Drug
Emicizumab-Kxwh
Pronounced
"EM-i-SIZ-ue-mab"
Uses
This medication is used by people with a certain inherited bleeding problem (hemophilia A) to help prevent or lessen how often you have bleeding problems. Emicizumab belongs to a class of medications known as monoclonal antibodies. It works by helping your blood to clot normally, which helps prevent bleeding due to hemophilia A. Preventing bleeding can lessen symptoms such as painful swellings, joint pain, pain with movement, and difficulty walking far.
Warning
This medication has rarely caused serious blood clots (including thrombotic microangiopathy) when used along with another product used to treat or prevent bleeding (activated prothrombin complex concentrate-aPCC). The risk is higher when aPCC has been used for 24 hours or longer and the dose has reached a certain amount. This interaction with aPCC may last up to 6 months after stopping emicizumab. Get medical help right away if you develop symptoms of serious blood clots, such as unusual decrease in the amount of urine, swelling ankles/feet, shortness of breath/rapid breathing, chest/jaw/left arm pain, unusual sweating, confusion, sudden dizziness/fainting, pain/swelling/warmth in the groin/calf, sudden/severe headaches, trouble speaking, weakness on one side of the body, sudden vision changes.
