What is Savaysa?

Savaysa is a prescription medicine used to:

  • reduce the risk of stroke and blood clots in people who have atrial fibrillation not caused by a heart valve problem.
  • treat blood clots in the veins of your legs (deep vein thrombosis) or lungs (pulmonary embolism), after you have been treated with an injectable blood thinner medicine for 5 to 10 days.

It is not known if Savaysa is safe and effective in children.

What is the most important information I should know about Savaysa?

  • For people who take Savaysa for nonvalvular atrial fibrillation (a type of irregular heartbeat):
    People with nonvalvular atrial fibrillation are at an increased risk of forming a blood clot in the heart, which can travel to the brain, causing a stroke, or to other parts of the body. Savaysa reduces your risk of having a stroke by helping to prevent clots from forming.
    • Your doctor should check your kidney function before you start taking Savaysa. People whose kidneys work really well should not receive Savaysa because it may not work well to prevent stroke.
    • Do not stop taking Savaysa without first talking to the doctor who prescribed it for you. Stopping Savaysa increases your risk of having a stroke.
  • Savaysa can cause bleeding which can be serious, and sometimes lead to death. This is because Savaysa is a blood thinner medicine that reduces blood clotting. During treatment with Savaysa, you may bleed more easily, bleed longer, or bruise more easily. Call your doctor or get medical help right away if you experience bleeding that is severe (for example, coughing up or vomiting blood) or bleeding that cannot be controlled.
    You may have a higher risk of bleeding if you take Savaysa 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)
    • long-term (chronic) use of blood thinner medicines, such as:
      • 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
      Tell your doctor if you take any of these medicines. Ask your doctor or pharmacist if you are not sure if your medicine is one listed above.
  • Spinal or epidural blood clots (hematoma). People who take a blood thinner medicine (anticoagulant) like Savaysa, 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 Savaysa and receive spinal anesthesia or have a spinal puncture, your doctor should watch you closely for symptoms of spinal or epidural blood clots. Tell your doctor right away if you have back pain, tingling, numbness (especially in your legs and feet), muscle weakness, loss of control of the bowels or bladder (incontinence).
  • Savaysa is not for people with mechanical heart valves or people who have moderate to severe narrowing (stenosis) of their mitral valve.
  • Savaysa is not for use in people with antiphospholipid syndrome (APS), especially with positive triple antibody testing, who have a history of blood clots.

See "What are the possible side effects of Savaysa?" for more information about side effects.

Who should not take Savaysa?

Do not take Savaysa if you currently have certain types of abnormal bleeding.

What should I tell my healthcare provider before taking Savaysa?

Before taking Savaysa, tell your doctor about all of your medical conditions, including if you:

  • have liver or kidney problems
  • have antiphospholipid syndrome
  • have ever had bleeding problems
  • have a mechanical heart valve
  • have cancer of the stomach or intestine (gastrointestinal cancer)
  • are pregnant or plan to become pregnant. It is not known if Savaysa will harm your unborn baby. Tell your doctor right away if you become pregnant during treatment with Savaysa.
  • are breastfeeding or plan to breastfeed. It is not known if Savaysa passes into your breast milk. Do not breastfeed during treatment with Savaysa.

Tell all of your doctors and dentists that you are taking Savaysa. They should talk to the doctor who prescribed Savaysa for you, before you have any surgery, medical or dental procedure.
Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Some of your other medicines may affect the way Savaysa works. Certain medicines may increase your risk of bleeding or stroke when taken with Savaysa. See "What is the most important information I should know about Savaysa?"
Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

How should I take Savaysa?

  • Take Savaysa exactly as prescribed by your doctor.
  • Your doctor will decide how long you should take Savaysa. Do not change your dose or stop taking Savaysa unless your doctor tells you to. If you are taking Savaysa for nonvalvular atrial fibrillation, stopping Savaysa may increase your risk of having a stroke.
  • Take Savaysa with or without food.
  • If you have difficulty swallowing the tablet whole, talk to your doctor about other ways to take Savaysa.
  • If you miss a dose of Savaysa, take it as soon as you remember on the same day. Take your next dose at your usual time the next day. Do not take more than one dose of Savaysa at the same time to make up for a missed dose.
  • Do not run out of Savaysa. Refill your prescription before you run out. If you take too much Savaysa, go to the nearest hospital emergency room or call your doctor right away.
  • Call your doctor right away if you fall or injure yourself, especially if you hit your head. Your doctor may need to check you.
