A small amount of denatonium benzoate can be added to give it a bitter taste, repelling animals and making it unpleasant for people.<\/p>\n<p>In the event of ingestion, it is crucial to go to an emergency medical center for treatment against ethylene glycol poisoning.<\/p>\n<h2><span id=\"Effects-of-poisoning-and-intoxication-with-ethylene-glycol\">Effects of poisoning and intoxication with ethylene glycol<\/span><\/h2>\n<ul>\n<li>Kidney damage.<\/li>\n<\/ul>\n<p>When ingested, it is converted into calcium oxalate in the kidneys. To minimize harm to the body, ethanol can be administered while seeking medical help. Alcoholic beverages slow the conversion of methanol to formaldehyde and <a href=\"https:\/\/www.mismumi.com\/en\/formic-acid\/\">formic acid<\/a>. These substances are responsible for making ethylene glycol toxic.<\/p>\n<p>Although <strong>detoxification or treatment is not recommended for unqualified individuals<\/strong>, in medical practice, specialists can administer ethanol intravenously to slow down and alleviate the potential damage from ethylene glycol and methanol poisoning. Fomepizole is also used today as an antidote and treatment for ethylene glycol poisoning.
