1 What Durogesic DTrans is and what it is used for

The name of your medicine is Durogesic DTrans

The patches help relieve pain that is very bad and long-lasting:

• in adults who need continuous pain treatment
• in children above 2 years of age who are already using opioid

medication and who need continuous pain treatment.

Durogesic DTrans contains a medicine called fentanyl. It belongs to a group of strong painkillers called opioids.

2 What you need to know before you use Durogesic DTrans

Do not use Durogesic DTrans if:

• You are allergic to fentanyl or any of the other ingredients of this medicine (listed in section 6)
• You have pain which lasts only for a short period, such as sudden pain or pain after having an operation
• You have breathing difficulties, with slow or shallow breathing

Do not use this medicine if any of the above apply to you or your child. If you are not sure, talk to your doctor or pharmacist before using Durogesic DTrans.

Warnings and precautions

• Durogesic DTrans can have life-threatening side effects in people who are not already regularly using prescribed opioid medicines.
• Durogesic DTrans is a medicine that could be life-threatening to children, even if the patches have been used. Bear in mind that a sticky patch (unused or used) could be tempting to a child and if it sticks to a child’s skin or they put it in their mouth, the result may be fatal.

Patch sticking to another person

The patch should be used only on the skin of the person for whom it has been prescribed. There have been reports of patches accidentally sticking to a family member while in close physical contact or sharing the same bed as the person wearing the patch. A patch accidently sticking to another person (particularly a child) can cause the medicine in the patch to go through the skin of the other person and cause serious side effects such as breathing difficulties, with slow or shallow breathing which may be fatal. In case the patch sticks to the skin of another person, take the patch off right away and get medical attention.

Take special care with Durogesic DTrans

Talk to your doctor or pharmacist before using this medicine if any of the following apply to you – your doctor may need to check you more closely if:

• You have ever had problems with your lungs or breathing
• You have ever had problems with your heart, liver, kidneys, or low blood pressure
• You have ever had a brain tumour
• You have ever had persistent headaches or a head injury
• You are elderly – you may be more sensitive to the effects of this medicine.
• You have a condition called ‘myasthenia gravis’ in which muscles become weak and tire easily.
• You have ever abused or been dependent on alcohol, prescription medicines or illegal drugs.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before using Durogesic DTrans.

Side effects and Durogesic DTrans

• Durogesic DTrans may make you unusually drowsy, and make your breathing more slow or shallow. Very rarely these breathing problems can be life-threatening or even fatal, especially in people who have not used strong opioid painkillers (like Durogesic DTrans or morphine) before. If you, or your partner or carer, notice that the person wearing the patch is unusually drowsy, with slow or shallow breathing:

• – Take the patch off

• – Call a doctor, or go to your nearest hospital straight away

• – Keep the person moving and talking as much as possible

• If you get a fever while using Durogesic DTrans, tell your doctor – this may increase the amount of medicine that passes through your skin
• Durogesic DTrans may cause constipation, talk to your doctor or pharmacist for advice on how to prevent or relieve constipation.
• Repeated, long term use of the patches may make the medicine less effective (you become ‘tolerant’ to it) or you may become dependent on it.

See section 4 for a full list of possible side effects.

When you are wearing the patch do not expose it to direct heat such as heating pads , electric blankets, hot-water bottles, heated water beds or heat or tanning lamps. Do not sunbathe, have long hot baths or saunas or use hot whirlpool spa baths. If you do, you may increase the amount of medicine you get from the patch.

Other medicines and Durogesic DTrans

Tell your doctor or pharmacist if you are taking, have recently taken or might take 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 if you buy any medicines from your pharmacy.

Your doctor will know which medicines are safe to take with Durogesic DTrans. You may need to be closely monitored if you are taking some of the types of medicines listed below or if you stop taking some of the types of medicines listed below, as this may affect the strength of Durogesic DTrans you need.

Durogesic DTrans with antidepressants

The risk of side effects increases if you are taking medicines such as certain antidepressants.

Durogesic DTrans may interact with these medicines and you may experience changes to mental status such as feeling agitated, seeing, feeling, hearing, or smelling things that are not there (hallucinations) and other effects such as changing blood pressure, fast heart beat, high body temperature, overactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting and diarrhoea.

Use with Central Nervous System Depressants, including alcohol and some narcotic drugs

Tell your doctor if you are taking any other medicines that slow down your central nervous system (CNS depressants). CNS depressants are, for example, medicinal products that make you sleepy, reduce anxiety or decrease awareness (see also Other medicines and Durogesic DTrans); but also alcohol and some narcotic drugs are CNS depressants. Taking these kinds of medicines with Durogesic DTrans can cause severe drowsiness, decreased awareness, breathing difficulties with slow or shallow breathing, coma and death.

Do not drink alcohol while using Durogesic DTrans unless you have talked to your doctor first.

Operations

If you think that you are going to receive anaesthesia tell your doctor or dentist that you are using Durogesic DTrans.

Pregnancy and breastfeeding

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.

Durogesic DTrans should not be used during pregnancy unless you have discussed this with your doctor.

Durogesic DTrans should not be used during childbirth as the medication can affect the breathing of the newborn child.

Do not use Durogesic DTrans if you are breastfeeding. You should not breastfeed for 3 days after removing your Durogesic DTrans patch. This is because the medicine may pass into breast milk.

Driving and using machines

Durogesic DTrans can affect your ability to drive and use machines or tools as it may make you sleepy or dizzy. If this happens, do not drive or use any tools or machines.

• 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.

3 How to use Durogesic DTrans

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

Your doctor will decide which strength of Durogesic DTrans is most suitable for you, taking into account the severity of your pain, your general condition and type of pain treatment that you have received so far.

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 when to change your patch:

Where to apply the patch

Adults

• Apply the patch on a flat part of your upper body or arm (not over a joint).

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.
• Watch your child very closely for 48 hours after:

• – The first patch has been put on

• – A higher dose patch has been put on

• It may take some time for the patch to have its maximum effect. Therefore, your child might need to use other painkillers as well until the patches become effective. Your doctor will talk to you about this.

Adults and Children:

Do not apply the patch on

• The same place twice in a row.
• Areas that you move a lot (joints), skin that is irritated or with cuts.
• 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.

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 sachet

• Each patch is sealed in its own sachet
• Tear or cut open the sachet at the notch, shown by the arrow
• Gently tear or cut off the edge of the sachet completely (if you use scissors, cut close to the sealed edge of the sachet to avoid damaging the patch)
• Grasp both sides of the opened sachet and pull apart
• Take the patch out and use straight away
• Keep the empty sachet to dispose of the used patch later
• Use each patch once only
• Do not take the patch out of its sachet 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 a patch off, fold it firmly in half so that the sticky side sticks to itself
• Put it back in its original sachet and dispose of the sachet as instructed by your pharmacist
• Keep used patches out of sight and reach of children – even used patches contain some medicine which may harm children and may even be fatal

Step 5: Wash

• Always wash your hands after you have handled the patch using clean water only

How quickly will the patches work?

• It may take some time for your first patch to have its maximum effect.

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

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 additional painkillers (or both)
• If increasing the strength of the patch does not help, your doctor may decide to stop the use of the patches

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 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 you forget to change your patch

• If you forget, change your patch as soon as you remember and make 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 a patch falls off

• If a patch falls off before it needs changing, stick a new one on straight away and make note of the day and time. Use a new area of skin on: – Your upper body or arm

– Your child’s upper back
