Niclosamide (trade name Niclocide) is a teniacide in the anthelmintic family especially effective against cestodes that infect humans. It is also used as a piscicide. While antihelmintics are a drug family used to treat worm infections, niclosamide is used specifically to treat tapeworms and is not effective against other worms such as pinworms or roundworms. It is a chewable tablet taken orally, dosage depending on type of worm and patient's age and/or weight. Niclosamide molecules are lethal to tapeworms upon contact.

It is on the World Health Organization's List of Essential Medicines, a list of the most important medications needed in a basic health system.[1]

Side effects[edit]

The medication can have side effects such as abdominal pain, anorexia, diarrhea, and emesis. 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.

Mechanism of action[edit]

Niclosamide uncouples oxidative phosphorylation in the tapeworm.[2]
