Recommendations

Stopping (futility) rules • Women of childbearing potential and/or their male
partners must use an effective form of contraception
Futility rules have been defined only with the triple combination during ribavirin-containing treatment and for a period of
6 months after the treatment has concluded (A1)
of PegIFN-a, ribavirin and simeprevir.
DAA-containing regimens
Recommendations New DAA regimens are generally well tolerated. Frequencies of
