PEGASYS is a form of interferon treatment—a substance that has been shown to help fight hepatitis C. It is used alone or in combination with COPEGUS® (Ribavirin, USP) in adults with compensated liver disease not previously treated with interferon alpha.
Hepatitis C treatment with PEGASYS provides a response within 24 or 48
weeks (depending on the type of your hepatitis C virus).
Several years ago, interferon needed to be taken 3 times per week. But since then, researchers have found something better. By attaching a substance called polyethylene glycol (PEG) to interferon alfa-2a, they made interferon last longer in the body and produced PEGASYS: a once-weekly medication. Now PEGASYS is the most prescribed hepatitis C medication of its kind!
Tens of thousands of hepatitis C patients were treated in PEGASYS clinical trials all over the world, and scientific studies of more uses of PEGASYS continue today.
I want more details about PEGASYS, interferon, and the pegylation process.
I want to go to the next topic: What is COPEGUS?.
