Baclofen Aguettant belongs to a group of medicines called muscle relaxants. Baclofen Aguettant is administered by injection into the spinal canal directly into the spinal fluid (intrathecal injection) and relieves severe muscle rigidity (spasticity).

Baclofen Aguettant is used to treat severe, long-lasting muscle tension (spasticity) occurring in various illnesses, such as:

  • brain or spinal cord injuries or diseases,
  • multiple sclerosis, which is a progressive brain and spinal cord nerve disease with physical and mental symptoms.

Baclofen Aguettant is used in adults and children aged 4 years and above. It is used when other orally taken medicines, including baclofen, have been unsuccessful or caused unacceptable side effects.

  • If you have reduced circulation of liquid contained in the brain and spinal cord as a result of obstructed passage, for example caused by inflammation or injuries.
  • Contact your doctor immediately if you think that Baclofen Aguettant is not working as well as usual. It is important to make sure that there are no problems with the pump.
  • Treatment with Baclofen Aguettant must not stop suddenly because of the risk of withdrawal effects. You must make sure that you do not miss those hospital visits when the pump reservoir is being refilled.
  • Your doctor may want to give you a check-up from time to time while you are being treated with Baclofen Aguettant.
  • Tell your doctor immediately if you get any of these symptoms during treatment with Baclofen Aguettant:

If you have pain in your back, shoulders, neck and buttock during the treatment (a type of spinal deformity called scoliosis).

Children and adolescents

Baclofen Aguettant is not recommended for children under 4 years. Children should be of sufficient body mass to accommodate the implantable pump for chronic infusion. There is very limited clinical data regarding the safety and efficacy of the use of Baclofen Aguettant in children under the age of four year.

Other medicines and Baclofen Aguettant

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Some medicines can interfere with your treatment. Remind your doctor or nurse if you are taking any of the following:

  • Other medicines for your spastic condition
  • Medicines to treat depression
  • Medicines for high blood pressure
  • Medicines for Parkinson’s disease
  • Strong pain relief medicines, such as morphine
  • Medicines which slow down the function of the central nervous system, such as sleep inducing medicines

Baclofen Aguettant and alcohol

  • Avoid drinking alcohol during treatment with Baclofen Aguettant as this may lead to an undesirable intensification or unpredictable change in the effects of the medicine.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Pregnancy

There is limited experience on the use of intrathecal baclofen during pregnancy. Baclofen Aguettant should not be used during pregnancy, unless the doctor finds it necessary and the expected benefit for the mother outweighs the potential risk for the child.

Breast-feeding

Baclofen Aguettant passes into breast milk, but in amounts so small that the infant will probably not experience any undesirable effects. Ask your doctor for advice before using Baclofen Aguettant during breast-feeding.

Driving and using machines

Some people may feel drowsy and/or dizzy or have problems with their eyes while they are being treated with Baclofen Aguettant. If this happens, you should not drive or do anything that requires you to be alert (such as operate tools or machinery) until these effects have worn off.

Baclofen Aguettant contains sodium

This medicinal product contains less than 1 mmol sodium (23 mg) per unit volume, that is to say essentially “sodium-free”.

3. how to use baclofen aguettant

Baclofen Aguettant is administered by intrathecal injection. This means that the medicine is injected directly into the spinal fluid. The dose needed varies from person to person depending on their condition, and the doctor will decide what dose you need after he/she has tested your response to the drug.

First of all the doctor will find out, by giving you single doses of Baclofen Aguettant, whether it is suitable for you. Usually, this test dose is administered via lumbar puncture or an intrathecal (spinal) catheter, in order to provoke a response. During this period your heart and lung functions will be closely monitored. If your symptoms improve, a special pump which can deliver the drug continuously, will be implanted into your chest or abdominal wall. The doctor will give you all of the information you need to use the pump and to get the correct dosage. Make sure that you understand everything.

The final dose of Baclofen Aguettant depends on how each person responds to the drug. You will be started on a low dose, and this will be increased gradually over a few days, under the supervision of the doctor, until you are having the dose which is right for you. If the starting dose is too high, or if the dose is increased too quickly, you are more likely to experience side effects.

It is extremely important that you keep your appointment with the doctor to refill the pump. To avoid unpleasant side effects which may be serious and even life-threatening, it is important that your pump does not run out. The pump must always be filled by a doctor or nurse, and you must make sure that you do not miss your clinic appointments.

Efficacy of baclofen intrathecal has been demonstrated in clinical studies using a pump system to deliver baclofen directly into the spinal fluid (infusion systems). An EU certified pump system is implanted beneath your skin, mostly into the abdominal wall. The pump stores and releases the right amount of medicine through the catheter directly into your spinal fluid.

During long-term treatment some patients find that Baclofen Aguettant becomes less effective. You may require occasional breaks in treatment. Your doctor will advise you what to do.

To open the package of Baclofen Aguettant, please hold the package with the two hands and turn the edges in opposite way until the opening.

If treatment with Baclofen Aguettant is interrupted It is very important that you, and those caring for you, are able to recognise signs of Baclofen Aguettant withdrawal. These signs may appear suddenly or slowly for example because the pump or delivery system is not working properly.

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 Aguettant than you should

It is very important that you, and anyone caring for you, can recognise the signs of overdose. These may appear if the pump is not working properly, and you must tell the doctor straight away.

Signs of overdose are:

  • Unusual muscle weakness (too little muscle tone)
  • Sleepiness
  • Dizziness or light-headedness
  • Excessive salivation
  • Nausea or vomiting
  • Difficulty in breathing Convulsions
  • Loss of consciousness
  • Abnormally low body temperature

If you have any further questions on the use of this product, ask your doctor or pharmacist.
