This medicinal product must not be mixed with other medicinal products other than those mentioned in the section “Dilution instructions”.
Dilutions of Alfentanil Hameln should be prepared under controlled and validated aseptic conditions.
Alfentanil Hameln can be diluted with sodium chloride 0.9% solution, glucose 5% solution, glucose 5% + sodium chloride 0.9% solution or Ringer lactate to a concentration of 25‑80 micrograms / ml. Such solutions are compatible with infusion bags and plastic infusion sets.
Chemical and physical in-use stability has been demonstrated for 48 hours. From a microbiological point of view, the dilutions should be used immediately.
No special precautions apply when storing.
The product should be used immediately after opening the package.
If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2 to 8 ° C, unless dilution has taken place under controlled and validated aseptic conditions.

Dosage and route of administration
Method of administration
Alfentanil Hameln is administered intravenously as bolus injections (for short procedures) or bolus injections supplemented with additional doses or by infusion(for long painful procedures) and should only be given by healthcare professionals trained in anesthesia administration and management of the effects of potent opioids on the respiratory tract.
Dosage for adults
Alfentanil Hameln should be dosed individually taking into account age, body weight, physical status, underlying medical conditions, other medications, and type of surgery and anesthesia.
The initial dose should be reduced in elderly and weak patients. The effect of the initial dose should be taken into account in the calculation of additional doses.
To avoid bradycardia, a small intravenous dose of anticholinergic should be given just before induction. Postoperative nausea is usually relatively short-lived and can be easily controlled with conventional methods.
Dosage for children
Assistive ventilation equipment should be available for use in children of all ages, even during short interventions where children breathe spontaneously.
Information on use in children, in the age group 1 month to 1 year, is limited (see section 5.2 of the SPC).
Due to the large variation in how younger children respond to alfentanil, it is difficult to establish dosage recommendations for younger children. For older children, a bolus dose of 10 to 20 micrograms/kg alfentanil is considered suitable for induction of anesthesia (ie as an adjunct to propofol or inhalation anesthesia) or as an analgesic. Additional bolus doses of 5 to 10 micrograms/kg alfentanil may be given at appropriate intervals.
To maintain analgesia in children during surgery, Alfentanil Hameln Hameln can be given at an infusion rate between 0.5 to 2 micrograms/kg/min. Dose one must be titrated up or down according to the needs of the individual patient. When combined with an intravenous anesthetic, a dose rate of approximately 1 microgram/kg/min is recommended.
There may be a higher risk of respiratory complications and muscle rigidity when alfentanil is administered to newborns and very young children. Necessary precautions are described in section 4.4 of the Summary of Product Characteristics.
