Warfarin Interaction

Cranberry products can interact with warfarin, increasing INR levels and the risk of bleeding. Monitor INR closely if consuming cranberry products while taking warfarin.

Concurrent use of cranberry products with warfarin, an anticoagulant medication, can lead to an increased international normalized ratio (INR), indicating a greater risk of bleeding complications. This interaction occurs because cranberry components can inhibit the metabolism of warfarin, leading to higher levels of the drug in the bloodstream. Symptoms of increased bleeding risk include easy bruising, prolonged bleeding from cuts, nosebleeds, blood in urine or stool, and severe headaches. Monitoring of INR is crucial when cranberry products are consumed alongside warfarin.
