1. What is Neophyr and what is it used for

Neophyr is a gas mixture for inhalation use.

Neophyr is a medicinal compressed gas consisting of a gas mixture containing 225 ppm, 450 ppm or 1000 ppm mol/mol of nitric oxide.

What is it used for?

Neophyr should be administered exclusively by healthcare professionals and is intended for strictly hospital use.

Neophyr is indicated in the following cases:

  • Newborn babies with pulmonary insufficiency associated with high blood pressure in the lungs, a health problem known as hypoxic respiratory failure. By inhaling it, the gas mixture can improve blood flow within the lungs, which can contribute to increasing the amount of oxygen that reaches the baby's blood.
  • Newborn babies, babies, children, and adolescents from 0 to 17 years and adults with high blood pressure in the lungs related to heart surgery. This gas mixture can improve heart function and increase blood flow within the lungs.

2. What you need to know before you use Neophyr

Do not use Neophyr:

  • If you are allergic to nitric oxide or any of the other components of this medicine (listed in section 6).
  • If you have been told that you (as a patient) or your child (as a patient) have abnormal circulation in the heart.
  • If you (as a patient) or your child (as a patient) have a congenital or acquired deficiency of methemoglobin reductase (MetHb reductase) or glucose-6-phosphate dehydrogenase (G6PD).

Warnings and precautions

Consult your doctor before starting to use Neophyr.

Inhaled nitric oxide may not be effective in all cases, so other therapies may be considered necessary for you or your child.

Inhaled nitric oxide can affect the blood's ability to transport oxygen. This function will be monitored through blood sampling, and if necessary, the dose of inhaled nitric oxide will be reduced.

Nitric oxide can react with oxygen to form nitrogen dioxide, which can cause irritation of the respiratory tract. The doctor treating you or your child will monitor the nitrogen dioxide levels and, if high values are detected, will adjust the Neophyr therapy or reduce it as necessary.

Inhaled nitric oxide can mildly affect the platelets (components that contribute to blood clotting) in your body or that of your child, so the appearance of any signs of bleeding and/or bruising should be supervised. If you notice any signs or symptoms that may be associated with bleeding, you should inform your doctor directly.

No effects of inhaled nitric oxide have been documented in newborn babies with a malformation that means the diaphragm is not fully present (also called "congenital diaphragmatic hernia").

In newborn babies with special heart malformations, what doctors call "congenital heart disease", inhaled nitric oxide can cause a worsening of circulation.

Cases of fluid retention in the lungs have been reported with the use of nitric oxide in patients with disease caused by a blocked or narrow vein in the lungs. If you (as a patient) or your child (as a patient) develop shortness of breath or difficulty breathing, contact your doctor immediately.

Children

Neophyr should not be used in premature babies with a gestational age of less than 34 weeks.

Using Neophyr with other medicines

Your doctor will decide when to treat you or your child with Neophyr and other medicines, as well as carefully monitor the treatment.

Tell your doctor if you (as a patient) or your child (as a patient) are taking, have recently taken, or may need to take any other medicine.

Some medicines can affect the blood's ability to transport oxygen. These include prilocaine (a local anesthetic used to relieve pain in minor painful procedures, such as suturing and minor surgical or diagnostic procedures) or glyceryl trinitrate (used to treat chest pain). Your doctor will check that the blood can transport enough oxygen while you are using these medicines.

Pregnancy, breastfeeding, and fertility

Neophyr should not be used during pregnancy unless clearly necessary, such as in situations where life-support equipment is required.

Exposure to nitric oxide should be avoided in humans during breastfeeding.

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

3. How to use Neophyr

Your doctor will decide on the correct dose of Neophyr and administer Neophyr to you or your child in the lungs through a system designed for the administration of this gas. This system will ensure the administration of the correct amount of nitric oxide by diluting Neophyr with an oxygen/air mixture immediately before administering it to the patient.

For your safety (or that of your child), the systems designed for Neophyr administration are equipped with devices that constantly measure the amount of nitric oxide, oxygen, and nitrogen dioxide (a chemical substance that forms when nitric oxide is mixed with oxygen) administered to the lungs.

Your doctor will decide how long the treatment with Neophyr should last for you or your child.

The recommended dose of Neophyr is 10 to 20 ppm (with a maximum dose for children of 20 ppm and for adults of 40 ppm) parts per million of the gas that you or your child inhale. The lowest effective dose will be used.

Therapy is usually required for about 4 days in newborn babies with pulmonary insufficiency associated with high blood pressure in the lungs. In children and adults with high blood pressure in the lungs associated with heart surgery, Neophyr is usually administered for 24-48 hours. However, Neophyr therapy may last longer.

If you use more Neophyr than you should

Excessive inhalation of nitric oxide can affect the blood's ability to transport oxygen. This function will be monitored through blood sampling, and if necessary, the dose of Neophyr will be reduced, and the administration of medicines such as vitamin C, methylene blue, or, if necessary, a blood transfusion, will be considered to improve the blood's oxygen transport capacity.

If you stop using Neophyr

Treatment with Neophyr should not be stopped suddenly. It has been observed that low blood pressure or a rebound effect of increased pressure in the lungs occurs if Neophyr treatment is stopped suddenly without first reducing the dose.

At the end of treatment, your doctor will gradually reduce the amount of Neophyr prescribed for you or your child, so that lung circulation can adjust to the amount of oxygen/air without Neophyr. Consequently, this may take one or two days before you or your child finish treatment with Neophyr.

Follow your doctor's instructions for administering this medicine exactly. If you are in doubt, ask your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Your doctor will closely monitor and supervise any type of side effect. It is unlikely that you will suffer from these side effects.

The side effects that occur very frequently (affect more than 1 in 10 patients) associated with Neophyr therapy include:

  • Low platelet count, abnormally low potassium concentration in the blood (hypokalemia), low blood pressure, shortness of breath or lung collapse, abnormally high levels of bilirubin in the blood.

The side effects that may occur, but whose frequency is not known (cannot be estimated from the available data) are:

  • Rebound effect of high blood pressure in the lungs (increase in pulmonary arterial pressure) and low oxygen levels in the blood (oxygen desaturation/hypoxemia) due to sudden withdrawal of treatment; increased methemoglobin and, therefore, decreased oxygen transport capacity.
  • Accidental exposure of nitric oxide to the ambient air, e.g., due to equipment or cylinder leakage, may cause headache.

You should inform the staff directly if you experience a headache while you are near your child when Neophyr is being administered.

If any of the side effects become serious, or if you notice any side effects not listed in this leaflet, tell your doctor.

If you have any further questions on the use of this product, ask your doctor or other healthcare professionals.

Reporting side effects

If you get any side effects, talk to your doctor. This includes any possible side effects not listed in this leaflet. You can also report side effects directly through the Spanish Medicines and Healthcare Products Agency's (AEMPS) online system: www.notificaRAM.es.

By reporting side effects, you can help provide more information on the safety of this medicine.
