OTC Pain Relief: Understanding Acetaminophen. Youâve probably taken acetaminophen at one time or another for fever or pain relief. You may know acetaminophen as the active ingredient in Tylenol and many other over-the-counter (OTC) products, including cold medications. When used as directed, taking acetaminophen is generally safe and effective. But it can be harmful if itâs not taken correctly.
Tylenol contains acetaminophen. The maximum daily dose of acetaminophen must not exceed 4000 mg ('daily' means 24 hours). It is not recommended to take more than 1000 mg of acetaminophen at a time. The interval between 1000 mg doses should be about 6 hours. 500 mg doses can be taken more frequently, e.g. every four hours. Each Tylenol 500 gelcap, etc, contains 500 mg of pure acetaminophen.
