What is idarucizumab?
Idarucizumab is a drug that reverses the effects of another medicine called dabigatran (Pradaxa). Dabigatran is used to prevent blood clots and strokes in people with certain heart disorders. Because the medicine keeps the blood from clotting, people taking dabigatran can bleed more easily.
Idarucizumab is used during a medical emergency to treat severe or uncontrolled bleeding that has been caused by taking dabigatran.
Idarucizumab is also used when an emergency surgery or other invasive medical procedure is needed in a person who takes dabigatran.
Idarucizumab may also be used for purposes not listed in this medication guide.

sudden numbness or weakness (especially on one side of the body);
problems with vision or speech;
chest pain, wheezing, coughing up blood; or
pain, swelling, warmth, or redness in one or both legs.
After you receive idarucizumab, tell your caregivers right away if you have:
any bleeding that will not stop;
lung problems--fever, chills, cough with yellow or green mucus, chest pain, feeling short of breath; or
low potassium--leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling, muscle weakness or limp feeling.
