Acetaminophen/Tylenol® can Cause
Liver Damage & Death Due to Glutathione Depletion

The purpose of this article is to explain how ingestion of the popular pain-relieving medication acetaminophen depletes glutathione levels in the liver, causing damage that could result in death.

Every year, thousands of people, including children, become ill, and hundreds die from ingesting too much of the over-the-counter medication, Acetaminophen (initially marketed in 1959 brand name Tylenol®). The pain-reliever Acetaminophen undergoes detoxification for excretion in the liver. Most people don’t realize that this process rapidly depletes glutathione in the liver, resulting in liver damage that can lead to death.

Acetaminophen is classified as a non-prescription analgesic. Its primary uses are for the relief of pain and to reduce fever. More than 600 drugs contain Acetaminophen, which makes Acetaminophen the most commonly consumed drug ingredient in America. Acetaminophen is also an ingredient in many widely prescribed prescription pain medications.

How Dangerous is Acetaminophen? Acetaminophen is generally safe when taken at the recommended dosage levels. However, acetaminophen overdose is the leading cause for calls to Poison Control Centers (over 100,000/year). It accounts for more than 56,000 emergency room visits, 2,600 hospitalizations, and an estimated 500 deaths per year due to acute liver failure.i

Suicide Attempts:Acetaminophen is the most common drug used in intentional overdoses for attempted suicide in the United States.ii According to the CDC, the rate of suicide among teens between the ages of 10 to 24 increased by nearly 60% between 2007 and 2018.iii Unfortunately, because Acetaminophen is inexpensive and easy to purchase, Acetaminophen has become the most frequently chosen drug for attempted suicide among adolescents.iv

Liver Transplants & Acute Liver Failure: Acetaminophen toxicity has replaced viral hepatitis as the most common cause of acute liver failure in the United States and is the second most common cause of liver transplants in the United States. Acetaminophen toxicity is also common in children, although adults account for the most severe and fatal cases.v

The importance of glutathione: Over 100,000 scientific studies have been published regarding the biological effects of glutathione. It is a critical regulator of antioxidant activity, detoxification, and immune function. Consequently, glutathione regulates the health of every cell in the body.

Low glutathione levels are associated with virtually all chronic lifestyle-related diseases.vi,vii Conversely, studies in numerous animal species have shown that boosting glutathione levels results in better health and increased longevity. Studies in humans indicate that higher glutathione levels are associated with better health and increased longevity. For example, glutathione levels in centenarians are similar to the levels of young adults.viii

Glutathione’s importance to health is so definitive. It has resulted in the proposal of the ‘Glutathione Deficiency Hypothesis,’ which suggests that glutathione deficiency is a primary cause of biological aging.ix Consequently, glutathione levels are now recognized as a reliable biomarker of aging.x

Because glutathione is so critical to the health of every cell in the body, taking drugs that contain Acetaminophen and the resulting depletion of glutathione can cause serious health problems for people of all ages. Medicines that contain Acetaminophen are reviewed in the following section.

ACETAMINOPHEN-CONTAINING DRUGS

Infant Pain Relievers: Concentrated acetaminophen-containing drops and/or liquid are commonly used to ease the pain and discomfort associated with teething, which generally begins when infants are about six months old. Discomfort for each tooth can be from 2 to 7 days, and teething in an ongoing process can take from 6 to 24 months. Thus, some infants are being dosed with Acetaminophen multiple times daily as parents give their child acetaminophen drops or rub the liquid directly onto their gums to alleviate teething discomfort.

Children’s Pain & Fever Relief: According to a consumer healthcare report, Tylenol® is the #1 pediatrician recommended brand to relieve pain and fever in children.xi These products and their generic equivalents are available in chewable tablets and liquid suspension.

Adult OTC Medications: In addition to OTC acetaminophen-containing pain medications, there are several other classes of OTC medications that contain Acetaminophen, such as:

  1. Headache medicines such as Excedrin and Anacin contain Acetaminophen as the main active ingredient.
  2. Cold and flu treatments in which Acetaminophen is combined with decongestants, antihistamines, and cough suppressants. Examples are DayQuil, Alka-Seltzer Plus Cold and Sinus, Robitussin Cold, Cough and Flu, Sudafed PE Cold and Cough, and Triaminic Cold and Fever.
  3. Meds for premenstrual relief from headaches and muscle cramps such as Pamprin, Premesyn PMS, and Midol PMS.
  4. Nighttime formulas. Acetaminophen is not a sedative, but it is often combined with drugs that do promote sleep. Examples are NyQuil and Excedrin PM.

Prescription Pain Relievers.

  1. Hydrocodone/acetaminophen (Brand names Vicodin, Norco, Lortab, Lorcet & others; available as tablets, solution, and elixir). According to a recent survey, hydrocodone with acetaminophen pain medications were the 10th most commonly prescribed class of drugs in the United States and the prescribed pain medications in America.xii
  2. Oxycodone with Acetaminophen (Brand names Percocet, Tylox, Roxicet, Endocet & others; available as tablets and oral solution. Oxycodone is a more potent painkiller than hydrocodone, and chronic use or misuse of oxycodone/acetaminophen is a contributing factor in the current opioid epidemic.

Other Factors That Deplete Glutathione: Processed foods and nutrient-deficient diets can contribute to glutathione depletion—many environmental toxins such as lead and mercury, agricultural pesticides and herbicides, dioxin, and PCBs. Smoking causes a great deal of oxidative stress, which depletes glutathione. Alcohol is detoxified by glutathione in the liver. Studies show that chronic and acute alcohol ingestion can severely decline glutathione in the liver, heart, kidney, and brain.xiii

How To Protect Yourself: Products under the brand name Reg’Activ® contain a unique strain of probiotic bacteria named Lactobacillus fermentum ME-3 that synthesizes glutathione. Studies have shown that the daily use of Lactobacillus fermentum ME-3 is a very effective way to boost glutathione levels. In human clinical trials, individuals ingesting ME-3 for two weeks gained a remarkable 49% increase in the ratio between reduced to oxidized glutathione.xiv

Boosting glutathione levels by regularly taking one of the Reg’Activ formulations is one of the most important proactive steps people can take to enhance their health. In addition to supporting liver detoxification, boosting glutathione levels will also provide additional antioxidant protection, increase protection against viruses and toxins from mold exposure, and provide general support for the immune system.
