How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
Curcumin is the active part of turmeric, often taken as a supplement. When taken with apixaban (Eliquis), a blood thinner, it may cause more of the apixaban to stay in your body. That could raise your chance of bleeding, like easy bruising, nosebleeds, or bleeding that is slow to stop.
I want to be clear that this is a theoretical concern, meaning it is based on how the drugs might behave, not on strong studies in people. Please don't stop either one on your own. Just let your pharmacist or doctor know you take turmeric or curcumin so they can keep an eye on things and manage it safely.
Effect: Curcumin may increase apixaban exposure, raising bleeding risk.
Mechanism: Curcumin is a possible P-glycoprotein inhibitor; apixaban is a P-gp substrate, so reduced efflux may increase apixaban AUC/Cmax. Neither drug requires bioactivation here, so the effect is a straightforward increase in anticoagulant exposure.
- Direction: Increased apixaban effect
- Onset: Unspecified
- Evidence: Theoretical
- Management: Use with caution, particularly with additional bleeding risk factors or other agents raising apixaban levels. Monitor for bleeding; dose may be individualized by the care team.
What happens
Increased exposure of apixaban and an increased risk of bleeding
Interaction Deep Dive
Taking apixaban together with curcumin has the potential to raise apixaban exposure. Exercise caution when combining them, particularly if additional bleeding risk factors are present or if other medications that could elevate apixaban levels are being used1.
Why it happens (mechanism)
Possible inhibition of P-glycoprotein-mediated efflux transport by curcumin
How to manage this interaction
Keep taking both as prescribed unless your prescriber tells you otherwise. This is a theoretical interaction, so the practical steps are mostly caution and awareness.
- Tell your pharmacist and doctor that you take curcumin/turmeric, including the dose and how often.
- Your care team may watch you more closely for bleeding, especially if you have other bleeding risk factors or take other drugs that raise apixaban levels.
- Any apixaban dose changes should be individualized by your care team.
- Report unusual bruising, blood in urine or stool, black stools, or bleeding that won't stop.
Management is individual — confirm any change with your pharmacist or prescriber.
