Methanol Poisoning

Why in the news?                       

           Recently, six tourists tragically lost their lives in Laos due to suspected methanol poisoning which has raised global alarm.

About Methanol Poisoning:

• It is a serious and potentially life-threatening condition that arises when methanol, a type of alcohol widely used in industrial applications, is ingested, inhaled, or absorbed through the skin.
• Methanol’s toxic effects emerge after the body metabolises it into harmful compounds like formaldehyde and formic acid.
• These byproducts can wreak havoc on the nervous system, optic nerves and other vital organs.

How does alcohol cause methanol poisoning?

• It typically occurs when counterfeit or illicit alcohol, often containing methanol, is consumed instead of ethanol, the type of alcohol found in beverages.
• In the body, methanol is metabolised by the liver enzyme alcohol dehydrogenase into formaldehyde and then into formic acid, both of which are toxic.
• Methanol poisoning can indeed be fatal if left untreated. The toxic byproducts lead to complications.
• Metabolic Acidosis: A dangerous drop in blood pH levels.
• Optic Nerve Damage: Potentially resulting in partial or complete blindness.
• Central Nervous System Depression: Causing confusion, coma or death.

Prevention of the methanol poisoning:

• Avoid Non-Drinkable Alcohol: Never consume industrial alcohol or alcoholic beverages from unverified sources, as they may contain methanol.
• Regulated Alcohol Sales: Governments should ensure the production and sale of alcohol adhere to safety standards to eliminate harmful levels of methanol.
• Public Awareness: Educate communities about the dangers of consuming illicit or counterfeit alcohol.
• Methanol Screening: Regular testing of alcoholic products in unregulated markets can help identify and prevent contaminated beverages from reaching consumers.
• Seek Prompt Medical Care: If methanol poisoning is suspected, immediate medical attention can be life-saving.
