Testing for Acetaminophen Toxicity

New Testing for Acetaminophen Overdose

Acetaminophen toxicity is the leading cause of liver failure in the United
States, according to the Center for Disease Control. Acetaminophen can be
found in pain relieving drugs and is safe if used at the recommended dosage.
However, when misused with alcohol or taken in excess it can lead to liver
failure and even death.

Currently acetaminophen toxicity is determined by taking a blood sample of
an individual and measuring for elevated levels of acetaminophen in the
blood. This must be done within 24 hours of a suspected overdose, due to
the fact that acetaminophen is only present for 24 hours after a large
overdose. In the past when patients were admitted in the hospital for liver
damage with undetermined causes, leaving doctors baffled to the cause of
the liver damage.

According to the University of Arkansas for Medical Sciences, researchers
have developed a more effective diagnostic test for acetaminophen
poisoning. The test relies on protein markers found in the blood that can
detect acetaminophen poisoning effectively to determine whether the liver
damage is related to acetaminophen.
A study conducted by Jack A. Hinson, Ph.D., a professor in the UAMS
Department of Pharmacology and Toxicology, discovered that out of 64
individuals who had undetermined causes of liver damage, 8 were found to
have had acetaminophen overdose as the cause. The protein adduct test is
effective in helping make better diagnoses and also in helping improve and
educate to prevent future incidences of acetaminophen overdoses

Acetaminophen Toxicity

October 8, 2008 at 3:13 am · Filed under Uncategorized ·Tagged

When acetaminophen is used in the correct doses and under the right circumstances, it is considered very useful and safe. However, people accidentally overdose themselves when combining it with other medications that contain acetaminophen in them. Heavy drinkers who mix acetaminophen with alcohol or people who consume less food than necessary are at risk for acetaminophen toxicity. Acetaminophen toxicity occurs when acetaminophen is not processed quickly enough. Therefore, too much acetaminophen is left in the blood and filters through the liver causing damage. This can lead to liver damage, liver malfunction, and/or death!

Why is this a “hot” topic?

The public is unaware of how common acetaminophen is found in over-the-counter drugs. About 100 deaths per year and last year alone, 56,000 emergency room visits are due to acetaminophen overdose, as noted on Tylenoldanger.com. According to the National Institute of Health and the Center for Disease Control, acetaminophen toxicity is the leading cause of acute liver failure in Americans.

Why should we educate ourselves?

First, acetaminophen is found in more than 600 over-the-counter and generic drugs. Therefore, the combination of any of these drugs can easily cause acetaminophen toxcity without the consumer knowing. Second, the label on the bottle does not warn consumers of the possible dangers associated with high doses, long term usage, and combining drugs containing acetaminophen.

Tylenoldanger.com stated that the FDA has proposed to changing the warning label from “If you consume 3 or more alcoholic drinks every day, ask your doctor whether you should take acetaminophen or other pain relievers/fever reducers. Acetaminophen may cause liver damage.” to “The risk of liver damage increases if you have three or more alcoholic drinks while using acetaminophen.” This would be done in efforts to warn consumers of the risks involved when combining acetaminophen and alcohol.

Treatment and Prevention of Acetaminophen Toxicity:

To prevent incidents of overdose, we should always read the labels of all the medications we are taking. We should make sure not to combine Tylenol with more than three alcoholic drinks in a day.

When acetaminophen toxicity is unrelated to alcohol, the drug acetylcysteine is used for treatment. It can be used intravenously or more commonly through a nasogastric tube.

Acetaminophen Toxicity 101

September 12, 2008 at 4:22 am · Filed under Uncategorized

Acetaminophen is one the most common and frequently used OTC drugs, known as
Tylenol. It is also present other medications like anacin-3, liquiporin, panadol, tempra,
and various other cold/flu medications. So, toxicity can easily occur when combining
Tylenol with such medications or overdosing it, because people usually do not read the
labels carefully and are unaware that acetaminophen in present in many other
medications. Acetaminophen overdose can lead to serious consequences like liver
damage and death.

Regulated by the FDA
FDA is concerned about the incidents of acetaminophen overdose in the recent years and
placed regulations on companies to place labels about acetaminophen content in all
medications.
Dr. William Lee of Texas Southern Medical Center in Dallas, in his survey tracked 300
cases of acute liver failure at 22 hospitals to which 38% was linked to acetaminophen
overdose.

Causes

A. Taking acetaminophen in combination with more than 3 alcoholic drinks a day.

B. Varying dosing schedules and formulations of recommended drug in infants and         
   children.

 C. Combining it with other medications that contain acetaminophen as one of their drugs.

Signs and Symptoms:
Initial symptoms may be flu-like, so doctors may not be prompt for overdose treatment.
Other symptoms include -sudden fever, nausea and vomiting, abdominal pain, diarrhea,
irritability, jaundice, sweating, coma, and/or convulsions.

Treatment

Symptoms do not occur until 12 or more hours after acetaminophen consumption.:
Require immediate assisteance to the emergency, within 8 hours.

Prognosis
If not treated, overdose can lead to LIVER FAILURE and DEATH.
