KEILAR: Next time you buy a bottle of Tylenol, you may notice a new warning label on that bottle.</s>BLACKWELL: Yes, the maker, Johnson & Johnson made the change with the aim of reducing the number of accidental overdoses from this popular reliever. Our senior medical correspondent Elizabeth Cohen has more -- Elizabeth.</s>ELIZABETH COHEN, CNN SENIOR MEDICAL CORRESPONDENT: Brianna, Victor, these warnings are big and they are bold. What the cap is going to say is "Contains acetaminophen", that's the active ingredient in Tylenol and always read the label. Now they're doing this because acetaminophen overdoses have become all too common. In this country each year there are 56,000 visits to the emergency room because of acetaminophen overdoses and 500 deaths. Now, some of those deaths are intentional -- people were trying to hurt themselves and many of them are not. Now of many of these overdoses are not actually just on Tylenol. Here's what ends up happening. Let's say for example you have surgery and your doctor prescribes Percocet. Well, Percocet has acetaminophen in it which a lot of people don't know. So you take the Percocet -- maybe it's not working for you. You want to take something in addition so you take Tylenol. Well, that's more acetaminophen. And then let's say at night, you're having trouble sleeping, you want a little bit of help and then you take some Nyquil. Well, Nyquil has acetaminophen in it. So you've just gotten a triple dose of acetaminophen. If you do that for about a week you run the risk of going into acute kidney failure. And so they're hoping that with this new label, people will know to look at all the acetaminophen that they are taking, not just the acetaminophen that's in Tylenol -- Brianna, Victor.</s>KEILAR: Elizabeth Cohen, senior medical correspondent -- thank you.
