What is PegIntron?
PegIntron is a prescription medicine that is used:
- with REBETOL (ribavirin) and an approved hepatitis C virus (HCV) protease inhibitor to treat chronic (lasting a long time) hepatitis C infection in adults.
- with REBETOL (ribavirin) to treat chronic (lasting a long time) hepatitis C infection in people 3 years and older with stable liver problems.
- alone, sometimes to treat adults who have chronic (lasting a long time) hepatitis C infection with stable liver problems and who cannot take REBETOL (ribavirin).
People with hepatitis C have the virus in their blood and in their liver. PegIntron reduces the amount of virus in the body and helps the body’s immune system fight the virus. REBETOL (ribavirin) is a drug that helps to fight the viral infection but does not work when used by itself to treat chronic hepatitis C.
It is not known if PegIntron use for longer than 1 year is safe and will work.
It is not known if PegIntron use in children younger than 3 years old is safe and will work.
