6.Contents of the package and additional information

Safentil belongs to a group of medications known as anesthetics and analgesics. It is a potent analgesic used in hospitals. Safentil can be administered intravenously (into a vein) to prevent pain during the induction and maintenance of combined anesthesia or as an anesthetic for the induction and maintenance of anesthesia, as part of major surgery.

Safentil can also be administered epidurally (into the spinal column) to alleviate pain after an intervention or to treat pain during normal childbirth (vaginal delivery).

The doctor will decide if this medication is suitable for you.

The doctor may administer Safentil for other indications. Consult your doctor.

Use in children

Intravenous route: Safentil is used as an analgesic (pain reliever) to initiate and/or maintain general anesthesia (balanced general anesthesia) in children aged one month and above.

Epidural route: Safentil is used in children aged one year and above to treat pain after certain operations: abdominal surgery, thoracic surgery (heart and lung), or orthopedic surgery (arms, legs, and back).

Your doctor will perform the necessary investigations before administering this medication to you.

Do not administer Safentil:

• If you are allergic to sufentanil, other opioid compounds, or any of the other components of this medication (listed in section6),
• If you have difficulty expectorating secretions, previous respiratory problems caused by treatment with other medications or any disease for which it is important to avoid respiratory problems.
• In epidural injection form, if you have severe bleeding or shock, severe blood infection, or infection at the injection site. Do not administer Safentil in epidural injection form if you have wound healing problems, if you are receiving anticoagulant treatment, or if you have other medical conditions that contraindicate epidural treatment.
• In intravenous injection form during delivery or cesarean section before umbilical cord clamping, as it may cause respiratory problems in the newborn.

Warnings and precautions

Consult your doctor before Safentil is administered to you:

• You feel pain or increased pain sensitivity (hyperalgesia) that does not respond to a higher dose of the medication as prescribed by your doctor.
• For intravenous injection, if you experience increased intracranial pressure, uncontrolled low metabolism (hypothyroidism), respiratory diseases, reduced lung capacity, are an alcoholic, or have liver or kidney dysfunction, are an elderly person, or feel weakened.
• During epidural injection, if you experience respiratory dysfunction or reduced lung capacity, and if the fetus shows signs of oxygen deficiency (fetal distress).
• If you have myasthenia gravis (chronic muscle disease).
• If you are taking monoamine oxidase inhibitors (a medication for depression, see section "Other medications and Safentil").
• If you are using other opioid-type medications (for example, strong pain medications), or if you have previously consumed or suffered dependence on this type of substance.
• You have abnormally slow bowel movements.
• You have a gallbladder or pancreas disease.
• You or any member of your family has ever abused or had dependence on alcohol, prescription medications, or illicit drugs ("addiction").
• You are a smoker.
• You have ever had mood-related problems (depression, anxiety, or personality disorder) or have been treated by a psychiatrist for other mental illnesses.

This medication contains sufentanil, which is an opioid. Repeated use of opioid analgesics can make the medication less effective (the body becomes accustomed to them). It can also produce dependence and abuse, which can lead to a potentially fatal overdose. It is essential to consult your doctor if you are concerned about developing dependence on Safentil.

Sleep-related respiratory disorders

Safentil can cause sleep-related respiratory disorders such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). These symptoms may include pauses in breathing during sleep, nocturnal awakening due to difficulty breathing, difficulty maintaining sleep, or excessive daytime somnolence. If you or someone else observes these symptoms, contact your doctor. Your doctor may consider reducing the dose.

Children and adolescents

It should not be administered intravenously to neonates due to the risk of overdose or administering too small a dose of Safentil.

Epidural administration of Safentil is not indicated in children under 1 year.

Use of Safentil with other medications

Inform your doctor if you are using, have used recently, or may need to use any other medication.

Inform your doctor if you are taking any of the following medications:

• Somnifacients, sedatives, medications for mental disorders, or substances affecting the central nervous system (for example, alcohol) as they may further impair breathing. In this case, your doctor may consider reducing the dose of Safentil.
• Medications for treating fungal infections (for example, ketoconazole and itraconazole) and antiviral medications (for example, ritonavir), as these medications may inhibit the circulation of sufentanil. Your doctor may consider reducing the dose of Safentil.
• Medications for treating depression, known as monoamine oxidase inhibitors (MAOIs). These medications should not be taken in the 2 weeks prior to or concurrently with Safentil administration.
• Medications for treating depression known as selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs). It is not recommended to use these medications concurrently with Safentil.
• Strong analgesics affecting the central nervous system (CNS inhibitors), alcohol, and some illicit substances - if you are taking strong analgesics or other medications affecting the central nervous system (for example, somnifacients, tranquilizers, medications for mental disorders, alcohol, or some illicit substances/illicit drugs), inform your doctor as it may be necessary to reduce the dose of Safentil. If you take strong analgesics or other substances affecting the central nervous system after Safentil has been administered during surgery, it may also be necessary to reduce the dose of the analgesic or the substances affecting the central nervous system to reduce the risk of severe adverse effects such as difficulty breathing with slow or shallow breathing, intense somnolence, and decreased level of consciousness, coma, and death.
• The concurrent use of opioids and medications for treating epilepsy, neurological pain, or anxiety (gabapentin and pregabalin), as they increase the risk of opioid overdose and respiratory depression and may put the patient's life at risk.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or if you think you may be pregnant or plan to become pregnant, consult your doctor before this medication is administered to you.

Safentil should only be administered during pregnancy if the benefits outweigh the potential risks. Safentil can be administered epidurally during delivery.

Sufentanil is excreted in breast milk. Your doctor will assess whether you should breastfeed.

Driving and operating machinery

Sufentanil may cause side effects that could severely affect your ability to drive safely.

Safentil may affect your ability to drive and operate machinery. Do not drive or operate machinery until a sufficient amount of time has passed since Safentil administration. When you return home, you should be accompanied by a responsible adult, and it is recommended that you avoid drinking alcohol.

Safentil contains sodium

This medication contains 9 mg of sodium per ml of injectable solution. This is equivalent to 0.45% of the maximum daily recommended sodium intake in an adult diet.

The doctor will inform you about the dose to be administered and the frequency. If you have doubts, consult your doctor. Only the doctor can modify the dose.

The dose is adapted according to your age, weight, general condition, diseases, use of other medications, type of intervention, and need for analgesia.

Safentil can be administered intravenously (into a vein) to relieve body pain (or as anesthesia) during surgical interventions.

Safentil can also be administered epidurally (in the area of the spinal column) to relieve pain in some parts of the body, for example during childbirth or after an intervention.

Usually, a doctor or nurse will administer the injection.

For more instructions on how to administer Safentil (including administration in children), consult the section "The following information is intended exclusively for healthcare professionals" at the end of the prospectus.

If you believe you have been administered too much Safentil

Contact your doctor if you believe you have been administered too much Safentil and do not feel well.

If you are administered too much Safentil, you will notice an increase in the effect, especially in the form of respiratory problems. In these cases, your doctor will take the necessary measures, such as oxygen supply and assisted breathing, and will closely monitor your body temperature and the amount of fluid you take.

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

Like all medicines, this medicine may cause side effects, although not everyone will experience them.

This information is intended solely for healthcare professionals:

Dosage and administration

Adults

Anesthesia and combined analgesia:

• Analgesia: 0.5 - 5 micrograms/kg by IV
• Anesthesia: 25 - 50 micrograms/kg by IV

Epidural analgesia in postoperative pain treatment: 25 - 50 micrograms.

Analgesic complement in childbirth: 5 - 20 micrograms by epidural.

Intravenous administration

To avoid bradycardia, it is recommended to administer a small dose of anticholinergic intravenously just before induction.

Epidural administration

The correct placement of the needle or catheter in the epidural space must be checked before injecting Safentil.

Pediatric population

Intravenous administration

Newborns (≤1 month)

Due to the high variability of pharmacokinetic parameters in newborns, it is not possible to make a reliable recommendation for the dose.

Children > 1 month

At all doses, to avoid bradycardia, premedication with an anticholinergic (such as atropine) is recommended, unless contraindicated.

Anesthesia induction

Safentil can be administered as a slow bolus of 0.2-0.5micrograms/kg over 30 seconds or more in combination with an anesthetic induction agent. In major surgery (e.g. cardiac surgery), doses of up to 1 microgram/kg may be administered.

Maintenance of anesthesia in ventilated patients

Safentil can be administered as part of a combined anesthesia. The dose depends on the dose of concomitant anesthetic agents, the type and duration of the intervention. An initial dose of 0.3-2 micrograms/kg administered as a slow bolus over at least 30 seconds may be followed by additional boluses of 0.1-1 micrograms/kg as needed up to a maximum total dose of 5 micrograms/kg for cardiac surgery.

Epidural administration

Only an anesthesiologist familiar with pediatric epidural anesthesia and the management of opioid-induced respiratory depression should administer Safentil to children by epidural route. Equipment for resuscitation and opioid antagonists should be readily available.

After epidural administration of Safentil, pediatric patients should be monitored for signs of respiratory depression for at least 2 hours. The use of sufentanil administered by epidural route in pediatric patients has been documented in only a limited number of cases.

Children <1

The safety and efficacy of sufentanil in children under 1 year have not been established.

No data are available in neonates or infants under 3 months.

Children > 1 year:

A single intraoperative dose of 0.25-0.75 micrograms/kg of sufentanil administered as a bolus relieves pain for a period of 1 to 12 hours. The duration of effective analgesia depends on the surgical intervention and concomitant epidural administration of local anesthetics of the amide type.

Elderly patients (≥65 years) and debilitated patients

Like other opioids, elderly patients and debilitated patients require lower doses.

The planned total dose should be carefully adapted in patients with any of the following conditions:

Also in these patients, prolonged postoperative monitoring is recommended.

Patients on chronic opioid treatment or with a history of opioid abuse may require higher doses.

Special precautions for disposal and other manipulations

It can be mixed with isotonic sodium chloride solution for infusion, 5% glucose solution for infusion and Ringer-lactate solution for infusion.

Use gloves when opening the vial. Accidental skin exposure should be treated by rinsing the affected area with water. Avoid using soap, alcohol and other cleaning products that may cause chemical or physical damage to the skin.

Period of validity after opening:

After opening, the medicine should be used immediately.

Period of validity after dilution

Chemical and physical stability has been demonstrated during use for 24 hours below 25°C and at 2-8°C.

From a microbiological point of view, the dilutions should be used immediately. If not used immediately, the time and conditions of storage during use are the responsibility of the user and normally should not exceed 24 hours at 2-8°C, unless the dilution was prepared in controlled and validated aseptic conditions.
