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.
You've been prescribed apixaban (Eliquis), a blood thinner, along with dexamethasone, a steroid. When these two are taken together, there can be a somewhat higher chance of bleeding, especially in the stomach and gut. Steroids like dexamethasone can be a bit rough on the stomach lining, and a blood thinner makes any bleeding harder to stop.
This isn't a reason to panic. Many people take both safely. The main thing is that your care team may watch you a little more closely. Please keep taking both exactly as prescribed, and let your pharmacist or doctor know if you notice black or bloody stools, vomit that looks like coffee grounds, or unusual bruising.
Effect: Increased risk of bleeding, particularly gastrointestinal bleeding (GIB), with concomitant apixaban and oral dexamethasone.
- Direction: Additive/increased bleeding risk (neither drug is a prodrug here).
- Mechanism: Precise mechanism unknown; likely additive mucosal/GI insult from glucocorticoids plus anticoagulant effect.
- Evidence: Probable; cohort data showed higher GIB rates in NOAC users co-prescribed oral glucocorticoids within 60 days, dose-dependent.
- Onset: Unspecified.
- Management: If coadministration is necessary, monitor closely for bleeding, especially at higher glucocorticoid doses and in bleeding-prone patients. Consider GI protection per clinical judgment.

Increased risk of gastrointestinal bleeding
Interaction Deep Dive
Taking apixaban together with an oral glucocorticoid may raise the likelihood of bleeding1, such as gastrointestinal bleeding (GIB). A cohort study found that individuals who received non-vitamin K oral anticoagulants (NOACs) alongside oral glucocorticoids within the previous 60 days had a greater incidence of GIB than those who had not been given glucocorticoids; this elevated risk was seen with larger glucocorticoid doses and among patients with a greater tendency toward bleeding 2. When the two agents must be used together, careful monitoring is advised 21.
Why it happens (mechanism)
Precise mechanism unknown
How to manage this interaction
If both medicines are needed, your care team can manage this safely. Typically they will:
- Monitor you more closely for signs of bleeding, especially if your steroid dose is higher or you already have bleeding risk factors.
- Review whether the dexamethasone dose can be individualized to your needs.
What you can do:
- Keep taking both apixaban and dexamethasone as prescribed, do not stop on your own.
- Report right away: black or tarry stools, blood in stool, vomit resembling coffee grounds, unusual bruising, dizziness, or ongoing stomach pain.
- Ask your pharmacist whether stomach-protecting steps make sense for you.
Management is individual — confirm any change with your pharmacist or prescriber.

a) In a nested case-control study drawn from a large cohort of Danish adults with atrial fibrillation (N=98,376; median age 75 years; 44% female; 16% exposed to glucocorticoids; 35% receiving apixaban), taking non-vitamin K oral anticoagulants (NOACs) together with oral glucocorticoids was linked to a higher risk of gastrointestinal bleeding (GIB) than NOACs used by themselves. In patients prescribed oral glucocorticoids at an equipotent dose below 20 mg of daily predniSOLONE during the previous 60 days (n=727), GIB was seen in 25% compared with 16% in the unexposed control group (n=28,363) [HR, 1.54; 95% CI, 1.29 to 1.84]. Relative to no exposure, this risk rose further when an equipotent dose of 20 mg predniSOLONE or more daily was prescribed (n=536), with 32% of this group experiencing GIB [HR, 2.19; 95% CI, 1.81 to 2.65]. Most glucocorticoid prescriptions were for oral predniSOLONE (84.5%), and inflammatory lung disease was the most frequent indication (30.8%). Additional indications comprised rheumatic disease (8.4%) and cancer (8.1%); nevertheless, a non-specific or unknown indication for glucocorticoids was noted in 52.6% of the exposed group. Individuals in the exposure group had a documented prescription for any glucocorticoid within the 60 days before GIB, but detailed data on the length of glucocorticoid therapy and its timing relative to when GIB hospitalization occurred were not reported 2.
Common questions
Can I take Apixaban and Dexamethasone together?
