Pegylated interferon alpha (PEG-IFN-alpha) is a formulation of recombinant human interferon conjugated with polyethylene-glycol. This preparation has a long half-life (compared with conventional IFN), which allows for once-weekly injection. Elimination half-life of PEG-IFN-alpha 2b is 22-60 hours (average, 35-40 hours). We report the development of a local necrotizing reaction complicating subcutaneous injection of PEG-IFN in a patient with hepatitis C. This case enhances the need of careful training in drug reconstitution and self injection, with as much variation as possible of the injection site.

Abstract
Pegylated interferon alpha (PEG-IFN-alpha) is a formulation of recombinant human interferon conjugated with polyethylene-glycol. This preparation has a long half-life (compared with conventional IFN), which allows for once-weekly injection. Elimination half-life of PEG-IFN-alpha 2b is 22-60 hours (average, 35-40 hours). We report the development of a local necrotizing reaction complicating subcutaneous injection of PEG-IFN in a patient with hepatitis C. This case enhances the need of careful training in drug reconstitution and self injection, with as much variation as possible of the injection site.
