The Truth About Acetaminophen

Updated: Sep 9, 2022

Of course, acetaminophen is the number one suggested over-the-counter (OTC) medication. Acetaminophen, commonly known as Tylenol, is a medication used to alleviate mild to moderate pain from ailments such as headaches, muscle aches, menstrual cramps, colds, sore throats, toothaches, backaches, and fevers. This may seem great, but do you know at what cost the relief comes?

Many people fail to realize that although acetaminophen may be FDA-approved, that doesn't necessarily mean it's a safe option. Acetaminophen is a pain killer linked to an increased risk of health problems when used long-term or in larger doses. Although acetaminophen is technically safer than nonsteroidal anti-inflammatory drugs (NSAIDs), there are still many risks associated with taking this specific over-the-counter medication (1).

Dangers Of Acetaminophen

Damages The Liver & Kidneys

Acetaminophen overdose is the leading cause of calls to poison control centers in the United States, responsible for more than 56,000 emergency room visits and 2,600 hospitalizations. Acetaminophen is responsible for about 500 deaths yearly due to acute liver failure (2). Additionally, over half of all acute liver failure cases in the United States are due to acetaminophen overdoses (3). One study found that heavier use of acetaminophen was associated with an increased risk of end-stage renal disease (4). End-stage renal disease is also known as kidney disease, which occurs when there's a gradual loss of kidney function or chronic kidney disease (5). Yet the Tylenol website claims:

"TYLENOL® does not affect kidney function the way that non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin (Bayer®), naproxen sodium (Aleve®), and ibuprofen (Advil®, MOTRIN® IB) can (6)."

Depletes Levels of Glutathione

The body’s master antioxidant, known as glutathione (7), is often diminished when you take acetaminophen due to toxin build-up and damage to the liver (8). Glutathione helps protect cells from damage caused by free radicals. The buildup of free radicals has been linked to chronic diseases, such as cancer and heart disease (9). Interestingly, immediate administration of N-acetylcysteine (NAC), the precursor to glutathione, can prevent mortality from acetaminophen toxicity (10).

Cardiometabolic Risk

Several recent studies have also highlighted the influence of acetaminophen and cardiometabolic risk. Cardiometabolic risk is characterized as a person's chance of having a cardiovascular event such as a heart attack or stroke (11). One study, published in 2017, found that those taking opiates (some of which contained acetaminophen) were 95 percent more likely to be obese and 63 percent more likely to have hypertension (12).

Linked To Cancer

Researchers have also found an association between acetaminophen and cancer. A 2013 meta-analysis of epidemiological studies found that acetaminophen was associated with a significantly increased risk of kidney cancer (13). This risk is quite shocking since, according to the Tylenol website:

"The National Kidney Foundation recommends acetaminophen, the active ingredient in TYLENOL®, as the pain reliever of choice for occasional use in patients that have underlying kidney disease (14)."

Yet, according to Moffitt Cancer Center:

"Now acetaminophen is making headlines because California regulators are considering labeling it a carcinogen. It is part of the state’s Proposition 65 law requiring California to warn consumers of any products known to cause cancer, birth defects or reproductive harm (15)."

Affects Emotional Processing

Researchers at Ohio State University wanted to determine if acetaminophen affected emotional processing. They found that participants who took acetaminophen:

“...evaluated unpleasant stimuli less negatively and pleasant stimuli less positively, compared with participants who took a placebo (16)."

In other words, both negative and positive stimuli were less emotionally arousing to people who had taken acetaminophen.

May Have Neurodevelopmental Consequences During Pregnancy

Acetaminophen is currently marketed as safe during pregnancy. However, acetaminophen use may have neurodevelopmental consequences for the fetus. A 2016 study followed more than 2,000 mother-child pairs from the first trimester of pregnancy and performed several behavior tests when the children were about five years old (17). Better yet, according to WebMD:

New research shows that women who took acetaminophen, best known as Tylenol, at the end of their pregnancies were much more likely to have child with attention-deficit/hyperactivity disorder (ADHD) or autism (18)."

Linked to Stevens-Johnson Syndrome

Acetaminophen is also linked to rare but severe skin reactions such as Stevens-Johnson Syndrome and toxic epidermal necrolysis. These reactions can be fatal. Between 1969 and 2012, there were 107 such cases, of which 67 required hospitalization and 12 people died. In 2013, the FDA issued a warning and mandated that skin reactions be listed on acetaminophen-containing drug labels as a potential adverse effect (19). Exactly how acetaminophen causes these potentially fatal skin reactions is unknown, but particularly alarming is that they can occur even if you’ve taken acetaminophen in the past without any problems.

Endocrine Disruptor

Acetaminophen is an endocrine disruptor. In a 2016 study, rats that received acetaminophen had female offspring with fewer eggs, smaller ovaries, and smaller litters when they reached reproductive age. Male offspring had fewer sperm progenitor cells early in life, but these returned to normal by adulthood. Particularly concerning was the effect it had on the next generation. Granddaughters of the rats given acetaminophen were also found to have smaller ovaries and stunted reproductive functionality (20).

Linked To Asthma

Researchers have established an affiliation between acetaminophen and asthma. A 2009 systematic review and meta-analysis discovered that the probability of asthma increased with previous acetaminophen use in both adults and children (21). Moreover, prenatal exposure to acetaminophen also heightened the risk of asthma in the child, possibly due to increased oxidative stress during prepregnancy (22).
