This page explains what happens if Diclofenac and Warfarin are taken together, according to official sources.
Major gastrointestinal bleeding risk
Diclofenac erodes gastric mucosa and inhibits platelets, causing severe hemorrhage when taken with warfarin.
Avoid combination. Substitute with paracetamol for analgesia if approved by physician; never self-administer NSAIDs with warfarin.
Talk to your doctor or pharmacist about these two medicines; don't stop a prescribed medicine on your own.
