What is in this leaflet
This leaflet answers some common questions about DUROGESIC patches. It does not contain
all the available information. It does not take the place of talking to your doctor
All medicines have risks and benefits. Your doctor has weighed the risks of you using
DUROGESIC against the benefits this medicine is expected to have for you.
If you have any concerns about using DUROGESIC, ask your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
What DUROGESIC is used for
DUROGESIC is used to relieve chronic or long-lasting pain, which requires strong painkillers.
DUROGESIC patches contain a medicine called fentanyl. This strong pain reliever belongs
to a group of medicines known as opioid analgesics. Fentanyl relieves pain by blocking
the nerves that recognise pain messages from the body.
Each patch is applied onto the skin every three days (72 hours). The patch releases
a continuous amount of fentanyl that is absorbed through the skin in contact with
Your doctor may have prescribed DUROGESIC for another reason. Ask your doctor if
you have any questions about why this medicine has been prescribed for you.
DUROGESIC patches may be retrieved and abused by addicts. Please ensure that used
patches are concealed and disposed of carefully. Return unused patches to the pharmacy
(see Disposal at the end of this leaflet).
Keep used and unused patches where children cannot reach them.
Before you use DUROGESIC
When you must not use it
Do not use DUROGESIC
if you have an allergy to fentanyl or any of the ingredients. See Product Description
at the end of this leaflet for a list of ingredients.
for acute pain or pain following surgery
for mild or intermittent pain
at a starting dose greater than 25 micrograms/hour if you have never had opioid analgesics
for pain relief.
Do not use DUROGESIC if the packaging is torn or shows signs of tampering. Do not
use DUROGESIC beyond the expiry date (month and year) printed on the pack.
Before you start to use it
You must tell your doctor if you
are pregnant or planning to become pregnant
are breast feeding or wish to breastfeed
have or have ever had liver or kidney disease
have or have ever had lung disease
have or have ever had heart disorders
have or have ever had brain lesions or head injuries
have medical conditions which lower your resistance to diseases.
You must tell your doctor if you have not used any opioid analgesics in the past,
unless you are being treated for cancer pain. This is because you may be more likely
to experience some of the side effects.
If you have not told your doctor or pharmacist about any of the above, tell them before
you start using or are given DUROGESIC.
Tell your doctor if you (or a family member) have ever abused or been dependent on
alcohol, prescription medicines, or illegal drugs.
Your doctor will advise you whether or not to use DUROGESIC or if you need to adjust
the dose or adapt your treatment.
DUROGESIC should not be used in children under 12 years of age or in adolescents under
18 years of age who weigh less than 50 kg.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including medicines
you can buy without a prescription from a pharmacy, supermarket or health food shop.
In particular, tell your doctor or pharmacist if you are taking any of the following:
other strong analgesics used to manage pain such as opioids and general anaesthetics.
ritonavir and nelfinavir (used to treat AIDS). Do not take ritonavir or nelfinavir
while using DUROGESIC, unless you are closely monitored by your doctor.
if taking rifampicin, carbamazepine, phenobarbital or phenytoin, careful monitoring
by your doctor and dose adjustment may be required.
antidepressant medicines belonging to the class monoamine oxidase inhibitors (MAOIs),
selective serotonin re-uptake inhibitors (SSRIs), or serotonin norepinephrine re-uptake
inhibitors (SNRIs). DUROGESIC should not be used in combination with these medicines.
DUROGESIC should be initiated 14 days after stopping treatment with MAOIs. Combination
of these medicines with DUROGESIC may increase the risk of serotonin syndrome, a potentially
certain medicines to treat depression such as nefazodone
medicines that slow down your central nervous system (for example medicines that makes
you sleepy, reduce anxiety or decrease awareness, such as sedatives, hypnotics, sleeping
tablets, tranquillisers, strong pain killers (opioids), medicines used for surgery
(anesthetics), muscle relaxants, allergy medicine that makes you drowsy, alcohol or
some illegal drugs). Combination of these medicines with DUROGESIC may increase the
sedative effect of these drugs or slow down your ability to react, breathing difficulties
with slow or shallow breathing, coma and death. A change in dose by your doctor may
be required if DUROGESIC is used with these medicines.
medicines used to treat mental illness or psychotic conditions and to relieve severe
nausea and vomiting, such as phenothiazines.
certain antibiotics used to treat infections such as clarithromycin and troleandomycin.
certain medicines to treat fungal infections such as ketoconazole and itraconazole
certain medicines that act on the heart and blood vessels such as calcium-channel
blockers like verapamil and diltiazem.
certain medicines used to treat arrhythmias such as amiodarone.
Your doctor or pharmacist can tell you what to do if you are taking any of these
Effect of alcohol
Avoid alcohol when using DUROGESIC since their combined effect may cause drowsiness.
As with all opioid analgesics, DUROGESIC may lead to tolerance with continued use.
Your doctor may, therefore, prescribe a higher dose of DUROGESIC after some time to
continue to give you pain relief.
How to use the patch
DUROGESIC is available in five different sizes. Your doctor will decide which patch,
or combination of patches, is suitable to control your pain.
Each patch is applied onto the skin and lasts for three days (72 hours).
After three days, remove the patch and apply a new patch to the skin in a different
You should not use more than one patch at a time, unless your doctor authorises otherwise
(for example to obtain a dose that cannot be achieved with a single patch). The
old patch should be removed before the new patch is applied.
DUROGESIC should not be used in children under 12 years of age or in adolescents under
18 years of age who weigh less than 50 kg.
Using it for the first time
The first patch may take up to a day to take effect after it is applied onto the skin.
This is because fentanyl is slowly absorbed through the skin into the blood. Your
doctor may prescribe additional medicines to control the pain for the first day.
Applying the patch
1. Find an intact and hairless spot of skin on the upper part of your body or on your
upper arm. The skin should be healthy and undamaged. Do not place the patch onto
skin that is red, burnt or damaged.
2. Trim any excess hair with scissors. Do not shave the hair since this may affect the
skin. If you need to wash the skin before applying the patch, use clean water only.
Do not use soap, oils or lotions. The skin should be completely dry before applying
3. To open the pouch, locate the pre-cut notch indicated by the scissors. Make a small
cut and fold at the notch. Carefully tear the pouch along the edge and then fully
open the pouch by folding it open like a book.
4. Remove the DUROGESIC patch from the sealed pouch.
Do not apply the patch if it looks damaged in any way. Never cut or divide the patch.
Do not use a patch that has been divided, cut, or damaged in any way.
5. Each DUROGESIC patch has a clear plastic protective (release) liner that can be peeled
off in two pieces. After folding the patch in the middle, peel off each part of the
protective liner separately.
Avoid touching the adhesive side of the patch.
6. Apply the patch to the skin and press with the palm of the hand for about 30 seconds.
Make sure the entire patch is in contact with skin and the corners are stuck tightly.
7. Wash hands after applying or removing the patch.
You can now leave the patch on the skin for three days (72 hours). You may have a
bath, shower or swim.
Always write the date and time you applied the patch on the carton. It will help
you to use DUROGESIC correctly and remember when the next patch is due.
Your doctor may prescribe additional pain relievers to control occasional outbreaks
Changing the patch
1. After three days (72 hours), remove the patch.
2. Fold the used patch in half so that the adhesive side sticks to itself. Wrap the
folded patch and carefully dispose of it in the garbage.
3. Apply a new patch straight away to a different area of the skin, following the steps
under "Applying the patch."
If you do not understand the instructions provided with this medicine, ask your doctor
or pharmacist for help.
If your pain continues, see your doctor who may prescribe additional medicines to
help control the pain or change the dose of DUROGESIC. Your doctor may advise you
initially to change the patch every two days (48 hours) instead of every three days
(72 hours) to achieve adequate pain relief.
If you forget to use it
If you forget to apply a patch, and are not sure what to do, check with your doctor
If you have trouble remembering when to apply each patch, ask your pharmacist for
If you receive too much (overdose)
The most important sign of overdose is difficulty in breathing. If a person using
DUROGESIC has abnormally slow or weak breathing, remove the patch. Keep the person
awake by talking to them or gently shaking them every now and then.
Immediately telephone your doctor or the Poisons Information Centre for advice, or
go to the Emergency Department at your nearest hospital.
Do this even if there are no signs of discomfort or poisoning. The person may need
urgent medical attention.

While you are using DUROGESIC
Things you must do
Always follow your doctor's instructions carefully.
Tell your doctor if you become pregnant while using DUROGESIC.
If your pain continues or returns, see your doctor. You may need additional medicines
to control the pain or a change in the strength of the DUROGESIC patch.
Tell your doctor if you develop a fever. At high temperatures, the amount of fentanyl
absorbed by the skin increases. Your doctor may need to adjust your DUROGESIC dose.
If you are about to start taking a new medicine, tell your doctor and pharmacist that
you are using DUROGESIC.
Things you must not do
DO NOT expose the patch to direct heat from electric blankets, heat pads, heated water
beds, heat or tanning lamps, intensive sunbathing, hot water bottles, long hot baths,
saunas or hot spa baths while you are using DUROGESIC. Direct exposure to such heat
may cause an increase in the amount of fentanyl absorbed by the skin, resulting in
possible overdose and death.
Do not use DUROGESIC to treat any other complaint unless your doctor says so.
Do not give the patches to anyone else, even if their symptoms seem similar to yours.
Do not stop using DUROGESIC unless your doctor advises you to do so. If you have
been using DUROGESIC for a long period of time but stop using it suddenly without
your doctor's advice, you may experience withdrawal symptoms (such as nausea, vomiting,
diarrhoea, anxiety and shivering). Seek your doctor's advice if you experience these
Things to be careful of
If the patch accidentally adheres to another person (for example a family member sharing
the same bed), remove the patch and contact your doctor. Do this even if there are
no signs of discomfort or drowsiness.
DUROGESIC can affect your alertness and ability to drive and operate machinery. Do
not drive or operate machinery until you know how this medicine affects you.
Different brands of fentanyl patches may vary in size, shape, colour or adhesiveness.
DO NOT switch brands of fentanyl patches unless your doctor and pharmacist authorise
