Edoxaban
Edoxaban tosylate · Say it: ed-OX-ah-ban
A once-daily blood thinner tablet used to lower the risk of stroke in people with an irregular heartbeat called nonvalvular atrial fibrillation, and to treat certain blood clots in the legs or lungs.
Brand names: Savaysa
⬛ Boxed warning (the FDA's strongest warning)
The boxed warning has three parts. (A) Reduced effectiveness in nonvalvular atrial fibrillation patients with creatinine clearance (CrCL) above 95 mL/min: Savaysa should not be used in these patients. In a clinical study, these patients had more ischemic strokes on Savaysa 60 mg than on warfarin, so another anticoagulant should be used. (B) Stopping early increases the risk of ischemic events: stopping any oral anticoagulant without adequate alternative anticoagulation raises the risk of clots and stroke. If Savaysa is stopped for a reason other than pathological bleeding or completing a course of therapy, the label says to consider coverage with another anticoagulant. (C) Spinal or epidural hematoma: people receiving spinal or epidural anesthesia, or having a spinal puncture, may develop a blood clot in the spine. This can cause long-term or permanent paralysis. The label says to consider these risks when scheduling spinal procedures.
Used for
To reduce the risk of stroke and systemic embolism (blood clots that travel to other parts of the body) in people with nonvalvular atrial fibrillation (AFib), a type of irregular heartbeat not caused by a heart valve problem.
Comes as
60 mg yellow, round, film-coated tablets (marked DSC L60); 30 mg pink, round, film-coated tablets (marked DSC L30)
Common side effects
For atrial fibrillation: bleeding and anemia (low red blood cell count) were the most common side effects, occurring in 5% or more of patients., For DVT and PE: bleeding, rash, abnormal liver function tests, and anemia were the most common side effects, occurring in 1% or more of patients., The label also warns that bleeding is the most common reason people stopped treatment in the atrial fibrillation study.

Get medical help right away if
- Get medical help right away if you have bleeding that is severe, such as coughing up or vomiting blood, or bleeding that cannot be controlled.
- Tell your healthcare provider right away if you notice bleeding that is unusual or that you cannot explain, or signs of blood loss.

🛑 Who should not take Edoxaban, and who should be careful
The label says not to take it if
- You currently have active pathological (abnormal) bleeding. The label says this is a contraindication.
- For atrial fibrillation: your creatinine clearance (CrCL) is above 95 mL/min. The label says Savaysa should not be used in this case.
- You have a mechanical heart valve. The label says use is not recommended.
- You have moderate to severe narrowing of the mitral valve (mitral stenosis). The label says use is not recommended.
- You have triple-positive antiphospholipid syndrome. The label says use is not recommended.
Tell your doctor before taking it if
- Your healthcare provider should check your kidney function before you start taking Savaysa.
- Tell your provider about all medical conditions, including liver or kidney problems, past bleeding problems, mechanical heart valves, antiphospholipid syndrome, and stomach or intestinal cancer.
- Tell your provider if you are pregnant, plan to become pregnant, or are breastfeeding.
- Tell all healthcare providers and dentists that you take Savaysa before any surgery, medical, or dental procedure.
- Tell your provider about all medicines you take, including over-the-counter medicines, vitamins, and herbal supplements. Keep a list to show your provider and pharmacist.
🔀 Edoxaban with other medicines, food and alcohol
The label says to discuss these with your doctor or pharmacist
- Aspirin, other antiplatelet medicines, and other blood thinners: these may increase bleeding risk. The label says long-term use of other anticoagulants is not recommended.
- Long-term (chronic) use of NSAIDs (such as ibuprofen or naproxen): may increase bleeding risk. The label says to carefully monitor patients who need long-term low-dose aspirin or NSAIDs.
- Heparin: may increase bleeding risk.
- SSRIs and SNRIs (certain antidepressants): may increase bleeding risk.
- Rifampin: the label says to avoid using it with Savaysa.
- P-gp inhibitors: for atrial fibrillation, the label says no dose reduction is recommended with these medicines. For DVT and PE, the label says a lower dose may be used with certain P-gp inhibitors.
Alcohol and food
The label says Savaysa can be taken without regard to food. The label text provided does not mention alcohol.
🤰 Edoxaban in pregnancy and breastfeeding
Pregnancy
The label says it is not known if Savaysa will harm an unborn baby. Animal studies did not show adverse developmental effects, but human data are insufficient. The label says anticoagulants may increase bleeding risk in the fetus and newborn, so newborns should be monitored for bleeding. Pregnancy also raises clot risk. Talk with your healthcare provider about pregnancy planning and about your risk of severe uterine bleeding while on blood thinners.
Breastfeeding
The label says it is not known if Savaysa passes into breast milk. It says not to breastfeed during treatment with Savaysa.
🗓️ Storage, missed doses and taking too much
Storage
Store at 20 to 25°C (68 to 77°F). Short excursions to 15 to 30°C (59 to 86°F) are permitted. Keep out of the reach of children.
If a dose is missed
The label says to take a missed dose as soon as possible on the same day. Dosing should then resume the next day on the normal schedule. The label says not to double the dose to make up for a missed dose.
If too much is taken
The label says there is no specific reversal agent for edoxaban. An overdose increases the risk of bleeding. Protamine sulfate, vitamin K, and tranexamic acid are not expected to reverse its effects. Hemodialysis does not significantly remove edoxaban. Get medical help right away if you think you have taken too much.
