Parathion-methyl, a white powder, is an organophosphorous insecticide. Because it has been designated as a specified poisonous substance, handle it in accordance with the Poisonous and Deleterious Substances Control Law. Its properties are similar to those of parathion, only it decomposes more easily than parathion.

Parathion-methyl, also known as methyl parathion, falls into the category of a historical insecticide with some lingering medical connections. Here's a breakdown of its key points:
Past Use as an Insecticide:
- Parathion-methyl was an organophosphate insecticide similar to parathion (described previously). It was used to control insects in agriculture on various crops [1].
Medical Use (Limited and Discontinued):
- In rare cases, parathion-methyl was prescribed medically to treat scabies, a parasitic skin infestation. However, this use was uncommon and has largely been discontinued [2].
Current Status:
- Due to safety concerns and the availability of safer alternatives, parathion-methyl is no longer widely used as an insecticide or medication [1, 2].
- Many countries have restricted or banned its use entirely.
Safety Issues:
- Parathion-methyl is toxic and can cause serious health problems if ingested, inhaled, or absorbed through the skin. Symptoms can range from nausea and vomiting to respiratory failure and death [1].
- Similar to parathion, it disrupts the nervous system by inhibiting an enzyme called acetylcholinesterase, leading to a buildup of acetylcholine, a neurotransmitter [1].
Important Considerations:
- Safer alternatives: Safer and more effective insecticides and medications are available for pest control and scabies treatment, respectively.
- Regulations: The use of parathion-methyl is likely strictly regulated or banned in your area.
