Nitazoxanide 500 mg

Nitazoxanide 500 mg is an antiparasitic and antiprotozoal medicine used for the treatment of certain intestinal infections. It is commonly prescribed for diarrhea caused by Giardia lamblia (giardiasis) or Cryptosporidium parvum (cryptosporidiosis) in appropriate patients.

Nitazoxanide works by interfering with energy metabolism that is essential for susceptible parasites and protozoa, helping to eliminate the infection.

Product Information

Uses of Nitazoxanide 500 mg

Nitazoxanide may be prescribed for:

• Giardiasis caused by Giardia lamblia

• Cryptosporidiosis caused by Cryptosporidium parvum

• Diarrhea associated with certain susceptible protozoal infections

The appropriate treatment depends on the causative organism, age, medical condition, and healthcare professional’s assessment.

How Nitazoxanide 500 mg Works

Nitazoxanide is converted to an active metabolite called tizoxanide.

Tizoxanide interferes with an enzyme-dependent metabolic pathway involved in energy production in susceptible anaerobic organisms and parasites. This disrupts the parasite’s ability to survive and reproduce, helping clear the infection.

• Helps treat certain protozoal intestinal infections

• Effective against susceptible Giardia infections

• Used for certain Cryptosporidium infections

• Helps reduce diarrhea associated with susceptible infections

• Available as a convenient oral tablet for appropriate patients
