Hello and welcome to ask a doctor.  I reviewed your query and here is my answer. As you said the patient has chronic hep b and had liver transplant. So he is taking these Chat Doctor.  As some books has mentioned that hep b patient should take treatment for lifelong even there PCR is negative. Hope I answered your question.  Feel free to ask more if you need further assistance.  Thanks.
