Yes, I was going to say that too. There are no antidotes for Xarelto or Pradaxa except a plasma transfusion. Xarelto has a half life of 5-12 hours, while Pradaxa is around 18. So you can see the complication if you would need emergency surgery for some reason. Coumadin is certainly tried and true and the cost difference is HUGE. The main problem with Coumadin is the dose levels have to be done carefully, and are greatly affected by age, diet, and what else you're taking besides the Coumadin. So the amount of the drug in your blood at any given time can be all over the place.
My sister is an insane runner in her early 50's. She does 7 to 9 miles daily. One morning she pulled up lame, and it got really bad. The next day she had to be carried into the hospital where a quick x-ray revealed the had a DVT in her calf. The physician prescribed Xarelto, not Coumadin. She was on it for several months and did well. No gastric issue at all. But she was restricted from absolutely anything that would put her in a situation where she could be injured. She's also jumps horses and has been known to take some rather severe tumbles. Even running was out while on Xarelto. So consider the impact your lifestyle may have if you begin Xarelto. There's another one out there now too; Eliquis. You should discuss the options with your physician to decide which one is best.
Dont rule out warfarin. It is a little more maintenance but there is an antidote for it iin case you have a bleeding incident. The antidotes for xarelto and pradaxa are still being developed. My 93 yr old father in law has been on warfarin for 20+ years now and doing ok with it.
