Zstop 500 mg Tablet

Zstop 500 mg Tablet is a prescription antiparasitic medicine that contains 500 mg of nitazoxanide in each tablet. It belongs to the anthelmintic/anti-worm category and is used to treat certain protozoal and worm-related intestinal infections. Zstop 500 mg Tablet is taken by mouth and is usually chosen when a doctor wants the adult tablet strength for a specific infection and treatment plan. It does not work for every type of infection, so the exact use depends on the diagnosis.

How it works: Nitazoxanide works by interfering with the energy-making process of susceptible parasites, which helps stop them from surviving and multiplying. In tablet form, Zstop 500 mg Tablet delivers a measured oral dose that is absorbed in the body and then acts against the infection.

Zstop 500 mg Tablet is the higher tablet strength compared with Zstop 200 mg Tablet, so it is generally more suitable for older children who can swallow tablets and for adults when this exact dose is prescribed. Because each tablet already contains 500 mg of nitazoxanide, it may reduce the number of tablets needed per dose compared with lower-strength tablets. A doctor may choose Zstop 500 mg Tablet when the standard adult regimen or a weight-based regimen calls for this strength.

• Swallow Zstop 500 mg Tablet whole with water; do not crush or chew it unless your doctor says otherwise.
• Take it with food, since nitazoxanide is usually better tolerated and absorbed when taken with a meal.

Each Zstop 500 mg Tablet provides 500 mg of nitazoxanide per tablet. How often it is taken depends on the infection being treated and the patient’s age and weight; in many adult regimens, it is taken twice daily, but the doctor decides the exact schedule. Do not exceed the prescribed daily amount, and do not assume Zstop 500 mg Tablet should be used the same way as the 200 mg strength.

Do not change your dose or stop the medicine without speaking to your doctor.
