The short answer
The effect of ginger root powder on apixaban-related bleeding is uncertain. A severe case involving another anticoagulant and a ginger/cinnamon drink raises caution, but it does not prove this exact combination is harmful. Check the preparation and dose with your pharmacist; no protective spacing interval is established.
What this answer covers
Oral Zingiber Officinale (Ginger) Root Powder with adult oral apixaban. Powder, extracts, food portions and the reported mixed ginger/cinnamon decoction are not interchangeable.
- Supplement or preparation
- Ginger root powder
- Medication ingredient
- apixaban
What does the bleeding report tell us?
An 80-year-old man who had taken dabigatran for four years developed fatal gastrointestinal bleeding after three days of a boiled ginger/cinnamon mixture. The drink was 200 mL twice daily, but the amounts of each herb were not established. Because two herbs were combined, the report cannot isolate ginger or define a safe powder dose.
Does ginger increase the medicine’s blood level?
The reported patient took dabigatran, not apixaban. Transferring the outcome to apixaban would require an additional medication bridge that the case does not supply. A small study in 12 healthy men found no significant warfarin pharmacokinetic or clotting effect from its tested ginger preparation, which also does not settle apixaban co-use.
Which ginger product is being considered?
This page concerns a root-powder entry, so evidence from a tea or concentrated extract must be kept separate. Record the dose, formulation and any other herbs. Ordinary food seasoning is a different exposure from repeated concentrated supplements or a mixed medicinal drink.
What should I do before using it?
Apixaban acts directly on clotting factor Xa. Continue apixaban as prescribed and review the supplement with the treating team, including other medicines that increase bleeding risk. There is no tested time gap that neutralizes the uncertainty. Report unusual bleeding promptly and obtain urgent help for heavy bleeding, vomiting blood or black stools.
Evidence and practical considerations
Side effects & toxicity

- Exact scope
- Oral Zingiber Officinale (Ginger) Root Powder with adult oral apixaban. Powder, extracts, food portions and the reported mixed ginger/cinnamon decoction are not interchangeable. with adult oral apixaban tablets
- Medication form and route
- adult oral apixaban tablets
- Timing or duration
- Concurrent oral use. Source-specific durations are recorded in the evidence entries; no unstudied duration threshold or separation schedule is inferred.
What remains uncertain
- Mixed ginger/cinnamon case does not isolate ginger root powder, measure drug exposure or prove the proposed P-gp mechanism. Warfarin study is indirect; apixaban transfer adds another untested bridge.
Factors that may matter: Exact supplement preparation, dose and additional ingredients; Kidney function, age, bleeding history and other antiplatelet or anticoagulant medicines; Current medication formulation and recent supplement start or stop.

Source 1: current U.S. regulatory prescribing information
dailymed.nlm.nih.gov · Source check Sep 10, 2026
Population: People receiving oral apixaban for approved indications.
The label warns of serious bleeding and increased clot risk after premature discontinuation. It explicitly advises avoiding St. John’s wort because combined CYP3A4/P-gp induction reduces apixaban exposure.
How this applies: Establishes the exact medicine’s mechanism, baseline bleeding precautions and formulation/transport limitations; it does not establish this supplement-specific interaction. Exact scope: Oral Zingiber Officinale (Ginger) Root Powder with adult oral apixaban. Powder, extracts, food portions and the reported mixed ginger/cinnamon decoction are not interchangeable.
General antiplatelet-drug precautions do not establish the effect size or causality of each botanical. No herb-specific hourly separation schedule is supplied.
Source 2: peer-reviewed original research
pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026
Population: 12 healthy men in a randomized open-label crossover study.
Neither tested herb significantly changed warfarin clearance, INR response or platelet aggregation.
How this applies: Applied only as indirect context; the study or guidance did not establish an interaction with this exact direct oral anticoagulant. It is interpreted only alongside the current apixaban label; any source using warfarin or no anticoagulant is indirect for this pair. Exact scope: Oral Zingiber Officinale (Ginger) Root Powder with adult oral apixaban. Powder, extracts, food portions and the reported mixed ginger/cinnamon decoction are not interchangeable.
Healthy volunteers, single warfarin exposure and short follow-up; precise product strengths are not provided in the retrieved abstract. Does not establish safety during chronic anticoagulation or for every root powder or extract.
Source 3: original human case report
europepmc.org · Source check Sep 10, 2026
Population: 80-year-old man taking dabigatran 110 mg twice daily for four years; reported eGFR 90 mL/min/1.73 m2.
Fatal diffuse upper gastrointestinal bleeding occurred despite transfusion and idarucizumab.
How this applies: Different anticoagulant and mixed ginger/cinnamon drink; not direct evidence for apixaban with this named preparation. Exact scope: Oral Zingiber Officinale (Ginger) Root Powder with adult oral apixaban. Powder, extracts, food portions and the reported mixed ginger/cinnamon decoction are not interchangeable.
Two herbs taken together, no isolated ginger-root-powder exposure, no dabigatran concentration measurement and no rechallenge. The authors’ P-gp explanation is a hypothesis; the case does not establish increased prodrug absorption.
