Do you have to take lovenox (enoxaparin) before warfarin?

Do you have to take lovenox (enoxaparin) before warfarin?

Usually: Unless you were on Heparin or one of the other lmwh's (like arixtra), yes it is recommended to be anticoagulated when starting warfarin. This is because there is a brief increase in coagulation tendencies by release of the vit-k dependent clotting factors w/start of warfarin. Once depleted (few days), the Lovenox (enoxaparin) can be stopped. ...Read more

Pulmonary embolism: Can be fatal if they are big enough. When your doctor investigated its source, he probably could not find it, if he did not recommend any other treatment. You should be on anticoagulants to minimize recurrence. And you should stop taking any meds that might predispose you, such as birth control pills, and stop smoking if you do smoke. Talk to your doctor on how to minimize your future risk. ...Read more

Temp off Warfarin and on Lovenox (enoxaparin) injections twice a day. Drank on warfarin without issue, can I still have a few beers on the lovenox (enoxaparin)?

Temp off Warfarin and on Lovenox (enoxaparin) injections twice a day.  Drank on warfarin without issue, can I still have a few beers on the lovenox (enoxaparin)?

No: and I would ask why you aren't directing this question at the prescribers? I am sure if you asked your doctor whether it's ok to drink on Warfarin, s/he would tell you NO in no uncertain terms. Even moderate drinking impairs the metabolism of warfarin, often making you require higher doses, which is if you then lower your drinking may cause a high INR and bleeding risk. It is DANGEROUS. Stop. ...Read more

My boyfriend has 2 clots in his lungs and is currently on warfarin/lovenox but INR is 1.4. What does this mean?

INR too low: Inr is a measure of relative blood "thinning", from warfarin. The Lovenox (enoxaparin) will keep his blood thin until the warfarin/inr level reaches a therapeutic levels between 2 and 3. Once the inr level is appropriate, the Lovenox (enoxaparin) can then be stopped. ...Read more

Why does my doctor have me come off warfarin 5 days before a surgical procedure and take lovenox (enoxaparin) instead?

Because...: Your doctor does not want you to bleed during the surgery and in the same time your doctor does not want you to develop another kind of blood clots while you are not taking your warfarin. That is why your doctor wants you to stop the warfarin and bridged you on the Lovenox (enoxaparin) while you are off the warfarin. Please discuss with your doctor for other question. ...Read more

My mom is on coumadin (warfarin) and lovenox but her INR is only 1.3. She recently had a stroke nd dvt. Isnt she at  risk of another stroke with low INR?

No: Lovenox provides anti coagulation while Coumadin (warfarin), (warfarin) which takes a long time to have a complete effect, as measured by INR, starts to work. She's not at increased risk. Make sure to look at the dietary restrictions and drug interactions with Coumadin (warfarin) which might be the reason the INR is still low. ...Read more

DVT in left calf diagnosed a week ago.  On Lovenox (2x day) and 5mg Coumadin (warfarin).  Experiencing left sided tingling in leg, arm and head (slight headache too).  Is this a side affect from meds?

Blood thinners: Headaches are not a usual side effect of Coumadin (warfarin). If this is a new headache or a variation of the usual headaches then seek medical attention to make sure there is no bleeding in the brain. The risk of bleeding is low (1.5%) but headaches are a concern that needs medical attention. ...Read more

What is the difference between Coumadin (warfarin) and levinox?

A shot and not: As dr. Milstone said, Coumadin (warfarin) in a pill and Lovenox is a shot. The amount of Coumadin (warfarin) you take has to be checked with blood tests on a regular basis. Lovenox does not but Lovenox can cause a very serious side effect involving your platelets that Coumadin (warfarin) doesn't. Lovenox is expenisve, Coumadin (warfarin) is much cheaper. Both can cause bleeding. If that happens, the effects of Lovenox reverse faster. ...Read more
