Methanol poisoning occurs when a person ingests or is exposed to methanol, a type of alcohol found in antifreeze, solvents, and fuel. Unlike ethanol, the alcohol found in beverages, methanol is toxic and can lead to serious health issues. Symptoms may include headache, dizziness, nausea, vomiting, and in severe cases, blindness or death. The body metabolizes methanol into formaldehyde and formic acid, which are harmful substances. Treatment typically involves administering ethanol or fomepizole, which can help prevent the formation of toxic metabolites. Early medical intervention is crucial for a better outcome in cases of methanol poisoning.
