Botox / Dysport Intramuscular Injections


What is a Botox / Dysport Injection?

  • Botulinum Toxin type A (commercially available as Botox or Dysport) has been used for years to treat spasticity in juvenile cerebral palsy and more recently in cosmetic surgery.
  • 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.
  • Possible side effects include headache, flu-like symptoms, paralysis of muscle outside the area of spasm (rare), temporary exacerbation of pain and irritation of nerves at site of injection.
