Interactions between your drugs

Moderate

everolimus elagolix

Applies to: everolimus and elagolix

MONITOR: Coadministration with inducers of CYP450 3A4 and/or P-glycoprotein (P-gp) may decrease the blood concentrations and pharmacologic effects of everolimus. In a study of healthy volunteers, multiple doses of the potent inducer rifampin increased the oral clearance of everolimus by threefold, representing mean decreases in peak blood concentration (Cmax) and systemic exposure (AUC) of 58% and 63%, respectively. The extent to which other inducers of CYP450 3A4 interact with everolimus is unknown.

MANAGEMENT: Some manufacturers recommend avoiding concomitant use of everolimus with moderate CYP450 3A4 and/or P-gp inducers such as bosentan, efavirenz, and nevirapine. If concomitant use is required, a dose adjustment of everolimus should be considered to achieve the recommended therapeutic range for the condition being treated. Please refer to the manufacturer's labeling for specific dosing information. Everolimus whole blood trough levels should be closely monitored during treatment, particularly 2 weeks after a dose increase and 2 weeks after discontinuation of the inducer.

Drug and food interactions

Moderate

everolimus food

Applies to: everolimus

GENERALLY AVOID: Grapefruit juice may significantly increase the plasma concentrations of orally administered everolimus. The mechanism is inhibition of CYP450 3A4 and P-glycoprotein activity in the gut wall by certain compounds present in grapefruit.

MANAGEMENT: Patients treated with everolimus should avoid consumption of grapefruit and grapefruit juice.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
