  • you are allergic (hypersensitive) to remifentanil or any of the other ingredients of this medicine (listed in section 6)
  • you are allergic (hypersensitive) to any other pain-relieving medicine similar to fentanyl and related to the class of medicines known as opioids

If you are not sure if you are in one of these situations, consult your doctor, pharmacist, or healthcare professional before using Remifentanil Noridem.

Warnings and precautions:

  • you are over 65 years old
  • you are dehydrated or have lost a lot of blood

  • you or someone in your family has ever abused or been dependent on alcohol, prescription medicines, or illegal drugs ("addiction")
  • you are a smoker

If you are not sure if you are in one of these situations, consult your doctor, pharmacist, or healthcare professional before using Remifentanil Noridem.

This medicine contains remifentanil which is an opioid. Repeated use of opioids can make the medicine less effective (you get used to its effect). It can also cause dependence and abuse, which can lead to a potentially life-threatening overdose. If you are concerned that you may become dependent on Remifentanil Noridem, it is important that you talk to your doctor.

Occasionally, withdrawal reactions (e.g., rapid heartbeat, high blood pressure, and agitation) have been reported after sudden discontinuation of treatment with this medicine, especially when treatment was given for more than 3 days (see also section 4. Possible side effects). If you experience these symptoms, your doctor may restart treatment with the medicine and gradually reduce the dose.

Using Remifentanil Noridem with other medicines

Tell your doctor or pharmacist if you are using or have recently used or might use other medicines, including those bought without a prescription and herbal medicines. This is because Remifentanil Noridem can interact with other medicines, causing side effects.

  • medicines for depression, such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and monoamine oxidase inhibitors (MAOIs). It is not recommended to use these medicines at the same time as Remifentanil Noridem, as they may increase the risk of serotonin syndrome, a potentially life-threatening disease

Concomitant use of opioids and other drugs used to treat epilepsy, nerve pain, or anxiety (gabapentin and pregabalin) increases the risk of opioid overdose and respiratory depression, and can be potentially life-threatening

The following information is intended exclusively for healthcare professionals:

Consult the complete prescribing information in the Product Characteristics. The information provided in this section is the instructions for the preparation of Remifentanil Noridem before its administration and the guidelines for the infusion rates of Remifentanil Noridem for manually controlled infusion.

PREPARATION GUIDE for

Remifentanil Noridem 1 mg Powder for Concentrate for Solution for Injection or Infusion

Remifentanil Noridem is a sterile, pyrogen-free, and preservative-free lyophilized powder, white or almost white, which must be reconstituted before use. Remifentanil Noridem is available in glass vials containing 1 mg of remifentanil base. The vials should not be stored above 25°C.

When reconstituted as recommended, Remifentanil Noridem solutions are clear and colorless and contain 1 mg/mL of remifentanil base, in the form of remifentanil hydrochloride. Remifentanil Noridem should not be administered without further dilution after reconstitution of the lyophilized powder.

It is essential to read the entire content of this guide before preparing this medicinal product. This information can also be found in sections 6.4 and 6.6 of the Product Characteristics.

Reconstitution of the Lyophilized Powder

Remifentanil Noridem should be prepared for intravenous use by adding, as appropriate, 1, 2, or 5 mL of diluent (see the list of diluents in "Further Dilution") to obtain a reconstituted solution with a concentration of 1 mg/mL of remifentanil. This reconstituted solution is clear, colorless, and practically free of particles. After reconstitution, visually inspect the product (whenever the container allows) to determine the presence of particles, coloration, or container damage. Discard any solution with these defects. The reconstituted product is for single use. Any unused material should be discarded.

Further Dilution

Once reconstituted, Remifentanil Noridem should not be administered by manually controlled infusion without further dilution to concentrations of 20 to 250 micrograms/mL (50 micrograms/mL is the recommended dilution for adults and 20 to 25 micrograms/mL for pediatric patients 1 year of age or older, when used for maintenance of anesthesia). The use of Remifentanil Noridem is not recommended in pediatric patients under 18 years of age for administration of analgesia in intensive care patients with mechanical ventilation.

Once reconstituted, Remifentanil Noridem should not be administered by Target-Controlled Infusion (TCI) without further dilution (the recommended dilution for TCI is 20 to 50 micrograms/mL).

The chosen dilution depends on the technical capability of the infusion device and the patient's anticipated needs.

For dilution, one of the following intravenous fluids should be used:

Water for injections

5% Glucose solution for injection

5% Glucose and 0.9% Sodium Chloride solution for injection

0.9% Sodium Chloride solution for injection

0.45% Sodium Chloride solution for injection

After dilution, visually inspect the product to ensure it is clear, colorless, practically free of particles, and the container is not damaged. Discard any solution with these defects.

Chemical and physical stability has been demonstrated for 24 hours at 25°C. From a microbiological point of view, the product should be used immediately. If not used immediately, the storage times and conditions of the reconstituted solution prior to use are the responsibility of the user and normally should not exceed 24 hours at 2-8°C, unless the reconstitution/dilution has taken place under controlled and validated aseptic conditions.

However, Remifentanil Noridem does not contain any antimicrobial preservative, and therefore, care should be taken to ensure the sterility of the prepared solutions, and the reconstituted product should be used promptly and any unused material discarded.

Compatibility of Remifentanil Noridem has been demonstrated with the following intravenous fluids when administered through a Y-connector:

Ringer's Lactate solution for injection

Ringer's Lactate and 5% Glucose solution for injection

It has been demonstrated that Remifentanil Noridem is compatible with propofol when administered through a Y-connector.
