Summary
Nevirapine may lower ibrutinib exposure through CYP3A4 induction, potentially reducing efficacy. Strong inducers cause a very large decrease, and nevirapine is expected to have a smaller effect.
What this interaction means in plain words
Ibrutinib and Nevirapine 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.
Ibrutinib belongs to Oncology; Nevirapine belongs to Anti Virals.
Why it happens
Nevirapine induces CYP3A4, increasing ibrutinib first-pass and systemic metabolism.
What to do
Avoid if possible and choose a non-inducing antiretroviral. If combined, monitor for loss of ibrutinib response.
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?
- What early warning signs should I watch for, and what should I do if they appear?
