Narcolepsia is a problem which affects your sleep. Disturbed night-time sleep makes you feel very tired and drowsy during the daytime, and you can also have times where you fall asleep during the day without any warning. Many people with narcolepsy also have cataplexy. Cataplexy is a condition in which you suddenly lose control over some of your muscles.

Sodium oxybate is used to treat narcolepsy when cataplexy is also a problem. It helps with excessive daytime sleepiness as well as helping the symptoms of cataplexy. It is sometimes used in combination with other medicines for narcolepsy.

Before taking sodium oxybate

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 sodium oxybate it is important that your doctor or pharmacist knows:

  • Se você está grávida, tentando ter um bebê ou amamentando.

  • Se você tem epilepsia.

  • If you have any problems with your heart or your breathing, or if you have high blood pressure.

  • If you have problems with your liver or kidneys.

  • If you are on a 'low sodium' diet for medical reasons.

  • Se você já teve uma doença depressiva.

  • Se você tem porfiria, um raro distúrbio sanguíneo hereditário.

  • If you have ever had a drug addiction problem.

  • Se você estiver tomando outros medicamentos. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

  • Se você já teve uma reação alérgica a um medicamento.

How to take sodium oxybate

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about sodium oxybate and a full list of side-effects which you may experience from taking it.

  • Take sodium oxybate exactly as your doctor tells you to. When starting this treatment your doctor will give you a small dose and then gradually increase it. This is to make sure you have the dose that helps your condition and avoids any unwanted symptoms.

  • It is taken in two doses - the first dose taken as you go to bed, and the second dose 2½-4 hours later. You should prepare both doses before you retire to bed, and you may need to set an alarm to make sure you wake up to take the second dose.

  • Only use the special child-resistant dosing cups provided with Xyrem® for storing your diluted doses.

  • Sit upright whilst taking your doses. Take your second dose whilst still in bed and lie down again straightaway.

  • Food interferes with how much of this medicine is absorbed by your body, so it is important that you take sodium oxybate well after eating any food. Most doctors will recommend that it is taken at a set time each evening, at least 2-3 hours after your evening meal.

  • Mix each of your doses with water (see below).

  • If you forget to take the first dose, take it as soon as you remember and then take the second dose 2½-4 hours later. If you forget to take the second dose, do not take it when you remember but instead skip the dose completely and do not take any more until the following evening. Do not take two doses together to make up for a forgotten dose.
