. Within a week, the company pulled 31 million bottles of tablets back from retailers, making it one of the first major recalls in American history.

As a result of the crisis, all Tylenol capsules were discontinued, as were capsules of other brand names. Tamper-proof, triple-sealed safety containers were swiftly placed on the shelves of retailers 10 weeks after the withdrawal. Other manufacturers followed suit. The crisis cost the company more than $100 million. Tylenol regained 100% of the market share it had before the crisis. Seven people died. The Tylenol murderer was never found. A $100,000 reward offered by Johnson & Johnson still remains unclaimed.

Tylenol remains a top seller, controlling about 35% of the pain killer market in North America.

2010 Tylenol recall

On January 15, 2010, 20 months after first receiving consumer complaints, Johnson & Johnson announced a voluntary recall of several hundred batches of popular medicines, including Benadryl, Motrin, Rolaids, Simply Sleep, St. Joseph Aspirin and Tylenol. The recall was due to complaints of a musty smell which is suspected to be due to contamination of the packaging with the chemical 2,4,6-tribromoanisole

Dangers

Acetaminophen causes three times as many cases of liver failure as all other drugs combined,
and is the most common cause of acute liver failure in the United States,
accounting for 39% of cases. While this generally occurs through overdosing, the window of toxicity can increase at lower than toxic doses when acetaminophen is combined with alcohol, especially in heavier drinkers, or those with compromised liver function as a result of alcohol use.

Acetaminophen is metabolized in the liver, resulting in a by-product, N-acetyl-p-benzoquinone imine (NAPQI), that can damage liver cells, but is typically converted into a harmless substance by an antioxidant glutathione. However, large doses of acetaminophen overwhelms the body's supply of glutathione, resulting in destruction of the liver cells.

People who have the highest risk for Acetaminophen related kidney failure include: heavy drinkers (three or more drinks per day), elderly men, and persons with pre-existing liver or kidney damage.

A study published by the Journal of the American Medical Association in 2006 suggests problems even in healthy people taking the pain reliever as directed. Healthy adults taking maximum doses of Tylenol for two weeks had abnormal liver test results. Dr. Neil Kaplowitz of the University of Southern California, co-author of the study, said,
"I would urge the public not to exceed four grams a day. This is a drug that has a rather narrow safety window..."

According to a preliminary study mixing acetaminophen and caffeine may cause liver damage, especially in heavy caffeine drinkers. Researchers discovered that caffeine can triple the amount of, N-acetyl-p-benzoquinone imine (NAPQI), the dangerous by product which destroys liver cells. This reaction can also be caused by large doses of painkillers that combine caffeine and acetaminophen (e.g., Anacin, Excedrin & Midol). These products are often used to treat migraines and menstrual discomfort. Dr. Sid Nelson, a professor of medicinal chemistry at the University of Washington said, "Caffeine can interact with an enzyme that can form a toxic metabolite of acetaminophen in such a way that it increases the formation of that toxic metabolite".

Symptoms from an overdose of acetaminophen typically appear after 24 hours, or in some cases up to 48 hours, however immediate treatment prior to the onset of symptoms can greatly improve the outcome. The antidote to acetaminophen overdose, N-acetylcysteine (NAC), is most effective when taken within eight-hours of an overdose. Due to the delayed symptoms and the importance of immediate treatment, overdoses of acetaminophen kill about 12% of those who seek treatment. Typical symptoms range from nausea and malaise to extreme upper abdominal pain in the region of the liver.

Tylenol is only one among many popular medications containing acetaminophen, but few users realize that it is contained in hundreds of other pain relievers and cold remedies, and that combined usage has a cumulative effect. Fifteen percent of accidental overdoses involve the simultaneous use of more than one product containing acetaminophen. Products from common brands include acetaminophen: Excedrin, Midol, Theraflu, Alka-Seltzer and NyQuil, as well as prescription narcotics such as Vicodin and Percocet. Following the recommended dosages for each, but in combination can far exceed safe limits for acetaminophen intake. The manufacturers of Tylenol recommend, "You should not take two or more products that contain acetaminophen at the same time."

Link with Childhood Asthma
Dr. John McBride reported in the journal, Pediatrics, http://pediatrics.aappublications.org/content/early/2011/11/04/peds.2011-1106.full.pdf+html?sid=292aac87-0b02-4f3f-86c7-99a0bccb2314 on 1st November 2011, that Acetaminophen, marketed as Tylenol in the USA and in the UK as Paracetamol, may worsen asthma symptoms in both adults and children. He reviewed recent studies on the medication, which suggest that the drug may exacerbate asthma in children and adults who already have the condition and could even spark new cases.

One of studies McBride cites looked at 520,000 children from 122 centers in 54 countries. In a report on that data published in The Lancet in 2008, researchers found that the risk of developing asthma jumped by 60 percent in 6- to 7-year-olds who had taken acetaminophen at least once a year but less than once a month. In children who took the medication at least once a month, the risk more than tripled.

A second report using the same data was published in the American Journal of Respiratory and Critial Care Medicine in 2011. That report found that the risk of developing asthma jumped by 40 percent in 13- to 14-year olds who had taken acetaminophen at least once a year but less than once a month. In children of the same age group who took the medication at least once a month, the risk more than doubled. Other studies found acetaminophen associated with an increased risk of asthma in adults.

Advertisements

Tylenol has many different advertisement approaches. One of these advertisement campaigns focuses on “getting you back to normal”, whereas the other commercials focus on Tylenol’s current slogan, “Feel better, Tylenol”. In the “Feel better, Tylenol” commercials, Tylenol places emphasis on the importance of sleep; various people are seen sleeping in this commercial while a voiceover describes how sleep can help repair and heal the human body during times of aches and pains. In the “getting you back to normal” commercial, Tylenol places more emphasis on helping its consumers get back to their daily routines; many different people are shown first experiencing headaches and other sorts of body pain, where a voiceover then states that Tylenol Rapid Release can help rid aches and pains; the various people are then showed enjoying their everyday lives, and are seen as “back to normal”.
In an older commercial from 1986, Tylenol emphasized that it is the drug that American hospitals trust the most. In this ad, Susan Sullivan

told the consumer that Tylenol was a drug that could be trusted by Americans since many doctors also trusted it; she went on to state that doctors prescribed Tylenol four times more often than the other leading pain relieving drugs combined.
