Question: do coumadin cause blood clots?
Answer: Yes. Medications that are commonly called blood thinners — such as aspirin, warfarin (Coumadin, Jantoven), dabigatran (Pradaxa), rivaroxaban (Xarelto), apixaban (Eliquis) and heparin — significantly decrease your risk of blood clotting, but will not decrease the risk to zero.
