Phénobarbital pour l'épilepsie

About phenobarbital

If you have epilepsy, it means that you have had more than one unexplained fit, or seizure. A seizure is a short episode of symptoms caused by a burst of abnormal electrical activity in your brain. Different parts of the brain control different functions of your body, so the symptoms that occur during a seizure will depend on where the abnormal burst of electrical activity occurs. Symptoms that may occur during a seizure can affect your muscles, sensations, behaviour, emotions, consciousness, or a combination of these. The seizures can be prevented in most people by suitable anti-epileptic medication.

Phenobarbital works by stabilising the electrical activity of your brain, which helps to prevent the seizures from occurring.

Before taking phenobarbital

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 phenobarbital it is important that your doctor knows:

• Si vous êtes enceinte, si vous essayez d'avoir un enfant ou si vous allaitez.

• Si vous avez des problèmes respiratoires.

• If you have ever had problems with drug or alcohol dependence.

• Si vous avez des problèmes avec le fonctionnement de vos reins ou de votre foie.

• Si vous êtes atteint d'une maladie sanguine héréditaire rare appelée porphyrie.

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

• Si vous avez déjà eu une réaction allergique à un médicament.

How to take phenobarbital

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about phenobarbital and will provide you with a full list of the side-effects which you may experience from taking it.

• Take phenobarbital exactly as your doctor tells you to. It is usual to take one dose a day, at bedtime. Your doctor will tell you how many tablets to take for the dose. This information will also be printed on the label of the pack to remind you about what the doctor said to you. You need to take phenobarbital regularly every day to prevent the fits (seizures) from occurring.

• Try to take your doses of phenobarbital at the same time each evening. Having a routine like this will help you to remember to take your doses regularly. Swallow the phenobarbital tablets with a drink of water. You can take them either with or without food.

• Si vous oubliez de prendre une dose, prenez-la dès que vous vous en rendez compte, sauf s'il est presque temps de prendre la dose suivante, auquel cas ne prenez pas la dose oubliée. Ne prenez pas deux doses en même temps pour compenser une dose oubliée.

Tirer le meilleur parti de votre traitement

• Essayez de vous rendre à vos rendez-vous réguliers avec votre médecin. Il pourra ainsi vérifier vos progrès. Il se peut que vous deviez faire des analyses de sang de temps en temps.

• When you first start a new treatment for epilepsy there may be a change in the number or type of fits (seizures) you experience. Your doctor will advise you about this.

• Phenobarbital made by different manufacturers can act in a slightly different way in your body. Because of this, it is recommended that you continue to take tablets/medicine from the same manufacturer as you have had before. So, each time you collect a prescription, check to make sure your supply looks the same. If you are unsure, or if have any questions about your prescription, please ask your pharmacist to check it for you.

• Pendant que vous êtes traité pour une épilepsie, il existe un faible risque que vous développiez des changements d'humeur, des pensées angoissantes et des envies de suicide. Si cela se produit, vous devez en parler immédiatement à votre médecin.

• People with epilepsy must stop driving at first. Your doctor will advise you about when it may be possible for you to resume driving again. This will usually be after a year free of seizures.

• Do not stop taking this medicine unless your doctor tells you to do so. Stopping it suddenly can cause your seizures to return and your doctor will want you to reduce your dose gradually if this becomes necessary. Also, taking phenobarbital over a time can lead to your body becoming dependent on it and this is another reason why your doctor will want to reduce your dose slowly.

• You are advised not to drink alcohol while you are taking phenobarbital. Phenobarbital will make you feel sleepy and drinking alcohol will increase this. Some liquid medicines may contain noticeable amounts of alcohol, read the manufacturer's leaflet for more information.

• If you are due to have an operation or any dental treatment, please tell the person carrying out the treatment that you are taking phenobarbital.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take alongside phenobarbital.

• You should avoid becoming pregnant while you are taking phenobarbital because it could cause harm to your unborn baby.

• If you are a woman using hormonal contraception ('the pill' or the 'mini pill'), discuss this with your doctor, as phenobarbital interferes with these and could mean you are more likely to become pregnant. Other methods of contraception will be more suitable for you.

• If you want to have a family, make sure you discuss this with your doctor well in advance of becoming pregnant. This is so that you can be given advice from a specialist before you become pregnant. If you become pregnant while you are taking phenobarbital, you should tell your doctor straightaway.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.

The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
