Drug
Interferon Alfa-2B
Pronounced
"in-ter-FEER-on AL-fuh"
Uses
This medication is used to treat various cancers (such as leukemia, melanoma, AIDS-related Kaposi's sarcoma). It is also used to treat virus infections (such as 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.
Warning
This medication can rarely cause or worsen serious (rarely fatal) medical conditions, including mental/mood conditions (such as depression), immune system problems (autoimmune conditions such as lupus or rheumatoid arthritis), circulation problems, or infections. If your medical history includes any of these conditions, tell your doctor promptly. Also, tell your doctor right away if any serious symptoms or side effects occur (see Side Effects section).
This medication may be combined with ribavirin to treat chronic hepatitis C. Ribavirin may cause harm to an unborn baby or death. Women must avoid pregnancy while they or their male partners are using ribavirin. Ribavirin may cause a blood disorder (hemolytic anemia), which can worsen heart disease. If you are using this medication with ribavirin to treat chronic hepatitis C, also carefully read the drug information for ribavirin.
