Key takeaways
Enoxaparin (Lovenox) and aspirin are both used to prevent blood clots, but they work in different ways and are used for different purposes. Enoxaparin is a prescription blood thinner given by injection and is used to treat and prevent blood clots in people undergoing surgery or those with certain heart conditions. It works by blocking proteins that help form clots. Aspirin, on the other hand, is an over-the-counter nonsteroidal anti-inflammatory drug (NSAID) taken orally, which can help lower the risk of heart attack and stroke when taken at low doses (81 mg). It also helps reduce pain, fever, and inflammation. Enoxaparin is the preferred choice for pregnant women, except those with prosthetic heart valves, whereas aspirin should be used cautiously during pregnancy as it can cause harm to unborn babies. Both medications can increase the risk of bleeding.
