The PT/ INR is prolonged by the new direct oral anticoagulants rivaroxaban (Xarelto) and apixaban (Eliquis), and the PTT is prolonged by the direct thrombin inhibitor dabigatran (Pradaxa). Neither test is prolonged by the antiplatelet drugs
Does Plavix affect INR?
Although the administration of clopidogrel 75 mg per day did not modify the pharmacokinetics of S-warfarin (a CYP2C9 substrate) or INR in patients receiving long-term warfarin therapy, coadministration of Plavix with warfarin increases the risk of bleeding because of independent effects on hemostasis .
Do antiplatelet drugs affect INR?
Antiplatelet drugs which inhibit platelet function impose additional risks for haemorrhage by affecting primary haemostasis and further inhibition of thrombus formation. Some antiplatelet drugs may also alter warfarin metabolism and lead to an unstable INR.
Does Plavix require INR monitoring?
Clopidogrel doesn’t require regular blood test monitoring , but it affects platelet function and bleeding times for up to 7–10 days. You may need to avoid elective dental work and elective operations while taking aspirin or clopidogrel due to risks of bleeding.
Does clopidogrel change INR?
Mean INR remained extremely stable in the clopidogrel group, the maximum percentage change from baseline being 0.6% at Day 6 . Plasma levels of R- and S-warfarin also remained very stable in those receiving clopidogrel.
Can you drink coffee with Plavix?
These medications are used to slow blood clotting and include aspirin, clopidogrel (Plavix), ibuprofen (Advil, Motrin, and others), naproxen (Anaprox, Naprosyn, and others), enoxaparin (Lovenox), and more.

What is the safest blood thinning medication?
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.
Can I take aspirin instead of blood thinners?
In general, aspirin is considered to be inferior to other blood thinners for reducing stroke risk in people with nonvalvular AFib and a CHA 2 DS 2 –VASc score of 2 or higher. When it comes to bleeding risk, aspirin is also not necessarily safer than some other blood thinners.
What is the difference between anticoagulants and blood thinners?
Anticoagulants, more commonly referred to as “blood thinners,” work by inhibiting the clotting factors . Antiplatelets work by inhibiting the enzymes that cause the platelets to clump together.
