What the FDA labels say
From the Diclofenac (Diclofenac Potassium) label · effective 2025-01-21
Co-morbid conditions such as coagulation disorders or concomitant use of warfarin, other anticoagulants, antiplatelet agents (e.g., aspirin), serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk.
Intervention: Monitor patients with concomitant use of Diclofenac Potassium with anticoagulants (e.g., warfarin), antiplatelet agents (e.g., aspirin), selective serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) for signs of bleeding [see Warnings and Precautions (5.11) ] .
Drugs that Interfere with Hemostasis (e.g. warfarin, aspirin, SSRIs/SNRIs): Monitor patients for bleeding who are concomitantly taking Diclofenac Potassium with drugs that interfere with hemostasis.
From the Venlafaxine (Venlafaxine Hydrochloride) label · effective 2025-01-31
Concomitant use of aspirin, Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), warfarin, and other anticoagulants may add to this risk.

These studies have also shown that concurrent use of an NSAID or aspirin may potentiate this risk of bleeding.
Drugs that Interfere with Hemostasis (e.g., NSAID’s, Aspirin, and Warfarin) Serotonin release by platelets plays an important role in hemostasis.
