moderate Known Drug Interaction
Drugs that Interfere with Hemostasis (e.g., NSAIDs, Aspirin, and Warfarin) Serotonin release by platelets plays an important role in hemostasis. Epidemiological studies of the case-control and cohort design that have demonstrated an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of upper gastrointestinal bleeding have also shown that concurrent use of an NSAID or aspirin may potentiate this risk of bleeding.
Recommendation: Watch for signs of unusual bruising or bleeding and talk to your doctor about the risks of this combination.

Aspirin is a common medicine used to relieve minor pain. It can also be prescribed by your doctor for other uses.
Venlafaxine is a medication used to treat depression. It helps to improve your mood by affecting certain chemicals in the brain.
Aspirin is used to temporarily relieve minor aches and pains. However, it works slowly. It will not quickly relieve headaches or other symptoms that need immediate relief. Ask your doctor about other uses for this medicine.
Venlafaxine is used to treat major depressive disorder. This condition can cause a persistent feeling of sadness or loss of interest in daily activities. It may also help maintain improvement in patients with recurrent depression.
Aspirin belongs to a class of drugs called NSAIDs and antiplatelets. It works by reducing substances in the body that cause pain and inflammation. It also helps to prevent blood clots.
Venlafaxine is a serotonin-norepinephrine reuptake inhibitor (SNRI). It works by increasing the levels of serotonin and norepinephrine in the brain. These chemicals help regulate mood and can be low in people with depression.

How to Read This aspirin vs venlafaxine Comparison
aspirin is classified in the Antiplatelet / NSAID drug class, while venlafaxine sits within the Serotonin-Norepinephrine Reuptake Inhibitor (SNRI) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are split between OTC and prescription status, which affects access and supervision.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, aspirin has 134,578 submissions while venlafaxine has 19,671. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to both drugs interfere with how blood cells called platelets work, which increases the risk of serious bleeding in the stomach or other areas.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
