Abnormalities of hair growth such as eyelash hypertrichosis1 and telogen effluvium2 may result from use of interferon alfa (IFN-α). In addition, localized injection site reactions may include vasculitis and cutaneous necrosis.3 We report subcutaneous injection site alopecia in 3 patients receiving interferon alfa-2b for chronic hepatitis C as part of an institutional review board–approved treatment protocol. To our knowledge, this side effect of interferon alfa-2b is previously unreported.
