1. WHAT BACLOFEN IS AND WHAT IT IS USED FOR

Baclofen is a medicine to relieve severe muscle spasms (antispastic).

Your doctor has decided that you or your child needs this medicine to help treat your condition.

Baclofen is intended for adults and children of 4 years and above and is used to reduce and relieve the excessive tension in your muscles (spasms) occurring in various illnesses such as cerebral palsy, multiple sclerosis, spinal cord diseases, cerebrovascular accidents, and other nervous system disorders.

For this purpose the doctor will inject single injections (bolus injections) of Baclofen 0.05mg/1ml into your spinal cord to test whether this will result in an improvement in your symptoms.

2. BEFORE YOU USE BACLOFEN Do not use Baclofen

-    if you are allergic (hypersensitive) to baclofen or any of the other ingredients of Baclofen.

-    if you have epilepsy that is untreatable.

Take special care with Baclofen

-    if you have abnormal flow of cerebral spinal fluid (liquor) as a result of obstructed passage,

-    epilepsy or other cerebral seizures,

-    bulbar paralytic symptoms or partial paralysis (pareses) of the respiratory muscles (neurological syndromes caused by damage to the motor cranial nerves in the elongated spine),

-    acute or chronic confusional states,

-    psychotic disorders, schizophrenia or Parkinson's disease,

-    history of abnormal autonomic nervous system reflexes,

-    inadequate blood flow in the brain and difficulty breathing (cerebrovascular and respiratory insufficiency),

-    pre-existing overactivity of the bladder sphincter muscle,

-    cardiac problems,

-    impaired renal function,

-    stomach and intestinal ulcers (peptic ulcers),

-    severely impaired hepatic function.

For patients with spasticity due to head injury, it is recommended not to proceed to long-term Baclofen therapy until the symptoms of spasticity are stable and can be reliably assessed.

Children and adolescents

Baclofen intrathecal formulation is intended for children of 4 years and above. Children should be of sufficient body mass to accommodate the implantable pump. There is very limited clinical data in children under the age of six.

Elderly patients

Several patients over the age of 65 years have been treated with Baclofen during the clinical trials without specific problems. Experience with Baclofen tablets shows however that this patient group may be more susceptible to side effects. Elderly patients should therefore be carefully monitored for the occurrence of side effects

Using Baclofen with other medicines

Please tell your doctor or pharmacist if you are taking/using or have recently taken/used any other medicines, including medicines obtained without a prescription.

No specific studies have been carried out on interactions with other medicines.

The following medicines may interact with Baclofen or Baclofen may interact with them:

-    Medicines to relieve severe muscle spasms (antispastics).

-    Medicines that have depressant effects on the functions of the central nervous system.

-    Medicines to treat depression (tricyclic antidepressants).

-    Medicines used to treat high blood pressure.

It may be necessary for the doctor to adjust the dose of Baclofen or one of your other medicines.

Using Baclofen with food and drink

Drinking alcohol while using Baclofen should be avoided as this may lead to an undesirable intensification or unpredictable change in the effect of the medicine.

Pregnancy and breast-feeding

There is no experience on the use of Baclofen during pregnancy or while breast-feeding. Baclofen should not be used during pregnancy or while breast-feeding unless the potential benefit to the mother outweighs the potential risk to the child. Baclofen passes into breast milk. As so far there are no adequate studies available the concentration cannot be predicted.

Driving and using machines

During treatment with Baclofen your ability to drive or operate machines may be considerably impaired.

Do not drive, operate machines or participate in any other hazardous activities.

In particular it should be noted that drinking alcohol at the same time further intensifies this decreased alertness.

Important information about some of the ingredients of Baclofen

Baclofen 0.05 mg/1 ml solution for injection contains less than 1 mmol sodium (23 mg) per maximum dose of 2 ml (corresponding to 100 microgram baclofen).

3. HOW TO USE BACLOFEN

Always use Baclofen exactly as your doctor has told you.

At a first stage the doctor will find out by single injections of Baclofen 0.05mg/l ml if this improves your muscular spasms. If this is the case a special pump will be implanted under your skin, which permits continuous delivery of small quantities of Baclofen.

It may take several days to find out the optimal dose for you. Once the optimum treatment is established, your doctor must check your progress and functioning of the pump at regular intervals.

Intrathecal use.

Baclofen can be administered only by qualified specialist doctors by direct injection or infusion in the back (spinal cord), for which special medical equipment is needed. For this reason hospitalisation will be necessary at the beginning of therapy.

If your muscle spasticity is not improving or if you start having spasms again, either gradually or suddenly, contact your doctor immediately.

If treatment with Baclofen is interrupted

It is very important that you, and those caring for you, are able to recognise signs of Baclofen withdrawal. These may appear suddenly or slowly for example because the pump is not working properly due to battery problems, catheter problems or alarm dysfunction.

The signs of withdrawal are: increased spasticity, too much muscle tone

-    difficulty with muscle movements

-    increase in heart rate or pulse

-    itching, tingling. burning sensation or numbness (paraesthesia) in your hands or feet

-    palpitations

-    anxiety

-    high body temperature

-    low blood pressure

-    altered mental conditions for example agitation, confusion, hallucinations, abnormal thinking and behaviour, convulsions

If you have any of the above signs, tell your doctor straight away. These signs may be followed by more serious side effects unless you are treated immediately.

If you use more Baclofen than you should

It is very important that you, and those caring for you, are able to recognise the signs of overdose. These may appear suddenly or slowly for example because the pump is not working properly.

The signs of overdose are:

-    muscle weakness (too little muscle tone)

-    sleepiness

-    dizziness or light-headedness

-    excessive salivation (hypersalivation)

-    nausea or vomiting
