Our bottom line

Lovenox (Enoxaparin) is a good anticoagulant that reduces the risk of death or bleeding, and blood clots are less likely to happen. However, it is only available as an injection which isn't great if you're afraid of needles.

Upsides

  • In a study that compared Lovenox (Enoxaparin) to other medications used to stop blood clots, there was a lower risk of clots coming back, with similar rates of major bleeding and mortality.
  • You don't need to go in for lab tests to check whether it's working, unlike other medications like warfarin that require regular blood draws.
  • Available in generic so it can be cheaper than other "blood thinners".
  • Good option if you're pregnant or have cancer.

Downsides

  • It is only available as an injection, so it's not great if you're afraid of needles.
  • While surprise bleeding episodes can be treated while taking Lovenox (Enoxaparin), they won't completely work.
  • It doesn't work as well as other medications for "thinning the blood" if you are overweight, underweight, or if you have kidney disease.
