Medication Summary

Pharmacotherapy is used rarely to reduce symptoms when needed. 



Class Summary

May inhibit transmission of impulses in neuromuscular tissue.

OnabotulinumtoxinA (BOTOX®)

Blocks neuromuscular conduction by binding to receptor sites on motor nerve terminals, entering the nerve terminals and inhibiting the release of acetylcholine. One treatment is usually sufficient, but in persistent cases, the injection may be repeated in 4-6 mo. Injection should be used only when symptoms are severe or when oscillopsia is present. Treatment of pediatric patients is not recommended.
