Albendazole is a broad-spectrum anthelmintic widely used to treat intestinal worm infections in humans, including roundworms, hookworms, and whipworms. Its effectiveness relies on proper dosing, timing, and adherence to medical guidelines. For adults and children over two years, a single 400 mg dose is commonly recommended for most infections, while specific cases may require repeated doses or longer treatment.albendazole 400 mg works by inhibiting the worms’ ability to absorb glucose, leading to energy depletion and death of the parasites.For optimal results, albendazole should be taken with a fatty meal, as this increases absorption and enhances efficacy. Before treatment, individuals should confirm infection type through medical evaluation, since different worms may require tailored dosing. Pregnant women, particularly in the first trimester, should avoid albendazole unless prescribed by a physician due to potential risks. Side effects are generally mild, including nausea, abdominal pain, or headache, but serious reactions are rare.Preventive measures, such as proper handwashing, cooking food thoroughly, and avoiding contaminated soil or water, complement albendazole therapy. Overall, effective use of albendazole, combined with hygiene practices and medical guidance, can significantly reduce the prevalence and complications of intestinal worm infections in humans.
