A variety of injection-site reactions (ISRs) have been reported, including pain
and erythema, lipoatrophy, abscesses
and infections, necrosis, rash, swelling,
and lumps. In order to appropriately distinguish between normal and abnormal reactions and to determine when further intervention is required, nurses involved in the care of patients with MS should be knowledgeable about the potential ISRs associated with DMTs.
