1. What is Sufentanil Kalceks and what is it used for

Sufentanil Kalceks contains the active substance sufentanil. It belongs to a group of medicines called "opioid anesthetics". Sufentanil is used as a pain reliever during or after surgery or to reduce pain during childbirth. Sufentanil is used as an anesthetic during surgical procedures in ventilated patients.

Adults

Intravenously (into a vein):

• to prevent pain during the induction and maintenance of general anesthesia in combination with other anesthetic medicines;
• as a medicine for the induction and maintenance of general anesthesia during major surgical procedures.

Epidurally (into the spine):

• to prevent pain after surgery and after cesarean section;
• to treat pain during childbirth.

Children

Sufentanil administered intravenouslyis indicated as a pain reliever for use during the induction and/or maintenance of general anesthesia in children over 1 month of age. Sufentanil administered epidurallyis indicated for the treatment of postoperative pain after general surgery, thoracic surgery, or orthopedic surgery in children over 1 year of age.

2. Important information before using Sufentanil Kalceks

When not to use Sufentanil Kalceks

• if the patient is allergic to sufentanil or any of the other ingredients of this medicine (listed in section 6);
• if the patient has any disease that causes breathing difficulties (e.g. asthma or chronic bronchitis);
• if the patient has a liver enzyme disease called "acute hepatic porphyria";
• if the patient is taking any medicines used to treat depression, known as monoamine oxidase inhibitors (MAOI). MAOI treatment should be stopped 2 weeks before surgery (see "Sufentanil Kalceks and other medicines");
• if the patient is taking or has recently taken other strong painkillers (e.g. nalbuphine, buprenorphine, pentazocine) (see "Sufentanil Kalceks and other medicines").
• Intravenously
• if the patient is in labor or before the umbilical cord is clamped during a cesarean section.
• Epidurally
• if the patient has severe bleeding or shock;
• if the patient has a severe infection;
• if the patient has impaired wound healing;
• if the patient has an infection at the injection site;
• if the patient has changes in blood cell count or is being treated with anticoagulant medicines.

Warnings and precautions

Sufentanil Kalceks should only be administered by trained anesthesiologists in hospitals or other facilities equipped with ventilatory support and postoperative monitoring equipment. Before starting treatment with Sufentanil Kalceks, you should discuss it with your doctor or nurse if:

• the patient has abnormally slow gut movement;
• the patient has gallbladder or pancreas disease;
• the patient or any of their relatives have ever abused alcohol, prescription drugs, or narcotics ("addiction");
• the patient smokes;
• the patient has ever had mood problems (depression, anxiety, or personality disorder) or has been treated by a psychiatrist for other mental illnesses.

This medicine contains sufentanil, which is an opioid medicine. Repeated use of opioid painkillers can lead to the medicine becoming less effective (the patient becomes accustomed to it). This can also lead to dependence and abuse of the medicine, which can result in life-threatening overdose. If the patient is concerned about the possibility of becoming dependent on Sufentanil Kalceks, it is essential to consult a doctor. During treatment with Sufentanil Kalceks, you should consult a doctor if:

• the patient experiences pain or increased sensitivity to pain (hyperalgesia) that does not respond to a higher dose of the prescribed medicine.

During treatment with this medicine, as with all strong painkillers of this type, breathing rate may decrease. This can last until the recovery period or occur again during this time. Therefore, the patient's condition will be closely monitored after surgery. Sufentanil Kalceks may cause sleep-related breathing disorders, such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms of these disorders may include pauses in breathing during sleep, nighttime awakenings due to shortness of breath, difficulty staying asleep, or excessive daytime sleepiness. If these symptoms are observed, you should contact a doctor. The doctor may consider reducing the dose. This medicine will not be used in patients with myasthenia (a chronic muscle disease), as it may cause muscle stiffness after intravenous administration. Involuntary muscle contractions may occur. This medicine should be used with caution:

• in patients with lung, liver, kidney, or thyroid disease;
• in patients with increased intracranial pressure or head or brain injuries;
• in patients with decreased blood volume (administration of this medicine may cause low blood pressure and slow heart rate);
• in elderly and debilitated patients (the dose may need to be reduced). Close medical supervision may be required.

Newborns/Infants
Newborns, like other opioids, are sensitive to respiratory difficulties after sufentanil administration. Only limited data on sufentanil are available after intravenous administration in infants. Therefore, the doctor will carefully assess the benefits and risks before using this medicine in newborns and infants. Due to the risk of overdose or underdose, it is not recommended to use sufentanil intravenously in the neonatal period. Sufentanil should not be used epidurally in children under 1 year of age.

Sufentanil Kalceks and other medicines

Tell your doctor or nurse about all medicines you are taking or have recently taken, as well as any medicines you plan to take. It is especially important if you are taking or have recently taken any of the following medicines:

• strong painkillers, such as opioids (e.g. nalbuphine, buprenorphine, pentazocine) (see "When not to use Sufentanil Kalceks");
• medicines used to treat depression, known as monoamine oxidase inhibitors (MAOI). These medicines should not be taken within 2 weeks before Sufentanil Kalceks administration or at the same time as Sufentanil Kalceks (see "When not to use Sufentanil Kalceks").
• medicines used to treat depression, known as selective serotonin reuptake inhibitors (SSRI) and serotonin-norepinephrine reuptake inhibitors (SNRI). It is not recommended to use these medicines at the same time as Sufentanil Kalceks.
• sedatives and anxiolytics, such as barbiturates, sedatives, or benzodiazepines (e.g. diazepam, midazolam);
• muscle relaxants (e.g. vecuronium, suxamethonium);
• medicines used for general anesthesia (e.g. thiopental, etomidate, nitrous oxide);
• medicines used to treat mental disorders (antipsychotics);
• antibiotics used to treat bacterial infections (erythromycin);
• medicines used to treat fungal infections (e.g. ketoconazole, itraconazole);
• medicines used to treat viral infections (e.g. ritonavir used to treat HIV/AIDS).

Concomitant use of opioids and medicines used to treat epilepsy, nerve pain, or anxiety (gabapentin and pregabalin) increases the risk of opioid overdose and respiratory depression, which can be life-threatening. Concomitant use of Sufentanil Kalceks and sedatives, such as benzodiazepines or related medicines, increases the risk of sedation, breathing difficulties (respiratory depression), coma, and can be life-threatening. Therefore, their concomitant use should only be considered when other treatment options are not possible. If the doctor prescribes Sufentanil Kalceks with sedatives, the dose and duration of concomitant treatment should be determined by the doctor. You should inform the doctor about all sedatives you are taking and strictly follow the doctor's instructions for dosing. It may be helpful to inform friends or relatives to be aware of the signs and symptoms mentioned above. If such symptoms occur, you should contact a doctor.

Sufentanil Kalceks with alcohol

Alcohol may enhance some of the side effects of sufentanil. Therefore, you should not drink alcohol before and after using this medicine.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, ask your doctor or nurse for advice before using this medicine. Sufentanil Kalceks should not be administered intravenously during labor, as it crosses the placenta and may affect the baby's breathing. Sufentanil Kalceks may be administered epidurally during labor. Sufentanil passes into breast milk. Caution should be exercised when sufentanil is administered to a breastfeeding woman. Breastfeeding can be started 24 hours after the last use of sufentanil.

Driving and using machines

This medicine can have a major impact on your ability to drive and use machines. You should not drive or operate machinery until an appropriate amount of time has passed after receiving this medicine. You should leave the hospital with a companion and avoid drinking alcohol.

Sufentanil Kalceks contains sodium

The medicine contains 3.54 mg of sodium (the main component of common salt) per mL of solution. This corresponds to 0.18% of the maximum recommended daily intake of sodium in the diet for adults.

3. How to use Sufentanil Kalceks

Sufentanil Kalceks will be injected by a trained doctor into a vein (intravenously) or into the space surrounding the spinal cord (epidurally). During treatment with Sufentanil Kalceks, specially trained healthcare professionals will closely monitor the patient, and emergency equipment will be available if needed.

Dosage

The doctor will decide what dose and how long the patient (or child) will receive this medicine. The dose depends on age, weight, and physical condition, the type of surgical procedure, and the depth of anesthesia.

• The dose should be carefully adjusted in patients with hypothyroidism, impaired lung function, obesity, and alcoholism. After surgery, it is recommended to monitor these patients for a longer period.
• Patients with liver or kidney disease will require lower doses.
• Elderly and debilitated patients will require lower doses.

Use in children over 1 month and adolescents

Intravenous administration
Sufentanil is injected slowly into a vein by an anesthesiologist. The dosage depends on the dose of other anesthetics, the type and duration of the procedure, and will be determined by the anesthesiologist.

Use in children over 1 year and adolescents

Epidural administration
Sufentanil is injected slowly into the epidural space (part of the spine) by an anesthesiologist experienced in pediatric anesthesia techniques. The dosage depends on the concomitant use of local anesthetics and the required duration of analgesia. Children will be monitored for signs of abnormally slow and shallow breathing (respiratory depression) for at least 2 hours after epidural administration of sufentanil.

Using a higher dose of Sufentanil Kalceks than recommended

Since this medicine will usually be administered by a doctor in carefully controlled conditions, it is unlikely that too much of it will be given. However, if the patient accidentally receives too much sufentanil, breathing difficulties (weak or slow breathing or even temporary cessation of breathing) may occur. In this case, you should immediately inform the doctor or nurse. If you have any further questions about using this medicine, ask your doctor or pharmacist. The medicine should not be disposed of via wastewater or household waste. Ask your pharmacist how to dispose of medicines that are no longer needed. This will help protect the environment.
