This medication is used to treat various cancers (e.g., leukemia, melanoma, AIDS-related Kaposi's sarcoma). It is also used to treat virus infections (e.g., chronic hepatitis B, chronic hepatitis C, condylomata acuminata). This medication is the same as a protein that your body naturally produces (interferon). In the body, it is thought to work by affecting cell function/growth and the body's natural defenses (immune system) in many ways. Adding more interferon may help your body fight off cancer or virus infections.
