This page explains what happens if Aspirin and Diclofenac are taken together, according to official sources.
Severe peptic ulcer and gastrointestinal hemorrhage
Combining aspirin with diclofenac exponentially increases the risk of gastrointestinal ulcers, erosions, and life-threatening bleeding.
Avoid concurrent use. If low-dose aspirin is required for cardioprotection, avoid systemic NSAIDs like diclofenac; choose paracetamol instead.
Talk to your doctor or pharmacist about these two medicines; don't stop a prescribed medicine on your own.
