Medicine caution
CoQ10 warfarin: what is reported and who to ask
CoQ10 warfarin is a pairing MSK flags: it reports that coenzyme Q10 may increase bleeding risk with warfarin and may work against it. Flow Nerves names coenzyme Q10 (ubiquinone) and prints no amount. If you take warfarin, ask your prescriber or pharmacist; never change a prescribed medicine on your own.

What is reported
What is the CoQ10 warfarin interaction?
CoQ10 warfarin is a reported interaction: MSK says CoQ10 has been reported to increase bleeding risk with warfarin and may antagonize it (MSK, Coenzyme Q10).
Those two statements point in different directions, and the page gives no dose and does not name the form. It is a caution to bring to a pharmacist, not an instruction to change a medicine. Do not stop, skip or change warfarin because of a supplement.
| Medicine | Caution |
|---|---|
| Warfarin | Reported bleeding risk; may antagonize its effect (MSK, Coenzyme Q10) |
| Chemotherapy and radiation | May reduce their effect |
| Theophylline | Slows its clearance |
| Other blood thinners | We found no source |
Monitoring
Why does a pharmacist ask about CoQ10 if you take warfarin?
Because a supplement that may change how warfarin works is something your prescriber needs to know about.
We found no source on blood-test timing or monitoring with CoQ10, so we give none; that is a clinician's call. NIH says to tell every provider about every supplement and keep a record (NIH ODS, Dietary Supplements: What You Need to Know). Bring the bottle, since it names six ingredients and prints no amount.
Warning signs
Which signs after adding a supplement need a call?
Unusual bruising, nosebleeds or blood in urine or stool need a call to your clinician or pharmacist.
- Sudden numbness or weakness on one side, trouble speaking, seeing or walkingCall 911. CDC lists these as stroke signs.
- Dark urine, yellow skin or eyes, belly pain, fatigueCan be signs of liver trouble, which LiverTox links to turmeric. Stop and get medical care the same day.
- Unusual bruising, nosebleeds or blood in urine or stoolPossible bleeding, especially on a blood thinner (MSK on turmeric and CoQ10). Stop and call your clinician or pharmacist.
- Shaky, sweaty, confused, very hungryPossible low blood sugar if you take diabetes medicine (MSK on alpha lipoic acid): treat it as your care team told you and call them.
- Rash, hives or swellingPossible allergy. Stop and get medical help; swelling of the face or throat or trouble breathing is an emergency.
- Diarrhea, nausea, stomach crampsCommon supplement effects (NIH on magnesium and carnitine). Stop and ask a clinician if they persist.
Signs from (CDC, Stroke signs and symptoms) (LiverTox, Turmeric) (MSK, Alpha-lipoic acid) (NIH ODS, Magnesium). This list is not complete. A supplement is never a reason to wait.

MSK lists nausea, diarrhea, loss of appetite and sleeplessness (MSK, Coenzyme Q10).
Keep taking prescribed medicine. Sudden numbness or weakness, especially on one side, trouble speaking, chest pain or trouble breathing: call 911. Lasting tingling needs a clinician to look for a cause.

FAQ
Flow Nerves questions people ask
Can you take CoQ10 with warfarin?
MSK reports that CoQ10 may increase bleeding risk with warfarin and may antagonize it. Do not change your medicine on your own. Ask your prescriber or pharmacist before adding it, and tell them about every supplement.
Is ubiquinone the same as CoQ10?
Ubiquinone is a form of coenzyme Q10, and it is the form the seller names for Flow Nerves. MSK does not name a form, so we cannot say whether its warfarin report applies to one form more.
How much CoQ10 is in Flow Nerves?
We do not know. The seller prints no milligram amount for any of the six ingredients, and we hold no Supplement Facts panel. Ask for the bottle's panel before you buy.
