Drug-induced aseptic meningitis should be included in thedifferential diagnosis of viral/aseptic meningitis. Cliniciansshould use historical clues in patients presenting with signs andsymptoms of viral meningitis to aid in the differentiation ofdrug-induced aseptic meningitis from other causes of asepticmeningitis. Viruses are the most common cause of asepticmeningitis, with enteroviruses being the most common amongviruses in cases presenting as aseptic meningitis. Ibuprofen iscurrently the most common cause of drug-induced asepticmeningitis. Drug-induced aseptic meningitis is a benign conditionwithout long-term sequelae. The diagnosis of druginducedaseptic meningitis is made by establishing a causalrelationship between the use of the drug and the onset of signsand symptoms, supported by negative tests for infectiouscauses of symptoms and rapidity of resolution after the drugis discontinued.
