Do not use Remifentanilo Noridem if:

  • 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 any of the above situations, consult your doctor, pharmacist or healthcare professional before using Remifentanilo Noridem.

Warnings and precautions:

Talk to your doctor or pharmacist before you start using Remifentanilo Noridem if:

  • you are allergic (hypersensitive) to any other opioid medicine, such as morphine or codeine
  • you are over 65 years old
  • you are dehydrated or have lost a lot of blood
  • you have not been feeling well or have been feeling weak
  • you are overweight
  • you or someone in your family has ever abused or been dependent on alcohol, prescription medicines or illegal drugs ("addiction")
  • you are a smoker
  • you have ever had mood problems (depression, anxiety or personality disorder) or have been treated by a psychiatrist for other mental illnesses

If you are not sure if you are in any of the above situations, consult your doctor, pharmacist or healthcare professional before using Remifentanilo 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 Remifentanilo 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 Remifentanilo Noridem with other medicines

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

It is especially important that you tell your doctor or pharmacist if you are taking:

  • medicines to control blood pressure or heart problems, such as beta-blockers (including atenolol, metoprolol, carvedilol, propranolol and bisoprolol) or calcium channel blockers (including amlodipine, diltiazem and nifedipine)
  • medicines to treat depression, such as selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs) and monoamine oxidase inhibitors (MAOIs). It is not recommended to use these medicines at the same time as Remifentanilo 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

Pregnancy and breastfeeding

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

If you receive this medicine during childbirth or shortly before delivery, it may affect your baby's breathing. You and your baby will be monitored for signs of excessive sleepiness or difficulty breathing

Driving and using machines

If you are only in the hospital during the day, your doctor will tell you how long you should wait before leaving the hospital or driving. It may be dangerous to drive too soon after having an operation

This medicine may affect your ability to drive because it can make you feel drowsy or dizzy

Andrei Popov

General medicinePain medicine7 years of experience

Dr. Andrei Popov is a General Practitioner with specialized training in chronic pain. He provides online consultations for adult patients in Spain and other European countries.

Dr. Popov understands that seeking help with weight-related concerns or pain that has persisted for months can be difficult. Many patients come to him after trying different approaches without feeling truly heard. During the consultation, the doctor creates a comfortable and supportive, non-judgmental environment where the patient’s medical history can be discussed in detail, questions can be answered, and the next steps can be decided together.

Weight Management and Metabolic Health

Dr. Popov can help assess overweight, obesity, and related conditions such as hypertension, diabetes, or metabolic disorders. During the consultation, the patient’s medical history, test results, current medications, and previous treatments will be reviewed.

If you would like to learn about possible medication options or have already started treatment, the doctor can assess your situation, review the effectiveness and tolerability of the therapy, and clearly explain its benefits, potential risks, and alternatives.

Not every patient requires the same treatment. A consultation does not guarantee a prescription — it provides an objective medical assessment and a plan tailored to your individual situation.

Pain and General Medicine

You can also consult Dr. Popov regarding:

* chronic pain, migraines, neuralgia, and fibromyalgia;

* back, neck, lower back, or joint pain;

* hypertension, diabetes, and follow-up of chronic conditions;

* review of test results, medical reports, and current treatment;

* preventive medicine and a second medical opinion.

How the Consultation Works

The video consultation lasts up to 30 minutes. The doctor will listen carefully, review the information you provide, and explain the next steps in clear and understandable language.

If additional tests, an in-person consultation, or urgent medical care are required, the doctor will inform you directly.

Dr. Popov’s goal is to make sure the patient feels heard and leaves the consultation with a clear understanding of their condition and the next steps they can take.

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 according to the recommendations, the 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 performing an additional 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 Technical Sheet.

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 "Additional 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 packaging allows) to determine the presence of particles, coloration, or deterioration of the packaging. Discard any solution in which such defects are observed. The reconstituted product is for single use. Any unused material should be discarded.

Additional Dilution

Once reconstituted, Remifentanil Noridem should not be administered by manually controlled infusion without performing an additional 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 additional dilution (the recommended dilution for TCI is 20 to 50 micrograms/mL).

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

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

Water for injectable preparations

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 packaging shows no deterioration. Discard any solution in which such defects are observed.

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 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 should be 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.
