This is when I have seen both given as well. Coumadin takes a while to become therapeautic. There are sometimes meds that interfere and take it longer to become therapeutic.
While the Coumadin is becoming therapeautic the Lovenox is given to prevent clot formation. When the Coumadin is able to handle this alone, the Lovenox should be discontinued.
