Medication Guide

Read this Medication Guide before you start treatment and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment.

Important information

Bevyxxa can cause serious side effects, including:

  • Bleeding problems. Bevyxxa reduces blood clotting and can increase the risk of bleeding, which can be serious and may lead to death. The risk of bleeding is higher in people who have severe kidney problems (severe renal impairment).
    You may have a higher risk of bleeding if you take Bevyxxa and take other medicines that increase your risk of bleeding, including:
    • aspirin or aspirin containing products
    • long-term (chronic) use of non-steroidal anti-inflammatory drugs (NSAIDs)
    • warfarin sodium (Coumadin®, Jantoven®)
    • any medicine that contains heparin
    • selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs)
    • other medicines to prevent or treat blood clots
    • P-glycoprotein (P-gp) inhibitors
    Tell your healthcare provider if you take any of these medicines. Ask your healthcare provider or pharmacist if you are not sure if your medicine is one listed above.

    While taking Bevyxxa:
    • you may bruise more easily
    • it may take longer than usual for any bleeding to stop
    Call your healthcare provider or get medical help right away if you have any of these signs or symptoms of bleeding when taking Bevyxxa:
    • unexpected bleeding, or bleeding that lasts a long time such as:
      • unusual bleeding from the gums
      • nosebleeds that happen often
      • menstrual bleeding or vaginal bleeding that is heavier than normal
    • bleeding that is severe or you cannot control
    • red, pink, or brown urine
    • red or black stools (looks like tar)
    • cough up blood or blood clots
    • vomit blood or your vomit looks like coffee grounds
    • unexpected pain, swelling, or joint pain
    • headaches, feeling dizzy or weak
  • Spinal or epidural blood clots (hematoma). People who take a blood thinner medicine (anticoagulant) like Bevyxxa, and have medicine injected into their spinal and epidural area, or have a spinal puncture have a risk of forming a blood clot that can cause long-term or permanent loss of the ability to move (paralysis). Your risk of developing a spinal or epidural blood clot is higher if:
    • a thin tube called an epidural catheter is placed in your back to give you certain medicine
    • you take NSAIDs or a medicine to prevent blood from clotting
    • you have a history of difficult or repeated epidural or spinal punctures
    • you have a history of problems with your spine or have had surgery on your spine
    If you take Bevyxxa and receive spinal anesthesia or have a spinal puncture, your healthcare provider should watch you closely for symptoms of spinal or epidural blood clots. Tell your healthcare provider right away if you have back pain, tingling, numbness (especially in your legs and feet), muscle weakness, or loss of control of the bowels or bladder (incontinence).

What is Bevyxxa?

Bevyxxa is a prescription medicine used to help prevent blood clots in adults who are hospitalized for an acute illness, and are at risk of getting blood clots because of the loss of or decreased ability to move around (mobility) and other risks for getting blood clots.
