I can tell you a little bit about aspirin thearpy. I cant say it works 100% but it has worked for me. The reason I chose not to do coumadin thearpy is because I am a police officer. I was afraid that since my job is physically a high risk I didnt want to die because I was bleeding internally. I take 2 aspirins a day which come out to 650mg. I make sure I elevate my legs when I go to sleep. It may not be every night but I do it at least a couple nights a week. Just to make sure my blood is at a right level I will go to my oncologist every 3 to 4 months to make sure my blood is a good consistency. If it is then I continue to take the aspirin every day. I know it may not give you all the information you wanted but hopefully it helped a little. I was diagnosed with Factor V Leiden when I was 19 and had knee surgery.

Aspirin therapy is of absolutely no benefit to someone with Factor V Leiden. Aspirin is effective in preventing arterial clots, but not venous clots. Your hematologist is an idiot and you are at risk of clotting again without warfarin therapy.

My son is 5 years old. He is taking aspirin and hematologist said is the best for him. They make him blood test and they said is ok for now but maybe in the future he need another medication
