Lovenox Dosage
When beginning treatment with Lovenox, the dosage will depend on various factors, such as your weight, kidney function, and the reason you are using this drug. This medication is given as an injection just under the skin once or twice a day. Make sure to take Lovenox as prescribed. If you stop taking it too soon, you may be increasing your risk for serious problems.
The dose of Lovenox® (enoxaparin sodium) your healthcare provider recommends will vary, depending on a number of factors, including:
- The reason you are taking Lovenox
- Your weight
- Your kidney function
- Other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
