Is cypermethrin a neurotoxin?
Cypermethrin is a class II synthetic pyrethroid pesticide and crosses the blood brain barrier and exerts neurotoxicity in the central nervous system and also induces motor deficits.
Is alpha cypermethrin safe for humans?
In particular, three pyrethroid compounds, namely deltamethrin, permethrin, and alpha-cypermethrin, are commonly used as insecticides and are recommended for in-home insect control because they are considered to be relatively non-toxic to humans in all stages of life.
What is antidote of cypermethrin?

What’s the difference between permethrin and cypermethrin?

What happens to cypermethrin in the environment? days, although it can range from two to eight weeks (6, 9). Soil microbes rapidly break down cypermethrin (6). See box on half-life.
Is pyrethrin a neurotoxin?
Pyrethrins and pyrethroids are neurotoxic as a result of their ability to alter sodium channels and cause repetitive nervous discharges or membrane depolarization. Clinical signs associated with acute intoxication are related to nervous system stimulation.
Is pyrethrin a carcinogen?
In 1999, the US EPA classified pyrethrins as likely carcinogens via the route of ingestion. This classification was supported by studies in rats and mice who developed thyroid tumors following high-dose ingestion over two years.
Is pesticide spray harmful to humans?
The exposure to pesticides may result in irritation to eye, nose, and throat; damage to central nervous system and kidney; and increased risk of cancer. Symptoms due to pesticides exposure may include headache, dizziness, muscular weakness, and nausea.
