After all, acetaminophen is found in more than 600 over-the-counter and prescription medications, the U.S. Food and Drug Administration says.
The FDA makes these recommendations on how to make sure you don't take too much acetaminophen, the active ingredient in Tylenol:
- Adults should not exceed 4,000 milligrams per day. Never take more than the recommended dose of any medication.
- Avoid taking multiple over-the-counter medications that contain acetaminophen.
- Don't take a prescription drug that contains acetaminophen along with an OTC medication that contains it.
