Consumer:Ritonavir may increase the blood levels and effects of promethazine. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: Coadministration with ritonavir may increase the plasma concentrations of drugs that are substrates of the CYP450 2D6 isoenzyme. The mechanism is decreased clearance due to competitive inhibition of CYP450 2D6 activity by ritonavir. The systemic exposure (AUC) of some coadministered drugs has been reported to increase by up to twofold.
MANAGEMENT: Caution is advised if ritonavir must be used concurrently with medications that undergo metabolism by CYP450 2D6, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever ritonavir is added to or withdrawn from therapy.
