Pegylated interferon

Pegylated interferon is a medication used to treat certain infections and some types of cancer. It is a form of interferon, a naturally occurring protein that helps the immune system fight viruses and abnormal cells. The "pegylated" part means the interferon has been chemically attached to a small molecule called polyethylene glycol, which makes it last longer in the body. This allows for less frequent dosing and more stable treatment. Pegylated interferon boosts the immune response, helping the body to control or eliminate disease-causing agents more effectively.
