Can I drink alcohol with Aspirin?

How Aspirin interacts with alcohol

Aspirin (acetylsalicylic acid) irreversibly inhibits COX-1 platelets and damages the gastric mucosal barrier. Alcohol independently irritates the stomach and impairs mucosal repair. Combined, they multiply the risk of GI bleeding — one study found a 6-fold increase in major GI bleeding when both were used heavily. This is especially dangerous for patients taking low-dose aspirin for cardiovascular prevention.

Safety guidance

• Occasional drinking (1 standard drink with a single low-dose aspirin 75–100 mg): low risk for healthy adults with food.
• Daily low-dose aspirin (81 mg for cardioprotection): limit alcohol to ≤1 drink/day for women, ≤2 for men.
• Pain-dose aspirin (325–650 mg every 4–6h): do not combine with alcohol — acute GI bleed risk is highest here.
• Dose-response: each additional daily drink measurably raises GI bleed risk when on aspirin.
• Avoid binge drinking completely while on any dose of aspirin.

When to avoid alcohol completely

• History of peptic ulcer, gastritis, H. pylori infection
• Taking anticoagulants (warfarin, DOACs), other antiplatelet agents, or SSRIs
• Age ≥65 on daily aspirin
• Chronic kidney disease or liver dysfunction
• Active treatment for cardiovascular disease where GI bleed would be catastrophic
