I have a friend who last year suffered severe drug addiction and decided to consume windshield washer fluid that contains methanol/isopropanol. He drank it from Saturday to Wednseday before being caught in college and taken to A&E.
Luckily for him, he didn't die or suffer from retinal damage/organ damage/kidney damage. The doctors were baffled. He had 2900mg/L of methanol in his blood and was treated with fomepizole.
The nephrologist said that he was lucky that the mixture contained isopropanol (propan-2-ol) because that most likely inhibitied alcohol dehydrogenase in his liver from converting methanol to formaldehyde and then formic acid.
Methanol in it's unconverted form is not harmful to the body.
Is this true or not?
