Using Matrifen with food and drink
Alcohol may increase the risk of breathing problems.
Pregnancy and breast-feeding
Safe use during pregnancy has not been established. Fentanyl should not be used during childbirth since fentanyl passes the placenta and may cause difficulties in breathing in the newborn child. Fentanyl is excreted into breast milk and may cause sedation and respiratory depression (reduced ability to breathe) in the breast-fed child. Breast-feeding should therefore be discontinued for at least 72 hours after removal of the patch. Do not use Matrifen if you are pregnant or breast-feeding unless your doctor has weighed the risks of not using to be greater than using Matrifen. Long-term treatment during pregnancy may cause withdrawal symptoms in the newborn child. If you get pregnant during treatment with Matrifen, consult your doctor.
Driving and using machines:
Fentanyl transdermal patch can make you drowsy; if this happens do not drive, use tools or machinery.

OWHAT MATRIFEN IS AND WHAT IT IS USED FOR
Matrifen belongs to a group of strong painkillers called opioids and acts through blocking the pain signals to the brain.
In Matrifen transdermal patch the active substance fentanyl is deposited. Fentanyl is gradually released from the patch, passes through the skin and into the body, where it relieves severe and long-lasting pain, which can only be relieved by opioids. One transdermal patch relieves pain for 72 hours (3 days).

Matrifen can have life-threatening side-effects in persons that are not using prescribed opioid drugs on a regular basis.
Always use Matrifen exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The dose is determined by your doctor, who will adjust it for you individually. Always follow your doctor's instructions. Do not discontinue treatment without consulting your doctor.

Where to apply Matrifen transdermal patch
Adults - Find a flat part of your upper body (trunk) or upper 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 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 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.
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
• Body parts that have been irradiated in connection with radiation therapy
• 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 7 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 applying the patch
• If you need to clean the skin, just use cold water
• Do not use soap or any other cleansers, creams, moisturisers, oils, powders or talc before applying the patch
• Do not stick the 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
• Always remove the old patch before applying a new one.
Step 4: Disposing of the Patch
• As soon as you take the patch off, fold the used patch firmly in half so that the sticky side sticks to itself
• Put the used patch in the original pouch and discard according to local requirements or hand in to your pharmacist
• Even used patches contain some medicine which may harm children, so keep your used patches out of the reach and sight of children.
Step 5: Wash
Wash your hands afterwards with clean water.
More about using Matrifen 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 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 use more Matrifen than you should
If you or someone you know has stuck on too many patches or the wrong strength patch, take the patches off and contact the doctor or the nearest hospital straight away. While waiting for the doctor, keep the person awake by talking to or shaking her/him now and then.
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 you forget to use or 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 contact your doctor because you might need extra painkillers, but do not apply an extra patch.
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:
• 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 stick 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
