Dexamethasone (Deksamet 4 mg) 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
Repeated systemic dexamethasone induces CYP3A and reduces rilpivirine exposure.
Clinical significance and safety
Systemic dexamethasone treatment beyond a single dose is contraindicated with oral rilpivirine. A one-off dose is a different label situation, so the prescriber must review duration and the exact HIV regimen.
