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.
What happens
Increased risk of gastrointestinal bleeding
Interaction Deep Dive
Concomitant use of edoxaban with an oral glucocorticoid may increase the risk of gastrointestinal bleeding (GIB). In a cohort study, patients prescribed non-vitamin K oral anticoagulants (NOACs) concomitantly with oral glucocorticoids in the preceding 60 days experienced a higher rate of GIB compared with those who were not prescribed glucocorticoids; increased risk was noted with higher dosages of glucocorticoids and in those with increased propensity for bleeding. If coadministration is necessary, close monitoring is recommended1.
Why it happens (mechanism)

a) Concomitant use of non-vitamin K oral anticoagulants (NOACs) and oral glucocorticoids was associated with an increased risk of gastrointestinal bleeding (GIB) when compared with NOACs alone in a nested case-control study from a large cohort of Danish adults with atrial fibrillation (N=98,376; median age 75 years; 44% female; 16% exposed to glucocorticoids). Two percent of the cohort were receiving edoxaban, with 36%, 35%, and 27% receiving rivaroxaban, apixaban, and dabigatran, respectively. Among those who were prescribed oral glucocorticoids at an equipotent dosage of less than 20 mg of daily predniSOLONE in the preceding 60 days (n=727), GIB occurred in 25% vs 16% in the unexposed control group (n=28,363) [HR, 1.54; 95% CI, 1.29 to 1.84]. In comparison to no exposure, this risk was further increased when an equipotent dosage of 20 mg predniSOLONE or more daily was prescribed (n=536), with 32% in this group experiencing GIB [HR, 2.19; 95% CI, 1.81 to 2.65]. The majority of glucocorticoid prescriptions were for oral predniSOLONE (84.5%), with inflammatory lung disease being the most common indication (30.8%). Other indications included rheumatic disease (8.4%) and cancer (8.1%); however, a non-specific or unknown indication for glucocorticoids was reported in 52.6% of the exposed group. Those in the exposure group had a recorded prescription for any glucocorticoid within 60 days preceding GIB, but detailed information related to duration of glucocorticoid treatment and timing of treatment relative to GIB hospitalization occurrence was not reported 1.
