Energy Drinks and Seizures

Energy drinks usually supply energy through large amounts of caffeine and sugar. Consumers can drink one energy drink a day without worry, but drinking more than 400mg of caffeine may be dangerous. Seizures are a possible side effect of consuming too much caffeine through energy drinks.

Fast Facts:

  • Some believe that seizures caused by energy drinks are due to the crash that follows the energy high.
  • Reports of energy drink induced seizures are rare.
  • There is no danger of overcaffeination in one drink, but more than one drink can lead to adverse side effects.
  • Other adverse side effects of consuming too much caffeine through energy drinks include nervousness, irritability, frequent urination, and arrhythmia.
