GOOGLE OVERVIEW

Thiabendazole is a broad-spectrum antihelminthic and antifungal agent with several applications. It is used to treat parasitic worm infections in humans and animals, and as a fungicide to prevent fungal growth on fruits and vegetables, as well as in various other applications like seed treatment and post-harvest treatment. 
 
Key Uses:
Antifungal:
It acts as a fungicide to prevent fungal growth on fruits and vegetables after harvest, and is also used as a seed treatment. Thiabendazole can be found as a component in various formulations like dusts, flowable concentrates, and emulsifiable concentrates. 
 
Other Applications:
Thiabendazole is also used in veterinary medicine, as a preservative in paints, carpets, adhesives, and textiles, and even as a heavy metal chelating detoxification agent. 
 
Important Considerations:
 
Side Effects:
Thiabendazole can cause minor side effects such as dizziness, nausea, and gastrointestinal upset. More severe adverse events, including liver disease and hypersensitivity reactions, are also possible. 
 
Availability:
While thiabendazole has been largely replaced by other antihelmintic medications in some areas, it is still available in many countries, particularly for veterinary use. 
 
Mechanism of Action:
Thiabendazole works by inhibiting a key enzyme (fumarate reductase) in the mitochondria of helminths, disrupting their energy production and ultimately leading to their death. 
 
Historical Context:
 
Thiabendazole was first registered as a pesticide in the US in 1969. 
 
It was initially widely used for treating parasitic infections in humans and animals, and as a fungicide. 
 
Due to the availability of newer, better-tolerated medications, thiabendazole has seen a decline in its use in some areas.
