Tramadol (Contramal Retard 100 mg) and Darunavir: 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 can increase tramadol exposure.
Clinical significance and safety
For ritonavir-boosted darunavir (PREZISTA/ritonavir), tramadol requires review and monitoring for increased adverse effects. The full opioid and sedative regimen matters; do not change tramadol or HIV treatment independently.
