If HD chorea requires treatment, clinicians should prescribe tetrabenazine 9up to 100mg/day), amantadine (300-400 mg/day), or riluzole (200 mg/day) (Level B) for varying degrees of expected benefit. Occurrence of adverse events should be discussed and monitored, particularly depression/suicidality parkinsonism with tetrabenazine and elevated liver enzymes with riluzole. |
