Epoprostenol Dosing Guidelines
Epoprostenol is used to treat a variety of conditions. Below are the recommended doses for adults. Always consult your healthcare provider before adjusting your dose. Our telemedicine providers are available to assist with any questions or concerns you may have.
Pulmonary Arterial Hypertension (PAH)
The initial dose is 2 ng/kg/min, administered via continuous intravenous infusion. The dose is gradually increased based on the patient’s response and tolerance. Maintenance doses typically range from 25-40 ng/kg/min.
Raynaud’s Phenomenon

Epoprostenol may be used off-label for heart failure. Dosing is individualized and should be closely monitored by your healthcare provider.
Thromboangiitis Obliterans (Buerger’s Disease)
The initial dose is 2 ng/kg/min by continuous intravenous infusion, with gradual increases as tolerated.
Scleroderma
Dosing is individualized, typically starting at 2 ng/kg/min by continuous intravenous infusion.
Eisenmenger Syndrome
Dosing is individualized based on the patient’s condition. Consult your healthcare provider for specific dosing instructions.
Atherosclerosis
Dosing is individualized and should be discussed with your healthcare provider.
Chronic Obstructive Pulmonary Disease (COPD)
Epoprostenol is not commonly used for COPD, but if prescribed, the dose is individualized. Consult your healthcare provider for specific dosing recommendations.
Dosage Forms and Strengths
Powder for solution (for intravenous infusion): 0.5 mg, 1.5 mg
Epoprostenol Administration Guidelines
Epoprostenol is administered through continuous intravenous infusion, delivered directly into the bloodstream via a small tube (catheter). A specialized infusion pump ensures the correct dose is delivered at the appropriate rate. It is essential to follow your healthcare provider’s instructions carefully and never stop the medication abruptly, as this can lead to serious complications. If you have any questions about administering Epoprostenol or managing your infusion, our telemedicine providers are available to assist you.
Epoprostenol Side Effects and Adverse Reactions
Like all medications, Epoprostenol can cause side effects. Below are some common and serious side effects. If you experience any of these symptoms, contact your healthcare provider immediately. Our telemedicine providers are available to help address any concerns.
Common Side Effects
- Flushing: A warm, red sensation in the skin, often noticeable on the face.
- Headache: Mild to moderate headaches are frequently reported.
- Nausea: A feeling of sickness or discomfort in the stomach.
- Jaw pain: Discomfort or pain in the jaw, particularly when eating.
Serious Side Effects
- Low blood pressure (hypotension): Symptoms may include dizziness, fainting, or feeling lightheaded.
- Bleeding: An increased risk of bleeding, especially if you are taking blood thinners.
- Infection at the infusion site: Signs include redness, swelling, or pain at the catheter site.
- Heart palpitations: Irregular or rapid heartbeats.
Contraindications for Epoprostenol Therapy
A contraindication is a specific condition where a medication should not be used because it may cause harm. For Epoprostenol, there are several contraindications to consider before starting treatment. These should be discussed with your healthcare provider, especially during telemedicine consultations.
Heart Failure Due to Severe Left Ventricular Dysfunction
Epoprostenol is contraindicated in patients with heart failure caused by severe left ventricular dysfunction. The medication can increase the risk of fluid buildup in the lungs (pulmonary edema), which may worsen heart failure.
Hypersensitivity to Epoprostenol or Its Components
If you are allergic to Epoprostenol or any of its ingredients, you should not take this medication. Allergic reactions can range from mild to severe, including symptoms such as rash, swelling, or difficulty breathing.
Bleeding Disorders
Epoprostenol can increase the risk of bleeding by affecting how platelets function. If you have a bleeding disorder or are at high risk for bleeding, this medication may not be safe for you.
Drug to Drug Interactions
It is essential to inform your healthcare provider about all the medications you are currently taking, as Epoprostenol can interact with other drugs. Some medications may increase the risk of side effects or reduce the effectiveness of Epoprostenol therapy. Below are some important drug interactions to be aware of:
Anticoagulants (e.g., Warfarin, Heparin): Epoprostenol can heighten the risk of bleeding when used with blood thinners like Warfarin (Coumadin) or Heparin. Your doctor may need to adjust your dosage or monitor you more closely to ensure your safety.
Antiplatelet drugs (e.g., Aspirin, Clopidogrel): These medications also affect platelet function, and when combined with Epoprostenol, they can further increase the risk of bleeding.
Vasodilators (e.g., Nitroglycerin, Sildenafil): Epoprostenol lowers blood pressure, and taking it alongside other medications that also reduce blood pressure, such as Nitroglycerin (Nitrostat) or Sildenafil (Viagra), can lead to dangerously low blood pressure (hypotension).
Epoprostenol in Pregnancy
Is it safe to take Epoprostenol during pregnancy?
There is limited information on the use of Epoprostenol during pregnancy. While animal studies have not shown direct harm to the fetus, there is insufficient evidence to confirm its safety in pregnant humans. Epoprostenol treatment is typically prescribed during pregnancy only if the potential benefits outweigh the risks. If you are pregnant or planning to become pregnant, it is crucial to discuss this with your healthcare provider. You can also schedule a telemedicine appointment with one of our providers to explore your options.
Epoprostenol while Breastfeeding
Is it safe to take Epoprostenol while breastfeeding?
It is not known whether Epoprostenol passes into breast milk. Due to the lack of available data, breastfeeding mothers are generally advised to avoid using Epoprostenol therapy or consult their healthcare provider to carefully weigh the potential risks and benefits. If you are breastfeeding, please reach out to one of our telemedicine providers to discuss your treatment options.
Estimated Cost of Epoprostenol
The estimated cost of a 30-day supply of Epoprostenol without insurance can vary. However, with a GoodRX coupon, the price may range from $2,000 to $3,000, depending on the pharmacy and dosage. Be sure to check with your pharmacy for the most accurate pricing. For more information on Epoprostenol cost and insurance coverage, consult your healthcare provider or pharmacist.
Possible Alternatives to Epoprostenol
If Epoprostenol is not suitable for you, there are alternative treatments and lifestyle changes that may help manage your condition. Always discuss these options with your healthcare provider before making any changes to your treatment plan. You can also consult one of our telemedicine providers for personalized advice.
- Pulmonary arterial hypertension: Alternatives include other pulmonary vasodilators such as Sildenafil (Revatio), Tadalafil (Adcirca), or Bosentan (Tracleer). Lifestyle changes like regular exercise and a low-sodium diet may also help manage symptoms.
- Raynaud’s phenomenon: Calcium channel blockers like Nifedipine (Procardia) or lifestyle changes such as avoiding cold exposure and managing stress can be effective alternatives.
- Peripheral vascular disease: Medications like Cilostazol (Pletal) or Pentoxifylline (Trental) may be used. Regular exercise and smoking cessation are also important lifestyle changes.
- Coronary artery disease: Statins, beta-blockers, and antiplatelet drugs like Aspirin may be alternatives. A heart-healthy diet, regular exercise, and quitting smoking are key lifestyle changes.
- Heart failure: ACE inhibitors, beta-blockers, and diuretics are common alternatives. Reducing salt intake and maintaining a healthy weight are essential lifestyle changes.
- Thromboangiitis obliterans: Smoking cessation is the most important lifestyle change. Medications like vasodilators or anticoagulants may also be prescribed.
- Scleroderma: Immunosuppressants and other vasodilators may be alternatives. Protecting your skin from cold and moisturizing regularly are important lifestyle changes.
- Eisenmenger syndrome: Treatment options may include oxygen therapy, anticoagulants, or heart-lung transplantation in severe cases. Avoiding high altitudes and strenuous exercise can help manage symptoms.
- Atherosclerosis: Statins, antiplatelet drugs, and lifestyle changes such as a heart-healthy diet, regular exercise, and quitting smoking are key alternatives.
- Chronic obstructive pulmonary disease (COPD): Bronchodilators, inhaled steroids, and oxygen therapy may be alternatives. Quitting smoking and pulmonary rehabilitation are critical lifestyle changes.
