Ginkgo biloba can increase bleeding risk when taken with which drug types?

• A. Beta blockers
• B. Statins
• C. Diuretics
• D. Antiplatelet or anticoagulant drugs (e.g., warfarin, aspirin)

Answer: (D)

Ginkgo biloba can affect how the blood clots by reducing platelet function, which can increase the risk of bleeding. When this herb is taken with drugs that already decrease clotting—antiplatelet or anticoagulant medications such as aspirin or warfarin—the effects can add up, leading to a higher chance of bleeding events like easy bruising, longer nosebleeds, or more serious hemorrhages. That’s why this combination is the one most likely to raise bleeding risk.

Beta blockers, statins, and diuretics don’t directly impair platelet function or coagulation, so they don’t have the same additive bleeding risk with ginkgo. If you’re on an antiplatelet or anticoagulant, it’s important to discuss ginkgo use with a clinician and monitor for signs of bleeding.
