Documented concern based on cited evidence — not a personalized safety check, not medical advice, and not a decision to combine or avoid. That decision belongs with your prescriber.
Documented concern — monitor and disclose
Clinically relevant documented concern. Disclose the supplement to your clinician and keep monitoring in place.
Mechanism and evidence
The bleeding mechanism documented for ginkgo with warfarin applies without an INR to watch; DOAC monitoring is harder, which raises practical caution.
Evidence tier: label-mechanistic
The tier names the strongest cited study design. Some anchors studied the supplement on its own, or a related drug in the same class — in those pairs the grade rests on that evidence plus established pharmacology, as agreed with our medical reviewer.
What to discuss with your prescriber
- Avoid ginkgo on a DOAC unless your prescriber says otherwise.
- Bleeding signs deserve a prompt call.
