What this medicine is used for
The name of your medicine is Remifentanil APOTEX powder for injection. It contains
the active ingredient remifentanil (as hydrochloride).
Remifentanil is an anaesthetic used with other anaesthetic medicines, to produce and/or
maintain heavy sleep during your operation. If you are a cardiac patient, it may also
be used to help relieve any pain immediately following your operation.
Remifentanil may also be used for patients in the Intensive Care Unit to maintain
sedation and relieve pain.
Ask your doctor if you have any questions about why this medicine has been prescribed
for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Remifentanil belongs to a group of medicines called opioids. It differs from other
medicines in this group by its very quick onset and very short duration of action.
As with other opioids, remifentanil can be addictive. This is unlikely to happen when
remifentanil is only used during your operation.
Use in children
This medicine should not be used in children less than 1 year old.

You should not receive this medicine if you are hypersensitive to, or have had an
allergic reaction to, other pain-relieving medicines which are similar to fentanyl

or difficulty breathing; swelling of the face, lips, tongue, throat or other parts

1. You have had any adverse reactions during an operation.
2. You have had any type of allergic reaction to opioid medicines (e.g. morphine, fentanyl,
pethidine, codeine) or to any medicines used during an operation.

your doctor will discuss the possible risks and benefits of being given this medicine
