Interactions between your drugs
troleandomycin telithromycin
Applies to: Tao (troleandomycin), telithromycin
MONITOR: Coadministration with telithromycin may increase the plasma concentrations of drugs that are substrates of the CYP450 3A4 isoenzyme. The mechanism is decreased clearance due to inhibition of CYP450 3A4 activity by telithromycin.
MANAGEMENT: Caution is advised if telithromycin must be used concurrently with medications that undergo metabolism by CYP450 3A4, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever telithromycin is added to or withdrawn from therapy.
