How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
What happens
Increased everolimus exposure
Interaction Deep Dive
Avoid coadministration of everolimus with a dual strong CYP3A4 and P-gp inhibitor due to the potential for elevated everolimus exposure21. Everolimus Cmax, AUC, and half-life increased after coadministration with ketoconazole, a strong CYP3A4 and P-gp inhibitor. If concurrent therapy is necessary in transplant recipients, closely monitor everolimus whole blood trough levels 3.
Why it happens (mechanism)
Inhibition of CYP3A4-mediated metabolism of everolimus; inhibition of P-gp mediated efflux transport of everolimus
Literature reports
2 reports — tap to read
a) A 78-year-old female heart transplant recipient receiving everolimus-based immunosuppressive therapy for 11 years (1 mg every 12 hours) with stable trough levels experienced an 11.4-fold increase in everolimus (greater than 20 nanograms (ng)/mL) 4 days following initiation of clarithromycin (500 mg ever 12 hours) for the treatment of pneumonia. Despite a reduction in everolimus to 0.25 mg every 12 hours, her everolimus level remained elevated (18.59 ng/mL). Upon discontinuation of clarithromycin, the everolimus Cmin returned to a stable level of 8.53 ng/mL. The patient did not experience any adverse events 4.
b) Coadministration of 2 mg everolimus and multiple doses of 200 mg ketoconazole twice daily for 5 days (a strong CYP3A4 inhibitor and P-gp inhibitor) in healthy volunteers increased the everolimus Cmax by 3.9-fold, AUC by 15-fold, and half-life by 89%, as compared with everolimus administered alone 3.
