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.
My doctor said that Eliquis does a better job of protecting from clots but has a higher risk of bleeding. The aspirin has a lower risk of bleeding but doesn't protect from clots as well. He said these are tiny percentages of a difference, though.
He wants to switch me to something lower dose since I have made it through 6 months. (When I was in the hospital, he said he generally prescribes something like Xarelto for 3-6 months and then switches patients to something less extreme if labs look good.) I know that some people stop taking blood thinners completely after they have made it 6 months or so, but my doctor does not recommend that for anyone. (It's an option, though; he just frowns upon it.)
After my second PE I was put on Xarelto. While on the initial 30mg daily dose, I haemorraged. Things got better when I switched to the lower, regime dose but I always had issues with heavy periods, gum bleeds and bruises (I do lots of sports).
Since heavier periods aggravated my iron-deficiency and gave me anemia, after one of my follow-ups I was switched to Eliquis (lower dosage, so 2.5mg twice daily). I switched directly from Xarelto, what I did was taking my last Xarelto dose (I usually took it at 8pm at night) and started with Eliquis the day after, still at night (so, I basically skipped the morning dose).
I have been on Eliquis since June 2016 and I think this medication is a lot better for me.
I still have a (less severe) iron deficiency, but now I take iron tablets chronically and it is taking care of that.
It looks like I will stay on it lifelong, if things keep on going well. My doctors (hematologist + pulmonologist) do not think aspirin is a suitable option for me.
Good luck!
I went for a 9-month follow-up a few weeks ago, and my hematologist wants to keep me on Eliquis for at least another 6 months. I think this may be protocol (at least in my area). When speaking with my cardiologist, he told me it is normal to go on something like Xarelto for 6 months and then something lower-dose like Eliquis for maybe a year. My d-dimer is looking great these days (<0.27).
