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-1b 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.
