Common questions about Infergen (interferon alfacon-1)
Infergen (interferon alfacon-1) is a biologic medication used for the treatment of chronic (long-term) hepatitis C infection. This medication is a man-made protein called interferon. Interferons work by attaching to infected and nearby cells in the body. Then, they signal these cells to produce proteins that can prevent the virus from growing. Infergen (interferon alfacon-1) works by specifically targeting hepatitis C viruses and stopping their growth.
No, Infergen (interferon alfacon-1) has been discontinued as of 2013 and is no longer available in the United States.

There are many different factors that a provider must consider in choosing the right hepatitis C medication for you, such as the type of virus, your medical history, and the presence of any liver problems. An alternative interferon medication for hepatitis C is Pegasys (peginterferon alfa-2a), which is typically injected under the skin once weekly. Additionally, hepatitis C medications called direct-acting antiviral therapies (DAATs) are available that are taken by mouth. DAATs include Harvoni (ledipasvir / sofosbuvir), Epclusa (sofosbuvir / velpatasvir), and Mavyret (glecaprevir / pibrentasvir). These medications have a 95% success rate in curing people with hepatitis C, but they might not be right for everyone. Talk with your provider to determine which hepatitis C treatment is best for you.
