I take eliquis and have done so for a year-plus, against the risk of stroke following upon atrial fibrillation.My by-mail druggist has told me that my Rx will arrive three days later than I had anticipated, and unfortunately I had only a one-day extra supply of eliquis. I still have some leftover warfarin from before I shifted to Eliquis. I read that the interaction between eliquis and the warfarin is simply because of excessive thinning, but I have in mind for those two missing days (July 4 holiday complicates earlier delivery) for doing the eliquis while I still have it, then shifting to the warfarin, and shifting back when, after 2 days, my refill for eliquis arrives. Would I be wiser to buy some aspirin and use them ad interim instead? Thank you for your advice.
