Blood clots are dangerous. If they break away from the walls of your veins, they can circulate through your bloodstream and cause further complications. That's why doctors prescribe blood thinners to patients at risk of developing blood clots. The generic names of blood thinners are warfarin, rivaroxaban, dabigatran, apixaban and heparin. You can also find them sold under the brand names of blood thinners: Coumadin, Xarelto, Pradaxa, Eliquis and Jantoven.
How Blood Thinners Work
Blood thinners decrease the blood's ability to clot. This lowers the risk of developing a potentially fatal blood clot, but at the same time increases the risk of bleeding in some people. Most of the time this isn't a concern, but that doesn't mean you should ignore unusual bleeding (including heavier than normal menstrual bleeding) or bruising. You should also tell medical professionals about falls and bumps to the head. It's possible to have internal bleeding and not be aware of it. That's why you should know and be on the lookout for signs of severe bleeding—even when you can’t physically see it.
