1. WHAT REMIFENTANIL IS AND WHAT IT IS USED FOR
Remifentanil is an anaesthetic belonging to a group of medicines called opioids (substances that have a
morphine-like action in the body).
This medicinal product is used:
to help put you to sleep before an operation,
to keep you asleep and stop you feeling pain during an operation,
to stop you feeling pain while you receive treatment in an Intensive Care Unit.
2. BEFORE YOU ARE GIVEN REMIFENTANIL
You must not be given Remifentanil :
- if you are allergic (hypersensitive) to the remifentanil or any of the other ingredients,
- if you are allergic (hypersensitive) to any other opioid medicines, such as morphine,
- if it is used as the sole agent for induction of anaesthesia,
As glycine is present in the formulation, Remifentanil must not be given for epidural and intrathecal
use (injection into the area around the spine or into the spinal fluid).
Take special care with Remifentanil
Before you are given Remifentanil , tell your doctor if you:
have had any respiratory disorders (problems with your breathing),
have severe heart disorders (heart failure),
have been told your blood pressure is low (hypotension), have severe liver disorders (hepatic
feel weakened or suffer from a decrease in blood volume (hypovolaemia). Caution will also
be exercised if you are older.
While under treatment with Remifentanil :
As with other morphine derivatives, you may experience:
- respiratory disorders (too shallow or too slow breathing),
- muscular rigidity. This effect depends on the dose and the administration speed. For this
reason, when given as a single slow administration into your vein (slow bolus injection),
Remifentanil Mylan should not be given to you in less than 30 seconds.
- low blood pressure (hypotension) or slowdown of heart rate (bradycardia).
If it happens, your doctor will administer an appropriate and specific treatment. He/she will adjust the
dose you are being given and the administration speed.
Your doctor will make sure you have fully regained satisfactory general condition before allowing you
to leave the recovery room.
Remifentanil has a very rapid offset of action. No residual painkilling activity will be
present within 5 to 10 minutes after stopping the administration. During surgery known to be painful,
on waking or during use in an Intensive Care Unit, painkillers must be given before stopping the
Remifentanil administration. Sufficient time must be allowed to ensure that the longer acting painkillers
are effective. These painkillers must be chosen as a function of the type of surgery and the level of postoperative monitoring.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription.
This is because Remifentanil can work with other medicines to cause side effects.
In particular, tell your doctor or pharmacist if you are taking medicines for your heart or blood
pressure, such as beta-blockers or calcium channel blockers, or medicines to induce sleep, reduce
anxiety or relax muscles belonging to the group of agents called benzodiazepines.
Pregnancy and breast-feeding
Inform your doctor if you are pregnant or planning to get pregnant or breast-feeding.
This medicine should generally not be used during pregnancy, unless otherwise indicated by your
You must not breast-feed for the 24 hours following the administration of Remifentanil.

your doctor or pharmacist for advice before taking any medicine.

Do not drive or use machines following anaesthesia including this medicine until your doctor tells you
that you may start these activities again.
It is advisable that you are accompanied when you return home and that you avoid consuming

The following information is intended for medical or healthcare professionals only
Remifentanil 2 mg, powder for concentrate for solution for injection or infusion
Instructions for use and handling
This medicine must be reconstituted by addition of 2 ml of solution for injection to obtain a
reconstituted solution with a concentration of remifentanil of approximately 1 mg/ml. After
reconstitution the solution must not be administered as is, but must be diluted further.
For infusions performed in manually-controlled mode, Remifentanil may be diluted at concentrations
ranging from 20 to 250 micrograms/ml (the recommended dilution is of 50 micrograms/ml in adults
and 20 to 25 micrograms/ml in children aged 1 year or older).
For administration by Target Controlled-Infusion, the recommended Remifentanil dilution is of 20 to
The reconstitution and dilution of the Remifentanil solution may be performed with one of the
following solutions for injection:
water for injections,
glucose 50 mg/ml (5 %) solution,
glucose 50 mg/ml (5 %) and sodium chloride 9 mg/ml (0.9 %) solution,
sodium chloride 9 mg/ml (0.9 %) solution,
sodium chloride 4.5 mg/ml (0.45 %) solution.
The dilution is dependent upon the technical capability of the infusion device and the anticipated
requirements of the patient.
This medicine is compatible with lactated Ringer’s solution for injection and lactated Ringer’s and
glucose 50 mg/ml (5 %) solution for injection as well as with propofol when administered into a
running intravenous catheter.
Please refer to the Summary of Product Characteristics for information on the posology.
Depending on indications, dosage recommendations are given for adults and/or children (aged 1 to 12
years) and adjustment is proposed for special populations.
Treatment of overdosage
In view of its very short duration of action, the risk of undesirable effects due to an overdose is limited
to the few minutes following its administration (after stopping the treatment, the return to initial
condition requires at most 10 minutes).
In case of a confirmed or suspected overdose, the protocol to follow is the following:
- stop the administration of the medicine,
- ensure patency of the airway,
- start artificial ventilation with oxygen,
- and establish haemodynamic stability.
If the respiratory depression is associated with a muscular rigidity, the administration of a
neuromuscular blocking agent may be required to facilitate ventilation.
Maintenance of vascular filling, the administration of certain medicines (vasopressors) to rectify
hypotension and other vital function assistance measures may be useful.
In case of severe respiratory depression and muscular rigidity, a morphine antidote, such as naloxone
may be administered by intravenous route. The duration of respiratory depression secondary to an
overdose is unlikely to exceed the duration of the antidote.
Stability and storage conditions
Remifentanil is preservative free and intended for single use only. Discard any unused solution.
Medicines should not be disposed of via wastewater or household waste.
Remifentanil must be reconstituted or diluted only with the recommended solutions for injection.
It should not be reconstituted or mixed with lactated Ringer’s solution for injection or lactated
Ringer’s and glucose 50 mg/ml (5 %) solution for injection.
This medicine should not be mixed with propofol or placed in the same solution for infusion.
It is not recommended to infuse this medicine in the same intravenous line as that used for blood,
serum or plasma.
This medicine should not be mixed with other medicines before its administration.
