What is Albendazole

Albendazole is a salt recommended as an effective treatment against worm infections. 

Medicines containing Albendazole are prescription based and work by killing the worms that cause infections. 

It belongs to the Anthelmintic drug class. By preventing worms from absorbing sugar, it causes them to lose energy and eventually die.

Working of the salt
