What this medicine is used for

The name of your medicine is Chemmart Baclofen Tablets. It contains the active ingredient baclofen.

It is used to treat:

  • multiple sclerosis
  • spinal cord damage resulting from disease or physical injury.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

This medicine is available only with a doctor’s prescription.

How it works

Baclofen belongs to a group of medicines called muscle relaxants.

It is used to reduce excess tension in your muscles which causes spasms. Because this medicine reduces spasms and the pain that goes with them, it helps to make you more mobile. This helps you to manage your daily activities more easily.

There is no evidence that this medicine is addictive.

Use in children

Baclofen should be used with extreme caution in children under 16 years of age as only limited information is available. Baclofen should not be used in children who weigh less than 33 kg.

Some medicines may interact with baclofen. These include:

  • any medicine that tends to make you sleepy, such as medicines used to help you sleep, calm down (e.g. diazepam), relax muscles (e.g. tizanidine), pain relievers (e.g. morphine), travel sickness medicines and medicines for colds or allergies. These may add to the sedative effect of baclofen. Alcohol will also have this effect.

  • medicines for high blood pressure
  • medicines used to treat Parkinson’s disease, including levodopa and carbidopa
  • medicines used to treat diabetes

Other medicines not listed above may also interact with baclofen.

How to take this medicine

Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.

How much to take

Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.

You would normally start by taking small doses of baclofen in hospital.

The dose is then gradually increased to an amount that works best for you. For example, baclofen may be started at a dose of 15 mg a day, then increased slowly to anywhere from 30 to 75 mg a day. Sometimes, doses up to 100 mg a day may be needed.

If you are under the age of 16 or over 65, or you have kidney disease, your doctor may start you on a lower dose and increase it more gradually to prevent side effects.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the tablets with some water.

When to take it

Take the tablets during meals. This will lessen the chance of a stomach upset

Baclofen is usually taken in at least three divided doses throughout the day. But your doctor may tell you to take it more or less often, depending on your situation.

Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.

Your doctor will check your progress to make sure the medicine is working and will discuss with you how long your treatment should continue.

Do not stop taking baclofen suddenly. This medicine is not habit-forming, but stopping it suddenly may bring on severe spasms and other side effects.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively, go to the Accident and Emergency department at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. If you take too much baclofen you may feel drowsy, have problems breathing or lose consciousness.

You may also feel confused, hallucinate (imagine things that are not there), have unusual muscle weakness, blurred vision, feel sick (nausea), be sick (vomit), faint, have diarrhoea, increased saliva, slow or irregular heartbeat, or fits (seizures).

Do not:

  • Give this medicine to anyone else, even if their symptoms seem similar to yours.

  • Stop taking your medicine, or change the dosage, without first checking with your doctor.

Be careful when driving or operating machinery until you know how this medicine affects you.

Be careful when drinking alcohol while you are taking baclofen. The combination may make you feel more sleepy, dizzy or lightheaded and less alert than usual.
