A HISTORY OF LIVER DAMAGE AND THE TYLENOL® LAWSUIT
Acetaminophen is one of the most commonly used pain medications in the world. It is available over-the-counter as Tylenol®, and also as an ingredient in many prescription pain relievers. While acetaminophen is an effective treatment for pain and fever reduction, it is also toxic to the liver and one of the most common causes of drug poisoning and acute liver failure in the United States. Acetaminophen has a high risk of overdose and accounts for more than 50,000 emergency room visits each year. As a result of these complications and inadequate warnings from the manufacturers and marketers of the affected products, many people who experienced adverse side effects have filed claims in the Tylenol® lawsuit. If you have taken a medication that contains acetaminophen and experienced any complications, you may be entitled to damages. Please contact an experienced defective products attorney who can evaluate your case and help explain the timeline of litigation.
Tylenol's main ingredient, acetaminophen, has been linked to kidney problems, even when taking the recommended dosage.
WHAT IS ACETAMINOPHEN?
Acetaminophen is an analgesic pain reliever that was developed and marketed as Tylenol® in 1955 by McNeil Laboratories, which is now a subsidiary of Johnson & Johnson. Acetaminophen can also be found as an ingredient in many combination prescription pain medications such as Tylenol® with codeine, Vicodin, and Percocet, as well as many over-the-counter cold remedies such as NyQuil® and Robitussin®.
THE TYLENOL® LAWSUIT
Tylenol® has become one of the most popular over-the-counter treatments for aches, pains, and fever reduction. However, it has also been connected to serious safety concerns from bacterial contamination to package tampering. Acetaminophen can be toxic to the liver and carries a high risk of overdose. Acetaminophen accounts for more calls to U.S. poison control centers than any other drug, and is responsible for over 450 deaths annually. Additionally, over 40 percent of all acute liver failure cases in this country each year can be attributed to acetaminophen.
Many claims filed in the Tylenol® lawsuit allege that the manufacturers failed to provide the consumer with adequate warnings of the increased risk of dangerous side effects.
Many claims filed in the Tylenol® lawsuit allege that the manufacturers failed to provide the consumer with adequate warnings of the increased risk of dangerous side effects, including potentially fatal liver damage. These claims further allege that Johnson & Johnson was aware of the increased potential for complications, yet took no action to protect consumers of their products.
The individual lawsuits have been collected into a multidistrict litigation (MDL). An MDL is similar to a class action lawsuit, except that the results obtained by one party are not legally binding to the other plaintiffs. Multidistrict litigation is commonly used to establish settlement classes in complaints involving defective products.
TYLENOL® AND LIVER DAMAGE TIMELINE
Acetaminophen was discovered to have analgesic and antipyretic properties in the late nineteenth century. However, it was not prescribed or studied further until 1949 when McNeil Laboratories had defined a new product objective for an analgesic that would be different from aspirin. After learning of acetaminophen at a scientific symposium in New York, McNeil began its own extensive research into its safety and efficacy.
THE INTRODUCTION OF TYLENOL®
Tylenol® was introduced to the market in 1955 as a safe and effective treatment for pain and fever reduction in children, and it was available by prescription only. Tylenol® was an enormous success, thanks in large part to McNeil’s unique marketing strategy. The company employed a large pharmaceutical sales force that went directly to healthcare professionals and informed them of the dangerous side effects of aspirin, such as stomach irritation, gastrointestinal bleeding, and impairment of blood clotting. Following the success of their first single-ingredient acetaminophen pain reliever, McNeill Laboratories started developing additional Tylenol® products before being acquired by Johnson & Johnson in 1959.
REGULAR STRENGTH TYLENOL® FOR ADULTS
After launching several variations of the popular children’s medication, Johnson & Johnson developed a product for adults in 1961. The first regular-strength adult Tylenol® product was a tablet that contained 325 milligrams of acetaminophen, meaning that adults who took two tablets would be ingesting 650 milligrams per dose.

In 1975, Extra Strength Tylenol® was launched. These tablets contained 500 milligrams of acetaminophen each, meaning that a two-tablet dose contained 1,000 milligrams. The original maximum daily dosage of acetaminophen was established at 4,000 milligrams. However, Extra Strength Tylenol® packaging was confusingly worded and encouraged consumers to take two tablets, four to six times per day, for a total potential intake of 6,000 milligrams of acetaminophen.
FDA ADVISORY COMMITTEES AND WARNING LABELS
According to testimony from a 1977 U.S. Food and Drug Administration (FDA) Advisory Committee hearing on the safety and efficacy of Tylenol®, the first reported cases of fatal acetaminophen overdoses occurred in 1966. This committee recommended that all Tylenol® packaging carry a warning about maximum daily dosages and the risk of liver damage associated with acetaminophen. However, the manufacturer did not add a warning label about the risk until 1994, following a lawsuit filed by a patient who required a liver transplant after mixing Tylenol® with alcohol.
In 2009, the FDA issued guidelines to add overdose warnings to all packages containing acetaminophen. This regulation contains specific language that severe liver damage may occur if the user exceeds the maximum daily dosage of 4,000 milligrams, takes it with another medication that contains acetaminophen, or has three or more alcoholic drinks while taking the medication.
In 2011, the FDA announced that they had requested drug manufacturers to limit prescription medications to 325 milligrams of acetaminophen per tablet, capsule, or other dosage units. They also added a “Black Box” warning to prescription medications about the increased risk of liver damage associated with acetaminophen. However, the committee decided that over-the-counter products containing acetaminophen already had adequate warning labels. Also in 2011, Johnson & Johnson changed the recommended daily dosage from 4,000 milligrams to 3,000 milligrams of acetaminophen.
The FDA recommended that Tylenol® packaging carry a warning label about the increased risk of liver failure associated with acetaminophen.
Beginning in 2013, Johnson & Johnson added a red warning on the cap of all bottles of Tylenol® sold in the U.S. This new warning says “CONTAINS ACETAMINOPHEN” and “ALWAYS READ THE LABEL,” and is intended to protect consumers from the dangers associated with the drug.

FDA STUDIES AND ADVISORIES
- An FDA Advisory Committee met in 1977 to discuss the safety and effectiveness of acetaminophen. This committee recommended that Tylenol® packaging carry a warning label about the increased risk of liver failure associated with acetaminophen. However, a warning label was not added to packaging until 1994.
- The FDA issued guidelines about warning labels for all products that contain acetaminophen in 2009. This new label will advise consumers not to exceed the daily dosage of acetaminophen, and provide information on the increased risk of liver damage and the dangers of mixing the drug with alcohol.
- In 2011, the FDA issued a safety announcement concerning products containing acetaminophen. They advised all pharmaceutical manufacturers that make prescription medications containing acetaminophen to limit the amount to 325 milligrams per dosage unit to protect consumers from accidental or intentional overdose. Additionally, they recommended a boxed warning on all packaging that highlights the potential for liver damage when taking acetaminophen.
