Use in special groups

    Use in pregnancy: Pregnancy Category B: However, there are no adequate and well-controlled studies in pregnant women. So this drug should be used during pregnancy only if clearly needed.

    Use in lactation: It is not known whether nitazoxanide is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when nitazoxanide is administered to a nursing woman.
