Summary
Apalutamide is a strong CYP3A4 inducer and can substantially lower nevirapine concentrations, risking virological failure and resistance. Nevirapine may also affect apalutamide exposure.
What this interaction means in plain words
Apalutamide 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.
Apalutamide belongs to Endocrine; Nevirapine belongs to Anti Virals.
Why it happens
Apalutamide induces CYP3A4 and CYP2B6, increasing nevirapine metabolism.
What to do
Avoid the combination and use an antiretroviral regimen not dependent on these enzymes. If unavoidable, monitor HIV viral load closely.
