We've been working to improve patients' lives with thrombosis products for more than 50 years

Today, we continue to be passionate about understanding the challenges that patients and healthcare professionals encounter.

LEO Pharma has developed products for people with blood clot disorders for more than 50 years. We listen to how people experience living with these life-critical conditions – to develop treatments to make their lives as comfortable as possible.




Potentially dangerous blood clots can develop in the deep veins of our legs for many reasons, including genetics and as a result of surgery. There are two types of blood clots:


  • Deep vein thrombosis (DVT), which occurs in the deep veins
  • Pulmonary embolism (PE), which occurs when a blood clot travels to the lungs


As part of our commitment to this critical area, we partner with the Canadian Cancer Survivor Network, as part of World Thrombosis Day. We are also a proud sponsor of Thrombosis Canada.
