A healthcare provider may prescribe peginterferon alfa-2b to treat hepatitis C or malignant melanoma. This medicine comes as an injection that is given subcutaneously every week for up to one year (for hepatitis) or for up to five years (for melanoma). Many people who use this medicine will develop some type of side effect, such as muscle pain, fatigue, or headaches.
Peginterferon alfa-2b (PegIntron®, Sylatron®) is a prescription medication approved to treat hepatitis C (for PegIntron) or malignant melanoma (for Sylatron). It is given as an injection just under the skin once a week.
When used to treat melanoma, this medication is used after the cancer has been surgically removed. When used to treat hepatitis C, it is usually combined with ribavirin (Rebetol®), an oral medication taken twice a day. It works even better for hepatitis C when combined with both ribavirin and a hepatitis C protease inhibitor (like Incivek™ or Victrelis™), although such a combination is not appropriate for all individuals.
