Nitazoxanide 500 mg is a broad-spectrum antiparasitic and antiviral medication used to treat a variety of infections caused by parasites. Its most common use is in the treatment of intestinal infections caused by protozoa, which are microscopic, single-celled organisms.

Parasites Treated by Nitazoxanide

Giardia lamblia (Giardiasis)
Nitazoxanide effectively treats giardiasis, an intestinal infection caused by the Giardia parasite. Symptoms include diarrhea, abdominal cramps, bloating, and nausea. The medication helps eliminate the parasite from the digestive system, restoring normal gut function.

Cryptosporidium parvum (Cryptosporidiosis)
Cryptosporidiosis is another common infection treated by nitazoxanide. It is caused by the Cryptosporidium parasite, often resulting in severe, watery diarrhea. This infection is particularly dangerous for individuals with weakened immune systems, and nitazoxanide is one of the most effective treatments available.

Other Parasites
Nitazoxanide has also shown efficacy against certain helminths (worms) and other protozoan infections, although these uses may vary based on regional approvals. It may be prescribed for roundworms or other intestinal parasites in some cases.

How It Works

Nitazoxanide disrupts the energy production processes in parasites, making it difficult for them to survive and multiply. This leads to their eventual elimination from the body.

Always take nitazoxanide as prescribed by your healthcare provider. Completing the full course ensures the parasite is fully eradicated and reduces the risk of recurrence. If symptoms persist, consult your doctor for further evaluation.
