What is a Botox injection?
Botox is a medication derived from a naturally occurring bacterial protein. It is widely and safely used in many areas of medicine.
When injected into a muscle in very small amounts, it reduces excessive muscle activity, allowing the muscle to relax.
The effect is temporary and usually lasts a few months, after which treatment can be repeated if required.
How does the injection work?
In children with muscle tightness due to neurological conditions (such as cerebral palsy), Botox reduces muscle overactivity and improves flexibility.
Can the injection be repeated?
Yes. Botox injections can be safely repeated once the effect wears off.
Current evidence shows no long-term harm from repeated treatments when administered appropriately.
Where is the injection given?
Although it can technically be administered in clinic, this is generally not recommended.
To ensure accuracy:
For comfort and precision, the procedure is usually performed in theatre under a short anaesthetic.
Is Botox safe?
Botox is very safe when injected correctly into muscle.
If accidentally injected into the bloodstream, it could cause symptoms similar to food poisoning — this is avoided by:
Checking the syringe position before injection
Is it painful?
The medication itself does not cause pain.
Discomfort comes from needle placement.
Because precise positioning is required, children are usually given a short anaesthetic so they do not feel the injections.
What should be watched for afterwards?
Side effects are uncommon.
Rarely, temporary weakness of breathing or swallowing muscles can occur.
For safety, children are observed in hospital for a few hours after the procedure before discharge.
Is Botox approved for cerebral palsy?
Yes. Botulinum toxin injections are recommended by NICE (National Institute for Health and Care Excellence) for treating spastic muscles in children with cerebral palsy:

Botox treatment is most effective when combined with physiotherapy, stretching programmes and appropriate orthotic support.
