Scope and limitations
Evidence limitations

Limitations have not yet been documented. Personal history, exact amount and timing, other medicines, allergies, and local guidance may change the answer.

Medical Analysis
Mechanism

Ginkgo biloba contains compounds that can inhibit platelet aggregation, which can compound the effects of anticoagulants, leading to an increased risk of bleeding. This effect occurs because Ginkgo affects the coagulation cascade and may alter blood viscosity, thus interfering with normal hemostasis. When taken together, the pharmacodynamic interaction enhances the anticoagulant effect, increasing the likelihood of hemorrhagic events in susceptible populations.

Clinical Impact & Risks

Increased risk of bleeding, including spontaneous bruising, gastrointestinal bleeding, or intracranial hemorrhage.

Management & Recommendations

Patients should be advised to discontinue Ginkgo biloba prior to surgery or if they experience unusual bleeding. Regular monitoring of INR levels may be required in patients using anticoagulants.
