Hi, I have hepitatis b infection in the liver. I need your advise if I should take viread medication if I have osteopenia and my kidney is not the best? I am currently taking oesteopenia pill. Please advise and help. Thanks a lot. I am worried about viread side effects on me. Another question is if I take the medicine, can I ever stop taking the medicine? Is it a life term medicine I have to take?
