When This Medicine Should Not Be Used

How to Use This Medicine
- Your doctor will prescribe your exact dose and tell you how often it should be given. A nurse or other trained health professional will teach you or a caregiver how to give this medicine. The medicine is given as an infusion through a catheter that is placed directly into a vein. Do not use more medicine than your doctor tells you to.
- Your doctor or nurse will teach you how to prepare the medicine and how to use the pump for the infusion. Epoprostenol must be given continuously by a portable pump. The tube that goes into your chest is called a central venous catheter. A small pump keeps the medicine going into your body. The pump is portable, so you can move or walk while getting the medicine.
- You will be taught how to take care of the catheter and how to use the medicine and pump. It is important that you understand how to use the medicine and equipment correctly. If you have any questions, ask your doctor, nurse, or other health care provider.
- You may also want a friend or someone in your family to learn how to give your medicine.
- The medicine is a powder that needs to be mixed with a sterile (germ-free) liquid before it is given. You should not use any other liquid with the powder or mix epoprostenol with other medicines.
- Look at the medicine bag or bottle before your treatment. If you see any solid pieces or specks in the liquid or if it has changed color, you should not use it for your treatment.
- If you have your treatments at home, you should use a special container for used needles or tubes. Keep it where children or pets cannot reach it.
- During use, the mixed solution can be administered by the pump at room temperature for up to 24 hours if you mixed the entire vial with the 5 milliliter solution provided. If you are using a lower concentration, the mixture is only good for 12 hours. Protect the solution from direct sunlight.
- Ask your doctor who to call if you have any problems with the infusion pump. You may be given a second infusion pump to have in case the first pump stops working. Make sure you have access to this pump as a backup at all times.
- Use a new needle and syringe each time you inject your medicine.
- You will need to continue using this medicine for a long period of time, possibly for many years. Talk with your doctor if you have any concerns about this.
