Is Resveratrol Safe If You Take Eliquis?
In our latest question and answer, the pharmacist discusses the potential interaction between resveratrol and Eliquis.
Can I take resveratrol 500 mg capsules if I take Eliquis?
Aug 06, 2023- There is a theoretical interaction between resveratrol and Eliquis because resveratrol may slow how your body breaks down the blood thinner, but human studies show this effect is unlikely to be significant at typical supplement doses.
- Talk with your doctor before taking resveratrol with Eliquis to make sure it's safe for you.
Quick Answer
Based on available information, it is unlikely that taking resveratrol capsules would significantly affect the metabolism of apixaban (Eliquis), a medication predominantly metabolized by the CYP3A4 enzyme, but caution is still recommended.
Detailed Answer
There is a theoretical interaction between resveratrol and apixaban (Eliquis) which arises from resveratrol's demonstrated inhibition of the CYP3A4 enzyme in some laboratory studies. CYP3A4 is responsible for the metabolism of Eliquis.
The complete mechanism of this interaction is as follows:
- When resveratrol inhibits CYP3A4, it can lead to a decrease in Eliquis breakdown within the liver.
- This reduction in metabolism might result in higher Eliquis levels in the bloodstream than expected from the dose.
- As a result, there could be an increased risk of Eliquis-related side effects or bleeding due to elevated drug levels.
However, it is important to note that clinical research in humans indicates that even quite high resveratrol doses (one study evaluated 3000 mg daily for 8 weeks) haven't necessitated dosage adjustments for drugs metabolized by CYP3A4 (i.e., no significant effect on the enzyme has been seen).
This suggests that resveratrol's effects on actual drug metabolism may differ from laboratory (i.e., in vitro) results.
While caution is still advised, overall, usual resveratrol dosages in dietary supplements are unlikely to significantly impact Eliquis metabolism.
As always, be sure to speak with your doctor before making any changes to your medication regimen.
The inhibition of CYP3A4 by resveratrol appears primarily based on small-scale laboratory studies and hasn't been widely confirmed in human populations.
