive, angry or violent. It may also cause you to have unusual or extreme changes in behaviour or mood, abnormal thinking and/or loss of touch with reality.

If you or your family and/or friends notice any of these reactions, talk to your doctor or pharmacist.

A small number of people being treated with anti-epileptics have had thoughts of harming or killing themselves. If at any time you have these thoughts, contact your doctor straight away.

Serious skin reactions including drug reaction with eosinophilia and systemic symptoms (DRESS) and Stevens - Johnson Syndrome (SJS) have been reported with the use of perampanel.

* DRESS typically, although not exclusively, appears as flu-like symptoms and a rash with a high body temperature, increased levels of liver enzymes seen in blood tests and an increase in a type of white blood cell (eosinophilia) and enlarged lymph nodes.

* Stevens - Johnson Syndrome (SJS) can appear initially as reddish target-like spots or circular patches often with central blisters on the trunk. Also, ulcers of mouth, throat, nose, genitals and eyes (red and swollen eyes) can occur. These serious skin rashes are often preceded by fever and/or flu-like symptoms. The rashes may progress to widespread peeling of the skin and life-threatening complications or be fatal.

If you experience any of the above after taking Fycompa (or you are not sure) talk to your doctor or pharmacist.

Children

Fycompa is not recommended for children aged under 4. The safety and effectiveness are not yet known in children under 4 years of age for partial seizures and under 7 years of age in generalised seizures.

Other medicines and Fycompa

Tell your doctor or pharmacist if you are taking or have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines. Taking Fycompa with certain other medicines may cause side effects or affect how they work. Do not start or stop other medicines without talking to your doctor or pharmacist. * Other anti-epileptic medicines, such as carbamazepine, oxcarbazepine, and phenytoin that are used to treat fits may affect Fycompa. Tell your doctor if you are taking or have recently taken these medicines as your dose may need to be adjusted.

* Felbamate (a medicine used to treat epilepsy) may also affect Fycompa. Tell your doctor if you are taking or have recently taken this medicine as your dose may need to be adjusted.

* Midazolam (a medicine used to stop prolonged, acute (sudden) convulsive seizures, for sedation and sleep problem) may be affected by Fycompa. Tell your doctor if you are taking midazolam as your dose may need to be adjusted.

Fycompa 8 mg film-coated tablets

* Some other medicines such as rifampicin (a medicine used to treat bacterial infections), hypericum (St. John’s Wort) (a medicine used to treat mild anxiety) and ketoconazole (a medicine used to treat fungal infections) may affect Fycompa. Tell your doctor if you are taking or have recently taken these medicines as your dose may need to be adjusted. * Hormonal contraceptives (including oral contraceptives, implants, injections, and patches)

Tell your doctor if you are taking hormonal contraceptives. Fycompa may make certain hormonal contraceptives such as levonorgestrel less effective. You should use other forms of safe and effective contraception (such as a condom or coil) when taking Fycompa. You should continue doing this for one month after stopping treatment. Discuss with your doctor what may be appropriate contraception for you.

Fycompa with alcohol

Speak to your doctor before drinking alcohol. Be careful about consuming alcohol with epilepsy medicines including Fycompa.

* Drinking alcohol while taking Fycompa can make you less alert and affect your ability to drive or use tools or machines.

* Drinking alcohol while taking Fycompa can also make any feelings of anger, confusion or sadness worse.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine. Do not stop treatment without first discussing it with your doctor. * Fycompa is not recommended in pregnancy.

* You must use a reliable method of contraception to avoid becoming pregnant while you are being treated with Fycompa. You should continue doing this for one month after stopping treatment. Tell your doctor if you are taking hormonal contraceptives. Fycompa may make certain hormonal contraceptives such as levonorgestrel less effective.

You should use other forms of safe and effective contraception (such as a condom or coil) when taking Fycompa. You should also do this for one month after stopping treatment. Discuss with your doctor what may be appropriate contraception for you.

It is not known whether the ingredients of Fycompa can pass into breast milk.

The doctor will weigh up the benefit and risks to your baby of taking Fycompa while you are breast-feeding.

Driving and using machines

Do not drive or use machines until you know how Fycompa affects you. You must talk to your doctor about the effect of your epilepsy on driving and using machines.

* Fycompa may make you feel dizzy or sleepy, particularly at the beginning of treatment. If this happens to you, do not drive or use any tools or machines.

* Drinking alcohol while taking Fycompa may make these effects worse.
