GRAPEFRUIT JUICE AND TACROLIMUS

Medical Diagnosis and Drugs, Medications
Grapefruit juice can markedly increase the serum levels of tacrolimus (by up to 400% in one study).
Tacrolimus levels and effects (e.g. on renal function) should be monitored as a matter of routine, but it is advisable to increase monitoring if grapefruit juice is started or stopped, or avoid the combination.
