Patient leaflet - Veletri 1.5 mg powder for solution for infusion

1. What VELETRI is and what it is used for

VELETRI contains the active substance epoprostenol, which belongs to a group of medicines called prostaglandin, which stops blood from clotting and widens the blood vessels.

VELETRI is used to treat a lung condition called ‘pulmonary arterial hypertension’. This is where the pressure is high in the blood vessels in the lungs. VELETRI widens the blood vessels to lower the blood pressure in the lungs.

VELETRI is used to prevent blood clotting during kidney dialysis when heparin cannot be used.

2. What you need to know before you use VELETRI

Do not use VELETRI

  • if you are allergic to VELETRI or any of the other ingredients of this medicine (listed in section 6).
  • if you have heart failure.
  • if you start to develop a build-up of fluid in your lungs causing breathlessness after starting this treatment.

If you think any of these apply to you, don’t take VELETRI until you have checked with your doctor.

Warnings and precautions

Talk to your doctor before using VELETRI.

Before you are given VELETRI your doctor needs to know:

  • if you have any problems with bleeding.

Skin damage at the injection site

VELETRI is injected into a vein. It is important that the medicine does not leak out of the vein into the surrounding tissue. If it does, the skin could be damaged. The symptoms of this are:

  • tenderness
  • burning
  • stinging
  • swelling
  • redness.

This may be followed by blistering and shedding of the skin. While you are being treated with VELETRI, it is important that you check the injection area.

Contact the hospital immediately for advice if the area becomes sore, painful or swollen or you notice any blistering or shedding.

Effect of VELETRI on blood pressure and heart rate

VELETRI can cause your heart to beat faster or slower. Also your blood pressure can become too low. While you are being treated with VELETRI, your heart rate and blood pressure will be checked. The symptoms of low blood pressure include dizziness and fainting.

Tell your doctor if you get these symptoms. Your dose may need to be reduced or your infusion stopped.

Children and adolescents

The safety and efficacy of VELETRI in children have not yet been established.

Other medicines and VELETRI

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

Some medicines may affect how VELETRI works, or make it more likely that you’ll have side effects. VELETRI can also affect how some other medicines work if taken at the same time. These include:

  • medicines used to treat high blood pressure
  • medicines used to prevent blood clots
  • medicines used to dissolve blood clots
  • medicines to treat inflammation or pain (also called ‘NSAIDs’)
  • digoxin (used to treat heart disease).

Tell your doctor or pharmacist if you are taking any of these.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine as your symptoms could worsen during pregnancy.

It is not known whether the ingredients of VELETRI can pass into breast-milk. You should stop breastfeeding your child during treatment with VELETRI.

Driving and using machines

Your treatment may have an effect on the ability to drive or use machinery.

Don’t drive or use machines unless you’re feeling well.

VELETRI contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially ‘sodium-free’.

3. How to take VELETRI

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

VELETRI comes as a powder in a small glass vial. The powder needs to be dissolved before use.

VELETRI should not be given as a quick injection into your vein. It should always be given as an intravenous infusion.

Your doctor will decide how much VELETRI is right for you. The amount you are given is based on your body weight, and your type of illness. Your dose may be increased or decreased depending on how well you respond to treatment.

VELETRI is given by slow infusion (drip) into a vein.

Pulmonary arterial hypertension

Your first treatment will be given to you in a hospital. This is because your doctor needs to monitor you and find the best dose for you.

You will start with an infusion of VELETRI. The dose will be increased, until your symptoms are relieved, and any side effects are manageable. Once the best dose has been found, a permanent tube (line) will be fitted into one of your veins. You can then be treated using an infusion pump.

Kidney dialysis

You will be given an infusion of VELETRI for the duration of your dialysis.

Using VELETRI at home (only for treatment of Pulmonary Arterial Hypertension)

If you are treating yourself at home, your doctor or nurse will show you how to prepare and use VELETRI. They will also advise you how to stop treatment if necessary. Stopping VELETRI must be done gradually. It is very important that you follow all their instructions carefully.

VELETRI comes as a powder in a glass vial. Before use, the powder needs to be dissolved in a liquid. The liquid does not contain a preservative. If you have any of the liquid left over, it must be thrown away.

Looking after the injection line

If you have been fitted with a ‘line’ into a vein, it is very important to keep this area clean, otherwise you could get an infection. Your doctor or nurse will show you how to clean your ‘line’ and the area around it. It is very important that you follow all of their instructions carefully. It is also very important that you carefully follow all instructions regarding the change of the pump drug delivery reservoir (cassette) and that you always use an extension set with an in-line filter, as instructed by your doctor to reduce the risk of an infection. When reconnecting your extension set, always ensure that any excess drops are wiped off so that there is no liquid in the exterior space between the extension set and the injection line connectors, as it may damage the materials.

If you take more VELETRI than you should

Seek urgent medical attention if you think you have used or been given too much VELETRI. Symptoms of overdose may include headache, nausea, vomiting, fast heart rate, warmth or tingling, or feeling like you might pass out (feeling faint/dizziness).

If you forget to take VELETRI

Do not take a double dose to make up for a forgotten dose.

If you stop taking VELETRI

Stopping VELETRI must be done gradually. If the treatment is stopped too quickly you may get serious side effects, including dizziness, feeling weak and breathing difficulties. If you have problems with the infusion pump or an injection line that stops or prevents treatment with VELETRI, contact your doctor, nurse or hospital immediately.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist or nurse.

  • One vial containing sterile, freeze-dried VELETRI equivalent to 0.5 mg VELETRI supplied alone.
  • One vial containing sterile, freeze-dried VELETRI equivalent to 1.5 mg VELETRI supplied alone.

Reconstitution:

Withdraw 5 mL of either Sterile Water for Injection or Sodium Chloride 0.9% Injection diluent into a sterile syringe, inject the contents of the syringe into the vial containing VELETRI and shake gently until the powder has dissolved. The reconstituted solution should be examined prior to further dilution. Its use is forbidden in the presence of discolouration or particles. Any unused reconstituted solution should be disposed of in accordance with local requirements.

Dilution:

The reconstituted solution should be immediately further diluted to the final concentration. Further dilution should be performed with the same diluent as used for reconstitution of the sterile, lyophilised powder.

VELETRI when administered chronically, should be prepared in a drug delivery reservoir appropriate for the infusion pump.

Suitable ambulatory pumps to be used for the administration of VELETRI include:

  • CADD-Legacy 1
  • CADD-Legacy PLUS
  • CADD-Solis VIP (variable infusion profile)

Manufactured by Smiths Medical.

Pump accessories found to be compatible with the administration of VELETRI include:

  • CADD disposable Medication Cassette Reservoir 50 mL; 100 mL from Smiths Medical.
  • CADD extension set with in-line 0.2 micron filter (CADD extension set with male luer, 0.2- micron air-eliminating filter, clamp, and integral anti-siphon valve with male luer) from Smiths Medical.

Based on available data from inhouse testing and manufacturer accessories instructions for use, preparation and administration materials likely to be compatible include:

  • Acrylic
  • Acrylonitrile butadiene styrene (ABS)
  • Polycarbonate
  • Polyethersulfone
  • Polypropylene
  • Polytetrafluoroethylene (PTFE)
  • Polyurethane
  • Polyvinyl chloride (PVC) (plasticised with DEHP)
  • Silicone

It is unknown if polyethylene terephthalate (PET) and polyethylene terephthalate glycol (PETG) are compatible with VELETRI since these materials have not been tested with VELETRI, therefore the use of these materials is not recommended.

Only extension sets with an in-line 0.22 micron filter placed between the infusion pump and the catheter must be used. It is recommended to use filters with a hydrophilic polyethersulfone membrane. The extension set and the in-line filter must be changed at least every 48 hours.

The vial containing 0.5 mg epoprostenol must be used for the preparation of solutions with final concentrations below 15 000 ng/mL.
