Neuromuscular Blockers

These agents suppress tics and possibly premonitory sensations.

OnabotulinumtoxinA (BOTOX)

This agent inhibits release of acetylcholine at neuromuscular junction; it is injected directly into muscle. It is most useful for dystonic tics (eg, sustained eye closure) or only 1 or 2 especially problematic tics (eg, repeatedly flinging head to 1 side causing neck pain and broken glasses). Tics and tic urges may improve; effect can be seen in absence of gross weakness. Successful outcomes require substantial specialized experience in the treating physician.
