Cannabisextrakt gegen Muskelspastik

About cannabis extract

Nerve fibres in your brain and spinal cord carry tiny electrical messages (impulses) between your brain and muscles allowing you to move. The nerve fibres are protected by a special protein 'coat' known as myelin which helps the electrical impulses travel quickly. In Multiple Sklerose (MS) areas of this protective coat become damaged which means the nerve fibres cannot control your muscles properly. This can lead to symptoms such as shaking (tremors) or spasms of some of your muscles.

Some muscles may also shorten (contract) tightly and can then become stiff and harder to use. This is called spasticity. Cannabis extract in the form of Sativex® spray is used to relieve the symptoms of spasticity in people with MS. This can help you to move your muscles more easily and with less pain. Cannabis extract cannot repair the damage to the myelin coat. It works by affecting certain natural chemicals (called neurotransmitters) in your brain which control the nerve impulses to your muscles.

Sativex® is used alongside other medicines, to relieve spasticity when those medicines are no longer as effective. Sativex® can only be prescribed by a doctor who specialises in treating MS symptoms. You will be prescribed an initial trial of this medicine to see if it is right for you.

Sativex® oromucosal spray is a specially prepared medicine that contains ingredients that have been extracted from the cannabis plant. Unlike using or smoking cannabis, Sativex® should not make you feel 'high' when being taken at prescribed doses. Sativex® may make you feel dizzy and drowsy, or give you a feeling like being drunk, especially when you first start taking it. If this does not settle down, or if it becomes troublesome, you may need to reduce your dose and ask your doctor for advice.

Before taking cannabis extract (Sativex®)

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 cannabis extract it is important that your doctor knows:

• If you are pregnant or trying for a baby.

• If you are breastfeeding (cannabis extract will be present in your milk and can affect your baby).

• If you have any problems with your heart or blood vessels.

• Wenn Sie hohen Blutdruck (Hypertonie) haben.

• Wenn Sie Epilepsie haben.

• If you, or any member of your immediate family, have experienced mental health problems known as psychosis or schizophrenia.

• If you have any problems with the way your liver or kidneys work.

• Wenn Sie jemals von Drogen oder Alkohol abhängig waren.

• Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

• Wenn Sie andere Medikamente einnehmen. Dazu gehören alle Medikamente, die Sie einnehmen und die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Medikamente.
  

How to take cannabis extract (Sativex®)

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

• Take cannabis extract exactly as your doctor tells you to. When you first start using Sativex® spray, your doctor will ask you to increase your dose gradually over a period of two weeks. This will help you to find the dose that controls your symptoms whilst keeping side-effects to a minimum.

• During this initial trial period carefully follow the instructions your doctor has given you to find the right dose. After the first few days you will need to increase your dose by one spray each day until you have relief from your symptoms or until you are using 12 sprayed doses per day.

• Morning doses can be taken any time between waking and midday. Evening doses should be taken any time between 4 pm and bedtime. It is important to leave at least 15 minutes between each spray.

• Once you have found the daily dose that works for you, carry on using Sativex® spray at this same dose. Your doctor will review your progress and together you can decide whether to continue using cannabis extract.

• Only use Sativex® spray in your mouth by pointing the nozzle under your tongue or at the inside of your cheek. Try to use it on a different area of your mouth each time so as to avoid any irritation developing.

• Try not to eat or drink anything immediately before or after your doses.

• If you forget to take a dose, take it as soon as you remember or when you feel you need it. Do not take two doses together to make up for a missed one.

Das Beste aus Ihrer Behandlung herausholen

• Try to keep all your regular appointments with your doctor. This is so your doctor can check on your progress. Your treatment will be reviewed after four weeks of taking cannabis extract and then on a regular basis if you continue.

• Ask your doctor for advice about drinking alcohol. Your doctor may recommend that you do not drink alcohol while taking cannabis extract because it increases the possibility of side-effects such as feeling dizzy and sleepy.

• If you are a driver, please be aware that cannabis extract is likely to affect your reactions and ability to drive. It is an offence to drive while your reactions are impaired. Even if your driving ability is not impaired, you are advised to carry with you some evidence that the medicine has been prescribed for you - a repeat prescription form or a patient information leaflet from the pack is generally considered suitable.

• For some people, if you have been unable to move your muscles for some time they may have become too weak to fully support you. Then, if this medicine helps you move again, you may have difficulty standing or be at risk of falling over. Be aware of this and take care when moving about. Ask your doctor for advice on physiotherapy or exercises to strengthen your muscles.

• It is not yet known how cannabis extract might affect pregnancies or the developing baby. For this reason you are advised to use reliable contraception during treatment and for three months after stopping.

• If you are planning a trip abroad, you are advised to carry a letter with you from your doctor to explain that you have been prescribed cannabis extract. This is because cannabis extract is classed as a 'controlled drug' and is subject to certain restrictions.

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

• If you buy any medicines, check with your doctor or a pharmacist that they are suitable for you to take with cannabis extract.
