With basiliximab induction: initially 0.15-0.2mg/kg/day; give first dose prior to or within 48hrs after transplantation; but may be delayed until renal function has recovered; without induction (pre-op): 0.1mg/kg/day; give dose within 12hrs prior to reperfusion when used with MMF and corticosteroids; without induction (post-op): 0.2mg/kg/day; give first dose within 12hrs after reperfusion but not less than 4hrs after pre-op dose when used with MMF and corticosteroids. Black patients may require higher doses. Renal or hepatic impairment: use lowest effective dose. See full labeling.

Astagraf Xl Warnings/Precautions

Warnings/Precautions

Not interchangeable or substitutable with tacrolimus extended-release or immediate-release products. Not indicated for use in liver transplantation. Increased risk of lymphomas and other malignancies (eg, skin). Avoid sun, UV light. Increased risk of infections (eg, bacterial, viral, fungal, protozoal, cytomegalovirus), opportunistic infections including polyoma virus. Monitor Epstein-Barr virus serology, development of infections during therapy. Risk of new onset diabetes after transplant (esp. Hispanic and black patients); monitor blood glucose. Avoid in congenital long QT syndrome. CHF, bradyarrhythmias, concomitant antiarrhythmic drugs, or electrolyte disturbances; consider obtaining ECGs and monitor electrolytes periodically. Hepatic or renal impairment; monitor and consider dose reduction. Obtain tacrolimus whole blood concentrations (see full labeling), serum creatinine, serum potassium, and fasting glucose periodically. Risk for thrombotic microangiopathy (including hemolytic uremic syndrome and thrombotic thrombocytopenic purpura) esp. in those with severe infections, GVHD, MLA mismatch. Complete required immunizations prior to transplantation and treatment. Elderly. Labor & delivery.

Astagraf Xl Interactions

Interactions

Concomitant sirolimus (in liver/heart transplant), live vaccines: not recommended. Concomitant mTOR inhibitors (eg, sirolimus, everolimus) may increase risk of thrombotic microangiopathy. Concomitant mycophenolic acid (MPA) products; monitor and reduce the dose of these as needed. Concomitant strong CYP3A4 inhibitors/inducers or substrates: must adjust dosing regimen, closely monitor tacrolimus blood concentrations and for QT prolongation. Caution with potassium-sparing diuretics, ACEIs, ARBs. Avoid grapefruit/grapefruit juice, alcohol. Additive nephrotoxicity with aminoglycosides, ganciclovir, amphotericin B, cisplatin, ritonavir; if concomitant use, monitor renal function and tacrolimus blood levels; adjust doses of both drugs. May be potentiated by calcium channel blockers (eg, verapamil, diltiazem, nifedipine, nicardipine), antifungals (eg, voriconazole, posaconazole, itraconazole, fluconazole, ketoconazole), macrolides (eg, troleandomycin, clarithromycin, erythromycin), lansoprazole, omeprazole, chloramphenicol, cimetidine, clotrimazole, amiodarone, danazol, ethinyl estradiol, protease inhibitors (eg, nelfinavir, telaprevir, boceprevir, ritonavir), nefazodone, letermovir, schisandra sphenanthera extracts, magnesium-aluminum-hydroxide, metoclopramide. May be antagonized by carbamazepine, phenobarbital, phenytoin, rifabutin, rifampin, St. Johns wort, methylprednisolone, prednisone, caspofungin. Monitor closely with direct acting antiviral therapy; may need to adjust dose.
