1. WHAT ALFENTANIL IS AND WHAT IT
IS USED FOR
Alfentanil belongs to a group of medicines called
opioid analgesics, which relieve or prevent pain.
Alfentanil is a strong painkiller which has a
very rapid effect. Alfentanil is used for surgical
procedures.
Alfentanil is used in adults for:
- Short procedures and outpatient surgery (day
case)
- Medium and long procedures when given as
an injection and followed by additional doses
or by continuous infusion
Alfentanil is used in neonates, infants and
children:
- for induction of anaesthesia
- as a pain killer during anaesthesia and for both
short and long surgical procedures
At very high doses, Alfentanil may be used
to induce unconsciousness (anaesthesia) in
patients with assisted breathing (artificially
ventilated patients).
2. WHAT YOU NEED TO KNOW BEFORE YOU
USE ALFENTANIL
Do not use Alfentanil if:
- you are allergic (hypersensitive) to Alfentanil,
other strong painkillers, or any of the other
ingredients (see list of ingredients in Section
6).
- you suffer from any illness causing
breathing difficulties and your breathing is
not assisted during and/or after surgery.
- you are taking any of the antidepressant
medicines known as monoamine oxidase
inhibitors (MAOIs) or have taken them
during the last two weeks.
Alfentanil should not be given during
labour or before the cord is clamped during
Caesarean section.
Warnings and precautions
Before you receive Alfentanil tell your doctor if
you have:
- a head injury - Alfentanil may influence the
clinical signs of patients with head injuries

- lung disease or other breathing difficulties
- a liver or kidney disorder
- a thyroid disorder
Other medicines and Alfentanil
Please tell your doctor or nurse if you are taking,
or have recently taken, any other medicines,
including medicines you can get without a
prescription. This is especially important with the
following medicines as they may interact with
your Alfentanil:
- fluconazole, ketoconazole (treatment of fungal
diseases)
- erythromycin (an antibiotic drug)
- diltiazem (treatment of high blood pressure or
angina)
- cimetidine (treatment of heartburn or ulcers)
- ritonavir (treatment of HIV-AIDS)
- barbiturates (sleeping tablets)
- tranquilizers (treatment of anxiety)
- opioids (strong painkillers)
- inhalation general anaesthetics
-
beta-blockers (treatment of high blood
pressure and irregular heart rhythms)
- drugs affecting liver blood flow or liver
enzymes (your doctor will know what these
are)
It may still be all right for you to be given
Alfentanil and your doctor will be able to decide
what is suitable for you.
Elderly
The initial dose of Alfentanil should be
appropriately reduced in elderly and debilitated
patients.
Pregnancy and breast-feeding
Alfentanil should not be given to pregnant
women unless medically justified. Alfentanil
should not be used during childbirth as it can
affect the baby’s breathing. Breast-feeding is not
recommended. Ask your doctor or pharmacist for
advice before taking any medicine.

not drive or operate machinery for the following
24 hours.

children.
In obese patients (more than 20% above ideal

weight.
Lower doses may be adequate, for example, in
geriatric patients or where anaesthesia is being
supplemented by other agents.
Patients with renal impairment: No dosage
adjustment is needed.
Patients with hepatic impairment: Dose should
be modified depending on the clinical response
and degree of hepatic impairment, however no

Dosage in adults
The dosage of Alfentanil 500 micrograms/
ml should be individualised according to
age, bodyweight, physical status, underlying
pathological condition, use of other drugs and
type of surgery and anaesthesia.
Dosage in children
The
wide
variability
in
response
to
alfentanil makes it difficult to provide dosing
recommendations for younger children. For
older children a bolus dose of 10 to 20 μg/
kg alfentanil for induction of anaesthesia
(i.e. to supplement propofol or inhalationm
anaesthesia) or as an analgesic is considered
appropriate. Supplemental boluses of 5 to 10 μg/
kg alfentanil at appropriate intervals can be
administered.
To maintain analgesia in children during surgery,
an Alfentanil 500 micrograms/ml infusion rate
of 0.5 to 2 μg/kg/min may be administered. The
dose must be titrated up or down according
to the needs of the individual patient. When
combined with an intravenous anaesthetic agent
the recommended dose is approximately 1 μg/
kg/min.
There may be a higher risk of respiratory
complications and muscle rigidity when alfentanil
is administered to neonates and very young
children.
Assisted ventilation equipment should be
available for use in children of all ages, even

To maintain analgesia in children during surgery,
an Alfentanil 500 micrograms/ml infusion rate
of 0.5 to 2 μg/kg/min may be administered. The
dose must be titrated up or down according
to the needs of the individual patient. When
combined with an intravenous anaesthetic agent
the recommended dose is approximately 1 μg/
kg/min.
There may be a higher risk of respiratory
complications and muscle rigidity when alfentanil
is administered to neonates and very young
children.
Assisted ventilation equipment should be
available for use in children of all ages, even

for short procedures in spontaneously breathing
children.
In obese patients (more than 20% above ideal
total body weight), the dosage of alfentanil
should be determined on the basis of lean body
weight.
Lower doses may be adequate, for example, in
geriatric patients or where anaesthesia is being
supplemented by other agents.
Patients with renal impairment: No dosage
adjustment is needed.
Patients with hepatic impairment: Dose should
be modified depending on the clinical response
and degree of hepatic impairment, however no
quantitative recommendations are available.
In patients with hypothyroidism the dosage
should be titrated with care and prolonged
monitoring may be required.
For more information regarding recommended
dose modifications please refer to the SPC.
