The Dangers of Methanol-Based Antifreeze and How It Affects Health
Methanol-based antifreeze can seriously impact human health, leading to a range of dangerous conditions. This warning comes from Valentina Pigareva, a therapist at the MEDSI Clinic in Krasnogorsk and deputy chief physician for quality control and safety of medical activities. Her comments were shared with a correspondent for a news outlet focused on public health concerns.
These liquids are often sold illegally beside roads from cars, though they can still be found in regular retail outlets. The risk comes from methyl alcohol, a potent poison that disrupts the nervous system, the vascular system, and can damage the optic nerves and retina. When inhaled, when there is skin contact with intact skin, or if ingested, it can trigger acute poisoning with potentially fatal outcomes, according to the physician.
Long-term exposure to methanol may cause dizziness, chest and liver discomfort, and a range of neurological and systemic issues. It can contribute to neurasthenia, autonomic dysfunction, blurred vision, and problems affecting the gastrointestinal tract and upper airways, as well as dermatitis. People who encounter methanol repeatedly or over extended periods are at increased risk of these health effects.
There have been incidents where methanol entered the body by accident. Even small amounts, as little as 5 to 10 grams, can cause severe poisoning with the possibility of blindness. Higher doses, around 30 grams, may be fatal. In the event of antifreeze exposure, the recommended immediate action is to call emergency services and, if advised by professionals, to avoid inducing vomiting unless specifically instructed to do so by medical personnel. Prompt medical evaluation is crucial to manage poisoning effectively and prevent lasting damage.
The public is urged to exercise caution and avoid purchasing or handling methanol-containing antifreeze from unverified sellers. Awareness of the signs of poisoning and a quick response can save lives and reduce the risk of irreversible harm. In regions with harsher climates, the temptation to rely on cheap, readily available antifreeze products can be strong, but safety must come first. If exposure is suspected, seeking immediate medical attention is essential, even if symptoms are not yet severe. This information is supported by clinical experts and public health authorities who emphasize prevention, early detection, and rapid treatment as the best safeguards against methanol poisoning.

In summary, methanol-containing antifreeze poses real dangers to health. It can cause acute poisoning, nerve and eye damage, and severe systemic effects with the potential for long-term harm. Avoiding illicit purchases and ensuring proper handling and storage are critical steps. When in doubt, consult medical professionals and rely on approved, properly labeled products from reputable suppliers. Public health guidance remains clear: stay informed, stay safe, and act quickly if exposure occurs. [Attribution: MEDSI Clinic clinical staff]
