Brief Summary:
This study will compare neurologic side effects associated with two immunosuppressant medications used in liver transplant patients. The standard therapy of twice daily immediate release Tacrolimus will be compared to Envarsus once daily. We hypothesize that Envarsus will show a lower rate of neurologic side effects than immediate release tacrolimus.

Drug Information available for: Tacrolimus

Arm Intervention/treatment
Active Comparator: Arm 1: Control
Tacrolimus immediate release twice daily for 6 months
Drug: Tacrolimus Immediate release
Subjects in this group will take Tacrolimus immediate release for 6 months of treatment (goal 12 hour trough: 3-10 ng/mL) +/- adjunctive agent and prednisone.

Experimental: Arm 2: Intervention
Envarsus daily for 6 months.
Drug: Envarsus
Subjects in this group will take Envarsus daily for 6 months of treatment (goal 24 hour trough: 3-10 ng/mL) +/- adjunctive agent and prednisone.

Primary Outcome Measures :
  1. Change in neurotoxicity burden [ Time Frame: 6 months ]
    Estimate the change from baseline to six months in neurotoxicity burden measured by a composite Patient Global Impression of Improvement score

Secondary Outcome Measures :
  1. Change in mean Fahn-Tolosa-Marin (FTM) score [ Time Frame: 6 months ]
    Estimate the change in the mean FTM score among patients with self-reported tremors from baseline to six months.
