Key takeaways
Enoxaparin (Lovenox) and heparin are both anticoagulants, or blood thinners, used to treat and prevent blood clots. They are similar in that they help prevent clots from getting bigger and reduce the risk of new clots forming. However, they differ in several ways. Enoxaparin is a low-molecular-weight heparin, typically given as an injection under the skin once or twice a day, and is FDA-approved for conditions like heart attacks. It is available in both brand and generic forms. Heparin, on the other hand, is given either through the veins or under the skin and requires regular blood tests to monitor its effects. It is often used in hospital settings and is not available in branded forms. Both medications can cause side effects like bleeding and low platelet counts, but enoxaparin is generally preferred for pregnant women. Additionally, enoxaparin (Lovenox) has a longer-lasting effect compared to heparin, which works quickly but stays in your system for a shorter time.
