Warfarin (Coumadin 5 mg) and Venetoclax: 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
A clinical study found increased warfarin exposure with venetoclax.
Clinical significance and safety
When Warfarin (Coumadin 5 mg) and Venetoclax are used together, INR should be monitored more closely. The interaction study was small and did not assess venetoclax at steady state, which is why the product information recommends careful anticoagulation monitoring. Report bleeding symptoms and do not change the warfarin dose yourself.
Using this information
