Especially anything else that can be hard on the liver. Alcohol, most antiinflamatories, etc. Keep it liver friendly when on M1T, 'cause it's hostile enough on its own.Jarconis said:seems like anything + m1t shouldnt be taken together
Well, since Tylenol (acetaminophen) stresses the liver and can actually cause liver damage all by itself, using it at the same time as taking M1T is a bad idea, IMO. Of course, I don't know how much Tylenol you take daily, but it definitely isn't a good idea to combine the two IMO.rebo said:Ive seen on alot of other boards,that m1t and tylenol shouldnt be used together.I have back problems so i take tylenol daily(Any one know if tylenol and m1t is bad thing).Any info on this would be greatly appreciated, thanks.
if you already have a bad back, i hope you dont experience some of those back aches that some M1T users have. usually taurine/potassium helps, but if you have back problems going in, it could be real bad.rebo said:Ive seen on alot of other boards,that m1t and tylenol shouldnt be used together.I have back problems so i take tylenol daily(Any one know if tylenol and m1t is bad thing).Any info on this would be greatly appreciated, thanks.

Acetaminophen-induced hepatotoxicity.

The analgesic acetaminophen causes a potentially fatal, hepatic centrilobular necrosis when taken in overdose. The initial phases of toxicity were described in Dr. Gillette's laboratory in the 1970s. These findings indicated that acetaminophen was metabolically activated by cytochrome P450 enzymes to a reactive metabolite that depleted glutathione (GSH) and covalently bound to protein. It was shown that repletion of GSH prevented the toxicity. This finding led to the development of the currently used antidote N-acetylcysteine. The reactive metabolite was subsequently identified to be N-acetyl-p-benzoquinone imine (NAPQI). Although covalent binding has been shown to be an excellent correlate of toxicity, a number of other events have been shown to occur and are likely important in the initiation and repair of toxicity. Recent data have shown that nitrated tyrosine residues as well as acetaminophen adducts occur in the necrotic cells following toxic doses of acetaminophen. Nitrotyrosine was postulated to be mediated by peroxynitrite, a reactive nitrogen species formed by the very rapid reaction of superoxide and nitric oxide (NO). Peroxynitrite is normally detoxified by GSH, which is depleted in acetaminophen toxicity. NO synthesis (serum nitrate plus nitrite) was dramatically increased following acetaminophen. In inducible nitric oxide synthase (iNOS) knockout mice, acetaminophen did not increase NO synthesis or tyrosine nitration; however, histological evidence indicated no difference in toxicity. Acetaminophen did not cause hepatic lipid peroxidation in wild-type mice but did cause lipid peroxidation in iNOS knockout mice. These data suggest that NO may play a role in controlling lipid peroxidation and that reactive nitrogen/oxygen species may be important in toxicity. The source of the superoxide has not been identified, but our recent finding that NADPH oxidase knockout mice were equally sensitive to acetaminophen and had equal nitration of tyrosine suggests that the superoxide is not from the activation of Kupffer cells. It was postulated that NAPQI-mediated mitochondrial injury may be the source of the superoxide. In addition, the significance of cytokines and chemokines in the development of toxicity and repair processes has been demonstrated by several recent studies. IL-1beta is increased early in acetaminophen toxicity and may be important in iNOS induction. Other cytokines, such as IL-10, macrophage inhibitory protein-2 (MIP-2), and monocyte chemoattractant protein-1 (MCP-1), appear to be involved in hepatocyte repair and the regulation of proinflammatory cytokines.

Acute liver failure in the United States.
Lee WM.
Division of Digestive Liver Diseases, University of Texas Southwestern Medical Center Dallas, Texas, USA. [email protected]
In the last 5 years the use of a multicenter approach has helped to define acute liver failure (ALF) in the United States. Drug-related hepatotoxicity comprises more than 50% of cases of ALF, including acetaminophen toxicity (40%) and idiosyncratic drugs (approximately 12%). Nearly 20% of cases remain of unknown etiology. Outcome of ALF is determined by etiology; by the degree of hepatic encephalopathy present on admission; and by complications, principally infection. More than 43% survive without a transplant, 28% die, and 29% undergo liver transplantation. Liver support machines have had no impact on this condition to date. A trial of N-acetylcysteine for the treatment of ALF not related to acetaminophen toxicity is underway. Future research in ALF in the United States should focus on limiting the number of cases related to drugs, searching for causes of the indeterminate cases, and developing more effective temporary liver support.

Peace
rebo said:I have back problems so i take tylenol daily
You are correct regarding this side effect.uridium245 said:I believe there was also a study that showed tylenol or maybe it was aspirin (can't remember which) interfers with protein synthesis. Since I can't remember which it is I stay away from both. I work too hard to keep growing to let a little thing like some pain get in the way. Of course a migraine headache will invariably sway me to the dark side. :lol:
Studies point to PGF2a, specifically, as being the prostaglandin most closely tied to increase skeletal muscle protein synthesis. Skeletal muscle tissue has no capacity to actually store prostaglandins, so the only local source for PGF2a is the arachidonic acid that is retained in the outer phospholipids layer of each cell. It is the stretching of muscle fibers during intense physical exercise that causes arachidonic acid to be released and metabolized to active prostaglandins. Arachidonic acid is actually the chemical messenger first released by your muscles during intense weight training, controlling the core physiological response to exercise and regulating the intensity of all growth signals to follow. Also, anytime you have tissue injury, inflammation is involved in healing the wound. Some prostaglandins have pro-inflammatory affects. The fact is, if you work out, you have tissue injury - micro trauma to the muscle tissue. As your delayed onset muscle soreness will tell you, inflammation is involved in the healing of this micro trauma.
She originally was on pain killers for a neck and back injury from a vicious car accident, the Dr. cut her off of the meds without weening her off of them, or solving the problem of the pain...she turned to Tylenol, and then Advil too.She was not a drinker drug abuser at all.Was on the donation list for a liver, went from a 9 to a 1 in about a week and a half.I think this was over about a 9 month period.She was on the list for a while though before her condition disingrated rapidly.lancelot said:Sorry to hear about her death. But out of professional curiosity, can i ask you why she was abusing tylenol on a daily basis? how long? did she drink alcohol often? was she in chronic pain from a health condition? why didn't she go see a doctor?

Unfortunately it seems that most doctors these days treat the symptoms rather than the actual condition.lancelot said:again, sorry to hear about her death. but, the stupid azz doctor should have refered her to a PT or better yet a Chiropractor for her musculoskeletal problems incurred in the accident. pain killers don't do **** to cure her health condition.
