Drug induced aseptic meningitis caused by intravenous immunoglobulin therapy.

Drug induced aseptic meningitis (DIAM) is an uncommon condition that can mimic infective conditions. DIAM has been recognized with various treatments including non-steroidal anti-inflammatory drugs, monoclonal antibodies and some antibiotics. We report a patient presenting with aseptic meningitis forty-eight hours after commencing a course of intravenous immunoglobulin (IVIG) treatment. It is important that physicians prescribing this medication are aware of this rare complication so the diagnosis can be made quickly and the patient is not exposed to unnecessary treatments.
