Important Safety Information
- ALINIA Tablets and ALINIA for Oral Suspension are contraindicated in patients with a prior hypersensitivity to nitazoxanide or any other ingredient in the formulations.
- The most common adverse reactions in ≥2% of patients were abdominal pain, headache, chromaturia and nausea.
- 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).
- ALINIA tablets and ALINIA for Oral Suspension should be taken with food.
- Safety and efficacy of ALINIA for Oral Suspension in pediatric patients less than one year of age has not been studied.
