Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Remifentanil-AFT. It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you being given Remifentanil-AFT against the benefits this medicine is expected to have for you.

If you have any concerns about being given this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Remifentanil-AFT is used for

Remifentanil-AFT 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 after your operation.

Remifentanil-AFT may also be used for patients in the Intensive Care unit to maintain sedation and relieve pain.

Remifentanil-AFT 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.

Your doctor may have prescribed Remifentail-AFT for another reason. Ask your doctor if you have any questions about why Remifentanil-AFT has been prescribed for you.

Remifentanil-AFT can be addictive but this is unlikely to happen when it is only used during your operation.
