Recurrent injection site reactions from interferon beta 1-b.
Recombinant human interferon beta-1b is an immune-modulatory drug used for a variety of conditions including multiple sclerosis (MS). Skin reactions to therapeutic use of injectable interferon beta-lb are relatively common, including injection site reactions and exacerbation of underlying skin disease. Injection site reactions are seen much more frequently in females. We discuss a case of prolonged susceptibility to injection site reaction with over a decade of use of interferon beta 1-b for MS. Given the prevalence of such reactions, the dermatologist should be aware of the phenomenon and that it frequently does not necessitate discontinuation of therapy.
