Interactions between your drugs

Moderate

eltrombopag momelotinib

Applies to: Alvaiz (eltrombopag) and momelotinib

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inhibitors of organic anion transporting polypeptides (OATP) 1B1 and/or 1B3 may increase the plasma concentrations and effects of momelotinib, which is a substrate of these hepatic uptake transporters. In a phase I study, coadministration of momelotinib (200 mg) with a single dose of the OATP1B1/1B3 inhibitor rifampin (600 mg) increased the peak plasma concentration (Cmax) and systemic exposure (AUC) of momelotinib by 40% and 57%, respectively. The Cmax and AUC of the active metabolite of momelotinib, M21, was also increased, by 6% and 12%, respectively.

MANAGEMENT: Caution is advised if momelotinib is used in combination with inhibitors of OATP1B1 and/or 1B3. Dosage adjustments of momelotinib may be required. Patients should be advised to report any momelotinib-related adverse reactions such as bacterial or viral infection, thrombocytopenia, neutropenia, hepatotoxicity, thrombosis, and adverse cardiovascular events.

Drug and food/lifestyle interactions

Moderate

eltrombopag food/lifestyle

Applies to: Alvaiz (eltrombopag)

Food may reduce the absorption and blood levels of eltrombopag. In addition, minerals such as aluminum, calcium, iron, magnesium, and zinc can also interfere with eltrombopag absorption into the bloodstream, which may make the medication less effective in treating your condition. You should take eltrombopag on an empty stomach one hour before or two hours after a meal. Eltrombopag should also be taken at least 2 hours before or 4 hours after products like antacids, mineral supplements, dairy products, and fortified juices. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. 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.
