Baclofen is a muscle relaxant.
It's used to relieve muscle spasms, cramping or tightness caused by conditions such as:
- cerebral palsy
- meningitis
- motor neurone disease
- multiple sclerosis
- conditions affecting your brain, spinal cord and nervous system
Baclofen is available on prescription. It comes as tablets or a liquid that you swallow.
If baclofen tablets or liquid do not work well for you or your child, you may be prescribed a baclofen injection. This will be given by a specialist doctor in hospital. Baclofen can also be given through a pump that is fitted under the skin.
Key facts
- Baclofen reduces pain and discomfort caused by muscle spasms.
- The tablets and liquid start to work after 1 hour after taking it. However, it might take a few days before you find the right dose to control your symptoms.
- Common side effects include feeling sleepy and feeling sick (nausea).
- If your doctor decides to stop your treatment, your dose will be reduced gradually over 1 to 2 weeks.
- It's best not to drink alcohol while you are taking baclofen until you know how it affects you. There's a risk alcohol may increase drowsy side effects and make you very sleepy.
