Energy caffeinated beverages are composed mainly of caffeine, carbohydrates and dietary supplements. Although manufacturers claim that these drinks are safe and many consumers perceive that also, there is concern about the possibility that adverse events may occur with their consumption. This led us to review the literature with emphasis on the cardiovascular and neurological risks. It was found that the major health complaints (headache, sleep disorders, irritation and fatigue) were more frequent in consumers than in non-consumers.

Emergency room visits motivated by the use of energy drinks were more frequent when there was co-ingestion of ethanol and other drugs. The main cause of cardiovascular emergency consultation was arrhythmia and the neurological one, seizure. The evidence found was of poor quality, which prevented establishing a causal link between the consumption of these drinks and such risks. On the other hand, interpretation of the toxicity of these preparations is complicated because several variables should considered such as dose, individual sensibility, consumption habits, smoking, and co-ingestion of other substances, etc., in order to assess their real risk. Despite this, concomitant consumption of these beverages and ethanol seems to be a risk factor for toxicity.
