What is the most important information I should know about coagulation factor Xa?

What is coagulation factor Xa?

Coagulation factor Xa is a protein that reverses the effects of certain anticoagulant medications that are used to treat or prevent blood clots. Reversing anticoagulant medicine is necessary if you have uncontrolled or life-threatening bleeding as a result of how that medicine works.

Coagulation factor Xa is used to treat uncontrolled bleeding in people who take the anticoagulants rivaroxaban (Xarelto) and apixaban (Eliquis).

Coagulation factor Xa was approved by the US Food and Drug Administration (FDA) on an "accelerated" basis. In clinical studies, healthy volunteers responded to this medicine, but further studies are needed.

Coagulation factor Xa may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before receiving coagulation factor Xa?

You should not be treated with coagulation factor Xa if you have had an allergic reaction to clotting factor medicine.

In an emergency, you may not be able to tell caregivers about your health conditions. Make sure any doctor caring for you afterward knows you received this medicine.

In an emergency, you may not be able to tell caregivers if you are pregnant or breast feeding. Make sure any doctor caring for your pregnancy or your baby knows you received this medicine.

How is coagulation factor Xa given?

Coagulation factor Xa is given as an infusion into a vein. A healthcare provider will give you this injection.

This medicine must be given slowly, and the infusion can take at least 2 hours to complete.

Once your bleeding has been controlled, you may need to begin using anticoagulant medication again to prevent future blood clots. Follow your doctor's instructions very carefully.

What happens if I miss a dose?

Because you will receive coagulation factor Xa in a clinical setting, you are not likely to miss a dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid after receiving coagulation factor Xa?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
