Niclosamide belongs to the family of medicines called anthelmintics. Anthelmintics are medicines used in the treatment of worm infections.
Niclosamide is used to treat broad or fish tapeworm, dwarf tapeworm, and beef tapeworm infections. Niclosamide may also be used for other tapeworm infections as determined by your doctor. It will not work for other types of worm infections (for example, pinworms or roundworms).
Niclosamide works by killing tapeworms on contact. The killed worms are then passed in the stool. However, you may not notice them since they are sometimes destroyed in the intestine.
Niclosamide is available only with your doctor's prescription.
