Estrogen-Based Contraceptives and Lowering VTE Risk

The links between contraceptives and blood clots:

• Estrogen-based contraceptives can increase the risks for a life-threatening blood clot.
• Risks are present whether the estrogen is delivered into the blood stream with pills, a patch, an injection, or a vaginal ring contraceptive. The risk is highest when first starting these prescriptions.

Why does estrogen-based contraceptive use increase the risk of blood clots?

• Hormonal changes can cause blood cells to bind together more readily.
• Taking estrogen contraceptives can increase risks if you have other risk factors such as
  • Inherited blood-clotting disorders
  • Family history of blood clots
  • Surgery
  • Obesity
  • Prolonged travel

How can I reduce risk of an estrogen/contraceptive-related blood clot?

• Maintain a healthy weight.

  Keep your weight at a healthy level with diet and exercise.

• Drink water.

  Stay hydrated, especially during long-travel.

• Consider compression.

  Graduated compression stockings can be worn if advised by your healthcare provider.

• Know the symptoms.

  Learn to recognize the symptoms of a dangerous blood clot and speak up if you notice anything that concerns you.
