Relevance: 26.10.2022 Reviewer: Shkutko P.M., M.D., in

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.

Consumer:

Deferasirox may increase the blood levels and effects of acetaminophen. 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 deferasirox may increase the plasma concentrations of drugs that are substrates of the CYP450 1A2 isoenzyme. The mechanism is decreased clearance due to inhibition of CYP450 1A2 activity by deferasirox. In a study of healthy volunteers, administration of the CYP450 1A2 substrate theophylline (120 mg single dose) in combination with deferasirox (repeated dosing of 30 mg/kg/day) resulted in an approximate doubling of theophylline systemic exposure (AUC) and elimination half-life.

MANAGEMENT: Caution is advised if deferasirox must be used concurrently with medications that undergo metabolism by CYP450 1A2, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever deferasirox is added to or withdrawn from therapy.
