Niclosamide: An Overview of Its Medical Uses

Niclosamide is an antiparasitic medication that has been used for many years to treat certain intestinal worm infections, especially tapeworms. It works by interfering with the parasite’s energy production, which causes the worm to lose its ability to survive in the body. Because of this targeted action, niclosamide mainly affects the parasite without significantly impacting human cells.Doctors commonly prescribe niclosamide for infections caused by beef tapeworm, pork tapeworm, and fish tapeworm. The medicine is taken orally and usually works within a short period when used as directed. In many cases, it is combined with proper hygiene and follow-up testing to ensure the infection is fully cleared.Niclosamide is generally well tolerated, though some people may experience mild side effects such as nausea, stomach discomfort, or headache. It should always be taken under medical supervision, especially for children or individuals with other health conditions. When used correctly, niclosamide remains an effective and reliable treatment option for specific parasitic infections.
