Abstract
The case of a 17-year-old girl with a history of headache, blurred vision, confusion, ataxia and syncope is presented. On admission, she had already recovered except for a slurring of speech. Her urine was found to be green. Screening for illegal drugs was negative, but gas chromatography with subsequent mass spectroscopy (GC–MS) revealed an extremely high concentration of flupirtine.
