Interactions between your drugs

Moderate

chloramphenicol ivermectin

Applies to: chloramphenicol and ivermectin

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of ivermectin and the risk of adverse effects. The proposed mechanism, based on in vitro data, is decreased clearance due to inhibition of CYP450 3A4, the primary isoenzyme responsible for the metabolic clearance of ivermectin.

MANAGEMENT: Caution is advised when ivermectin must be used concomitantly with potent CYP450 3A4 inhibitors. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate whenever a potent CYP450 3A4 inhibitor is added to or withdrawn from therapy.
