Aseptic meningitis is meningitis with negative bacterial cultures. Overall, viral infections are the most common etiology, however medications can also cause this illness.
Well known causes of aseptic meningitis include: antimicrobials (particularly sulfamethoxazole/trimethoprim), NSAIDS, antivirals (valacyclovir), and antiepileptics.
Recently an abstract was published that suggests that patients on levetiracetam have a higher risk of developing aseptic meningitis than those on topiramate and gabapentin. Lamotrigine has also been implicated, but appears to have a lower risk than levetiracetam, topiramate and gabapentin.
