Edit list (add/remove drugs)

Interactions between your drugs

Moderate

everolimus erdafitinib

Applies to: Afinitor Disperz (everolimus) and erdafitinib

GENERALLY AVOID: Coadministration with erdafitinib may increase the plasma concentrations of drugs that are substrates of the P-glycoprotein (P-gp) efflux transporter, resulting in increased toxicity of these drugs. In vitro, erdafitinib has been shown to be an inhibitor of P-gp. However, no pharmacokinetic data are available from drug interaction studies.

MANAGEMENT: Concomitant use of erdafitinib and P-gp substrates should generally be avoided. If concomitant use is required, administer erdafitinib at least 6 hours before or after administration of P-gp substrates with narrow therapeutic ranges.

Drug and food interactions

Moderate

everolimus food

Applies to: Afinitor Disperz (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.

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.
