What Naropin with Fentanyl is for

Naropin with Fentanyl is used after surgery to treat post-operative pain.

NAROPIN is a local anaesthetic (an-a-set-ik). When injected, it makes the nerves nearby unable to pass messages to the brain and will therefore prevent or relieve pain.

FENTANYL belongs to a group of medicines called narcotic analgesics. It is a powerful drug used to relieve pain. It works by changing the way your brain receives pain messages.

Naropin with Fentanyl is a combination of the two drugs and produces anaesthesia (loss of feeling) and analgesia (pain relief).

Your doctor will have explained why you are being treated with Naropin with Fentanyl and told you what dose you will be given.

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

Your doctor may prescribe this medicine for another use. Ask your doctor if you want more information.

As it contains fentanyl, Naropin with Fentanyl can be addictive, but when it is used only to relieve or prevent pain it is unlikely to become habit forming.

How Naropin with Fentanyl is given

Naropin with Fentanyl will be injected by your doctor into the epidural space, near your spinal cord, through a space between the bones in your lower back. A thin tube will be inserted so a dose can be given over a period of time.

This is called an epidural infusion and it will result in a feeling of numbness in your lower body, in an area that may seem unrelated to the injection.

Naropin with Fentanyl is not injected directly into the blood.

The dosage you will be given will depend on your body size, age and the type of pain relief required.

Your doctor will have had a lot of experience injecting Naropin with Fentanyl or other similar drugs and will choose the best dose for you. They will be willing to discuss this decision with you.


The doctor giving you Naropin with Fentanyl will be experienced in the use of this type of medicine, so it is unlikely that you will be given too much.

However, if you are particularly sensitive to Naropin with Fentanyl, or the dose is accidently injected directly into your blood, you may develop problems for a short time with your sight or hearing.

You may get a numb feeling in or around the mouth, feel dizzy or stiff, or have twitchy muscles.

In rare cases, these effects may be followed by drowsiness and fits. In extreme cases you may have problems with your breathing or your heart and you may become unconscious.

Whenever you are given Naropin with Fentanyl, equipment will be available to care for you if you are given too much.

While you are being given it

Things to be careful of

Be careful driving or operating machinery after you have been given Naropin with Fentanyl. You may be drowsy and your reflexes may be slow.

Do not stand up or walk unless somebody is there to help you. Naropin with fentanyl can make your legs numb and you might fall.

Do not drink alcohol while you are being given Naropin with Fentanyl. If you drink alcohol while you are being given Naropin with Fentanyl your blood pressure may drop making you feel dizzy and faint.

Please talk to your doctor or pharmacist about these possibilities if you think they may bother you.
