edoxaban vs rifampin
Side-by-side comparison of edoxaban and rifampin. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.
moderate Known Drug Interaction
( 7.1 ) Rifampin: Avoid concomitant use ( 7.2 ) 7.1 Anticoagulants, Antiplatelets, Thrombolytics, and SSRIs/SNRIs Co-administration of anticoagulants, antiplatelet drugs, thrombolytics and SSRIs or SNRIs may increase the risk of bleeding. 7.2 P-gp Inducers Avoid the concomitant use of SAVAYSA with rifampin [see Clinical Pharmacology (12.3) ] .
Recommendation: You should avoid taking these two medications at the same time.
Savaysa is a medicine that helps to prevent blood clots. It is used to lower the chance of stroke in people with an irregular heartbeat (atrial fibrillation) and to treat blood clots in the legs or lungs.
Rifampin is an antibiotic medicine. It fights bacteria in your body to treat infections.
Savaysa is used to lower the risk of stroke and blood clots in people with nonvalvular atrial fibrillation, a type of irregular heartbeat. It is also used to treat blood clots in the deep veins of your legs (DVT) or in your lungs (PE). You will likely need to take another medicine to prevent blood clots for 5 to 10 days before starting Savaysa for DVT or PE.
Rifampin treats tuberculosis (TB) and helps eliminate the bacteria that cause meningitis from your nose and throat. It is important to use rifampin only for infections that are proven or strongly suspected to be caused by bacteria. This helps to prevent bacteria from becoming resistant to the medicine.
Savaysa is a factor Xa inhibitor. This means it blocks a substance in your blood called factor Xa. By blocking factor Xa, Savaysa helps to prevent blood from clotting.
Rifampin works by stopping bacteria from growing and multiplying. It does this by blocking a key enzyme that the bacteria need to make proteins. This helps your body fight off the infection.

Savaysa may not work as well to prevent strokes if you have atrial fibrillation and your kidneys are working very well (CrCl > 95 mL/min). If you stop taking Savaysa too soon, you have a higher risk of blood clots or stroke. If you get medicine injected into your spine while taking Savaysa, it could cause bleeding around your spine, which can lead to paralysis.
Rifampin can cause liver problems. Tell your doctor right away if you have yellowing of the skin or eyes, dark urine, or stomach pain. Rifampin can also cause blood problems. Tell your doctor if you have unusual bleeding or bruising.
Tell your doctor if you are pregnant or plan to become pregnant. Savaysa may increase the risk of bleeding in the fetus. Do not breastfeed while taking Savaysa.
Tell your doctor if you are pregnant or plan to become pregnant. Rifampin can make birth control pills less effective, so use other forms of birth control. Talk to your doctor if you are breastfeeding.

How to Read This edoxaban vs rifampin Comparison
edoxaban is classified in the Direct Oral Anticoagulant (Factor Xa Inhibitor) drug class, while rifampin sits within the Rifamycin Antibiotic class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, edoxaban has 0 submissions while rifampin has 3,416. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to rifampin causes your body to clear the blood thinner too quickly, which could make the medicine fail to prevent blood clots.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
