What ASPEN FENTANYL is used for
ASPEN FENTANYL is a powerful drug used to relieve pain and produce sleepiness.
It can be used as a premedication before an operation, or with a general anaesthetic during an operation. It can also be used after painful operations to reduce the pain that you feel.
ASPEN FENTANYL belongs to a group of medicines called opioid (narcotic) analgesics.
It works by changing the messages that are sent to the brain about pain.
Your doctor will have explained why you are being treated with ASPEN 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.
Ask your doctor if you want more information. Your doctor may prescribe this medicine for another use.
ASPEN FENTANYL can be addictive, but when it is used only to relieve or prevent pain it is unlikely to become habit forming.

Before you are given it
You must tell your doctor if:
- you have been given ASPEN FENTANYL before and had any problems with it.
- you have any allergies to any ingredients listed at the end of this leaflet, other opioid analgesics (strong pain killers) e.g. morphine or pethidine, or any other substances.
If you have an allergic reaction, you may get a skin rash, hay fever or an asthma attack.
- you have any of these medical conditions:
- problems with your breathing such as severe asthma, severe bronchitis or emphysema
- a history of fits or head injuries
- myasthenia gravis (muscle weakness)
- heart problems
- liver or kidney problems
- you are taking MAO (monoamine oxidase) Inhibitors or have taken them within the last 14 days (ask your pharmacist if you are unsure)
- safe use in children under two year of age has not been established
- history of drug dependence.
It may not be safe for you to be given ASPEN FENTANYL if you have any of these conditions.
Taking other medicines
Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription at the chemist, supermarket or health food shop. These medicines may affect the way ASPEN FENTANYL works.
Your doctor or pharmacist can tell you what to do if you are taking any other medicines.
If you have not told your doctor about any of these things, tell them before you are given any ASPEN FENTANYL.
How ASPEN FENTANYL is given
ASPEN FENTANYL will be given to you by injection by an experienced doctor and you will be under constant supervision.
The injection may be given into a vein or into a muscle. It may be given before, during or after surgery.
Your doctor will prescribe the correct dose based on factors such as your age, bodyweight, physical status and medical condition.
The doctor or nurse giving you ASPEN FENTANYL will be experienced in its use, so it is extremely unlikely that you will be given too much.
However, the first sign of overdosage is often muscle spasm, followed by a marked slowing of your breathing, accompanied by a bluish tinge on the skin. You will probably lose consciousness.
ASPEN FENTANYL doses should be carefully worked out, so problems with overdosage are unlikely. There are other drugs, e.g. naloxone or nalorphine, which can be used if needed to reverse the effects of too much ASPEN FENTANYL.
Tell your doctor or nurse as soon as possible if you do not feel well after you have been given ASPEN FENTANYL. This medicine helps most people suffering severe pain, but it may have unwanted side-effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor, nurse or pharmacist to answer any questions you may have.
After you have been given ASPEN FENTANYL you will probably feel light-headed, dizzy, sleepy and you may feel quite strange, especially if you are not lying down.
Tell your doctor or nurse if you notice any of the following side effects and they worry you.
ASPEN FENTANYL may cause slowing down of breathing or muscle spasm.
ASPEN FENTANYL sometimes causes:
- changes in blood pressure (higher or lower)
- nausea (feeling sick)
- blurred vision
- euphoria (exaggerated sense of well-being).
Tell your doctor if you notice anything else that is making you feel unwell. Some people may get other side effects after being given ASPEN FENTANYL.
After taking it
If you are storing ASPEN FENTANYL at home keep them in the original pack in a cool dry place where the temperature stays below 30°C.
Do not store it or any other medicine in the bathroom or near a sink. Heat and dampness can destroy some medicines.
Keep it where young children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
Do not leave it in the car on hot days.
Make sure that you return to your doctor or pharmacist any injections that have passed the use by (expiry) date marked on the pack, or if you have any left over when your doctor says you no longer need to be given ASPEN FENTANYL injections.
