Organ rejection prophylaxis in allogeneic hepatic transplant patients, in combination with corticosteroids; or in cardiac and renal transplant patients in combination with corticosteroids, azathioprine, or mycophenolate mofetil (MMF).
If previously on IV infusion, initial oral dose may be given 8–12hrs post infusion. Adjunct therapy with corticosteroids is recommended early post-transplant. Hepatic, cardiac: give no sooner than 6hrs after transplantation. Renal: may be given within 24hrs of transplantation but should be delayed until renal function has recovered. Hepatic: initially 0.1–0.15mg/kg/day in two divided dose every 12hrs. Cardiac: initially 0.075mg/kg/day in two divided doses every 12hrs. Renal: initially 0.2mg/kg/day in two divided doses every 12hrs in combination with azathioprine; or 0.1mg/kg/day in two divided doses every 12hrs in combination with MMF and IL-2 receptor antagonist; black patients may require higher doses. Renal or hepatic impairment: use lowest effective dose (see full labeling). Post-op oliguria: may delay therapy until renal function recovers.
If previously on IV infusion, initial oral dose may be given 8–12hrs post infusion. Adjunct therapy with corticosteroids is recommended early post-transplant. Hepatic: initially 0.15–0.2mg/kg/day in two divided doses every 12hrs. Give no sooner than 6hrs after transplantation.

Hepatic or renal impairment; monitor and consider dose reduction. Obtain tacrolimus blood concentrations, serum creatinine, potassium, and fasting glucose periodically. Discontinue or reduce dose if myocardial hypertrophy occurs. Pregnancy (Cat.C), nursing mothers: not recommended.
Concomitant sirolimus, live vaccines: not recommended. Concomitant mycophenolic acid (MPA) products: can increase MPA exposure after crossover from cyclosporine to tacrolimus; monitor and adjust doses.
