Drug-induced aseptic meningitis is a rare adverse effect of some drugs. We report a patient with four episodes of meningitis caused by ibuprofen. In all episodes the patient had taken ibuprofen for pain, and subsequently developed fever and cerebrovascular symptoms. Drug-induced meningitis cannot be distinguished from meningitis caused by other agents. Diagnosis is therefore based on close association between drug administration and onset of symptoms, as well as negative microbiology tests results, especially if previous episodes of drug-induced meningitis have occurred.
