About perampanel for epilepsy
|Type of medicine||An anti-epileptic medicine|
|Used for||Epilepsy in adults and in children aged over 12 years|
Perampanel is used alongside other medicines in the treatment of seizures. A seizure is a short episode of symptoms which is caused by a burst of abnormal electrical activity in the brain. Generalised seizures occur if you have a burst of abnormal electrical activity which spreads throughout the brain. Generalised seizures affect consciousness and may cause a convulsion. With a focal seizure, the burst of electrical activity stays in one part of the brain and therefore you tend to have localised or 'focal' symptoms. Because different parts of the brain control different functions, your symptoms will depend on which part of your brain is affected. Focal seizures can sometimes develop into seizures which affect all of your brain. These are called secondary generalised seizures.
Perampanel is prescribed alongside other anti-epileptic medicines. It works by stabilising the electrical activity in your brain.
Before taking perampanel
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking perampanel it is important that your doctor knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have any problems with the way your liver works, or if you have any problems with the way your kidneys work.
- If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to take perampanel
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about perampanel, and it will also provide you with a full list of the side-effects which you could experience from taking it.
- Take perampanel exactly as your doctor tells you to. You will be asked to take a low dose when you first start taking it, and then your dose will be increased as your body gets used to it. Your doctor or pharmacist will explain this to you, and directions will also be printed on the label of the pack to remind you about what the doctor said to you.
- Perampanel is taken as a once-daily dose at bedtime. Try to avoid missing any doses. If you do forget, just take your next dose when it is due - do not take two doses together to make up for a forgotten dose.
- Swallow the tablet whole with a drink of water. Do not chew, break or crush the tablet. Perampanel can be taken with or without food.
- There are several strengths of perampanel tablets and each strength is a different colour. When you collect a new supply, check to make sure they are the colour you are expecting. If not, ask your pharmacist to check it out for you.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
- When you first start a new treatment for epilepsy there may be a change in the number or type of seizures you experience. Your doctor will advise you about this.
- Perampanel could make you feel sleepy, especially when you first start treatment.
- While you are being treated for epilepsy there is a small risk that you may develop mood changes, distressing thoughts and feelings about suicide. If this happens, you must tell your doctor about it straightaway.
- People with epilepsy must stop driving at first. Your doctor will advise you about if and when it may be possible for you to resume driving again.
- Drinking alcohol while you are on perampanel can increase the risk of side-effects and may not be recommended for you. Ask for your doctor's advice.
- Many anti-epileptic medicines can harm an unborn child. If you are a woman, make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. If you want to have a family, discuss this with your doctor so that you can be given advice from a specialist before you become pregnant.
- You need to take perampanel regularly every day. Do not stop taking it unless your doctor tells you to stop. Stopping treatment suddenly can cause problems and your doctor will want you to reduce your dose gradually if this becomes necessary.
