General safety of taking Eliquis and magnesium
Eliquis, the brand name for apixaban, is a direct-acting oral anticoagulant (DOAC) used to prevent and treat blood clots. Unlike older anticoagulants like warfarin, Eliquis has fewer dietary and supplement restrictions, making it a more convenient option for many patients. For most common forms of magnesium, such as magnesium citrate, magnesium oxide, magnesium glycinate, and magnesium sulfate, drug interaction databases report no known significant interactions with Eliquis. This means that for many individuals, taking these types of magnesium supplements alongside their prescribed Eliquis is not expected to cause issues with bleeding or drug efficacy.
The critical exception: Magnesium salicylate
While most magnesium supplements are not known to interact with Eliquis, there is one significant exception: magnesium salicylate. Salicylates are compounds that can thin the blood, and when combined with Eliquis, the risk of bleeding can increase substantially. Magnesium salicylate should be avoided by anyone taking Eliquis unless specifically instructed and closely monitored by a healthcare professional. It is imperative for patients to read supplement labels carefully to identify the specific form of magnesium contained within the product.
Important considerations when combining Eliquis and supplements
Even with safe combinations, there are important guidelines for managing your medication and supplements to maximize safety. A common practice is to space out the intake of your medication and any supplements to avoid potential absorption issues. Although Eliquis can be taken with or without food and its absorption is generally not affected, separating doses can be a sensible precaution. Furthermore, staying hydrated and monitoring for any unusual symptoms can help identify any potential, even if rare, side effects.
List of supplements to discuss with your doctor when on Eliquis
- High-dose fish oil: While fish oil from food is fine, concentrated supplements may increase bleeding risk.
- Vitamin E: High doses of this vitamin can also increase bleeding risk.
- Herbal supplements: Certain herbs, such as turmeric, ginger, ginkgo biloba, and St. John's wort, can either increase bleeding risk or decrease the effectiveness of Eliquis. St. John's wort, in particular, should be avoided as it can significantly reduce Eliquis's efficacy.
- Grapefruit and grapefruit juice: These can increase the concentration of Eliquis in the bloodstream, raising the risk of bleeding.
- NSAIDs (nonsteroidal anti-inflammatory drugs): Pain relievers like ibuprofen or naproxen can increase the risk of bleeding when taken with Eliquis. Acetaminophen is generally considered a safer alternative for pain relief.
Comparing Different Magnesium Forms with Eliquis
| Feature | Magnesium Citrate | Magnesium Oxide | Magnesium Salicylate |
|---|---|---|---|
| Common Use | Laxative, constipation relief | Heartburn, magnesium deficiency | Pain relief, inflammation |
| Known Eliquis Interaction | No significant interaction | No significant interaction | Increased bleeding risk |
| Primary Risk | Laxative effects, GI upset | Laxative effects, GI upset | High bleeding risk when combined |
| Recommendation with Eliquis | Generally considered safe to take | Generally considered safe to take | Avoid unless directed by a doctor |
The risk of magnesium toxicity (hypermagnesemia)
While taking a standard magnesium supplement is generally safe, over-consumption of magnesium can lead to a condition known as hypermagnesemia, where magnesium levels in the blood become too high. This is particularly a risk for individuals with impaired kidney function, as the kidneys are responsible for excreting excess magnesium. Symptoms of hypermagnesemia can range from mild (nausea, confusion, weakness, low blood pressure) to severe (drowsiness, muscle paralysis, and cardiac arrhythmia), and prompt medical attention is necessary.
Conclusion
The question of whether Eliquis and magnesium can be taken together highlights the importance of understanding specific drug interactions, not just assuming all supplements are benign. While most common types of magnesium, such as citrate and oxide, do not pose a known threat, the interaction with magnesium salicylate is a critical safety issue that must be addressed with caution. Ultimately, patients should view any supplement or over-the-counter medication as a potential interaction and discuss it with their healthcare provider or pharmacist. This proactive approach helps to ensure the continued effectiveness of Eliquis and, most importantly, protects against increased bleeding risk.

Your healthcare provider is your best resource
Before adding any supplement, including magnesium, to your regimen while on Eliquis, a consultation with your doctor is non-negotiable. They can provide personalized advice based on your full medical history, current medications, and any underlying conditions like kidney disease. By taking this step, you can safely and confidently manage your health without compromising the efficacy of your anticoagulant therapy.
