  • Effectiveness
    Slight (for essential tremor)
  • Side effects
    Mild (grogginess)
  • Adherence
    Always
  • Burden
    A little hard to take
Dosage: 200 mg Daily
Advice & Tips: Started before took sinemet, and had slight effect on tremor. When sinemet was started, had more effect on tremor than primidone. When sinemet was increased to six pills daily, tried to decrease primidone and found could do so with no increase in tremor.
Cost: < $25 monthly
Side effects: grogginess
