DOSE MODIFICATIONS IN KIDNEY OR LIVER TRANSPLANT:
Patients may require dose adjustments based on everolimus blood concentrations achieved, tolerability, individual response, change in concomitant medications and the clinical situation. Dose adjustments should be based on trough concentrations taken 4 or 5 days after a previous dosing change. Dose adjustment is required if the trough concentration is below 3 ng/mL. The total daily dose should be doubled using the available tablet strengths (0.25 mg, 0.5 mg or 0.75 mg). Dose adjustment is also required if the trough concentration is greater than 8 ng/mL on 2 consecutive measures; the dose should be decreased by 0.25 mg twice daily.
Precautions
US BOXED WARNINGS:
Zortress (R):
- MANAGEMENT OF IMMUNOSUPPRESSION: Only physicians experienced in immunosuppressive therapy and management of transplant patients should use Zortress(R).
