Interactions between your drugs

Moderate

tacrolimus topical ribociclib

Applies to: Protopic (tacrolimus topical) and ribociclib

Consumer information for this interaction is not currently available.

MONITOR: Theoretically, coadministration with CYP450 3A4 inhibitors may increase the plasma concentrations of topical tacrolimus. The proposed mechanism involves inhibition of CYP450 3A4-mediated metabolism of tacrolimus, which is primary metabolized by this isoenzyme. However, systemic exposure from topical tacrolimus is reported to be minimal (less than 1 ng/mL) and so clinically significant drug interactions are not expected. Nevertheless, the possibility of an interaction cannot be ruled out.

MANAGEMENT: According to the manufacturer, caution is advised if topical tacrolimus is prescribed with CYP450 3A4 inhibitors. Patients should be monitored for systemic tacrolimus adverse effects including immunosuppression, infection, hyperkalemia, malignancy, nephrotoxicity, neurotoxicity, and hypertension.

Drug and food interactions

Moderate

ribociclib food

Applies to: ribociclib

Patients should not consume pomegranates, pomegranate juice, grapefruit, or grapefruit juice during treatment with ribociclib unless directed otherwise by your doctor. Pomegranate juice or grapefruit juice can increase the blood levels of ribociclib. You may be more likely to experience side effects such as nausea; vomiting; diarrhea; loss of appetite; abdominal pain; mouth sores; hair loss; weakness; and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems, and infections. 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.
