What is the difference between warfarin and lovenox (enoxaparin)?

Many: Warfarin is a vitamin k antagonist and is given in pill form and is much cheaper, requires constant checking levels in the blood ( pt-inr). Lovenox (enoxaparin) is a low molecular sintetic heparin, injectable once or twice a day subcutaneously, much more expensive buy does not requiere to check the levels in the blood tests. Warfarin has to be stopped 3 to 5 days before surgery, Lovenox (enoxaparin) only 36 hrs.

Different meds: They are different meds. Lovenox (enoxaparin) is low molecular weight Heparin it is a shot (injection) that is quite expansive, but doesn't require dietary changes or blood work for monitoring or has as many drug-drug interactions as warfarin (coumadin) that is cheaper oral medicine that requires extensive monitoring, can cause a lot of issues, but in some cases Coumadin will be indicated and Lovenox (enoxaparin) will not.

Anticoagulants: Warfarin is a blood thinner in the form of a pill & usually takes 3 to 4 days to work wheras Lovenox (enoxaparin) is an injectable drug & it works right away.

See below: Both are blood thinners that act on different parts of the coagulation (clotting) pathway in our system, warfarin is oral and needs regular blood test to check if it is in a good level, avoid eating vitamin k rich foods like dark greens while on this med. Lovenox (enoxaparin) is injectable, dosing computed thru weight.
