Niclosamide, marketed under brand names like Niclocide, is an effective treatment for tapeworm infections such as diphyllobothriasis, hymenolepiasis, and taeniasis. It is taken orally and does not affect other types of worms, such as pinworms and roundworms.
Niclosamide Uses
Niclosamide is an anthelmintic, which means it kills parasitic worms. Anthelmintics are medications that are used to treat worm infections.
It is used to treat tapeworm infections such as large or fish tapeworm, dwarf tapeworm, and beef tapeworm.
Niclosamide can also be used to treat other tapeworm infections if your doctor recommends it. It is ineffective against other forms of worm infections (for example, pinworms or roundworms).
Niclosamide kills tapeworms when they come into contact with it. The destroyed worms are passed in the stool, although they may not always be visible in the stool.
Niclosamide requires a doctor’s prescription.
How to Use Niclosamide
Niclosamide can be taken without food (either 1 hour before or 2 hours after a meal). However, taking it after a light meal can help avoid stomach discomfort (e.g: breakfast).
Chew or crush Niclosamide tablets thoroughly before swallowing them whole with a small amount of water. For children, crush tablets into a fine powder and mix with a small amount of water to form a paste.
Follow your doctor’s instructions carefully for the complete clearance of your infection. Typically, one dose is sufficient, but some patients may need a second dose to fully clear the infection.
