Nitazoxanide is an antiparasitic and antiviral medication used to treat various infections caused by parasites and certain viruses. It works by disrupting the energy production in these microorganisms, effectively stopping their growth and replication. This makes it useful for treating conditions like giardiasis and cryptosporidiosis, which are caused by parasites found in contaminated water. In addition to its antiparasitic properties, Nitazoxanide has shown potential against some viral infections, including influenza and norovirus. It is available in tablet and liquid form, making it easy to administer. As with any medication, it is important to follow a healthcare provider's guidance when using Nitazoxanide.
