WHAT FENTANYL IS AND WHAT IT IS USED FOR
Fentanyl contains the active ingredient fentanyl which is a strong pain-relieving medicine known as an
opioid. The Fentanyl unit comes as a lozenge on a stick.
• It is used to treat breakthrough pain in adult patients with cancer who are already taking other opioid pain
medicines for their persistent (around-the-clock) cancer pain. Breakthrough pain is additional sudden pain
that occurs suddenly in spite of your having taken your usual opioid pain-relieving medicines.
• Do not use Fentanyl if you have not been having a prescribed opioid medicine for persistent (around-theclock) pain regularly every day, for at least a week. This is because if you are not having such a medicine,
using Fentanyl may increase the chances of your breathing becoming dangerously slow or shallow, or even
• Do not use Fentanyl to treat pain from injuries, surgery, headaches or migraines.
BEFORE YOU USE FENTANYL
Do not use Fentanyl if
• You are allergic (hypersensitive) to fentanyl or any of the other ingredients of Fentanyl (listed in Section
• You are currently taking monoamine-oxidase inhibitor (MAOI) medicines for severe depression (or have
taken them in the past 2 weeks).
• You have severe breathing problems or severe lung problems where you have an obstruction.
Do not use Fentanyl if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist
before using Fentanyl.
Take special care with Fentanyl
Keep using the opioid pain medicine you take for your persistent (around-the-clock) cancer pain during your
Fentanyl is not recommended for children below 16 years of age.
If you have any of the following talk to your doctor or pharmacist before starting Fentanyl:
Your other opioid pain medicine for your persistent (around-the-clock) cancer pain is not stabilised yet.
You have any illness that affects your breathing (such as asthma, wheezing, or shortness of breath).
You have a head injury or have had any loss of consciousness.
You have a very, very slow heart rate.
You have liver or kidney problems - this will affect how your system breaks down the medicine.
You have low blood pressure due to a low amount of fluid in your circulation.
You have diabetes.
You are over 65 years old - you may need a lower dose and any dose increase will be reviewed very
carefully by your doctor.
Using other medicines
Do not use this medicine and tell your doctor or pharmacist if you are taking:
• Other fentanyl treatments that have been prescribed for your breakthrough pain in the past. If you still have
some of these fentanyl treatments at home, check with your pharmacist how to dispose of them.
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This
includes medicines obtained without a prescription, including herbal medicines. In particular, tell your doctor
or pharmacist if you are taking any of the following medicines:
• Any medicines which might make you sleepy - such as sleeping pills, medicines to treat anxiety, some
medicines for allergic reaction (antihistamines), or tranquillisers.
• Some muscle relaxants - such as baclofen, diazepam.
• Any medicines that might affect how your body breaks down Fentanyl - such as ritonavir or other
medicines that help control HIV infection, other so-called ‘CYP3A4 inhibitors’ such as ketoconazole,
itraconazole, or fluconazole (used for fungal infections) and troleandomycin, clarithromycin, or
erythromycin (medicines for bacterial infections) and so-called ‘CYP3A4 inducers’ such as rifampin or
rifabutin (medicines for bacterial infections), carbamazepine, phenobarbital or phenytoin, (medicines used
to treat convulsions/fits).
• Any medicine which may reduce or reverse the effect of Fentanyl – such as naloxone, pentazocine,
buprenorphine. These may lead to withdrawal symptoms.
• If you are due to have surgery requiring a general anaesthetic.
Using Fentanyl with food or drink
• Fentanyl may be used before or after meals. However do not use during meals.
• You may drink some water before using Fentanyl to help moisten your mouth. However, do not drink or
eat anything while using Fentanyl.
• Do not drink grapefruit juice while taking Fentanyl. This is because it may affect the way your body breaks
• Do not drink alcohol while using Fentanyl. It can increase the chances of getting dangerous side effects.
Pregnancy and breast-feeding
You should not use Fentanyl during pregnancy unless you have discussed this with your doctor. You should
not use Fentanyl during child-birth because fentanyl may cause breathing difficulties in the new-born child.
There is also a risk of the new-born child having withdrawal symptoms of the drug if Fentanyl is used for a
long time during pregnancy.
Fentanyl can get into breast milk and may cause side effects in the breast-fed infant. Do not use Fentanyl if
you are breast-feeding unless you have discussed this with your doctor. Breast-feeding should not be
restarted until at least 48 hours after the last use of Fentanyl.
Ask your doctor or pharmacist for advice before taking any medicine, if you are pregnant or breast-feeding.
Driving and using machines
This medicine may affect you being able to drive or use any tools or machines. Talk to your doctor about
whether it is safe for you to drive, or use any tools or machines in the first few hours after taking Fentanyl.
Do not drive or use any tools or machines if you: feel sleepy or dizzy; have blurred or double vision; have
difficulty in concentrating. It is important you know how you react to Fentanyl before driving or using any
tools or machines.
Important information about some of the ingredients of Fentanyl
• Fentanyl contains glucose and sucrose (types of sugar). If you have been told by your doctor that you
cannot tolerate or digest some sugars, talk to your doctor before using Fentanyl.
• Each lozenge contains about 2 grams of glucose. If you have diabetes, you need to take this into account.
• The glucose in the lozenge may be harmful to the teeth. Always make sure you clean your teeth regularly.
HOW TO USE FENTANYL
When you first start using Fentanyl, your doctor will work with you to find the dose that will relieve your
breakthrough pain. It is very important that you use Fentanyl exactly as the doctor tells you.
• Do not change doses of Fentanyl or your other pain medicines on your own. Change in dose must be
prescribed and checked by your doctor.
• If you are not sure about the right dose or if you have questions about taking this medicine, talk to your
How the medicine gets into your body
When you place the lozenge in your mouth:
• The lozenge dissolves and the active ingredient is released. It takes around 15 minutes for this to happen.
• The active ingredient is absorbed through the lining of your mouth, into the blood system.
Taking the medicine like this allows it to be absorbed quickly. This means that it relieves your breakthrough
While the right dose is being found
You should start to feel some relief quickly while you are taking Fentanyl. However, while you and the
doctor are finding out the dose that controls your breakthrough pain, you may not get enough pain relief
30 minutes after starting to use one Fentanyl unit (15 minutes from when you finish using the Fentanyl unit).
If this happens, your doctor may allow you to use a second Fentanyl unit of the same strength for that same
episode of breakthrough pain. Do not use a second unit unless your doctor tells you to. Never use more than
two units to treat a single episode of breakthrough pain.
While the right dose is being found, you may need to have more than one strength of Fentanyl units at home.
However, keep only the strengths of Fentanyl units you need in the house. This is to stop possible confusion
or overdose. Talk to your pharmacist about how to dispose of any Fentanyl units you do not need.
How many units to use
Once the right dose has been found with your doctor, use 1 unit for an episode of breakthrough pain.
Talk to your doctor if your right dose of Fentanyl does not relieve your breakthrough pain for several
episodes of breakthrough pain in a row. Your doctor will decide if your dose needs to be changed.
You must tell your doctor straight away if you are using Fentanyl more than four times per day. This is
because he may wish to change your medicine for your persistent (around-the-clock) pain. When he has done
this, when your persistent pain has been controlled, he may need to change your dose of Fentanyl. For the
most effective relief, tell your doctor about your pain and how Fentanyl is working for you. This is so that
the dose can be changed if needed.
How to use the medicine
Opening the pack – each Fentanyl unit is sealed in its own blister pack.
• Open the pack when you are ready to use it. Do not open it in advance.
• Hold the blister pack with the printed side away from you.
• Hold the short tab end of the blister pack.
• Put scissors close to the end of Fentanyl unit and cut the long tab end completely off (as shown).
• Separate the printed backing from the blister pack and pull the printed backing completely off the
• Remove the Fentanyl unit from the blister pack and put the lozenge in your mouth straight away.
Using the Fentanyl unit
• Put the lozenge between your cheek and gum.
• Using the handle, keep moving the lozenge round in your mouth, especially along your cheeks. Twirl
the handle often.
To get the most effective relief, finish the lozenge completely in 15 minutes. If you finish too quickly,
you will swallow more of the medicine and get less relief from your breakthrough pain.
• Do not bite, suck or chew the lozenge. This would mean lower blood levels and less pain relief than
when used as directed.
• If for some reason you are not finishing the whole lozenge each time you have breakthrough pain, talk
to your doctor.
How often you should use Fentanyl
Once a dose is found that effectively controls your pain, do not use more than four Fentanyl units each day.
If you think you might need to use more than four Fentanyl units per day, talk to your doctor straight away.
How many Fentanyl units you should use
Do not use more than two units to treat any single episode of breakthrough pain.
If you use more Fentanyl than you should
The most common side effects of using too much are feeling sleepy, sick or dizzy.
• If you begin to feel dizzy, sick, or very sleepy before the lozenge is completely dissolved, take it out of
your mouth and call another person in your house to help you.
A serious side effect of Fentanyl is slow and/or shallow breathing. This can occur if your dose of Fentanyl is
too high or if you take too much Fentanyl.
• If this happens, get medical help straight away.
What to do if a child or adult accidentally takes Fentanyl
If you think someone has accidentally taken Fentanyl, get medical help straight away. Try to keep the person
awake (by calling their name and shaking their arm or shoulder) until emergency help arrives.
If you forget to use Fentanyl
If you still have the breakthrough pain, you may use Fentanyl as your doctor has told you. If the
breakthrough pain has stopped, do not use Fentanyl until the next breakthrough pain episode.
If you stop using Fentanyl
Do not stop using Fentanyl without talking to your doctor. There are usually no noticeable effects if you
stop using Fentanyl. Keep taking your usual opioid medicine to treat your persistent (around-the-clock) pain
as instructed by your doctor.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
