How Enoxaparin works?

It helps reduce blood clots (known as deep vein thrombi (DVT)) from forming in your leg veins.

If blood clots have formed, it helps prevent them from getting bigger or breaking off and moving to the lungs (pulmonary emboli).

The body breaks down this medication in the liver and it is excreted by the kidneys.

Why is Enoxaparin considered for all patients admitted to hospital?

  2. You may have a condition/s which may put you at increased risk of developing a blood clot, for example mechanical valve, irregular heart rhythm, COVID-19 infection or cancer.
  3. You may have developed a blood clot.

On admission your doctor will assess you and advised you about commencement of Enoxaparin.

Side effects of Enoxaparin

Enoxaparin may have some side effects. The most common side effects are swelling, bruising and/or an occasional droplet of blood at the injection site after you have taken out the needle.
