What Is Niclosamide 500 mg?

Niclosamide 500 mg is an oral prescription medicine containing 500 mg of niclosamide, an anthelmintic (antiparasitic) medication.

It is used to treat specific tapeworm infections in the intestine. Niclosamide acts within the intestinal tract to eliminate susceptible parasites and is prescribed only when medically appropriate.

How Does Niclosamide Work?

Niclosamide works by interfering with the parasite’s energy production, causing it to lose viability. The affected parasite is then eliminated from the body through normal bowel movements.

The medicine acts mainly within the intestines and is minimally absorbed into the bloodstream when taken as directed.
