Know Concentration Before Giving Acetaminophen to Infants
Overdosing Has Been a Risk An April 2011
Report from FDA’s Center for Drug Evaluation and Research (CDER) found that confusion caused by the different concentrations of liquid acetaminophen for infants and children was leading to overdoses that made infants seriously ill, with some dying from liver failure. So to avoid dosing errors, some manufacturers voluntarily changed the liquid acetaminophen marketed for infants from 80 mg per 0.8mL or 80 mg per 1 mL to be the same concentration as the liquid acetaminophen marketed for children—160 mg per 5mL.
This less concentrated liquid acetaminophen marketed for infants now has new dosing directions and may have a new dosing device in the box, such as an oral syringe. But this is a voluntary change and some of the older, stronger concentrations of acetaminophen marketed for infants are still available and may remain available.

Tylenol and Ibuprofen Linked to Dangerous Skin Disorder
SJS Submitted by Christina Anthony on Sun, 01/15/2012 - 19:45
“A link has been made between acetaminophen and the rare, allergic, sometimes fatal skin disorder Stevens-Johnson Syndrome (SJS).”
(1) “Acetaminophen may substantially increase the risk of SJS/TEN (Toxic Epidermal Necrolysis) in children.”
2) “Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two rare but life-threatening skin reactions.”
(3) Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are severe allergic reactions that have been linked to both acetaminophen and ibuprofen.
These reactions are rare but extremely severe and even life threatening. If these reactions are not treated immediately, they are more likely to be fatal. SJS is a disorder of the skin, mucous membranes, and organs.
Untreated and severe cases can progress to TEN which often results in sepsis and death. Symptom recognition is the first line of defense and can prevent progression and even more severe medical conditions.
“Stevens-Johnson Syndrome is characterized by a rash and blisters on the skin and mucous membranes. As it progresses, it can result in shedding of the skin, which can open up the body to serious infection. The affect on the skin occurs after a flu-like illness, during which the patient has a fever, body aches, sore throat, cough, and fever.”
(1) Symptoms include: · A skin rash, which may have the appearance of a bull's eye type target · Painful blisters on two or more mucosal surfaces, such as a child's eyes, mouth, nose, ear, and anogenital area, which can lead to ulceration and hemorrhagic crusting
· Eye redness and swelling
· Flu like symptoms, including a persistent fever
Other studies have linked ibuprofen to acute vanishing bile duct syndrome in children. This liver disorder has occurred, even in absence of overdose, as a result of an allergic reaction to the medication.
Although not common, allergic reactions to acetaminophen and ibuprofen in children are very severe and painful. Their use in children should be taken very seriously and children should be observed closely when taking these basic over-the-counter substances.
The effects of an allergic reaction can be minimized with immediate medical attention; however, without immediate medical attention these allergic reactions will progress and can often lead to permanent damage or even death.
liver injury related to the use of acetaminophen

June 29-30, 2009: Joint Meeting of the Drug Safety and Risk Management Advisory Committee with the Anesthetic and Life Support Drugs Advisory Committee and the Nonprescription Drugs Advisory Committee:
Agenda The primary topic area for discussion is how to address the public health problem of liver injury related to the use of acetaminophen in both over-the-counter (OTC) and prescription (RX) products. FDA recognizes that acetaminophen is an important drug used to treat pain and fever in both settings and is not seeking to remove it from the market. The risk of developing liver injury to the individual patient who uses the drug according to directions is very low.
However, acetaminophen containing products are used extensively making the absolute number of liver injury cases a public health concern.
More complete information about the topics on which FDA will seek public input will be available by or around May 22, 2009 at the 2009 Meeting Materials web page, click on the year 2009 and scroll down to the appropriate advisory committee link.

Background Acetaminophen is one of the most commonly used drugs in the United States, yet it is also an important cause of serious liver injury. Acetaminophen is the generic name of a drug found in many common brand name over-the-counter (OTC) products, such as Tylenol, and Prescription (Rx) products, such as Vicodin and Percocet.
Acetaminophen is an important drug, and its effectiveness in relieving pain and fever is widely known. Unlike other commonly used drugs to reduce pain and fever (e.g., nonsteroidal antinflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and naproxen), at recommended doses acetaminophen does not cause adverse effects, such as stomach discomfort and bleeding, and acetaminophen is considered safe when used according to the directions on its OTC or Rx labeling.
However, taking more than the recommended amount can cause liver damage, ranging from abnormalities in liver function blood tests, to acute liver failure, and even death.
Many cases of overdose are caused by patients inadvertently taking more than the recommended dose (i.e., 4 grams a day) of a particular product, or by taking more than one product containing acetaminophen (e.g., an OTC product and an Rx drug containing acetaminophen).

Extreme Acetaminophen Reaction:
Woman Takes Pill, Loses Skin "
The upper layer of the skin is attacked. It's very serious. You look at yourself, you look terrible, you're at risk of infection, you're at risk of dying." This is what happened to 19-year-old Eva Uhlin.
Five years ago, she became ill on a vacation trip to her native Sweden. When she returned home, she was told she had a fever and took acetaminophen to help relieve the symptoms.
The next morning, her entire face and body were covered in severe, disfiguring blisters.
Acetaminophen, known as paracetamol in parts of Europe, is one of the most commonly-used analgesics in the world...
