5.0/ 7 average rating with 343 reviewsforPlavix
Prevents blood clots.

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
  • Plavix (clopidogrel) can help lower your risk of getting a stroke or heart attack.
  • You only need to take it once a day.
  • A genetic test is available to determine whether Plavix (clopidogrel) will be an effective treatment option for you.
  • 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
  • Raises your risk of bleeding and bruising, which can be serious and life-threatening.
  • May not be safe to be taken with many other medicines or supplements.
  • If you've taken too much Plavix (clopidogrel) and you're bleeding, plasma transfusions are required to stop the bleeding.
  • 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.
