What is Niclosamide 500 mg?

Niclosamide 500 mg is an anti-parasitic medication primarily used to treat infections caused by tapeworms in the intestines. It works locally within the digestive system and is not significantly absorbed into the bloodstream, which helps reduce systemic side effects.

This medication is commonly prescribed for infections such as:

• Taenia saginata (beef tapeworm)
• Taenia solium (pork tapeworm)
• Diphyllobothrium latum (fish tapeworm)

The Niclosamide 500 mg tablet is usually taken orally and is considered safe when used under proper medical guidance.

How Does Niclosamide Work?

Niclosamide works by targeting the metabolism of parasites. It inhibits the parasite’s ability to produce energy by blocking oxidative phosphorylation in their cells.

In simple terms:

• It deprives the parasite of energy
• The parasite becomes immobilized
• Eventually, it dies and is eliminated through the stool

Unlike many other medications, Niclosamide 500 mg does not kill the eggs of parasites directly, which is why proper hygiene and sometimes repeat doses are necessary.
