A sharp rise in emergency calls related to energy drinks with a high caffeine content has prompted a call for tighter regulation and compulsory health warnings.
The call, rejected by the energy drink industry, came after research by the University of Sydney and the New South Wales Poisons Information Centre found an increase in symptoms including cardiac arrhythmias, tremors, dizziness, hallucinations and stomach problems.
Published in the Medical Journal of Australia, the research also warned of even greater problems emerging with the "dangerous phenomenon" of mixing energy drinks with alcohol.
The Legislative and Governance Forum on Food Regulation, which includes Australian and New Zealand health ministers, has already agreed to a review of caffeinated energy drinks.
If the review reflects researchers' concerns the transtasman regulatory body Food Standards Australia New Zealand could be told to consider new regulations.
