Ever wondered what would happen if you overdosed on Red Bull? Answer: your heart could stop ticking. I am not kidding.Australian man, Matthew Penbross (28), found that out recently after drinking eight of the super-highly caffeinated beverages during a five hour period. I guess eight is his unlucky number, because after downing that last one he collapsed. An ambulance was called and the first aid crew found Penbross having a heart attack. Realizing his heart had stopped, they had to use a defibrillator to get his heart pumping again.
The obvious question: why was he drinking so much darn Red Bull?? Answer: he was competing in a motocross (motorcycle racing) event and wanted to get his adrenalin pumping. "It was to get a bit of a buzz and keep down my reaction time," says Penbross.
Penbross has gone public since his unfortunate RB-related incident. He says the product should sport a decent warning label. He says that current labels, which warn against consuming more than two cans per day, are inadequate. I guess a brush with death is more of a jolt than he was looking for...
Here's the thing: Penbross admits that prior to the heart attack he'd routinely drink four cans of Red Bull daily, which is twice the recommended maximum. Not only that: he also admits he continued to drink it even after experiencing chest pains. C'mon! I have no sympathy for the guy.
By Food and Drug Administration (FDA) estimates, one million adults and two million children have prescriptions filled each month to treat attention deficit hyperactivity disorder (ADHD). The drugs are stimulants and as such, pose potential risk for heart problems, stunted growth, seizures, vision problems and psychotic behavior.
