What is Niclosamide 500 mg?

Niclosamide 500 mg is an antiparasitic medication primarily used to treat infections caused by tapeworms. It works locally in the intestines and is not significantly absorbed into the bloodstream, making it a safe option for many patients.

The Niclosamide 500 mg tablet is specifically formulated to eliminate parasites by disrupting their metabolism, leading to their death and eventual removal from the body through natural processes.

How Does Niclosamide Work?

Niclosamide works by interfering with the energy production of parasites. It inhibits oxidative phosphorylation in the mitochondria of the worm, effectively starving it of energy. Without energy, the parasite cannot survive, attach to the intestinal walls, or reproduce.

This targeted action ensures that the drug affects the parasite without significantly impacting human cells. Because it acts locally in the intestines, systemic side effects are minimal compared to many other medications.
