Meningitis causes inflammation of the meninges and when bacteria are not the cause may be considered aseptic. Drug-induced aseptic meningitis (DIAM) can arise from the use of certain medications. The pathophysiology of DIAM is not well understood. Within the antiepileptic medication class, only lamotrigine, carbamazepine, and levetiracetam have been associated with DIAM via documented cases. Common presentation of DIAM involves fever, headache, meningismus, and mental status changes (abnormal consciousness and focal neurological deficits). Other clinical features may include neck stiffness, photophobia, nausea, vomiting, abdominal pain, bone pain, hypotension, edema (facial and optic nerve), rash, and seizures. Case reports of DIAM with varying or limited symptomology exist. Therefore, the presentation alone will not allow for a DIAM diagnosis, prompting further analysis and diagnostic exclusion.
