Did you know that more than 500 medicines contain acetaminophen, the active ingredient in TYLENOL® products?

Medicines like pain relievers, sleep aids, decongestants, and even prescriptions may contain the same ingredients. So it’s important to read the labels and take ONLY 1 medicine containing acetaminophen at a time. Why?

Taking more than one increases your chances of taking too much (more than 4,000 mg in 24 hours), which could harm your liver. Four thousand milligrams in 24 hours is the maximum dose of acetaminophen.

To help ensure you’re using acetaminophen safely, download and print this dosing chart and keep it wherever you store your medicines. For more information on using "over-the-counter (OTC)" pain medicines safely, click here
