My neonatology class was like 18 years ago and so I think @kiddiedoc would be who I would defer to. I specialized in adult nursing.This is what I found. SIAP. The concern wrt Tylenol stems from it depletion of glutathione needed for mitochondrial and cellular function and development. The depletion of glutathione suggests it could be playing a role in the increased cases of autism. @kiddiedoc @NurseGoodVol..what is your take on this info?
Tylenol (
acetaminophen) can deplete glutathione in the body, particularly mitochondrialand intracellular stores, and also inhibit glutathione reductase, an enzyme essential for glutathione recycling. This depletion and inhibition contribute to oxidative stress and can be part of the mechanism behind acetaminophen-induced toxicity, especially during overdose.
Mechanism of Glutathione Depletion
Consequences of Glutathione Depletion
- Reactive Metabolite Formation: Acetaminophen is metabolized in the liver to a reactive metabolite called NAPQI.
- Glutathione Conjugation: Glutathione is a key antioxidant that neutralizes toxic substances by forming conjugates. The reactive NAPQI metabolite can bind with glutathione, using it up.
- Depletion of Stores: With a high dose of acetaminophen or an overdose, the amount of NAPQI produced can overwhelm the body's glutathione stores, leading to significant depletion.
- Inhibition of Glutathione Reductase: Research suggests that acetaminophen can inhibit glutathione reductase, an enzyme that regenerates glutathione from its oxidized form. This further impairs the body's ability to maintain adequate glutathione levels.
^^^This last sentence is interesting, but sounds like there would have to be over use of Tylenol well beyond the prescribed amount to have such an impact, but that’s me just spitballing.
- Increased Oxidative Stress: With reduced glutathione, the body's ability to fight oxidative stress decreases, which can lead to cellular damage.
- Hepatotoxicity (Liver Toxicity): In the liver, glutathione plays a crucial role in detoxification. Depletion can lead to liver cell damage.
- Impact on Other Organs: Glutathione depletion has also been observed in other tissues, including the lungs and brain, suggesting a broader systemic impact.
I can tell you the CDC recommendations for daily Tylenol use changed about 5 years ago from 4G a day to 3G a day.
I have had a hundred Tylenol OD’s in 19 years and we run Acetadote(acetylcysteine) drips that replenish glutathiones to reduce liver damage.
Overuse of any drug is bad because they all come with side effects. Only when needed and for the shortest time possible is good advice.
Public service announcement!!!
Oh and there is a recall on coreg and metoprolol. 2 very common meds for hypertension so please check for the recall on those drugs if you are currently taking them and contact your pharmacy if you have the recall lot numbers.
