What is Niclosamide 500 mg?
Niclosamide 500 mg is an anthelmintic (anti-parasitic) drug that effectively kills tapeworms and other intestinal parasites. It is available in chewable tablet form, making it easier to administer, especially for children.
Originally developed in the 1950s, Niclosamide remains a first-line treatment for tapeworm infections due to its high efficacy and safety profile. Recent research has also explored its potential in treating viral infections (like COVID-19) and certain cancers, though these uses are still under investigation.

What is Niclosamide 500 Used For? 🦠
Niclosamide 500 is used primarily to treat:
Tapeworm infections (such as beef tapeworm, pork tapeworm, fish tapeworm, dwarf tapeworm).
Not effective against pinworms or roundworms.
Other off-label research is investigating uses in cancer, viral infections, and metabolic diseases; however, these are not yet approved indications.
🔬 How Does Niclosamide 500 Work?
Niclosamide works by:
Inhibiting energy production in the parasite’s cells.
Disrupting oxidative phosphorylation and anaerobic metabolism.
This causes the tapeworm to become immobile, disintegrate, and detach from the intestinal wall.
The dead parasites are then naturally expelled through the digestive system.

Some notable benefits:
Highly effective against adult tapeworms
Minimal systemic absorption – mostly works locally in the gut
