Health professionals in Australia called for health warnings on caffeine-loaded energy drinks.

Over the seven years to 2010, 297 calls for assistance were recorded with at least 128 people hospitalised with symptoms including heart palpitations, agitation and stomach upsets.
Of these, 20 people had more serious issues, such as seizures and hallucinations.
The study, published in the Medical Journal of Australia on Monday, said the average person affected was 17 years old and that they often mixed energy drinks with alcohol.
"Our study demonstrates the extent of the growing problem in Australia with energy drink consumption and toxicity, particularly among adolescents," the study's authors wrote.
"Given the clear evidence of toxicity and the growing number of hospitalisations associated with consumption of energy drinks... health authorities should increase awareness of the problem, improve package labelling and regulate caffeine content."

"Things to look at would be... how much caffeine do these drinks contain, how many can you buy at once, what age should you be when you buy them, should there be an age limit to being sold the drinks," he said.
