Drug Interactions (FDA Label)

INTERACTIONS Competition for binding sites may occur when administered concurrently with other highly plasma protein-bound drugs with narrow therapeutic indices. Monitor for adverse reactions ( 7 ).

7.1 Highly Protein Bound Drugs with Narrow Therapeutic Indices Tizoxanide (the active metabolite of nitazoxanide) is highly bound to plasma protein (>99.9%). Therefore, monitor for adverse reactions when administering nitazoxanide concurrently with other highly plasma protein-bound drugs with narrow therapeutic indices, as competition for binding sites may occur (e.g., warfarin).

Contraindications

Hypersensitivity (4.1)

4.1 Hypersensitivity Nitazoxanide tablets and ALINIA for Oral Suspension are contraindicated in patients with a prior hypersensitivity to nitazoxanide or any other ingredient in the formulations.
