Parasitic worm infections are treated with antiparasitic medications chosen by species and severity. Common drugs include albendazole and mebendazole for roundworms and hookworms, praziquantel for tapeworms and flukes, ivermectin for strongyloidiasis and filariasis, and niclosamide for certain cestodes. In some settings, nitazoxanide is used for select intestinal parasites, and procurement discussions may reference nizonide wholesale availability. Treatment may involve single or repeated doses, supportive care, and nutritional correction. Public health measures, sanitation, and follow-up testing help prevent reinfection and complications. Clinical evaluation and individualized regimens are essential, especially for children, pregnancy, coinfections, and regions with resistance patterns and monitoring outcomes.
