Summary
Rifampin is a potent CYP3A inducer and strong inducers substantially reduce ixazomib exposure. This may lead to treatment failure.
What this interaction means in plain words
Ixazomib and Rifampin 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
Rifampin induces CYP3A4 via PXR activation, increasing ixazomib clearance.
What to do
Avoid concomitant use per ixazomib labeling; use a non-inducing anti-infective if possible.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
