Peginterferon alfa-2b injection is a synthetic (man-made) version of substances normally produced in the body to fight infection. Peginterferon alfa-2b injection is used alone or together with ribavirin and another drug called a hepatitic C virus (HCV) NS3/4A protease inhibitor (such as telaprevir or boceprevir) to treat chronic hepatitis C infection. It is used for patients who have never been treated by alpha interferons. The combination treatment of peginterferon alfa-2b and ribavirin is used to treat adults and children 3 years of age and older who show symptoms of liver damage.

Tacrolimus weakens your body's immune system, to help keep it from "rejecting" a transplanted organ such as a kidney. Organ rejection happens when the immune system treats the new organ as an invader and attacks it.

Tacrolimus is used together with other medicines to prevent your body from rejecting a heart, liver, or kidney transplant.

Tacrolimus may also be used for purposes not listed in this medication guide.
