Idarucizumab, sold under the brand name Praxbind, is a medication used to reverse the effects of dabigatran.[1] Specifically it is used if severe bleeding or urgent surgery is required.[1] It is given by injection into a vein.[3]

Common side effects include headache, nausea, and constipation.[1] Severe side effects may include blood clots and allergic reactions.[1] It is a monoclonal antibody that works by binding to and inactivating dabigatran.[1][2]

Idarucizumab was approved for medical use in the United States and Europe in 2015.[1][2] In the United Kingdom it costs the NHS about £2,400 for a dose as of 2021.[3] This amount in the United States costs about 4,500 USD.[4]

Medical uses

Dabigatran can be started again once 24 hours has passed from this medication being given.[3]


It is given as a dose of 5 gram.[1] Occasionally a second 5 gram dose may be used.[3]
