Summary

People find the injections used in onabotulinumtoxinA (Botox®) uncomfortable. This study will test whether putting a small piece of cotton soaked with 4% lidocaine (a numbing medicine) inside the front of each nostril for 5 minutes before the injections reduces injection pain compared with cotton soaked in saline (salt water).

Conditions

  • Pain From onabotulinumtoxinA Injections

Interventions

PROCEDURE

onabotulinumtoxinA prophylaxis with Lidocaine

The onabotulinumtoxinA prophylaxis procedure is the modified PREEMPT protocol consisting of 56 injections; 200 Units. The solution from the vial (lidocaine) will be dripped onto 2 small pieces of cotton. One piece of cotton will be placed in the anterior portion of the nasal cavity on each side of the nose. The cotton will be removed after 5 minutes. The clinician will then perform the various series of injections while assessing pain of the injection site following each series of injections.
