Earlier this month, Clark informed you about the dangers of liver failure and death associated with unintended large doses of acetaminophen.

According to The Boston Globe, a new FDA report calls for more stringent label warnings on acetaminophen products -- the most popular of which is Tylenol.

The real danger comes when you have flu symptoms and take a cold remedy that contains acetaminophen, plus a couple of Tylenol in addition to that. The combo can be truly deadly. In fact, acetaminophen is the leading cause of liver failure.

Of course, you can always protect yourself by simply taking ibuprofen or aspirin instead. But if those options don't appeal to you, Clark has another suggestion.

A traditional dose of Tylenol is 325 mg. For marketing reasons, however, almost all acetaminophen is 500 mg per pill and it's marketed as "extra strength." So you might want to consider switching back to regular strength tablets.

And if you have an inventory of "extra strength" tablets in your medicine cabinet, be sure to only take one pill at a time instead of two.
