Therefore, the patients of both HIV-1 infection and HBV infection should practice safe sex and should not share dirty needles.

    No, Tenofovir Alafenamide works best when taken with meals or just afterwards. However, taking it without food does not reduce its effectiveness.

    Q. For how long do I need to take Tenofovir Alafenamide for HBV infection?
