I had been told that adding local to botulinum toxin might block receptors that pick up the agent and hence decrease its effectiveness. A study using saline only and lidocaine- botulinum combo found no difference.

  • “Eight patients were injected with 50 U of BTX-A diluted in 0.5 mL of saline and 1 mL of 2% lidocaine into one axilla and 50 U of BTX-A diluted in 1.5 mL of saline into the other axilla in a randomized fashion.”
  • equal in onset, effectiveness and duration of decreased sweating
  • Injection the lidocaine group was considered less painful
