1. what matrifen is and what it is used for

The name of your medicine is Matrifen.

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.

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

2. what you need to know before you use matrifen

Do not use Matrifen 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 Matrifen.

Warnings and precautions

Matrifen can have life-threatening side effects in people who are not already regularly using prescribed opioid medicines.
Matrifen 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 Matrifen

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 Matrifen.

Side effects and Matrifen

Matrifen 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 Matrifen 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 Matrifen tell your doctor -this may increase the amount of medicine that passes through your skin
Matrifen 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 Matrifen

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 Matrifen if you buy any medicines from your pharmacy.

Your doctor will know which medicines are safe to take with Matrifen. 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 Matrifen you need.

Matrifen with sedatives

Concomitant use of Matrifen and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However if your doctor does prescribe Matrifen together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor. Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.

Matrifen with antidepressants

The risk of side effects increases if you are taking medicines such as certain antidepressants. Matrifen 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 heartbeat, high body temperature, overactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting and diarrhoea.

Operations

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

Matrifen and alcohol

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

Matrifen can make you drowsy or breathe more slowly. Drinking alcohol may make these effects worse.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

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

Matrifen should not be used during childbirth as the medication can affect the breathing of the newborn child. Do not use Matrifen if you are breast-feeding. You should not breastfeed for 3 days after removing your Matrifen patch. This is because the medicine may pass into breast milk.

Driving and using machines

Matrifen 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 matrifen

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 Matrifen 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
