Ive been taking Warafin for about 2 years now and cost-wise, its much more affordable than Elequis or Xarelto. As mentioned in another post, the down side is the frequent blood check. But i had the Watchman device implanted on October 14th . I go back for the TEE January 2nd, 2020. Hopefully things will be good and i'll be able to come off Warafin . I've been told if things are ok, i'll go on one baby asprin daily and one plavix, daily.
