Niclosamide 500 mg is an antiparasitic medication primarily used to treat tapeworm infections in the intestines. It works by disrupting the tapeworm’s ability to absorb glucose, which ultimately kills the parasite. This medication is effective against several types of tapeworms, including Taenia saginata (beef tapeworm) and Taenia solium (pork tapeworm). After taking Niclosamide, the dead worms are passed out of the body through the stool. It’s important to follow the doctor’s instructions closely for the best results, and proper hygiene is essential to prevent reinfection.
