Interactions between your drugs

Moderate

mefloquine nitazoxanide

Applies to: mefloquine and nitazoxanide

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.
