Niclobest 500 Mg (Niclosamide)

Niclobest 500 mg is a prescription anthelmintic medication containing 500 mg of niclosamide, manufactured by Kachhela Medex Pvt. Ltd. It is used to treat tapeworm infections, including beef tapeworm (Taenia saginata), pork tapeworm (Taenia solium), fish tapeworm (Diphyllobothrium latum), and dwarf tapeworm (Hymenolepis nana). Niclosamide works by inhibiting mitochondrial oxidative phosphorylation and glucose uptake in tapeworms, killing adult worms on contact, which are then expelled in the stool or destroyed in the intestine. Administered as chewable tablets, it is taken after a light meal to minimize stomach upset, with a single dose often sufficient for most infections, though dwarf tapeworm may require a 7-day course. Niclobest 500 mg is minimally absorbed from the gastrointestinal tract, reducing systemic side effects, but requires medical supervision, especially for pregnant women or those with allergies, as it is not effective against other worms like pinworms or roundworms.
