Hepatitis C virus was discovered nearly 30 years ago, and for the first two decades, treatment was limited to agents with low response rates and substantial side effects. Since the introduction of direct-acting antivirals, there have been rapid advances made toward even higher sustained virologic responses (SVRs) and fewer side effects. This chapter provides a review of the newer agents for treatment of hepatitis C and highlights special populations, including those coinfected with HIV or hepatitis B, previously treated patients, and post-liver transplant patients.
