Be on the defensive for acetaminophen buildup

When seeking quick pain relief, people should not overuse acetaminophen as a cure-all, UT Southwestern Medical Center liver disease experts warn.

From Super Bowl parties to flu-season aches, many people reach for acetaminophen in its many forms – headache relief, sleep aids, cold and flu remedies, even some prescription painkillers – not realizing how quickly the medication can add up. “

It is easy to lose track of how much combined acetaminophen you're consuming when taking combinations of medicines, particularly for different ailments such as arthritis and perhaps a cold,” says Dr. William Lee, director of the Clinical Center for Liver Diseases at UT Southwestern.  Failing to identify the different names for acetaminophen, such as 'APAP' or just not reading labels can be deadly, since acetaminophen is present in many types of pain pills, both prescription and over the counter, as well as in cold and flu medications. 

Too much acetaminophen in the system at one time or over an extended period can cause serious liver damage, liver failure and even death. More than 200 people in the U.S. die annually of accidental acetaminophen poisoning and another 15,000 end up in the emergency rooms from unknowingly taking too much. The average adult should avoid more than 3-4,000 milligrams of acetaminophen per day, the equivalent of eight extra-strength tablets, and no more than 2,000 mg to 3,000 mg for those with liver problems like hepatitis or for those who drink regularly. Alcohol consumption, Dr. Lee warns, makes acetaminophen more toxic while depleting other substances that protect against liver damage.
