What EPOPROSTENOL MYX is used for
Epoprostenol is used to treat some types of pulmonary arterial hypertension (PAH). PAH is characterised by high blood pressure in the blood vessel that carries blood from the heart to the lungs, and increased resistance in the blood vessels of the lung. The cause of PAH is not known however there are a number of diseases such as scleroderma that are associated with PAH. Epoprostenol belongs to a group of medicines called prostaglandins.
Epoprostenol works by widening the blood vessels in the lungs and so lowering the blood pressure in your lungs (known as a vasodilator action).
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
Epoprostenol is not addictive.

How to use EPOPROSTENOL MYX
EPOPROSTENOL MYX will be given as an intravenous infusion only, normally through a permanently fitted intravenous catheter (during initial treatment a 'peripheral line' may be used which is a non-permanent catheter). Before EPOPROSTENOL MYX is used, it must be dissolved only in the specific DILUENT supplied with EPOPROSTENOL MYX.
How much to use
Initial treatment with EPOPROSTENOL MYX will be carried out in a hospital. Your doctor will start you on an infusion and slowly increase the dose (every 15 minutes) to find the most effective or largest dose you can tolerate. During this part of the treatment you will also learn about how your body reacts to EPOPROSTENOL MYX.
Your doctor will then continue the infusion based on this dose, and may increase or decrease your infusion rate depending on your response to the treatment. All changes should be done gradually and under the direction of a doctor, except in emergency situations.
If you develop pulmonary oedema (water on the lungs) during this time, your doctor may choose not to treat you with EPOPROSTENOL MYX.
How to use it
Your EPOPROSTENOL MYX infusion will be given to you as continuous intravenous infusion only, normally through a permanently fitted intravenous catheter through a pump. There are only certain pumps which can be used. Your doctor will make sure you are using the right one.
Your doctor or nurse will have shown you how to keep your catheter clean, and the area around it clean and free from infection. They will also show you how to prepare and administer e and how to stop treatment if necessary. It is very important you follow their instructions carefully.
The DILUENT contains no preservative. Use a vial once only and then discard.
How long to use it
Use EPOPROSTENOL MYX for as long as your doctor advises you to. EPOPROSTENOL MYX is generally used over a prolonged period of time, possibly years. It should not be stopped suddenly. Symptoms of suddenly stopping EPOPROSTENOL MYX include dizziness, weakness and difficulty breathing.
If you use too much (overdose)
As EPOPROSTENOL MYX has vasodilatory action, overdose may lead to low blood pressure, loss of consciousness, nausea, diarrhoea, vomiting, facial flushing, headache and fast heart beat.
In hospital, the effects of EPOPROSTENOL MYX are monitored carefully by your doctor. In the unlikely event that you receive too much, appropriate action, such as reducing the dose can be taken promptly.
If you are using EPOPROSTENOL MYX at home and you think you have used too much, immediately telephone your doctor or the nearest hospital casualty department, even if there are no signs of discomfort. You may need urgent medical attention.
Keep telephone numbers for these places handy.
