Methanol Overdose: Symptoms, Causes and Treatments

Methanol is a toxic alcohol found in solvents, antifreeze, and fuels. It is used widely in industrial applications. Although Methanol is a common solvent, it is also a hazardous substance. Inhalation or ingestion of large amounts can lead to methanol overdose and its attendant symptoms.

Methanol overdose typically presents with a wide variety of symptoms. These symptoms can include but are not limited to:

  • Headache, dizziness, and confusion
  • Nausea and vomiting
  • Slurred speech and difficulty speaking
  • Abdominal pain and diarrhea
  • Blurred or double vision
  • Anxiety and restlessness
  • Irregular heartbeat
  • Urine output that is much lower than normal

In extreme cases, Methanol overdose can cause permanent blindness or coma and may even be fatal. If you suspect someone you know has been exposed to Methanol, seek medical attention immediately.

Causes of Methanol Overdose

Methanol poisoning occurs when a person comes into contact with large amounts of Methanol whether via ingestion, inhalation or through contact with skin or eyes. Common sources of Methanol exposure are industrial solvents, gasoline, antifreeze, nail polish remover and some types of paint thinner.

Ingestion of large amounts of Methanol is the most common cause of an overdose. When swallowed, Methanol is quickly absorbed into the bloodstream and can affect an individual quickly. Inhalation of Methanol or contact with the skin or eyes can also be hazardous and cause serious injury.

Treatment for Methanol Overdose

Treatment for Methanol overdose depends on the severity of the exposure. In mild cases, supportive care may be sufficient. This includes monitoring the patient’s vital signs and providing fluids as needed. For more severe cases, dialysis may be necessary.

In very severe cases, antidotes such as fomepizole or ethanol may be administered to counteract the effects of methanol poisoning. These antidotes prevent the body from breaking down the Methanol into its toxic byproducts. Additionally, medications to help manage the symptoms such as antiemetics and benzodiazepines may be prescribed.

Prevention of Methanol Poisoning

The best way to prevent Methanol poisoning is by avoiding exposure and taking proper safety precautions when working with chemicals. Make sure to read and follow all safety labels and guidelines. Wear protective clothing, such as gloves, an apron, and a face shield when handling solvents or working with fuels.

Also, store potentially hazardous chemicals away from food and out of the reach of children and pets. In the event of a spill, clean it up immediately and avoid inhalation or contact with the skin or eyes.
