Tylenol Severe Allergy and Varubi (Rolapitant Injection)

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Rolapitant may increase the blood levels and effects of diphenhydrAMINE, even after you have stopped taking rolapitant for a while. 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.

MONITOR: Coadministration with rolapitant may increase the plasma concentrations of drugs that are substrates of the CYP450 2D6 isoenzyme. Rolapitant is a moderate CYP450 2D6 inhibitor, with inhibitory effect lasting at least 7 days after a single dose. When a 30 mg dose of dextromethorphan, a CYP450 2D6 probe substrate, was administered with a 180 mg dose of rolapitant on day 1 of a pharmacokinetic study, dextromethorphan peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 120% and 160%, respectively. When dextromethorphan was administered on day 8 without rolapitant, Cmax and AUC increased by 180% and 230%, respectively. The duration of CYP450 2D6 inhibition was not studied beyond 7 days and may last longer.

MANAGEMENT: Caution is advised when rolapitant is prescribed with drugs that are significantly metabolized 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as well as clinical and laboratory monitoring may be appropriate for some drugs whenever rolapitant is added to or withdrawn from therapy.
