止痛药醋胺酚（Acetaminophen)对健康有危害性
Health risks (摘录自CNN Report by Holly Yan)
"Acetaminophen overdose is one of the most common poisonings worldwide," according to the National Institutes of Health.
Taking too much of this pain reliever can lead to liver failure or death.
The FDA has set the recommended maximum for adults at 4,000 milligrams per day. It's easier to reach this limit than you might think; one gel tablet of Extra Strength Tylenol, for example, contains 500 mg.

Consumers should not take more than the prescribed dose of any medication that contains acetaminophen, according to the FDA, and should avoid taking more than one acetaminophen product at a time. Drinking alcohol while taking acetaminophen also puts you at risk.
To find out if your medications contain acetaminophen, read the drug label or the list of ingredients in the patient information leaflet that came with your prescription. Look for the word "acetaminophen" or the letters "APAP," an abbreviation sometimes used for the drug. If you are still unsure, contact your doctor or pharmacist.
Acetaminophen may also cause serious skin reactions in some people. According to the FDA, the skin reactions are rare but can be deadly. These conditions can cause blisters, serious rashes, reddening of the skin and the detachment of the upper surface of the skin, the epidermis.
