Drug Interaction Report

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with nitazoxanide may increase the free plasma concentrations of drugs and/or their active metabolites that are highly bound to plasma proteins. The pharmacologic effects of some drugs may be increased by this interaction. The proposed mechanism is competitive displacement from protein binding sites by tizoxanide, the active metabolite of nitazoxanide that is greater than 99.9% bound to plasma proteins.

MANAGEMENT: Caution is advised when other highly protein-bound drugs are used with nitazoxanide, particularly those with a narrow therapeutic index. Patients should be monitored more closely following the addition or withdrawal of nitazoxanide. When performing therapeutic drug monitoring, total plasma concentrations should be interpreted cautiously due to the possibility of increased free (unbound) drug.

Food can enhance the levels of nitazoxanide in your body. Nitazoxanide should be taken just after eating food. Do not take it on an empty stomach. This will make it easier for your body to absorb the medication.
