Botox / Dysport Intramuscular Injections


What is a Botox / Dysport Injection?

  • Botulinum Toxin type A (commercially available as Botox or Dysport) is well known for its use in cosmetics, but it has actually been used for years to treat spasticity in juvenile cerebral palsy and is also used to treat certain forms of pain.
  • When used for pain management, Botox is designed to stop muscle spasming for a period of up to 4 months.
  • Local anaesthetic and Botox are injected onto the spasming muscle, usually the shoulder, neck and/or back areas.
  • For more information, read our educational news article on Intramuscular Botox for Pain.


Prior to the Procedure

  • If you are taking any blood thining products you will need to check with the clinic if you are required to cease this prior to your injection procedure.
    • You may continue to take aspirin.
  • You will need to organise someone to drive you home after the procedure as you will not be able to drive for 4 hours after your procedure.


What Will Happen?

  1. The medical officer will speak with you prior to your injection.
  2. The tender spots (or trigger points) will be palpated and marked with a marking pen.
  3. The area will then be cleaned with a chlorhexidine solution or alcohol wipe.
  4. Botox and local anaesthetic will be injected.
  5. The injection procedure takes approximately 15 minutes.
  6. You will be allowed home with your driver after your injection.

  • During the first 5 days you may experience some pain at the site of the injection and some flu-like symptoms.
  • Other possible side effects include headache, temporarily increased pain, irritation of nerves at the injection site, and rarely paralysis of muscle outside the area of spasm.
