What doesn't kill you make you stronger

Dr. Rod Lim at the London Health Sciences Centre suggests the labels may be useful to prevent accidental overdoses in specific instances. For example, people who take two pills every four hours could easily overdose on Extra Strength Tylenol.

"The problem is they're used to taking two pills every four hours but they'll exceed the maximum daily dose within 16 hours," he tells CBC.

Acetaminophen can be found in other products such as Nyquil, Excedrin, and Sudafed.

The following details appears on the box of the Tylenol Extra Strength "Do not take more than the maximum daily does. Overdose may result in severe or possibly fatal liver damage."

The pain doesn't kill, so putting up with it trumps the side effects of the soothing pain medication.
