Teens are being admitted to hospital emergency rooms after overdosing on energy drinks.
The poisons hotline has received a four-fold increase in calls relating to the high-sugar drinks.
Experts say teenagers are being "poisoned" by the drinks and suffering hallucinations, seizures and cardiac problems.
Research by the Poisons Information Centre shows the average age of those becoming ill is 17, but youths as young as 15 have also overdosed.
AMA Victoria vice-president Dr Stephen Parnis said people did not realise the serious health repercussions of energy drinks - some of which had the same amount of caffeine as 10 or 20 cups of coffee.
"Warning labels would be the very bare minimum that should be done," he said.
"I would think that preventing sales of these drinks to people under 18 is something that we need to look at very seriously.
"Poisoning is not too strong a word to use for the effects of these drinks on some people.
Dr Parnis said some teens had an energy drink as a substitute for a bowl of cereal for breakfast, and others used them as a stimulant for study sessions.
Mr Robinson said the brands that had caused the most problems in young people had been Mother, Red Bull, V, Wicked Energy Drink and Xocai.
He said some young people could be using the drinks to get high or a buzz.
"Particularly in adolescents it's hard to tell if they're deliberately trying to get hyped up or if it's an accident," he said.
He agreed the cans should have health warnings.
