PEGASYS, like other alpha interferons, may cause or worsen fatal or life-threatening problems (like mental, immune system, heart, liver, lung, intestinal and infections).

Ribavirin, including COPEGUS®, can cause birth defects and/or death to an unborn baby. Female patients and the female partners of male patients should avoid getting pregnant.
