Drug-induced aseptic meningitis. Diagnosis leads to quick resolution.

Drug-induced aseptic meningitis is a syndrome that should be considered in the differential diagnosis of acute and recurrent aseptic meningitis. It has been observed in all age-groups and can occur following the use of a wide spectrum of pharmaceutical agents. Presumptive diagnosis is made by demonstrating the resolution of symptoms after drug withdrawal, and definitive diagnosis is made by conducting a drug rechallenge. Fortunately, the syndrome is usually benign and resolves quickly following drug cessation.
