Injectable Anticoagulants
What are they and why do we need them?
Injectable anticoagulants can be used for many reasons. Outside the hospital, injectable anticoagulants may be used as a “bridge” for when you are starting warfarin or stopping warfarin for a short period of time. Warfarin commonly takes 5-7 days to take its full effect in your system and during that time we may need to use an injectable anticoagulant.
This table compares two common types of injectable anticoagulants and includes links to injection videos and the manufacturer’s website.
