Blood Clots

LEO Pharma has been developing 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


Although blood clots can be difficult to detect, they are highly treatable. Common treatment is using heparins, a natural "anticoagulant" or clot-buster. Heparin-based products can be given to prevent blood clots in people at high risk, or to treat already-formed blood clots, such as DVT or PE. Successful treatment can help prevent their potentially disabling and life-threatening consequences.

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.
