Deworming medicine is a type of medication used to eliminate intestinal parasites, such as worms, from humans and animals. The most widely used deworming medication is called albendazole or mebendazole, which is a secure method of treating intestinal worms that are used all over the world. The World Health Organization (WHO) recommends deworming as a public health intervention for all young children 12-23 months of age, preschool children 1-4 years of age, and women of reproductive age with single-dose albendazole or mebendazole after their first trimester of pregnancy and where the prevalence of worm infections is 20% or higher. The Centers for Disease Control and Prevention recommends deworming treatments at 2, 4, 6, and 8 weeks of age for puppies, as well as concurrent treatments given to the mother to eliminate reactivated larvae and prevent horizontal transmission from puppies that may be shedding roundworm and hookworm eggs. They also recommend deworming treatments at 3, 5, 7, and 9 weeks of age for kittens and the mother. Deworming is an important public health measure that can dramatically reduce the burden of worms caused by soil-transmitted helminth infections.
