Darunavir and Rifabutin: 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
The boosted regimen increases rifabutin and active-metabolite exposure.
Clinical significance and safety
For ritonavir-boosted darunavir (PREZISTA/ritonavir), rifabutin requires a specific prescriber-managed plan and toxicity monitoring. This differs from rifampin, which is contraindicated.
