Eosinophilic Meningitis and Ibuprofen Therapy

We describe eosinophilic meningitis associated with ibuprofen therapy in a young woman who had no evidence of underlying illness. Discontinuation of ibuprofen was followed by prompt resolution of symptoms and disappearance of eosinophils from the CSF. Ibuprofen has been implicated previously in only five cases of aseptic meningitis--all in patients with an underlying autoimmune disease. No drug has been implicated previously as a cause of eosinophilic meningitis to our knowledge.
