Documented Uses

• Animal Drugs -> FDA Approved Animal Drug Products (Green Book) -> Active Ingredients
• For the treatment of diarrhea in adults and children caused by the protozoa Giardia lamblia, and for the treatment of diarrhea in children caused by the protozoan, Cryptosporidium parvum. Nitazoxanide has not been shown to be superior to placebo medication for the management of diarrhea caused by Cryptosporidium parvum in patients with HIV/immunodeficiency.
• Nitazoxanide is an antimicrobial with activity against several parasitic worms and protozoa that is used predominantly in the United States in treatment of giardiasis and cryptosporidiosis. Nitazoxanide therapy has not been reported to cause serum aminotransferase elevations during therapy or clinically apparent liver injury.
• Breast Feeding; Lactation; Milk, Human; Anti-Infective Agents; Antiparasitic Agents
• Take with food. Food improves oral bioavailability.
• Drugs used to treat or prevent parasitic infections.
