Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
First thing would be to give your pharmacist a call and ask if there are known interactions. You might also consult your doc. Then, if you decide to try it, you might keep an eye on your INR for a while, just to see. Some folks react differently to these things, so maybe you'll have an interaction when someone else might not.
Pays to be cautious, but it also pays to know what you can use without worry.
I would check with your pharmacist or doctor.
