Summary
Nevirapine may lower bedaquiline concentrations, possibly reducing efficacy against drug-resistant tuberculosis and risking resistance.
What this interaction means in plain words
Bedaquiline 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.
Bedaquiline belongs to Anti Bacterial; Nevirapine belongs to Anti Virals.
Why it happens
CYP3A4 induction by nevirapine increases bedaquiline clearance.
What to do
Avoid long-term coadministration with strong or moderate CYP3A4 inducers. Use a non-inducing antiretroviral regimen and monitor microbiological response.
