(see section 6 overleaf). The medicine passes slowly into your body through
your skin.

Warning and precaution
• Durogesic DTrans is a medicinal product that could be life-threatening to
children, even if the patches have been used. Bear in mind that a sticky
patch could be tempting to a child and in some cases may lead to a fatal
outcome.
• Durogesic DTrans can have life-threatening side effects in persons who
are not using prescribed opioid medicines on a regular basis.
Patch sticking to another person
The patch should be used only on the skin of the person for whom it has
been prescribed. Cases have been reported where a patch was accidentally
stuck to a family member while in close physical contact or sharing the same
bed as the patch wearer. A patch sticking to another person (particularly a
child) may result in an overdose. In case the patch sticks to the skin of
another person, take the patch off immediately and seek medical attention.
See also section 3 below.
Take special care with Durogesic DTrans patches
• Like some other strong painkillers, Durogesic DTrans patches may make
you unusually drowsy, and breathe more slowly or weakly.
Very rarely these breathing difficulties can be life threatening or even
fatal in people who have not used strong morphine-related painkillers
(like Durogesic DTrans) or morphine before. If you, or your partner or carer,
notice that you or your child are breathing much more slowly or weakly
then:
- Take the patch off
- Call a doctor, or go to your nearest hospital, straight away
- Keep moving and talking as much as possible
• If you develop a fever while wearing Durogesic DTrans patches, tell your
doctor as this may affect the way the medicine passes through your
skin
• Don’t expose the patch to direct heat such as heating pads, electric
blankets, hot-water bottles, heated water beds, heat or tanning
lamps, intensive sun bathing, prolonged hot baths, saunas or hot whirlpool
spa baths. These may affect the way the medicine is absorbed through the
skin
• Check with your doctor or pharmacist before using this medicine if you
have ever had:
- Problems with your lungs or breathing
- Problems with your heart or blood pressure and blood volume, liver or
kidneys
- Brain tumours
- Persistent headaches or a head injury
Your doctor might need to check you more closely.
• If you are very ill, very thin or elderly, you may be more sensitive to the
effects of the patches
• If you suffer from a condition in which muscles become weak and tire
easily, known as myasthenia gravis, talk to your doctor or pharmacist
before using Durogesic DTrans patches
• Like many other strong painkillers, repeated use of the patches may make
you become tolerant to the medicine or become dependent on it
• Tell your doctor if you have ever abused or been dependent on alcohol,
prescription medicines or illegal drugs.
• Durogesic DTrans may cause constipation, talk to your doctor or
pharmacist for advice on how to prevent constipation.
If you are not sure if any of the above applies to you, talk to your doctor or
pharmacist before using Durogesic DTrans patches.
Other makes of patch
There are other makes of fentanyl transdermal patch available, but they are
not all the same. If your patch looks different from one you have used before
you should check with your doctor or pharmacist before using it.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken
any other medicines. This includes medicines that you buy without a
prescription or herbal medicines. You should also tell your pharmacist that
you are using Durogesic DTrans patches if you buy any medicines from
your pharmacy.
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
Page 1

Apply your
patch on

• Medicines to help you calm down (tranquillisers) and medicines for mental

conditions.
• Medicines for relaxing your muscles
• Some medicines used to treat depression (such as citalopram, duloxetine
escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine)
• Some medicines used to treat depression (called MAOIs) You should not
take Durogesic DTrans within 14 days of stopping these medicines.
• Nefazodone a medicine used to treat depression
• Some antihistamines (especially ones that make you sleepy)
• Some antibiotics used to treat infection, such as erythromycin,
clarithromycin or troleandomycin
• Medicines 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
• Rifampicin (for treatment of TB)
• Some medicines used to treat epilepsy (such as carbamazepine,
phenobarbital or phenytoin)
Your doctor will know which medicines are safe to take with Durogesic
DTrans patches. You may need to be closely monitored if you are taking
some of the types of medicines listed above or if you stop taking some of the
types of medicines listed above, as this may affect the strength of Durogesic
DTrans you need. If you are not sure if any of the above applies to you, talk
to your doctor or pharmacist before using Durogesic DTrans patches.
Operations or tests
If you think that you are going to have an anaesthetic, tell your doctor or
dentist that you are using Durogesic DTrans.
Using Durogesic DTrans patches and drinking alcohol
Do not drink alcohol unless you have talked to your doctor first.
Durogesic DTrans patches can make you drowsy or breathe more slowly.
Drinking alcohol may make these effects worse.
Pregnancy and breast-feeding
You must tell your doctor before using Durogesic DTrans patches if you are
pregnant, think you may be pregnant or might become pregnant. Durogesic
DTrans patches should not be used during childbirth as the medication can
affect the breathing of the newborn child.
Do not breast-feed whilst using Durogesic DTrans patches You should not
breast-feed for 3 days after removing your Durogesic DTrans patch. This is
because small amounts of the medicine may pass into breast milk.
Ask your doctor or pharmacist for advice before taking any medicine if you
are pregnant or breast-feeding.
Driving and using machines
Durogesic DTrans patches can make you drowsy. If this happens, do not
drive or use any tools or machines.
This medicine can affect your ability to drive as it may make you sleepy or
dizzy.
• Do not drive while taking this medicine until you know how it affects you.
• It is an offence to drive if this medicine affects your ability to drive.
• However, you would not be committing an offence if:
- The medicine has been prescribed to treat a medical or dental problem and
- You have taken it according to the instructions given by the prescriber or in
the information provided with the medicine and
- It was not affecting your ability to drive safely
Talk to your doctor or pharmacist if you are not sure whether it is safe for you
to drive while taking this medicine.

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 that your child does not remove the patch and put it in their
mouth as this could be life-threatening 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 should 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 or your child, do not apply the patch on:
• The same place twice in a row.
• Sensitive areas that you move a lot, skin with cuts, spots or other skin
blemishes
• Skin that is very hairy. If there is 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 dry, clean 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 open the pouch at the notch, shown by the arrow
• Gently 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)

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 differently
• Always remove the old patch before applying a new one
• Always change your patch at the same time of day every 3 days (72
hours)
• If you are using more than one patch, change all your patches at the same
time
• 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:
Page 2

Step 4: Disposing of the patch
• As soon as you take a 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 and
may be fatal, so keep your used patches out of the sight and reach of
children.










Grasp both sides of the opened pouch and pull apart
Take the patch out and use 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

Everyday activities while using the patches
• The patches are waterproof
• You can shower or bathe while wearing a patch, but do not scrub the patch
itself.
• If your doctor agrees, you can exercise or play sport while wearing the
patch
• You can also swim while wearing the patch, but:
- Don’t use hot whirlpool spa baths
- Don’t put a tight or elasticated band over the patch
• Don’t expose the patch to direct heat such as heating pads, hot-water
bottles, electric blankets, heated water beds, heat or tanning lamps,
intensive sun bathing, prolonged hot baths or saunas. These may affect
the way the medicine is absorbed through the skin.
If you have any further questions on the use of this product, ask your doctor
or pharmacist.

Step 5: Wash
• Wash your hands afterwards with clean water

Possible side effects

Like all medicines, Durogesic DTrans patches can cause side effects,
although not everybody gets them.

More about using Durogesic DTrans 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 the first day or so
• After this, the patch should help to relieve pain continuously so that you
can stop taking other painkillers. However, your doctor may still prescribe
extra painkillers from time to time.
If you forget to change your 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 some 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 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 a patch falls off
• If a 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 of skin 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 patches keep falling off, talk to your doctor, nurse or pharmacist
If a patch sticks to another person (See also section 2 above)
• Only use the patch on the skin of the person who it was prescribed for
• Make sure the patch does not get rubbed off and sticks to your partner or
child, especially while sharing a bed or in close contact
• If a patch accidentally sticks to another person, take it off straight away
and seek immediate medical attention.
How long will you use the patches for?
Durogesic DTrans patches are for long-term pain. Your doctor will be able to
tell you how long you can expect to use the patches.

How to use Durogesic DTrans patches

Always use this medicine exactly as your doctor has told you. You should
check with your doctor or pharmacist if you are not sure.

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

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

first. You might need a different patch strength when you restart.

need urgent medical treatment.

especially in people who have not used strong opioid painkillers (like

Warning and precaution
• Durogesic DTrans is a medicinal product that could be life-threatening to
children, even if the patches have been used. Bear in mind that a sticky
patch could be tempting to a child and in some cases may lead to a fatal
outcome.
• Durogesic DTrans can have life-threatening side effects in persons who
are not using prescribed opioid medicines on a regular basis.
Patch sticking to another person
The patch should be used only on the skin of the person for whom it has
been prescribed. Cases have been reported where a patch was accidentally
stuck to a family member while in close physical contact or sharing the same
bed as the patch wearer. A patch sticking to another person (particularly a
child) may result in an overdose. In case the patch sticks to the skin of
another person, take the patch off immediately and seek medical attention.
See also section 3 below.
Take special care with Durogesic patches
• Like some other strong painkillers, Durogesic patches may make
you unusually drowsy, and breathe more slowly or weakly.
Very rarely these breathing difficulties can be life threatening or even
fatal in people who have not used strong morphine-related painkillers
(like Durogesic) or morphine before. If you, or your partner or carer,
notice that you or your child are breathing much more slowly or weakly
then:
- Take the patch off
- Call a doctor, or go to your nearest hospital, straight away
- Keep moving and talking as much as possible
• If you develop a fever while wearing Durogesic patches, tell your
doctor as this may affect the way the medicine passes through your
skin
• Don’t expose the patch to direct heat such as heating pads, electric
blankets, hot-water bottles, heated water beds, heat or tanning
lamps, intensive sun bathing, prolonged hot baths, saunas or hot whirlpool
spa baths. These may affect the way the medicine is absorbed through the
skin
• Check with your doctor or pharmacist before using this medicine if you
have ever had:
- Problems with your lungs or breathing
- Problems with your heart or blood pressure and blood volume, liver or
kidneys
- Brain tumours
- Persistent headaches or a head injury
Your doctor might need to check you more closely.
• If you are very ill, very thin or elderly, you may be more sensitive to the
effects of the patches
• If you suffer from a condition in which muscles become weak and tire
easily, known as myasthenia gravis, talk to your doctor or pharmacist
before using Durogesic patches
• Like many other strong painkillers, repeated use of the patches may make
you become tolerant to the medicine or become dependent on it
• Tell your doctor if you have ever abused or been dependent on alcohol,
prescription medicines or illegal drugs.
• Durogesic DTrans may cause constipation, talk to your doctor or
pharmacist for advice on how to prevent constipation.
If you are not sure if any of the above applies to you, talk to your doctor or
pharmacist before using Durogesic patches.
Other makes of patch
There are other makes of fentanyl transdermal patch available, but they are
not all the same. If your patch looks different from one you have used before
you should check with your doctor or pharmacist before using it.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken
any other medicines. This includes medicines that you buy without a
prescription or herbal medicines. You should also tell your pharmacist that
you are using Durogesic patches if you buy any medicines from your
pharmacy.
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

Your doctor will know which medicines are safe to take with Durogesic

types of medicines listed above or if you stop taking some of the types of
medicines listed above, as this may affect the strength of Durogesic you
need. If you are not sure if any of the above applies to you, talk to your
doctor or pharmacist before using Durogesic patches.
Operations or tests
If you think that you are going to have an anaesthetic, tell your doctor or
dentist that you are using Durogesic patches.
Using Durogesic patches and drinking alcohol
Do not drink alcohol unless you have talked to your doctor first.
Durogesic patches can make you drowsy or breathe more slowly. Drinking
alcohol may make these effects worse.
Pregnancy and breast-feeding
You must tell your doctor before using Durogesic patches if you are pregnant,
think you may be pregnant or might become pregnant. Durogesic patches
should not be used during childbirth as the medication can affect the
breathing of the newborn child.
Do not breast-feed whilst using Durogesic patches You should not
breast-feed for 3 days after removing your Durogesic patch. This is because
small amounts of the medicine may pass into breast milk.
Ask your doctor or pharmacist for advice before taking any medicine if you
are pregnant or breast-feeding.
Driving and using machines
Durogesic DTrans patches can make you drowsy. If this happens, do not
drive or use any tools or machines.
This medicine can affect your ability to drive as it may make you sleepy or
dizzy.
• Do not drive while taking this medicine until you know how it affects you.
• It is an offence to drive if this medicine affects your ability to drive.
• However, you would not be committing an offence if:
- The medicine has been prescribed to treat a medical or dental problem and
- You have taken it according to the instructions given by the prescriber or in
the information provided with the medicine and
- It was not affecting your ability to drive safely
Talk to your doctor or pharmacist if you are not sure whether it is safe for you
to drive while taking this medicine.

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 that your child does not remove the patch and put it in their
mouth as this could be life-threatening 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 should 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 or your child, do not apply the patch on:
• The same place twice in a row.
• Sensitive areas that you move a lot, skin with cuts, spots or other skin
blemishes
• Skin that is very hairy. If there is 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 dry, clean 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 open the pouch at the notch, shown by the arrow
• Gently 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)





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

If you have any further questions on the use of this product, ask your doctor
or pharmacist.

Step 5: Wash
• Wash your hands afterwards with clean water

Like all medicines, Durogesic patches can cause side effects, although not
everybody gets them.

More about using Durogesic 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 the first day or so
• After this, the patch should help to relieve pain continuously so that you
can stop taking other painkillers. However, your doctor may still prescribe
extra painkillers from time to time.
If you forget to change your 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 some 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 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 a patch falls off
• If a 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 of skin 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 patches keep falling off, talk to your doctor, nurse or pharmacist
If a patch sticks to another person (See also section 2 above)
• Only use the patch on the skin of the person who it was prescribed for
• Make sure the patch does not get rubbed off and sticks to your partner or
child, especially while sharing a bed or in close contact
• If a patch accidentally sticks to another person, take it off straight away
and talk to a 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.
Grasp both sides of the opened pouch and pull apart
Take the patch out and use 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



You can also swim while wearing the patch, but:
- Don’t use hot whirlpool spa baths
- Don’t put a tight or elasticated band over the patch
Don’t expose the patch to direct heat such as heating pads, hot-water
bottles, electric blankets, heated water beds, heat or tanning lamps,
intensive sun bathing, prolonged hot baths or saunas. These may affect
the way the medicine is absorbed through the skin.

Step 4: Disposing of the patch
• As soon as you take a 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 and
may be fatal, soo keep your used patches out of the sight and reach of
children.

How long will you use the patches for?
Durogesic patches are for long-term pain. Your doctor will be able to tell you
how long you can expect to use 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 patch strength when you restart.
Everyday activities while using the patches
• The patches are waterproof
• You can shower or bathe while wearing a patch, but do not scrub the patch
itself.
• If your doctor agrees, you can exercise or play sport while wearing the
patch
