MemoPryl With Blood Thinners: Is It Safe to Combine?
MemoPryl with blood thinners is a combination to ask your prescriber about first. One of its six named herbs, ginkgo, is linked to more bleeding when taken with warfarin. St. John's wort can also change how warfarin works. Keep taking your blood thinner as directed.

The question01
Can you take MemoPryl with blood thinners?
You should not take MemoPryl with blood thinners unless the prescriber who ordered the blood thinner says it is fine. No study tested the capsule with these drugs.
The worry comes from the ginkgo named on the list. Ginkgo with warfarin is linked to a higher chance of major bleeding than warfarin alone (NCCIH, herb-drug interactions).
Why02
Why does ginkgo raise bleeding risk with warfarin?
Ginkgo raises bleeding risk because it may make blood less likely to clot. Blood thinners already lower clotting on purpose, so the two effects can add up.
Ginkgo is flagged for bleeding in the cancer-center and European monograph summaries (EMA/HMPC, Ginkgo monograph) (MSK, Ginkgo).
| Name | Concern |
|---|---|
| Ginkgo biloba leaf | More bleeding |
| St. John's wort | Can change warfarin's effect |
| Phosphatidylserine | Possible bleeding risk |
Warning signs03
What are the warning signs of bleeding to watch for?
The warning signs of bleeding are unusual bruising, nosebleeds that will not stop, black stools or blood in urine. Call your doctor for these.
A sudden severe headache, confusion or weakness on one side needs 911.
- Daily life disruptedForgetting recently learned things, repeating questions, relying on notes for everything
- Lost in familiar placesGetting lost in your own neighborhood or on a usual route
- Trouble with usual tasksCooking, paying bills or using a phone becomes hard
- Words and namesUsing odd words for familiar things, or forgetting a close relative's name
- Mood or personality changeWithdrawal, suspicion, new anxiety or poor judgment
See a doctorAny of these signs, or memory trouble that is getting worse, is a reason to see a doctor. Early diagnosis helps with treatment and planning. A supplement should not delay it.
Go nowSudden confusion, trouble speaking, weakness on one side of the body, or a severe sudden headache can be a stroke or another emergency. Call 911 or go to an emergency room.

FAQ06
Questions about ginkgo and blood thinners
Does aspirin count as a blood thinner for supplement advice?
Treat it as one for this purpose, yes. Daily aspirin also affects bleeding, so tell the pharmacist about it. Ask before combining it with ginkgo.
Does a blood thinner change when ginkgo should stop before an operation?
The European monograph says to stop it 3 to 4 days before surgery (EMA/HMPC, Ginkgo monograph). Your surgical team decides your timing, so tell them about every supplement.
Can I stop my blood thinner to try a supplement?
No. Never stop or change a prescribed blood thinner on your own. Stopping can raise the risk of clots and stroke. Talk to the prescriber first.
