Summary
Mifepristone abortion causes uterine bleeding that can be heavy, and therapeutic low-molecular-weight heparin such as bemiparin may worsen it.
What this interaction means in plain words
Bemiparin and Mifepristone can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Additive pharmacodynamic effect: anticoagulation on top of expected uterine bleeding.
What to do
Avoid unless anticoagulation is essential. If needed, consider timing or dose adjustment with specialist input and monitor bleeding and hemoglobin.
