MEZOLAR MATRIX 12 MICROGRAMS / HOUR TRANSDERMAL PATCH - patient leaflet, side effects, dosage

What Mezolar Matrix is and what it is used for

The name of your medicine is Mezolar Matrix

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 medicines and who need continuous pain treatment.

Mezolar Matrix contains an active substance called fentanyl. It belongs to a group of strong painkillers called opioids.

What you need to know before you use Mezolar Matrix

Do not use Mezolar Matrix 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 Mezolar Matrix.

Warnings and precautions

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

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 Mezolar Matrix.

Side effects and Mezolar Matrix

• Mezolar Matrix 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 Mezolar Matrix 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 Mezolar Matrix, tell your doctor – this may increase the amount of medicine that passes through your skin
• Mezolar Matrix 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 Mezolar Matrix

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 Mezolar Matrix if you buy any medicines from your pharmacy.

Your doctor will know which medicines are safe to take with Mezolar Matrix. 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 Mezolar Matrix you need. In particular, tell your doctor or pharmacist if you are taking:

• Medicines for helping you sleep (such as temazepam, zaleplon, or zolpidem).

• Medicines for relaxing your muscles (such as cyclobenzaprine or diazepam).
• Some medicines used to treat depression called SSRIs or SNRIs (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, or venlafaxine). – see below for more information

Mezolar Matrix with antidepressants

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

Use with central nervous system depressants, including benzodiazepines alcohol and some narcotic medicines

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

Because of this, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor does prescribe Mezolar Matrix together with sedative medicines, the dose and duration of concomitant treatment should be limited by your doctor. Please 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.

Do not drink alcohol while using Mezolar Matrix 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 Mezolar Matrix.

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 using this medicine.

Mezolar Matrix should not be used during pregnancy unless you have discussed this with your doctor. Mezolar Matrix should not be used during childbirth as the medicine can affect the breathing of the newborn child. Do not use Mezolar Matrix if you are breastfeeding. You should not breastfeed for 3 days after removing your Mezolar Matrix patch. This is because the medicine may pass into breast milk.

Where to apply the patch Adults

• Apply the patch on a flat part of your upper body or arm (not over a joint).
• 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.
• 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
• Each patch is sealed in its own sachet
• Tear open the sachet at the notch
• Gently tear off the edge of the sachet completely
• 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
• Make sure that the patch will be covered by loose clothing and not stuck under a tight or elasticated band
• Carefully peel the first part 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
• 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
