How Long to Take Eliquis For Pulmonary Embolism?
The duration of Eliquis treatment for a pulmonary embolism (PE) varies, but typically lasts for at least 3 to 6 months, and may be longer or even indefinite depending on the underlying cause and individual risk factors. Understanding these factors is critical in determining how long to take Eliquis for pulmonary embolism.
Understanding Pulmonary Embolism and Eliquis
A pulmonary embolism (PE) is a serious condition where a blood clot travels to the lungs, blocking blood flow. Eliquis (apixaban) is an anticoagulant (blood thinner) that helps prevent new clots from forming and existing clots from growing. It does not dissolve clots that are already present but allows the body’s natural mechanisms to break them down over time. Determining how long to take Eliquis for pulmonary embolism is a complex decision made in consultation with a physician.
Benefits of Eliquis for PE Treatment
Eliquis offers several advantages in treating PEs:
- Effective clot prevention: Significantly reduces the risk of recurrent PE and deep vein thrombosis (DVT).
- Oral administration: Convenient compared to injectable anticoagulants like heparin.
- Lower risk of bleeding: Generally associated with a lower risk of major bleeding compared to warfarin (Coumadin) in clinical trials, although bleeding risk is still present.
- No routine monitoring: Unlike warfarin, Eliquis doesn’t usually require regular blood tests to monitor its effectiveness.
Determining the Duration of Eliquis Treatment
The decision of how long to take Eliquis for pulmonary embolism hinges on several factors, primarily the cause of the PE and the patient’s risk of bleeding.
- Provoked PE: A PE that occurs due to a known, temporary risk factor (e.g., surgery, trauma, prolonged immobilization). In these cases, treatment typically lasts for 3 to 6 months.
- Unprovoked PE: A PE that occurs without a clear identifiable risk factor. The treatment duration for unprovoked PEs is often longer, potentially indefinite, as the risk of recurrence is higher.
- PE Associated with Active Cancer: Patients with cancer-associated PEs often require long-term anticoagulation, often for as long as the cancer is active. Eliquis may be a suitable option in these cases.
- Bleeding Risk: A careful assessment of a patient’s bleeding risk is essential. Factors that increase bleeding risk include:
- Advanced age
- History of bleeding
- Kidney or liver disease
- Concomitant use of antiplatelet medications (e.g., aspirin, clopidogrel)
- Certain medical conditions (e.g., peptic ulcer disease).
- Alcohol abuse
The Process of Deciding Treatment Duration
The process for deciding how long to take Eliquis for pulmonary embolism usually involves the following steps:
- Initial Diagnosis and Treatment: PE is diagnosed via imaging studies (e.g., CT pulmonary angiogram). Eliquis is typically started immediately after diagnosis.
- Evaluation of Risk Factors: The physician will thoroughly investigate the potential causes of the PE and assess the patient’s bleeding risk.
- Treatment Plan Discussion: The doctor will discuss the benefits and risks of different treatment durations with the patient.
- Regular Monitoring: During Eliquis treatment, the patient should be monitored for signs and symptoms of bleeding or recurrent clots.
- Treatment Duration Adjustment: The duration of Eliquis treatment may be adjusted based on the patient’s response to treatment, changes in risk factors, and any adverse events.
Common Mistakes and Misconceptions
- Stopping Eliquis prematurely: Stopping Eliquis without consulting a doctor, even if feeling better, can increase the risk of recurrent PE.
- Ignoring bleeding symptoms: Any unusual bleeding (e.g., nosebleeds, blood in urine or stool, excessive bruising) should be reported to a doctor immediately.
- Assuming all PEs are treated the same: As previously mentioned, the duration of treatment varies depending on the cause and risk factors.
- Thinking Eliquis dissolves existing clots: Eliquis prevents new clots and stops existing ones from growing. The body clears the clot over time.
Alternatives to Eliquis
While Eliquis is a commonly prescribed medication for PE, other options exist:
- Warfarin (Coumadin): A vitamin K antagonist requiring regular blood monitoring.
- Other Direct Oral Anticoagulants (DOACs): Such as rivaroxaban (Xarelto), dabigatran (Pradaxa), and edoxaban (Savaysa).
- Heparin: Injectable anticoagulant, often used initially in the hospital setting.
- Low Molecular Weight Heparin (LMWH): Another injectable anticoagulant, such as enoxaparin (Lovenox). Often used for cancer-associated thrombosis.

Frequently Asked Questions (FAQs)
What are the potential side effects of Eliquis?
The most common side effect of Eliquis is bleeding. This can range from minor bruising to more serious bleeding events. Other possible side effects include allergic reactions, nausea, and anemia. It’s crucial to report any unusual bleeding or other concerning symptoms to your doctor immediately.
Is it safe to take Eliquis during pregnancy?
Eliquis is generally not recommended during pregnancy due to the potential risks to the fetus. Alternative anticoagulants, such as low molecular weight heparin, may be considered. This decision should be made in consultation with your doctor.
Can I take other medications with Eliquis?
Eliquis can interact with certain medications, increasing the risk of bleeding or reducing its effectiveness. It’s essential to inform your doctor about all medications, including over-the-counter drugs, herbal supplements, and vitamins, before starting Eliquis.
What should I do if I miss a dose of Eliquis?
If you miss a dose of Eliquis, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and take your next dose at the regular time. Do not double your dose to make up for a missed one.
How often should I see my doctor while taking Eliquis?
Regular follow-up appointments with your doctor are important while taking Eliquis. The frequency of these appointments will depend on your individual medical history and risk factors. Your doctor will monitor your response to treatment and watch for any potential side effects.
Can I drink alcohol while taking Eliquis?
Moderate alcohol consumption may be acceptable while taking Eliquis, but it’s best to discuss this with your doctor. Excessive alcohol intake can increase the risk of bleeding.
What happens if I need surgery or a dental procedure while taking Eliquis?
You may need to temporarily stop taking Eliquis before surgery or certain dental procedures to reduce the risk of bleeding. Always inform your surgeon or dentist that you are taking Eliquis. Your doctor will provide specific instructions on when to stop and restart the medication.
How will I know if my pulmonary embolism is getting better while on Eliquis?
Symptoms of PE, such as shortness of breath and chest pain, should gradually improve with treatment. Your doctor may also order follow-up imaging studies to assess the clot’s resolution.
What is the risk of recurrent pulmonary embolism after stopping Eliquis?
The risk of recurrent PE varies depending on the underlying cause of the initial clot. Individuals with unprovoked PEs have a higher risk of recurrence than those with provoked PEs.
What are the signs and symptoms of a new pulmonary embolism?
Signs and symptoms of a new PE may include:
- Sudden shortness of breath
- Chest pain, especially with deep breathing
- Coughing up blood
- Rapid heartbeat
- Lightheadedness or fainting
If you experience any of these symptoms, seek immediate medical attention.
Are there any lifestyle changes I should make while taking Eliquis?
While on Eliquis, it is important to inform all of your healthcare providers that you are taking an anticoagulant, wear medical alert identification, take precautions to prevent injury and falls, and maintain a consistent diet. Check with your doctor about specific dietary restrictions or supplement use.
Does Eliquis interact with any foods?
Eliquis does not have any significant food interactions, unlike warfarin, which requires careful monitoring of vitamin K intake. However, it’s always a good idea to maintain a balanced diet and avoid excessive alcohol consumption.
