Efavirenz and Rilpivirine: interaction and safety
This source-based reference is not a personal treatment recommendation. The relevance and management of an interaction depend on the exact products, route, dose and clinical situation.
Interaction mechanism
Efavirenz may reduce rilpivirine exposure; combining NNRTIs has no established benefit.
Clinical significance and safety
Oral rilpivirine should not be combined with efavirenz. The labels advise against NNRTI coadministration, and reduced rilpivirine exposure can compromise treatment; an HIV specialist should select the complete regimen.
Using this information
