Precautions

Caution is recommended in patients with renal and/or hepatic disease.

Nitazoxanide should be taken with food.

Patients with diabetes should be aware that the suspension contains 1.48 grams of sucrose per 5 mL.

Clinical studies of nitazoxanide did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. In general, the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy in elderly patients should be considered when administering nitazoxanide.
