1. What Opiodur is and what it is used for
Fentanyl is one of a group of strong painkillers called opioids.
The painkiller, fentanyl, slowly passes from the patch, through the skin and into the body.
Adults
Opiodur is used for treatment of severe and long-lasting pain that can only adequately be managed with
strong pain relievers (opioids).
Children
Long term management of severe chronic pain in children receiving opioid therapy from 2 years of age.
2. What you need to know before you use Opiodur
Do not use Opiodur:
-- if you are hypersensitive (allergic) to fentanyl or any of the other ingredients of the product
-- if you suffer from pain which lasts only for a short period e.g. after a surgical procedure
-- if your central nervous system is severely impaired, for instance by brain injury.
Warnings and precautions
WARNING:
Opiodur is a medical product that could be life-threatening to children.
This is also the case with used transdermal patches.
Bear in mind that the design of this medicinal product could be tempting to a child.
Opiodur can have life-threatening side effects in persons that are not using prescribed opioid
medicines on a regular basis.
Before starting to use Opiodur you should inform your doctor if you suffer from any of the below disorders,
because the risk of side effects is higher and/or your doctor may need to prescribe a lower dose of
fentanyl.
-- asthma, respiratory depression or any lung disease
-- low blood pressure or low blood volume
-- impaired liver function
-- impaired kidney function
-- if you have had a head injury, a brain tumour, signs of increased intracranial pressure (e.g. headache,
visual disturbances), changes in your state of consciousness or loss of consciousness or coma
-- slow irregular heartbeat (bradyarrhythmias)
-- myasthenia gravis (a disease causing tiredness and weakness of the muscles).
• If you develop a fever while wearing Opiodur, tell your doctor as this may affect the way the medicine
passes through your skin.
• Do not expose the patch to a direct heat source such as heating pads, hot water bottles, electric
blankets, heat lamps, saunas and hot whirlpool spa baths. These may affect the way the medicine
works.

It is allowed to stay outside in the sun, but you must protect the patch with some piece of clothing during
hot summer days.
Tolerance, physical or psychological dependence may develop if you use Opiodur for a longer period. Tell
your doctor if you have ever abused or been dependent on alcohol, prescription medicines or illegal drugs.
If you are an elderly patient your doctor will monitor you more carefully, because it may be necessary to
prescribe a lower dose.
The patches should be not be cut into smaller parts, because the quality, efficacy and safety of such
divided patches have not been demonstrated.
The use of fentanyl patches may lead to a positive doping test. The use of fentanyl patches as a doping
agent may be hazardous to the health.
Children
Opiodur should not be administered to children under 2 years of age because there is limited experience
of use in children under that age. An exception can be made if the doctor has expressly prescribed
Opiodur.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription.
In particular, tell your doctor or pharmacist if you are taking:
-- other medicines for pain, such as other opioid painkillers (buprenorphine, nalbuphine or pentazocine)
medicines for helping you sleep
-- medicines to help you calm down (tranquillisers) and medicines for mental conditions
-- anaesthetics, if you think you are going to have an anaesthetic, tell your doctor or dentist that you
are using Opiodur
-- medicines for relaxing your muscles
-- some medicines used to treat depression (MAOIs, e.g. moclobemide against depression or selegiline
against Parkinson’s disease). You should not use Opiodur within 14 days of stopping these medicines.
-- Nefazodone, a medicine used to treat depression
-- Cimetidine, a medicine used to treat gastrointestinal diseases
-- medicines used for treating allergies or travel sickness (antihistamines/antiemetics). Especially ones
that make you sleepy.
-- some antibiotics used to treat infection, such as erythromycin, clarithromycin or troleandomycin
-- some antibiotics used to treat fungal infection, such as itraconazole, ketoconazole, fluconazole or
voriconazole
-- medicines used to treat HIV infection, such as ritonavir or nelfinavir
-- medicines used to treat an irregular heart beat, such as amiodarone, diltiazem or verapamil
Your doctor will know which medicines are safe to take with Opiodur patches. You may need to be closely
monitored if you are taking some of the types of medicines listed above as this may increase or prolong
the therapeutic effects and side effects of Opiodur and thus may affect the strength of Opiodur you need.
Using Opiodur with food, drink and alcohol
You should not consume alcohol during fentanyl treatment. Alcohol may increase the risk of breathing
problems. Simultaneous use of Opiodur and alcoholic beverages increases the risk of severe adverse
reactions, and may cause breathing difficulties, a fall of blood pressure, profound sedation and coma.
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine.
There are no adequate data from the use of Opiodur in pregnant women. If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for
advice before taking this medicine.
Opiodur should not be used during childbirth as the medication can affect the breathing of the newborn
child. Do not use Opiodur during pregnancy unless clearly necessary. Fentanyl is excreted into the
breast-milk and may cause side effects in the breast-fed infant as sedation and respiratory depression.
Breastfeeding should therefore be discontinued during treatment and for at least 72 hours after removal
of the patch.
Driving and using machines
Opiodur may impair mental and/or physical ability required for the performance of potentially hazardous
tasks such as driving a car or operating machinery. This has to be expected especially at the beginning of
treatment, at any change of dosage as well as in connection with alcohol or tranquilizers. If you have been
using the same dose of Opiodur for a longer period of time, your doctor may decide that you are permitted
to drive and use dangerous machines. Do not drive or operate dangerous machines while using Opiodur,
unless your doctor has told you that such is permitted.
3. How to use Opiodur
Always use Opiodur exactly as your doctor has told you. Check with your doctor or pharmacist if you are
not sure.
Your doctor will decide which strength of Opiodur is most suitable for you. Your doctor will base the
judgement on: the severity of your pain, your general condition and the type of pain treatment that you
have received so far.
According to your reaction the strength of the patch or the number of patches may need to be adjusted.
The effect is reached within 24 hours after the first patch has been applied and its effects fall gradually
after the patch is removed. Do not discontinue treatment without consulting your doctor.

Your first patch will start to work slowly, this may take as long as one day, so your doctor may give you
extra painkillers until your fentanyl transdermal patch starts working completely. After this, Opiodur should
help to relieve pain continuously and you should be able to stop taking these extra painkillers. However
sometimes you may still need extra painkillers.
Using and changing the patches
• There is enough medicine in each patch to last 3 days (72 hours)
• You should change your patch every third day, unless your doctor has told you otherwise.
• Always remove the old patch before applying the new one.
• Always change your patch at the same time of day every 3 days (72 hours)
• Make a note of the day, date and time you apply a patch, to remind you when you need to change
your patch.
• The following table shows you which day of the week to change your patch.

Where to apply the patch
Adults
• Apply the patch on a flat part of your upper body or arm.
Children
• Always apply the patch to the upper back to make it difficult for your child to reach it or take it off.
• Every so often check that the patch remains stuck to the skin.
• It is important you child does not remove the patch and put it in their mouth as this could be lifethreatening or even fatal.
• It may take some time before the patch becomes fully effective. Therefore, your child might need
additional painkillers until the patches become effective. Your doctor will advise you on this if it is
needed.
• Children need to be monitored very closely for 48 hours after:
-- The first patch has been put on
-- A higher dose patch has been put on.
For you and your child, do not apply the patch on:
• The same place twice in a row
• Sensitive areas that you move a lot, cuts, spots or other skin blemishes.
• Skin that is very hairy, if there is a hair, do not shave it (shaving irritates the skin). Instead clip the hair
as close to the skin as possible.
You should allow several days to pass before you put a new patch on the same area of skin.
Putting a patch on
Step 1: Preparing the skin
• Make sure your skin is completely clean, dry and cool before you put the patch on.
• If you need to clean the skin, just use cold water.
• Do not use soap or any other cleansers, creams, moisturisers, oils or talc before applying the patch.
• Do not stick a patch on straight after a hot bath or shower.
Step 2: Open the pouch
• Each patch is sealed in its own pouch
• Tear or cut off the edge of the pouch completely (if you use scissors, cut close to the sealed edge of
the pouch to avoid damaging the patch)
• Grasp both sides of the opened pouch and pull apart
• Take the patch out and use it straight away
• Keep the empty pouch to dispose of the used patch later
• Use each patch once only
• Do not take the patch out of its pouch until you are ready to use it
• Inspect the patch for any damage
• Do not use the patch if it has been divided, cut or looks damaged
• Never divide or cut the patch
Step 3: Peel and press
• Make sure that the patch will be covered by loose clothing and not stuck under a tight or elasticated band.
• Carefully peel one half of the shiny plastic backing away from the centre of the patch. Try not to touch
the sticky side of the patch.
• Press this sticky part of the patch onto the skin.
• Remove the other part of the backing and press the whole patch onto the skin with the palm of your
hand.
• Hold for at least 30 seconds. Make sure it sticks well, especially the edges.

Step 4: Disposing of the Patch
• As soon as you take the patch off, fold it firmly in half so that the sticky side sticks to itself.
• Put it back in its original pouch and put the pouch in the bin with your household rubbish.
• Even used patches contain some medicine which may harm children, so keep your used patches out
of the sight and reach of children.
Step 5: Wash
Wash your hands afterwards with clean water.
More about using Opiodur patches
How quickly will the patches work?
• It may take up to a day before your first patch is working completely.
• Your doctor may give you extra painkillers for your first day or so.
• After this, the patch should help to relive pain continuously so that you can stop taking other
painkillers. However, your doctor may still prescribe extra painkillers from time to time.
If your forget to change the patch
• If you forget, change your patch, as soon as you remember and make a note of the day and time.
Change the patch again after 3 days (72 hours) as usual.
• If you are very late changing your patch, you should talk to your doctor because you might need extra
painkillers, but do not apply an extra patch.
If you use too many patches or the wrong strength patch
• If you have stuck on too many patches or the wrong strength patch, take the patches off and contact
a doctor or the nearest hospital straight away.
Signs of an overdose include trouble breathing or shallow breathing, tiredness, extreme sleepiness,
being unable to think clearly, walk or talk normally and feeling faint, dizzy or confused.
If the patch falls off
• If the patch falls off before it needs changing, stick a new one on straight away and make a note of
the day and time. Use a new area on:
-- Your upper body or arm
-- Your child’s upper back
• Leave another 3 days (72 hours) before changing the new patch as usual
• If your patch keeps falling off, talk to your doctor, nurse or pharmacist.
If a patch sticks to another person
• Only use the patch on the skin of the person who it is prescribed for.
• Make sure the patch does not get rubbed off and sticks to your partner, especially in bed.
• If a patch accidentally sticks to another person, take it off straight away and talk to your doctor.
If your pain gets worse
• If your pain gets worse while you are using these patches, your doctor may try a higher strength
patch, or give you extra painkillers (or both)
• If increasing the strength of the patch does not help, your doctor may stop the patches.
If you want to stop using the patches
• Talk to your doctor before you stop using these patches.
• If you have been using them for some time your body may have got used to them. Stopping suddenly
may make you feel unwell.
• If you stop using the patches, don’t start again without asking your doctor first. You might need a
different strength patch when you restart.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, Opiodur can cause side effects, although not everybody gets them.
Take the patch off and tell your doctor or go to your nearest hospital straight away if you notice or suspect
any of the following. You may need urgent medical treatment.
• Feeling unusually drowsy, breathing more slowly or weakly than expected. Very rarely these
breathing difficulties can be life threatening or even fatal especially in people who have not used
strong opioid painkillers before. If you notice any of the above, follow the guidance above and
keep moving as much as possible.
