Nizonide 500 mg Tablet

Nizonide 500 mg Tablet contains 500 mg of nitazoxanide in each tablet. It belongs to the anthelmintic/anti-worm medicine class and is used to treat certain parasitic intestinal infections, including infections caused by protozoa and some worms. This tablet is taken by mouth and is prescribed when a clinician decides nitazoxanide is appropriate for the specific infection.

How it works: Nitazoxanide works by interfering with the parasite’s ability to make energy, which helps stop it from growing and surviving in the gut. As a tablet, Nizonide 500 mg Tablet delivers the medicine in a swallowed oral form that reaches the intestines after absorption.

Nizonide 500 mg Tablet is a higher-strength tablet, so it is generally used when a doctor wants a full adult tablet dose rather than a lower-strength option. Because this is the 500 mg tablet, it is not meant for self-selecting or splitting a diagnosis; the dose schedule depends on the infection being treated and the patient’s age and health. A doctor may choose Nizonide 500 mg Tablet for convenient twice-daily dosing in adults or older children who can swallow tablets.

Each Nizonide 500 mg Tablet provides 500 mg of nitazoxanide per tablet. The exact dosing schedule depends on the infection being treated, but this strength is commonly used on a twice-daily schedule when prescribed; your doctor decides the right dose, duration, and whether this tablet strength is appropriate.
