WHAT REMIFENTANIL IS AND WHAT IT IS USED FOR

Remifentanil belongs to a group of medicines known as opioids used for pain relief. It differs from
other medicines in this group by its very quick onset and very short duration of action.
-

2.

Remifentanil may be used to stop you feeling pain before or while you are having an operation.
Remifentanil may be used to relieve pain while you are under controlled mechanical ventilation in
an Intensive Care Unit (for patients 18 years of age and over).

WHAT YOU NEED TO KNOW BEFORE YOU USE REMIFENTANIL

Do not use Remifentanil
- if you are allergic (hypersensitive) to remifentanil or any of the other ingredients of this
medicine (listed in Section 6)
- if you are allergic to fentanyl analogs
- as injection into the spinal canal
- as sole medicine to initiate anaesthesia.
If you are not sure if any of the above apply to you, talk to your doctor, nurse or pharmacist before
having Remifentanil.
Warnings and precautions

When do you need to be extra careful with this drug?
 if you suffer from impaired lung and/or liver function (you may be more sensitive for breathing
difficulties).

(you are then more susceptible to heart disorders).
Other medicines and Remifentanil

blockers.

HOW TO USE REMIFENTANIL

Remifentanil must only be given under carefully controlled conditions and emergency
equipment has to be available. Remifentanil will be given by or under the supervision of an
experienced doctor who is familiar with the use and action of the type of medicine.
You will never be expected to give yourself this medication. It will always be given to you by a person
who is qualified to do so.
Remifentanil must be given only by a single injection or as a continuous infusion into your vein. This
is where the drug is slowly given to you over a longer period of time.
The way you are given the drug and the dose you receive will depend on:

 how much pain you suffer from.
Dosage
The dosage varies from patient to patient. There are no dose adjustments needed for patients with
impaired kidney or liver function.
After your operation
Tell your doctor or nurse if you are in pain. If you are in pain after your procedure, they will be able to
give you other painkillers.
