Warnings and precautions

Talk to your doctor or nurse before you start using VasoKINOX.

  • Treatment with VasoKINOX should not be stopped abruptly.
  • Blood samples are taken before treatment and regularly during administration to monitor certain parameters.
  • There have been reports of fluid retention in the lungs with nitric oxide in patients with a disease caused by a blocked or narrow vein in the lungs. If you (as a patient) or your child (as a patient) experience shortness of breath or difficulty breathing, contact your doctor immediately.

Using VasoKINOX with other medicines

Tell your doctor if you are using, have recently used or might use any other medicines.

  • VasoKINOX should be used with caution if the following medicines are taken at the same time:
    • "Nitric oxide donors" (such as medicines containing sodium nitroprusside and nitroglycerin). Their effect may add up to that of VasoKINOX.
    • Medicines that generate methemoglobin (such as medicines containing nitrates and sulfonamides, prilocaine). They may increase the concentration of methemoglobin in the blood.
    • Prostacyclin and its analogues

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine.

Pregnancy:

The effect of administering VasoKINOX in pregnant women is unknown.

As a precautionary measure, it is preferable to avoid using VasoKINOX during pregnancy.

Breastfeeding:

It is unknown whether nitric oxide/metabolites are excreted in human milk.

A decision must be made whether to discontinue breastfeeding or discontinue therapy with VasoKINOX, taking into account the benefits of breastfeeding for the child and the benefits of therapy for the woman.

Fertility:

No fertility studies have been performed.

3. How to use VasoKINOX

Follow exactly the administration instructions of this medicine as indicated by your doctor. In case of doubt, consult your doctor again.

  • VasoKINOX is a medical gas administered only in hospitals by healthcare professionals.
  • The doctor will determine the suitable doseof VasoKINOX, as well as the duration of treatment, depending on your clinical condition and age.
  • VasoKINOX is administered by inhalation, through mechanical ventilationafter dilution in an air/oxygen mixture to patients in intensive care units with respiratory support and also in the operating room.
  • When in contact with oxygen, nitric oxide can be converted into nitrogen dioxide, which irritates the bronchi. For this reason, during its administration, the inhaled concentrations of nitric oxide and nitrogen dioxide are constantly measured.
  • In certain clinical circumstances, it is possible to administer nitric oxide through ventilation with a maskfor a very short period of time (5 to 10 minutes).

If you use moreVasoKINOXthan you should:

Your doctor will take the necessary measures.

If you stop treatment withVasoKINOX:

At the end of treatment in intensive care, the doctor will gradually reduce the dose of VasoKINOX administered (withdrawal phase), monitoring the change in your condition.

In fact, an abrupt interruption of treatment after several hours of administration can cause a deterioration of the clinical condition: this is what is called a "rebound effect".

If you have any other questions about the use of this medicine, ask your doctor or nurse.

--------------------------------------------------------------------------------------------------------------------

This information is intended only for healthcare professionals:

To avoid any incidents, the following instructions must be strictly followed:

. Check that the equipment is in good condition before use

. Securely fasten the cylinders using chains or hooks in the basket to avoid accidental falls

. Never open a valve abruptly: open to the left, slowly and completely, then turn the valve a quarter turn

. Do not handle a cylinder whose valve is not protected by a tulip or protection system

. Use a specific ISO 5245 (2004) connector: No. 29 specific NO/N2 (100 ppm

. A pressure regulator that can withstand a pressure at least equal to 1.5 times the maximum operating pressure (200 bar) of the gas cylinder must be used

. For each new use, purge the pressure reducer/flow meter using a nitric oxide/nitrogen mixture

. Do not attempt to repair a faulty valve

. Do not tighten the pressure reducer/flow meter using a clamp, otherwise the seal may be damaged and the administration device may be damaged

. Evacuate exhaled gases to the outside (avoiding areas where they can accumulate). Before use, it must be ensured that the room has an adequate ventilation system for the evacuation of gases in case of an accident or accidental leaks

. Since nitric oxide is colorless and odorless, the use of a detection system is recommended in all rooms where it will be used or stored

. European reference agencies responsible for occupational safety and health recommend the following exposure limits for medical personnel during 8 hours:

  • NO: 2 ppm (2.5 mg/m3)
  • NO2: 0.5 ppm (0.96 mg/m3)

To comply with the above recommendations, an analysis of nitric oxide and nitrogen dioxide in the atmosphere must be implemented.

. The installation of a nitric oxide piping system with a gas cylinder supply source, fixed network, and terminal units is prohibited.
