Blood Clots

What Medications Affect the Clotting Process?

Some drugs stop platelets from signaling each other so they won't stick together.

Medicines called blood thinnersmake it hard for your body to make clotting factors, or they prevent proteins in the clot-forming process from working.

A clot-dissolving drug called tissue plasminogen activator (tPA) activates the protein that breaks down the fibrin strands. Sometimes doctors prescribe it as a treatment for heart attack or stroke.

In emergency cases involving patients using Pradaxa, the drug idarucizumab (Praxbind) can be used to help reverse Pradaxa's blood-thinning effects.

Which Medical Conditions Cause Blood-Clotting Problems?

You're more likely to get clots you don't need when you don't have the right balance between the kinds of proteins that cause and stop clotting in your blood.

People with hemophiliahave a problem with their genes. Their bodies don't make some clotting factors correctly, so their blood doesn't clot well and they can bleed a lot.

A relatively common condition called von Willebrand factor deficiency makes blood clots form slowly because your body doesn't have enough of a specific protein to trigger the clotting process. It's usually mild.
