What anticoagulants affect INR?
Direct oral anticoagulants (DOACs), particularly direct factor Xa inhibitors, have been associated with prolongation of the prothrombin time and the international normalized ratio (INR). Although DOACs do not require monitoring, elevations in the INR have been reported in in vitro and observational studies.
What can cause an elevated INR?
- Too much anticoagulant medicine, a type of blood thinner that helps prevent clots.
- Other medicines, such as aspirin, NSAIDs, and some antibiotics, when you also are using anticoagulants.

What is the safest blood thinner to take?
Safer Blood-Thinning Drugs to Prevent Stroke The newer medications are Pradaxa (dabigatran), Xarelto (rivaroxaban), Eliquis (apixaban), and most recently Savaysa (edoxaban) — which work by preventing pooled blood in the heart from clotting. Unlike warfarin, the newer drugs are safer and easier for patients to use.

What happens if you take Xarelto on an empty stomach?
