Comprimés

narcolepsie is a long-term problem that affects your sleep. You feel excessively tired during the daytime but have disturbed night-time sleep. You can also have sleep attacks where you fall asleep at inappropriate times during the day without any warning.

Although there is no cure for narcolepsy, modafinil can help to control your symptoms. Modafinil works by stimulating the central nervous system to increase your alertness and reduce excessive sleepiness during the day.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking modafinil it is important that your doctor knows:

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

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

  • If you have a heart condition or high blood pressure (hypertension).

  • If you have ever had a mental health problem such as depression, psychosis or mania.

  • If you have ever had a problem with drug or alcohol misuse.

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

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

Note de l'auteur clinique Michael Stewart 01/03/2020: Based on post-marketing reports from the USA, modafinil (Provigil®) may harm an unborn child. Modafinil should not be used during pregnancy. Women of childbearing potential must use effective contraception during treatment with modafinil and for two months after stopping. Discuss with your doctor which forms of contraception are suitable for you, as hormonal contraceptives are made less effective by modafinil. Alternative treatment options for narcolepsy should be used during pregnancy, such as behaviour modifications, good sleeping habits and scheduled daytime naps.

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

  • Take the tablets exactly as your doctor tells you to. There are two strengths of tablet available - 100 mg and 200 mg. When you first start modafinil it is usual to be prescribed a dose of 200 mg daily. You may be asked to take this as a single dose of 200 mg in the morning, or divided into 100 mg in the morning and 100 mg at midday. Your doctor or pharmacist will tell you which is right for you. Your dose may be increased after a little while, depending upon your symptoms.

  • Take your doses with a drink of water to help you swallow the tablet. Do not break or crush the tablet - it should be swallowed whole. You can take modafinil before or after food.

  • If you forget to take a dose, miss out the forgotten dose completely but make sure that you remember to take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

  • Keep your regular appointments with your doctor so that your progress can be monitored. You may need to have your blood pressure and heart rate checked regularly.

  • Modafinil can cause blurred vision or dizziness in some people and therefore it may affect your ability to use tools or machines, so take care when using them. Sleepiness associated with your condition can add to this.

  • Taking modafinil is not a replacement for a good sleep routine. It is still important that you aim to get around eight hours of sleep at night if possible. You should try to go to sleep and get up at about the same time each day.

  • In the UK, you are required by law to let the Driver and Vehicle Licensing Authority (DVLA) know if you are diagnosed with narcolepsy. You may be allowed to drive again when your symptoms are well controlled with medication, but you will need to have regular reviews. Your doctor will advise you about this.

  • Modafinil should not be used during pregnancy. Women of childbearing potential must use effective contraception during treatment with modafinil and for two months after stopping.

  • Hormonal contraceptives, including oral contraceptive pills, implants, intrauterine contraceptive devices (IUCDs) and contraceptive patches, are less effective when used with modafinil and are therefore not recommended. Speak to your doctor about which contraceptive methods are suitable for you while you are taking modafinil.

  • If you are planning to become pregnant you should stop taking modafinil and try alternative treatment options such as good sleep habits and scheduled daytime naps.

  • If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking modafinil.
