Seizures and hyponatremia after excessive intake of diet coke

Eur J Emerg Med. 2008 Feb;15(1):51. doi: 10.1097/MEJ.0b013e3282703645.


We describe a case of epileptic seizures after a massive intake of diet coke. Apart from the hyponatremia due to water intoxication the convulsions can be potentiated by the high dose of caffeine and aspartame from the diet coke. To our knowledge this is the first report of seizures due to excessive diet coke intake.
