Take the prevention pledge to prevent thrombosis.
Protect your health.

I am taking this prevention pledge to take charge of my health and help protect others by taking simple, life-saving steps to prevent blood clots:

  • I will learn to recognize the signs and symptoms of blood clots so I can act quickly and seek medical care when it matters most.

  • I will understand my personal risk factors—like cancer, heart disease, diabetes, or other health conditions—and discuss them openly with my healthcare provider to make informed decisions about prevention.

  • I will stay active and keep moving, especially during long periods of sitting, travel, or recovery—because even small steps help keep blood flowing.

  • I will follow my doctor’s advice carefully, taking prescribed medications exactly as directed and staying updated on the latest information about blood clot risks.

  • I will share what I learn with my family, friends, and community—because raising awareness can save lives.

Together, we can stop the silent threat of blood clots!

Pledge to prevent thrombosis. Potect Your health.
