at a starting dose greater than 25 micrograms/hour if you have never had opioid analgesics
for pain relief.
Do not use APO-Fentanyl if the packaging is torn or shows signs of tampering. Do not

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 APO-Fentanyl.
Tell your doctor if you (or a family member) have ever abused or been dependent on
alcohol, prescription medicines or illegal drugs.
Your doctor can advise you whether or not to use APO-Fentanyl or if you need to adjust
the dose or adapt your treatment.
APO-Fentanyl should not be used in children under 12 years of age of 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 APO-Fentanyl, 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). APO-Fentanyl should not be used in combination with these medicines.
APO-Fentanyl should be initiated 14 days after stopping treatment with MAOIs. Combination
of these medicines with APO-Fentanyl may increase the risk of serotonin syndrome,
a potentially life-threatening condition.
certain medicines used 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
(anaesthetics), muscle relaxants, allergy medicine that makes you drowsy, alcohol
or some illegal drugs). Combination of these medicines with APO-Fentanyl 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 APO-Fentanyl 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 used 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 and pharmacist can tell you what to do if you are taking any of these
Effect of alcohol
Avoid alcohol when using APO-Fentanyl since their combined effect may cause drowsiness.
As with all opioid analgesics, APO-Fentanyl may lead to tolerance with continued use.
Your doctor may, therefore, prescribe a higher dose of APO-Fentanyl after some time
to continue to give you pain relief.
HOW TO USE APO-FENTANYL
How to use the patch
APO-Fentanyl 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 at 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.
APO-Fentanyl 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 your 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. Open the pouch and remove the APO-Fentanyl patch. 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.
4. Remove the protective film. Avoid touching the adhesive side of the patch.
5. Apply the patch to the skin and press with the palm of the hand for about 30 seconds.
Make sure all of the patch is in contact with skin and the corners are stuck tightly.
6. Wash your 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 APO-Fentanyl correctly and remember when the next patch is due.
Your doctor may prescribed 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 APO-Fentanyl. 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 forgot 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
APO-Fentanyl 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 Accident and Emergency Department at the nearest hospital.
Do this even if there are no signs of discomfort or poisoning. The person may need
urgent medical attention.

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 APO-Fentanyl patch.

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, saunas or hot

an increase in the amount of fentanyl absorbed by the skin, resulting in possible
overdose and death.

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

Medicines like APO-Fentanyl can lead to addiction. This is unlikely when APO-Fentanyl
is used correctly.

may also occur in some people. Tell your doctor if you notice any other effects.
AFTER USING APO-FENTANYL
Keep APO-Fentanyl patches in the sealed pouch until it is time to apply them.
If you take it out of its original container it may not keep well.

metres (1.5 m) above the ground is a good place to store medicines.
Do not store APO-Fentanyl patches or any other medicine, in the bathroom or near a
sink. Do not leave medicines in the car or on window sills. Heat and dampness can
destroy some medicines.
