1. What is SECUFEN 5 micrograms/ml, solution for injection EFG and what is it used for

SECUFEN contains the active substance sufentanil, which is a potent analgesic (pain reliever).

SECUFEN is used in general anesthesia, resuscitation, and regional anesthesia.

Adults

In regional anesthesia, SECUFEN (IV or epidural) is injected epidurally. This technique is used in painless childbirth, general surgery, or post-operative pain.

Children

• By intravenous route, SECUFEN solution for injection (IV or epidural) is indicated as an analgesic agent in the induction and/or maintenance of balanced general anesthesia in children over one month of age.
• By epidural route, SECUFEN solution for injection (IV or epidural) is indicated for the treatment of pain after general, thoracic, or orthopedic surgery in children over one year of age.

2. What you need to know before you are given SECUFEN 5 micrograms/ml, solution for injection EFG

Do not use SECUFEN:

• If you are allergic (hypersensitive) to sufentanil citrate or to morphine derivatives, or to any of the other ingredients of SECUFEN listed in section 6.
• If you are allergic to morphine-derived medications.
• In combination with:

• Certain opioid medications (nalbuphine, buprenorphine), naltrexone (a medication used for addiction or relapse prevention), or nalmefene (a medication used in certain cases of alcohol dependence) (see section "Other medications and SECUFEN").

• Epidural administration may be contraindicated in certain treatments, such as anticoagulant treatment (medications that decrease blood clotting), generalized or localized infection at the injection site, and/or significant bleeding (blood loss).

Consult your doctor or pharmacist if you have any doubts.

Warnings and precautions

Be careful with SECUFEN solution for injection (IV or epidural):

• As with other morphine-like analgesics (pain-relieving medications), the use of SECUFEN solution for injection (IV or epidural) may be accompanied by respiratory depression (acute respiratory failure) that can persist for some time after surgery.
• Consequently, you will be under medical supervision for a while after surgery.
• If you experience significant drowsiness or respiratory problems after surgery, inform your doctor or healthcare staff immediately.
• When SECUFEN solution for injection (IV or epidural) is used for prolonged sedation, you will receive respiratory assistance.
• Generally, this medication cannot be administered if you are consuming alcoholic beverages, medications containing alcohol, crizotinib or idelalisib (anticancer medications), or sodium oxybate (see section "Other medications and SECUFEN solution for injection").
• Tell your doctor if you or a family member has a history of mental illness (such as depression), alcoholism, or addiction, as the risk of sufentanil dependence may increase depending on the dose and duration of treatment.
• The use (even at therapeutic doses) can lead to physical dependence, as it can cause withdrawal effects and the reappearance of problems if the medication is abruptly stopped.
• Tell your doctor if you are pregnant, think you may be pregnant, or are breastfeeding (for more information, see the section "Pregnancy").
• Tell your doctor if you experience increased sensitivity to pain, despite taking increasing doses (hyperalgesia). Your doctor will decide whether you need to modify the dose or stop taking this medication.

Tell your anesthesiologist if you have:

• Low blood pressure, hypovolemia, or heart failure.
• Brain blood flow problems.
• Any chronic respiratory disease.
• Liver or kidney problems.
• Hormonal deficiency of the thyroid gland.

Consult your doctor if you have any doubts.

Children and adolescents

Due to the risk of overdose or underdose, the use of SECUFEN by intravenous route is not recommended during the neonatal period.

The use of SECUFEN by epidural route is not recommended in children under one year of age.

Other medications and SECUFEN

Tell your doctor or pharmacist if you are using or have recently used any other medications, including those purchased without a prescription, homeopathic products, herbal remedies, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of one of them.

This medication cannot be administeredin any casewith certain opioids (nalbuphine, buprenorphine), with naltrexone (medication used for addiction or relapse prevention), or with nalmefene (medication used in certain cases of alcohol dependence).

This medication generally cannot be administeredif you are consuming alcoholic beverages, medications containing alcohol, crizotinib or idelalisib (anticancer medications), or sodium oxybate (medication used to treat certain sleep disorders).

You must tell your doctor if you are taking:

Medications that contain:

• Erythromycin, clarithromycin, or telithromycin (antibiotics)
• Itraconazole, voriconazole, posaconazole, or ketoconazole (for treating infections caused by microscopic fungi)
• Nelfinavir or ritonavir (used in the treatment of HIV infection)

·Strong analgesics or sedative medications (e.g., medications used to treat sleep disorders, medications used to reduce anxiety, medications for mental disorders, some cough medications), as the dose of SECUFEN may need to be reduced.

Similarly, if you are given a strong analgesic or another sedative medication after receiving SECUFEN during surgery, it may be necessary to reduce the dose of the analgesic or sedative medication to reduce the risk of serious side effects, such as respiratory problems, slow or shallow breathing, intense drowsiness, and decreased consciousness, coma, or death.

·Medications used to treat depression, such as monoamine oxidase inhibitors (MAOIs). These medications should not be taken within two weeks prior to the administration of SECUFEN or at the same time.

·Medications used to treat depression, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). It is not recommended to take these medications at the same time as SECUFEN.

Tell your doctor or pharmacist if you are using or have recently used any other medication.

Using SECUFEN with food and drinks:

To administer this medication, you should avoid consuming alcoholic beverages (see section "Warnings and precautions").

Pregnancy and breastfeeding:

Tell your anesthesiologist if you are pregnant or breastfeeding.

SECUFEN should not be used during pregnancy unless strictly necessary.

When this medication is administered to women during pregnancy, there is a risk that the newborn may experience neonatal withdrawal syndrome and respiratory depression.

The administration of SECUFEN in breastfeeding women should be done with caution and with doses not exceeding 30 µg; it is recommended to wait 4 hours after the administration of sufentanil before breastfeeding. Breastfeeding is not recommended with higher doses.

Driving and using machines:

SECUFEN may decrease your alertness or ability to drive.

A reasonable time should pass (at least 24 hours) between the administration of this medication and the resumption of driving or using machines.

Always consult your doctor.

The concomitant use of SECUFEN and sedative medications such as benzodiazepines or related medications (which can relieve anxiety and convulsions, allow muscle relaxation, and promote sleep) increases the risk of drowsiness, breathing difficulties, depression, and coma, and is likely to cause death. Therefore, the concomitant use of these medications should only be considered in the absence of any other viable treatment option. However, if SECUFEN is prescribed simultaneously with benzodiazepines and/or related medications, your doctor should limit the dose and duration of these concomitant treatments. Inform your doctor about all medications you are taking and follow their dosing recommendations strictly. It may be helpful to inform your friends or family members to be aware of the signs and symptoms mentioned above. Contact your doctor if you notice these symptoms.

This information is intended solely for doctors or healthcare professionals

Special Warnings

At the beginning of treatment, this medication may induce muscle stiffness.

This stiffness can be avoided if the following measures are taken:

• The injection should be slow enough when using sufentanil in low doses
• The administration of muscle relaxants immediately before the administration of this medication prevents muscle stiffness

When used in obstetrics by intravenous route, sufentanil will be administered after clamping the umbilical cord to prevent any depressive effect on the neonate's respiration. However, intravenous use is contraindicated during labor or before clamping the umbilical cord.

Posology and Method of Administration

This medication will be administered exclusively by specialist doctors in anesthesia - resuscitation or emergency medicine, familiar with the use of anesthetics, or under their control, and who have the necessary anesthesia - resuscitation equipment.

Sufentanil is usually administered more frequently in combination with other agents: intravenous anesthetics, volatile anesthetics, benzodiazepines.

Information intended for the person in charge of administering SECUFENinjectable solution (IV or epidural route):

The dosage varies depending on the anesthesia technique, the patient's condition, and the modalities of ventilation control.

Depending on the different indications, the method of use, and the dosages are as follows:

Adults

Intravenous Route

Balanced general anesthesia:

Short or medium-duration interventions (one or two hours): 0.1 to 2 micrograms/kg for induction associated with a hypnotic and/or a volatile anesthetic agent and a muscle relaxant

Doses of 10 to 25 micrograms of sufentanil can be administered for anesthesia maintenance, depending on clinical signs of decreased analgesia and tolerance to the initial dose

Major surgical interventions (more than 2 hours): the total dose will be calculated based on an administration of 1 microgram/kg/hour, to be adapted according to the surgical intervention, the patient's condition, and the associated products. 75% of the total dose can be administered as a bolus for induction and maintenance can be ensured either by injections of 10 to 50 micrograms depending on clinical signs of decreased analgesia or by continuous perfusion. Sufentanil can be associated with a hypnotic and/or a volatile anesthetic agent and a muscle relaxant. In case of bradycardia, a dose (to be determined) of an anticholinergic agent (atropine) can be used.

Analgesic anesthesia (cardiovascular surgery):

A bolus dose of 8 to 20 micrograms/kg will be administered for induction in association with 100% oxygen and a muscle relaxant compatible with the patient's cardiovascular condition.

A supplementary bolus of 5 to 10 micrograms/kg should be administered before sternotomy. Maintenance should be ensured either by repeated doses of 25 to 50 micrograms administered depending on signs of decreased analgesia and patient tolerance to the initial bolus, or by continuous perfusion.

In comparison with other morphine derivatives used in these protocols, the doses of associated medications such as volatile anesthetics, benzodiazepines, should generally be reduced.

The average total dose administered in cardiovascular surgery is 12 to 30 micrograms/kg, with an average extubation period of 12 to 18 hours.

However, the dosage should be adjusted according to other anesthetic agents used, as well as individual variations and the extubation period.

Prolonged sedation in intensive care or resuscitation units for ventilated patients:

0.2 to 2 micrograms/kg/hour, depending on the degree of sedation required and the doses of products eventually associated.

Epidural Route

General surgery (thoracic, urologic, orthopedic):

Initial doses of 0.75 micrograms/kg, diluted in 10 ml, allow for analgesia of 4 to 8 hours. Supplementary bolus doses of 25 to 50 micrograms can be administered depending on signs of decreased analgesia.

Obstetrics:

Bolus doses of 15 to 20 micrograms diluted in a volume of 10 ml, associated with a local anesthetic such as bupivacaine (0.125%-0.25%). It is recommended not to exceed the total dose of 30 micrograms of sufentanil.

Post-cesarean analgesia:

Bolus doses of 25 micrograms diluted in a volume of 10 ml, associated with a local anesthetic such as bupivacaine (0.125%-0.25%). It is recommended not to exceed the total dose of 30 micrograms of sufentanil.

Post-operative analgesia:

Bolus doses of 0.75 micrograms/kg diluted in a volume of 10 ml, in a single dose or repeated depending on signs of decreased analgesia (25 to 50 micrograms), or in perfusion at a rate of 0.2 to 0.3 micrograms/kg/hour.

Special Populations

As with other opioids, a dose reduction is recommended in elderly, debilitated patients, or those with ASA class III/IV.

Pediatric Population

Intravenous Administration

Due to the great variability of pharmacokinetic parameters in neonates, no dosage recommendation can be given (see sections 4.4 and 5.2).

Children over one month

Regardless of the dose, premedication with an anticholinergic such as atropine is recommended, unless contraindicated.

Induction of Anesthesia

SECUFEN can be administered in a slow bolus over at least 30 seconds at a dose of 0.2 to 0.5 micrograms/kg, in combination with another anesthetic agent for induction. In the case of major surgery (e.g., cardiac surgery), doses of up to 1 microgram/kg can be administered.

Maintenance of Anesthesia in Ventilated Patients

In balanced general anesthesia, the dose depends on the dose of the associated anesthetic agents and the type and duration of the surgery. An initial dose of 0.3 to 2 micrograms/kg administered in a slow bolus over at least 30 seconds can be followed by additional bolus doses of 0.1 to 1 microgram/kg as needed, up to a total dose of 5 micrograms/kg during cardiac surgery.

Epidural Route

SECUFEN should only be administered epidurally to children by anesthetists specially trained in pediatric epidural anesthesia and in the management of the respiratory depressive effects of opiates. The necessary resuscitation equipment, including intubation equipment and antimorphinics, should be readily available.

After the epidural administration of SECUFEN in children, signs of respiratory depression should be monitored for at least 2 hours.

The use of SECUFEN by the epidural route in children has only been documented in a small number of cases.

Children under one year

The safety and efficacy of SECUFEN have not been established in children under one year (see sections 4.4 and 5.1).

The currently available data in children over 3 months are described in section 5.1, but no recommendations can be given.

No data are available for neonates and infants under 3 months.

Children over one year

A single bolus dose of 0.25 to 0.75 micrograms/kg administered during surgery provides an analgesic effect for 1 to 12 hours. The duration of the analgesic effect depends on the type of surgical intervention and the concomitant use of a local epidural anesthetic of the amide type.

METHOD OF USE

If necessary, SECUFEN, injectable solution (IV or epidural route), can be mixed with saline or glucose solutions. These dilutions are compatible with plastic bags for perfusion. The dilutions should be used within 24 hours of preparation.

Instructions for Opening the Ampoules

Protective gloves should be used when opening the ampoules.

1. Hold the ampoule between the index and thumb fingers, allowing the tip of the ampoule to protrude.

1. With the other hand, hold the top of the ampoule with the index finger against the neck of the ampoule and the thumb over the colored point, parallel to the colored ring(s).

1. Maintaining the thumb on the point, break the top of the ampoule with a sharp movement while firmly holding the body of the ampoule in the hand.
