Must be used in combination with PEG-interferon and ribavirin (see separate entries)
Combination treatment is contra-indicated in pregnant women and men whose female partners are pregnant because of the risks for birth defects and fetal death associated with ribavirin, or in coadministration with drugs that are highly dependent on CYP3A4/5 for clearance, or with potent CYP3A4/5 inducers.
