Precautions
One of the most popular treatments is a prescription blood thinner called Lovenox, also known as enoxaparin. If you are at high risk for blood clots in pregnancy, or if you are currently experiencing a blood clot during pregnancy, you are probably wondering if Lovenox is a good choice for you.
Is Lovenox (enoxaparin) safe during pregnancy?
Enoxaparin has been increasingly used over the past 20 years in pregnant women at risk of thrombosis and pregnancy complications. The main indications are prophylaxis of venous thromboembolism and prevention of pregnancy loss in thrombophilic women.
What is enoxaparin used to treat?
The main indications are prophylaxis of venous thromboembolism and prevention of pregnancy loss … Enoxaparin use in pregnancy: state of the art Womens Health (Lond). 2007 Jan;3(1):9-14.doi: 10.2217/17455057.3.1.9. Author Benjamin Brenner 1 Affiliation
What are the indications for enoxaparin in pregnancy?
Conclusion: Literature on the efficacy and safety of enoxaparin for thromboembolism and thromboprophylaxis remains scanty, and therefore efficacy was not assessed; in terms of safety, when including other indications for enoxaparin in pregnancy, we found that enoxaparin was associated with significantly lower complications than aspirin.
Is enoxaparin effective and safe for thromboembolism and thromboprophylaxis?
Can you use enoxaparin during pregnancy?
Enoxaparin does not cross the placenta and is safe for the fetus. Maternal side effects are uncommon and include mild localized allergic reactions in 2% and increased bleeding in 2%, which is dose dependent.
When should enoxaparin be stopped during pregnancy?
Women should be advised to stop their LMWH when contractions begin. For a planned delivery, most guidelines recommend stopping enoxaparin within 24 hours, and this is especially important if an epidural is desired.
Where do you inject enoxaparin when pregnant?
The best places for you to inject into are: • The U-shape area around your belly button. It is safe to inject LMWH into the abdomen while pregnant. The upper outer side of the thigh. The upper outer part of the buttock.
What blood thinners are safe during pregnancy?
Standard or “unfractionated” heparin and low-molecular-weight heparin (LMWH) are safe in pregnancy because they do not cross the placenta and, therefore, do not enter the blood stream of unborn babies.
Is enoxaparin high risk?
Extra care is needed because enoxaparin is a high-alert medicine. High-alert medicines have been proven to be safe and effective. But these medicines can cause serious injury if a mistake happens while taking them. This means that it is very important for you to know about this medicine and take it exactly as directed.

During the study, 30.4% of women enrolled in the enoxaparin group vs 23.7% in the placebo group had a subsequent miscarriage (relative risk, 1.28; 95% CI, 0.85-1.93). Most of the losses (84.3%) occurred before 10 weeks' gestation.
What time should enoxaparin be given?
Timing of dose Enoxaparin should be administered at approximately the same time each day. 6pm has been traditional, but if anti-factor Xa levels are required (very infrequently required and normally only on the advice of a specialist), 8am is preferred as blood samples are required 4 hours post dose.

Is enoxaparin safe for pregnancy?

What is enoxaparin used for?
It has approval for the following clinical conditions - acute coronary syndromes, deep venous thrombosis (DVT) treatment and prophylaxis, treatment for pulmonary embolism (PE), venous thromboembolism (VTE) treatment and prophylaxis in a variety of scenarios, percutaneous coronary intervention (PCI), and periprocedural anticoagulation, among others. This activity will highlight the mechanism of action, adverse event profile, pharmacology, monitoring, and relevant interactions of enoxaparin, pertinent for members of the interprofessional team in the treatment of patients with conditions where this agent is indicated.
What is the management of enoxaparin?
The management of bleeding complica tions of enoxaparin is challenging, and it requires the inclusion of interprofessional health care team members such as the physician, nurses, laboratory technician, and the pharmacist. The management should not be delayed, and intervention should take place as soon as possible. A blood bank should be contacted for possible need of an urgent transfusion. As discussed above, protamine sulfate is the drug of choice in this situation. A conservative approach is necessary for the consideration of acute bleeding. Anticoagulation should be stopped with the reversal of anticoagulation. Fluid resuscitation is also important if the patient is hemodynamically unstable.
What is the most common complication of enoxaparin?
As with most anticoagulants, bleeding is the most major complication with low molecular weight heparin-like enoxaparin. The incidence rate is reported to be less than 3%. Given the subcutaneous form of administration of LMWH, there is a high risk of minor bruising at the injection site. The subcutaneous injection has a bioavailability of around 100%. In the event of significant bleeding, protamine sulfate can be used to reverse the anticoagulant effects of LMWH partially. Protamine neutralizes about 60% of LMWH anticoagulant activity. For LMWH administered within the previous 8 hours, the recommended dose is 1mg protamine sulfate per 1mg of enoxaparin or 100 anti-factor-Xa units of dalteparin. [7]
What is the lowest molecular weight heparin?
There are two low molecular heparins available in the market: dalteparin and enoxaparin. Enoxaparin is low molecular weight heparin (LMWH) and was first approved for medical use in 1993 and is derived from heparin. It has approval for the following clinical conditions[1][2][3]:

Enoxaparin dose requires adjustment with a creatinine clearance of less than 30 mL/minute. [8]
How much enoxaparin should I take?
One mg of enoxaparin is equal to 100 units of anti-Xa activity. The usual dose is 1 milligram/kilogram every 12 hours. However, dosing can be variable depending on the clinical situation. For example, in acute coronary syndrome, 1 milligram/kg every 12 hours is indicated if the patient is less than 75 years of age. But 0.75 milligrams/kg every 12 hr is the dose if the patient is 75 years of age or older.
What is the molecular weight of enoxaparin?
Enoxaparin is a type of low molecular weight heparin (LMWHs) with a mean molecular weight of 4000 to 5000. It has an immediate onset of action when given in the intravenous form. It binds to and potentiates antithrombin III, a serine protease inhibitor, to form a complex that irreversibly inactivates factor Xa.[4] Enoxaparin has less activity against factor IIa (thrombin) compared to unfractionated heparin.
What Is Lovenox?
The ability of our blood to clot is important and necessary (for example, after you get a cut or injury, your blood clots so that you don’t continue bleeding profusely). However, if your blood clots too much, blood clots can form in the legs and other extremities and make their way to the lungs, causing a condition called pulmonary embolism (PE), which can be life-threatening if not treated promptly.

What happens if you have too much blood clots?
However, if your blood clots too much, blood clots can form in the legs and other extremities and make their way to the lungs, causing a condition called pulmonary embolism (PE), which can be life-threatening if not treated promptly.
Why do pregnant women have more clots?
Pregnant people are more prone to blood clots during pregnancy because a pregnant person’s blood naturally clots more easily to prevent blood loss during and after giving birth. Additionally, blood may not flow as easily to the legs during pregnancy as a result of the growing fetus putting pressure on pelvic blood vessels. 4.
