Dantrolen för kronisk muskelspasm

About dantrolene

Dantrolene belongs to a group of medicines called muscle relaxants. Muscle relaxants are medicines that are used to prevent or reduce muscle spasms and spasticity. Muscle spasms occur when there is an uncontrolled (involuntary) contraction of a group of muscles. This often causes pain and discomfort. Spasticity occurs when the muscles contract tightly and then become stiff and harder to use.

Dantrolene is used to relieve muscle spasms and spasticity which result from long-term conditions affecting the nervous system, such as multipel skleros, motor neurone disease eller cerebral palsy, or following long-term injuries to the head or back. It works by causing the muscles to relax and this reduces pain and discomfort.

Before taking dantrolene

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 dantrolene it is important that your doctor knows:

• If you have any problems with the way your liver works, or if you have a heart condition, or if you have any difficulties with your breathing.

• Om du är gravid eller ammar.

• Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

How to take dantrolene

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

• When starting the treatment, your doctor will give you a small dose (usually one 25 mg capsule daily) and will then gradually increase your dose at weekly intervals. This allows your doctor to make sure that you have the dose that helps your condition but avoids any unwanted symptoms.

• Swallow the capsule with a drink of water. You can take dantrolene either before or after a meal.

• Continue to take dantrolene exactly as your doctor tells you to. Your dose will be printed on the label of the pack to remind you about what your doctor said to you. Once you are established on a regular dose of dantrolene, try to take your doses at the same times of day each day, as this will help you to remember to take them.

• If you do forget to take a dose, take it when you remember unless your next dose is about due. If it is nearly time for your next dose then take the next dose when it is due but leave out the forgotten dose. Do not take two doses together to make up for a missed dose.
  

Få ut det mesta av din behandling

• Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress, as it may take a few weeks before you begin to feel the benefit from dantrolene.

• If after six weeks or so you don't feel you are improving, please speak with your doctor about this, as your treatment could need reviewing.

• Dantrolene can cause drowsiness and may affect your reactions. Be careful this does not put you at risk if you are using any tools or machines, or if you drive.

• It is recommended that you do not drink alcohol while you are on dantrolene. This is because the risk of side-effects, such as feeling sleepy and dizzy, is increased.

• Treatment with dantrolene is usually long-term unless you experience an adverse event. Continue to take the capsules unless your doctor tells you otherwise. If your muscle spasms increase or if you have difficulty doing things because you feel your muscles have become weak, let your doctor know about this, as your dose may need adjusting.

• Om du ska genomgå en operation eller tandbehandling, informera den som utför behandlingen om vilka mediciner du tar.
