Is It Safe to Take a Ginkgo Biloba Tinnitus Supplement If You’re on a Blood Thinner or Aspirin?

This article is not a substitute for warfarin, aspirin, another anticoagulant/antiplatelet medication, or any other prescription drug. If you have been diagnosed with a bleeding disorder or a condition requiring blood-thinning medication, talk to your doctor or pharmacist before starting any tinnitus or hearing supplement, and never stop or change a prescribed medication based on this article.
Ginkgo biloba is one of the most common ingredients in tinnitus and hearing supplements, and a genuinely different question from “does it work” is “is it safe to combine with the blood thinner, aspirin, or other medication I’m already taking.” Our general tinnitus FAQ already covers the efficacy side honestly: research from the National Institute on Deafness and Other Communication Disorders finds evidence for supplements, including ginkgo, “weak and inconsistent” for tinnitus specifically. This guide focuses on the safety question that FAQ doesn’t cover: what happens if you combine ginkgo with a blood thinner, and what else is worth knowing before you buy.
Quick Answer
NCCIH states plainly that “ginkgo may increase the risk of bleeding in people who are taking anticoagulant drugs, such as warfarin.” Talk to your doctor or pharmacist before combining a ginkgo-containing hearing supplement with warfarin, aspirin, another blood thinner, or before any planned surgery. NCCIH also notes ginkgo “may be unsafe for use during pregnancy,” and, separately from the safety question, that research does not currently support ginkgo actually relieving tinnitus symptoms.
The Ginkgo and Blood Thinner Interaction
The interaction is straightforward and comes directly from NCCIH, the NIH’s National Center for Complementary and Integrative Health: “Ginkgo may increase the risk of bleeding in people who are taking anticoagulant drugs, such as warfarin.” Ginkgo has mild antiplatelet activity of its own, so adding it to a prescribed blood thinner or a daily aspirin regimen can push clotting function further than a doctor may be actively managing through routine monitoring. NCCIH’s broader guidance on herb-drug interactions also flags that many herbal products, ginkgo among them, can interact with medications “in harmful ways,” and recommends telling a healthcare provider about any herbal product before combining it with a prescription medicine.
This matters specifically for tinnitus and hearing supplements because ginkgo is often included at doses of 120 to 240 mg/day, similar to or higher than doses used in the research NCCIH is describing, not a trace amount buried in a larger blend. If a product’s label lists ginkgo biloba extract, treat it the same way you would treat starting any other ginkgo supplement for the interaction conversation with your doctor.
Surgery and Bleeding Risk
Because ginkgo’s effect on platelets is separate from, and additive to, prescription blood thinners, it is generally sensible to mention any ginkgo-containing supplement to a surgeon or anesthesiologist before a planned procedure, the same way you would mention any other supplement that affects bleeding. If you take aspirin for cardiovascular protection or another antiplatelet medication, the same caution applies even without a separate surgery planned.
Pregnancy and Other Safety Notes
NCCIH separately states that “ginkgo may be unsafe for use during pregnancy. It might cause early labor or extra bleeding during delivery.” For most other adults, NCCIH describes ginkgo leaf extract as “likely to be safe when taken orally in moderate amounts,” with the most common side effects being dizziness, gastrointestinal symptoms, and headache, and notes it has been used safely in research studies lasting as long as six years at typical doses.
What This Means Before You Buy
- On warfarin, aspirin, or another blood thinner: Talk to your doctor or pharmacist before starting any ginkgo-containing tinnitus or hearing supplement.
- Planned surgery or a dental procedure: Mention the supplement to your surgeon or dentist beforehand, the same as any other bleeding-risk supplement.
- Pregnant or breastfeeding: NCCIH’s caution about early labor and delivery bleeding risk is a reason to avoid ginkgo-containing supplements without an OB-GYN’s input.
- Expecting the supplement to meaningfully quiet tinnitus: Set expectations honestly. NCCIH’s own review found ginkgo not helpful for relieving tinnitus symptoms specifically, a limitation that exists independent of the interaction question above.
Bottom Line
Ginkgo biloba, a common ingredient in tinnitus and hearing supplements, carries a real, NCCIH-documented bleeding-risk interaction with warfarin and other anticoagulants, and a separate pregnancy caution. Anyone on a blood thinner, taking daily aspirin, or facing a planned surgery should talk to a doctor or pharmacist before starting one of these products, on top of the already weak evidence that ginkgo meaningfully relieves tinnitus symptoms in the first place.
Frequently Asked Questions
Q: Can I take a ginkgo-based tinnitus supplement if I’m on warfarin?
A: Talk to your doctor or pharmacist first. NCCIH states that ginkgo may increase bleeding risk in people taking anticoagulants like warfarin, and your doctor may want closer monitoring or may advise against it.
Q: Is it safe to take a ginkgo supplement with daily aspirin?
A: Ask your doctor or pharmacist before combining them. Ginkgo has its own mild antiplatelet effect, which can add to aspirin’s blood-thinning effect.
Q: Should I stop a ginkgo supplement before surgery?
A: Mention it to your surgeon or anesthesiologist during pre-op screening, the same way you would disclose any other supplement affecting bleeding, and follow their specific timing instructions.
Q: Does ginkgo actually help tinnitus?
A: The evidence doesn’t currently support it. NCCIH’s review found research “suggests that ginkgo is not helpful…for relieving symptoms of tinnitus.” See our general tinnitus FAQ for more on what the evidence does and doesn’t support.
