Alcohol dehydrogenase instead enzymatically converts ethanol to acetaldehyde, a less toxic organic molecule. [ 15 ] [ 20 ] Additional treatment may include sodium bicarbonate for metabolic acidosis, and hemodialysis or hemodiafiltration to remove methanol and formate from the blood. [ 15 ]
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
Toxicity from methanol is related to the dose you get and how your body handles it. As with alcohol, the less you weigh, the more you can be affected by a given amount.
Outbreaks of methanol toxicity have occurred when methanol is used to lace moonshine (bootleg liquor), [1] which is an alcohol-related crime. However, it may also happen if ethanol has been contaminated. Methanol is a toxic alcohol to humans via ingestion due to metabolism.
Fomepizole is used to treat ethylene glycol and methanol poisoning. It acts to inhibit the breakdown of these toxins into their active toxic metabolites. Fomepizole is a competitive inhibitor of the enzyme alcohol dehydrogenase, [6] found in the liver. This enzyme plays a key role in the metabolism of ethylene glycol, and of methanol.
Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression or aspiration of vomit if vomiting occurs while the person is unresponsive. Emergency treatment strives to stabilize and maintain an open airway and sufficient breathing while waiting for the alcohol to metabolize.

1 US gallon or 3.785 litres of denatured alcohol in a metal container. Denatured alcohol, also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom, and as denatured rectified spirit, is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.
