Modafinil is a non-amphetamine stimulant that is prescribed for narcolepsy-associated sleepiness as well as reported off-licence uses among university students looking to improve wakefulness and focus. There is limited information in the medical literature about supratherapeutic modafinil dosage, symptomatology and management of overdose. We report a case of a healthy 32-year-old man who was found unconscious, having vomited, with an empty modafinil blister strip. At the emergency department, he presented with reduced Glasgow Coma Scale and prolonged episodes of vomiting. This acute presentation was conservatively managed in the intensive care unit. Antibiotics were also given for a suspected aspiration pneumonia. CT of the head showed cerebral oedema and biochemistry investigations revealed hyponatraemia. Result aetiology was unclear, however, it has been theorised to be secondary to a sizeable modafinil overdose.
