What this interaction means in plain words
Everolimus and Tocilizumab 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, plus possible IL-6 blockade reversing cytokine-mediated CYP3A4 suppression.
