Niclosamide
Niclosamide, sold under the brand name Niclocide among others, is an anthelmintic medication used to treat tapeworm infestations, including diphyllobothriasis, hymenolepiasis, and taeniasis. It is not effective against other worms such as flukes or roundworms. It is taken by mouth. Side effects include nausea, vomiting, abdominal pain, and itchiness. It may be used during pregnancy. It works by blocking glucose uptake and oxidative phosphorylation by the worm. Niclosamide was first synthesized in 1958. It is on the World Health Organization's List of Essential Medicines. Niclosamide is not available for human use in the United States. Side effects Side effects include nausea, vomiting, abdominal pain, constipation, and itchiness. Rarely, dizziness, skin rash, drowsiness, perianal itching, or an unpleasant taste occur. For some of these reasons, praziquantel is a preferable and equally effective treatment for tapeworm infestation. Important Note: Niclosamide kills the pork tapeworm and results in its digestion. This then may cause a multitude of viable eggs to be released and may result in cysticercosis. Therefore, a purge should be given 1 or two hours after treatment. CNS cysticercosis is a life-threatening condition and may require brain surgery. Mechanism of action Niclosamide inhibits glucose uptake, oxidative phosphorylation, and anaerobic metabolism in
