Summary
Both agents suppress immune function, so concurrent use increases the risk of serious infection and possibly malignancy. Tacrolimus is a CYP3A4 substrate and combined mTOR inhibitor and calcineurin inhibitor use can also enhance renal toxicity.
What this interaction means in plain words
Tacrolimus and Temsirolimus can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Why it happens
Additive immunosuppression through calcineurin and mTOR pathway inhibition.
What to do
Avoid unless clearly necessary; if combined, monitor for infection, renal function and tacrolimus trough levels.
