The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.
For people who take Savaysa for nonvalvular atrial fibrillation:
Your healthcare provider 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 your healthcare provider. Stopping Savaysa can increase your risk of having a stroke.
For all people who take Savaysa:
People who take a blood thinner medicine 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 ability to move. 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 nonsteroidal anti-inflammatory drugs (NSAIDs) (such as ibuprofen or naproxen) or a medicine to prevent blood from clotting, you have a history of difficult or repeated epidural or spinal punctures, or 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 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, loss of control of the bowels or bladder (incontinence).
Common side effects may include: bleeding, anemia (low red blood cell counts).
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 use of NSAIDs, blood thinner medicines (such as warfarin), any medicine that contains heparin, selective serotonin reuptake inhibitors (SSRIs) (such as fluoxetine and sertraline) or serotonin norepinephrine reuptake inhibitors (SNRIs) (such as duloxetine or venlafaxine), or other medicines to prevent or treat blood clots.
