The objective of this study is to determine the tolerability and safety of Myfortic in liver transplant patients. Patients receiving CellCept who have GI side effects will have CellCept discontinued and changed to Myfortic (Myfortic is a new drug similar to CellCept, except it is enteric-coated). Our hypothesis is that Myfortic has less GI side effects and will, therefore, be tolerated better than CellCept and also that Myfortic will have a comparable effectiveness to CellCept.

||Conversion of CellCept to Myfortic: A Prospective Study on the Tolerability and Safety of Myfortic in Liver Transplant Recipients
Primary Outcome Measures:
- Gastrointestinal Side Effects and Quality of Life (Total Score of GSRS) [ Time Frame: screening, 2, 6 and 12 weeks ]
The gastrointestinal Symptom Rating Scale (GSRS) is a validated scale, the items range from 1= No discomfort at all to 7= Very severe discomfort.
The scale ranges from a minimal value of 15 ( No discomfort at all) to a maximum of 105 ( Very severe discomfort)
The GSRS contains 15 items, each rated on a seven- point likert scale from no discomfort to very severe discomfort. Based on a factor analysis, the 15 GSRS items breakdown into the following five scales: abdominal ( Abdominal pain, hunger pains and nausea): reflux syndrome (heartburn and acid regurgitation), diarrhea syndrome (diarrhea, loose stools and urgent need for defecation), indigestion syndrome ( borborygmus, abdominal distention, eructation and increased flatus) and constipation syndrome (constipation, hard stools and feeling of incomplete evacuation)
- Number of Participants With Cytomegalovirus Infection or Disease [ Time Frame: 12 weeks ]
- Gastrointestinal Side Effects and Quality of Life (-Subscales of GSRS) [ Time Frame: 12 weeks ]
The GSRS contains 15 items, each rated on a seven- point likert scale from no discomfort to very severe discomfort. Based on a factor analysis, the 15 GSRS items breakdown into the following five scales: abdominal ( Abdominal pain, hunger pains and nausea): reflux syndrome (heartburn and acid regurgitation), diarrhea syndrome (diarrhea, loose stools and urgent need for defecation), indigestion syndrome ( borborygmus, abdominal distention, eructation and increased flatus) and constipation syndrome (constipation, hard stools and feeling of incomplete evacuation) The range of the scale for abdominal pain was 3 to 21, reflux 2 to 14, diarrhea 3 to 21, indigestion 4 to 28 and constipation 3 to 21.
Higher values represent more severe discomfort.

Experimental: Liver Transplant Subjects
All subjects in this study will receive Myfortic 360mg or 720 mg BID for 90 days.
Myfortic 360mg or 720 mg BID for 90 days.
This is a prospective, single center, open-label, safety and tolerability study on the use of Myfortic after liver transplantation. Adult liver transplant patients who are experiencing GI symptoms (nausea, vomiting, diarrhea, abdominal discomfort/pain, dyspepsia) attributable to CellCept are eligible to enter the study. CellCept will be discontinued and replaced with Myfortic. The duration of the study will be 3 months, and during this time, we will assess the incidence and severity of GI adverse events, the incidence and severity of bone marrow suppression (leukopenia), and the incidence of cytomegalovirus (CMV) infection or disease in patients receiving Myfortic.
