1. What is Matrifen and what is it used for

The name of this medicine is Matrifen.
Matrifen is indicated for the treatment of chronic pain:

• in adults who require continuous treatment with painkillers
• in children over 2 years of age who have already used opioid medications and require continuous treatment with painkillers.

Matrifen contains the active substance fentanyl, which is a strong painkiller belonging to the opioid group.

2. Important information before using Matrifen

When not to use Matrifen

• if the patient is allergic to the active substance or any of the other ingredients of this medicine (listed in section 6),
• in case of acute, sudden, or post-operative pain,
• if the patient has severe respiratory depression (significant slowing and shallowing of breathing).

Do not use this medicine if any of the above situations apply to the patient. In case of doubts, consult a doctor or pharmacist before using Matrifen.

Warnings and precautions

• Matrifen may cause life-threatening side effects in people who do not regularly use opioid painkillers.
• Matrifen is a medicine that can be life-threatening to children. This also applies to used patches. It should be taken into account that the appearance of the patch (used or unused) may encourage a child to touch it, stick it to their body, put it in their mouth, etc., which can lead to death.
• The medicine should be stored in a safe and protected place, inaccessible to other people - see section 5 for more information.

In case of accidental attachment of the Matrifen patch to another person's skin

Patches should only be applied to the skin of the person they have been prescribed for.
There have been several reports of accidental attachment of a patch to another person's skin during close physical contact or while sleeping in the same bed with the person using the patches.
Accidental attachment of a patch to another person's skin (especially a child) can cause the medicine to be absorbed through the skin and cause severe side effects such as respiratory depression with slow and shallow breathing, which can be life-threatening.
If such a situation occurs, the patch should be removed immediately and a doctor should be consulted.

Special caution is required when using Matrifen

Beforeusing this medicine, the patient should talk to their doctor or pharmacistif they have any of the following conditions:

• the patient has had lung disease or breathing difficulties,
• the patient has had heart, liver, kidney problems, or low blood pressure,
• the patient has had a brain tumor,
• the patient has had headaches or head injuries,
• the patient is elderly - they may be more sensitive to the effects of this medicine,
• the patient has myasthenia gravis, a condition characterized by muscle weakness and fatigue

If any of the above conditions apply to the patient (or the patient is unsure), they should talk to their doctor or pharmacist before using Matrifen.

During patch use, the patient should inform their doctor if they experience breathing problems during sleep.

Opioids, such as Matrifen, can cause breathing problems during sleep, such as sleep apnea (pauses in breathing during sleep) and sleep hypoxia (low oxygen levels in the blood). The patient should inform their doctor if they, their partner, or caregiver notice any of the following symptoms:

• pauses in breathing during sleep
• nighttime awakenings due to shortness of breath
• difficulty staying asleep
• excessive daytime sleepiness. The doctor may decide to change the dose of the medicine.

During patch use, the patient should inform their doctor if they notice a change in their pain.

• the pain no longer subsides after applying the patch
• the pain worsens
• there is a change in the way the pain is perceived (e.g., the patient feels pain in a different part of the body)
• pain occurs when touched, which should not be the case. The patient should not change the dose on their own. The doctor may decide to change the dose or treatment.

Side effects of Matrifen

• Matrifen may cause unnatural fatigue, as well as slow and shallow breathing. Very rarely, these breathing problems can be life-threatening or lead to death, especially in people who have not previously used opioid painkillers (such as Matrifen or morphine). If the patient, partner, or caregiver notices that the person using the patches is excessively sleepy and has slow or shallow breathing, they should:
• remove the patch
• call a doctor or go to the nearest hospital immediately
• encourage the patient to move and talk as much as possible.
• If the patient develops a fever while using Matrifen, they should talk to their doctor - an increase in body temperature can significantly increase the absorption of the medicine through the skin.
• Matrifen may cause constipation; the patient should talk to their doctor or pharmacist about how to prevent or alleviate constipation.

For a full list of side effects, see section 4.
Do not heat the patch application site with external heat sources, such as heated pads, electric blankets, hot water bottles, heated beds, heat lamps, or tanning lamps. Do not sunbathe or use prolonged warming baths, saunas, or whirlpool baths. In these situations, there is a risk of increased release of the medicine from the patch.

Long-term use and tolerance

This medicine contains fentanyl, which is an opioid painkiller. Repeated use of opioid painkillers can lead to decreased effectiveness of the medicine (the patient becomes accustomed to it, known as tolerance) and increased sensitivity to pain (known as hyperalgesia). During Matrifen use, the patient's sensitivity to pain may also increase. Increasing the patch dose may temporarily reduce the pain, but it can also be harmful. If the patient notices a decrease in the effectiveness of the medicine, they should talk to their doctor. The doctor will decide whether to increase the dose or gradually reduce the use of Matrifen.

Dependence and addictive use

This medicine contains fentanyl, which is an opioid. It can cause dependence and (or) addiction.
Repeated use of Matrifen can also lead to dependence, abuse, and addictive use, which can result in life-threatening overdose. The risk of these side effects may increase with increasing dose and duration of use. Dependence or addictive use can cause the patient to feel a loss of control over the amount of medicine they use or how often they take it. The patient may feel the need to continue using the medicine, even if it no longer helps alleviate their pain.

• The patient or someone in their family has previously abused or been dependent on alcohol, prescription drugs, or illegal substances (addiction);
• The patient smokes tobacco;
• The patient has previously experienced mood disorders (depression, anxiety disorders, or personality disorders) or has been treated by a psychiatrist for other mental illnesses.

If the patient experiences any of the following symptoms while using Matrifen, it may indicate dependence or addictive use.

• The patient needs to take the medicine for a longer period than prescribed by the doctor.
• The patient needs to take a higher dose than prescribed.
• The patient uses the medicine for reasons other than those for which the doctor prescribed it, such as "to calm down" or "to fall asleep".
• The patient has repeatedly tried to stop or control the use of the medicine but has been unsuccessful.
• After stopping the use of the medicine, the patient feels unwell and experiences improvement in their condition when they start using the medicine again (withdrawal effect).

If the patient experiences any of these symptoms, they should discuss the best treatment strategy with their doctor, including determining when it is appropriate to stop treatment and how to safely end treatment.

Withdrawal symptoms after stopping Matrifen use

Do not stop using this medicine suddenly. Withdrawal symptoms may occur, such as restlessness, difficulty sleeping, irritability, agitation, anxiety, rapid heartbeat (palpitations), increased blood pressure, nausea, vomiting, diarrhea, loss of appetite, tremors, chills, or sweating. If the patient wants to stop using this medicine, they should first talk to their doctor. The doctor will inform them how to do it; usually, it is done by gradually reducing the dose, so that any unpleasant withdrawal symptoms are minimized. See also section 2 "Withdrawal symptoms after stopping Matrifen use".

Matrifen and other medicines

Tell the doctor or pharmacist about all medicines the patient is currently taking or has recently taken, as well as any medicines they plan to take.
This includes all over-the-counter medicines or herbal remedies. When buying other medicines at the pharmacy, tell the pharmacist that you are using Matrifen.
The attending doctor knows which medicines can be safely used with Matrifen. The patient will require close monitoring if they are using certain medicines listed below or if they stop using certain medicines listed below, as this may affect the required strength of Matrifen.
In particular, tell the doctor or pharmacist if the patient is taking:

• Other opioid painkillers (such as buprenorphine, nalbuphine, or pentazocine) and certain painkillers for nerve pain (gabapentin and pregabalin).
• Sleeping pills (such as temazepam, zaleplon, or zolpidem).
• Tranquilizers (such as alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and antipsychotic medicines (such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).
• Muscle relaxants (such as cyclobenzaprine or diazepam).
• Certain antidepressants known as SSRI or SNRI (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, or venlafaxine) - see below.
• Certain antidepressants or medicines used to treat Parkinson's disease known as IMAO (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). Do not use Matrifen for 14 days after stopping these medicines - see below.
• Certain antihistamines, especially those that cause drowsiness (such as chlorpheniramine, clemastine, cyproheptadine, diphenhydramine, or hydroxyzine).
• Certain antibiotics (such as erythromycin or clarithromycin).
• Antifungal medicines (such as itraconazole, ketoconazole, fluconazole, or voriconazole).
• Medicines used to treat HIV infection (such as ritonavir).
• Anti-arrhythmic medicines (such as amiodarone, diltiazem, or verapamil).
• Antituberculosis medicines (such as rifampicin).
• Certain antiepileptic medicines (such as carbamazepine, phenobarbital, or phenytoin).
• Certain medicines used to treat nausea and motion sickness (such as phenothiazines).
• Certain medicines used to treat heartburn and stomach ulcers (such as cimetidine).
• Certain medicines used to treat coronary artery disease (angina pectoris) or high blood pressure (such as nicardipine).
• Certain medicines used to treat blood cancers (such as idelalisib).

Using Matrifen with antidepressants

The risk of side effects increases when used with certain antidepressants. There may be an interaction between Matrifen and these medicines, and the patient may experience changes in their mental state, such as agitation, hallucinations, and other effects such as changes in blood pressure, rapid heartbeat, high temperature, excessive reflexes, coordination disorders, muscle stiffness, nausea, vomiting, and diarrhea (these may be symptoms of serotonin syndrome). When using these medicines together, the doctor may want to closely monitor the patient for such side effects, especially when starting treatment or changing the dose of the medicine.

Using Matrifen with medicines that act on the central nervous system, including alcohol and certain narcotic medicines

Using Matrifen with tranquilizers such as benzodiazepines or other medicines with similar effects increases the risk of drowsiness, breathing problems (respiratory depression), coma, and can be life-threatening. Therefore, concurrent use should only be considered when no other treatment options are available.
If the doctor prescribes Matrifen with tranquilizers, the dose and duration of concurrent treatment should be determined by the doctor.
Tell the doctor about all tranquilizers being taken and strictly follow the prescribed dose of the medicine. It may be helpful to inform friends or relatives to be aware of the above symptoms. If such symptoms occur, contact a doctor.

Surgical procedures

If the patient suspects they may have anesthesia, they should tell their doctor or dentist that they are using Matrifen.

Using Matrifen with alcohol

Do not drink alcohol before talking to the attending doctor.
Matrifen may cause drowsiness and slow breathing. Alcohol can enhance these effects.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before using this medicine.
Matrifen should not be used during pregnancy, unless discussed with a doctor.
Matrifen should not be used during the perinatal period, as it may cause respiratory depression in the newborn.
Long-term use of Matrifen during pregnancy may cause withdrawal symptoms in the newborn (such as loud crying, trembling, seizures, insufficient food intake, and diarrhea), which can be life-threatening if not recognized and treated. If withdrawal symptoms are suspected in the child, contact a doctor immediately.
Do not use Matrifen during breastfeeding. Do not breastfeed for 3 days after removing the Matrifen patch. The medicine may pass into breast milk.

Driving and using machines

Matrifen may affect the ability to drive and use machines, as it can cause drowsiness and dizziness. If such symptoms occur, do not drive or operate any machines or tools. Do not drive until you know how the medicine affects you.
Talk to your doctor or pharmacist if you are unsure whether you can drive safely while using this medicine.

3. How to use Matrifen

Always use this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
The doctor will decide which strength of Matrifen is suitable for the patient, based on the severity of the pain, the patient's overall condition, and the pain treatment used so far.
Before starting and regularly during treatment, the doctor will also discuss with the patient what to expect from using Matrifen, when and for how long to take it, when to consult a doctor, and when to stop using the medicine (see also section 2 "Withdrawal symptoms after stopping Matrifen use").

Where to apply the patch

Adults

• Apply patches to a flat area of the upper body or arm (avoiding joint areas).

Children

• To minimize the risk of the child touching or removing the patch, apply it to the upper back.
• Check frequently to ensure the patch is properly attached to the skin.
• It is essential to ensure the child does not remove the patch and put it in their mouth, as this can be life-threatening or fatal.
• Monitor the child closely for 48 hours after:
• Applying the first patch
• Applying a patch with a higher dose.
• The effect of the patch may be delayed after the first application. During this time, the child may need to take additional painkillers. The doctor will inform you about this.

Adults and children

Do not apply the patch:

• to the same place twice in a row
• to areas with movement (near joints), irritated, or damaged skin.
• to very hairy skin. If there is hair, do not shave it (shaving irritates the skin). Instead, cut the hair as close to the skin as possible.

Applying the patch

Step 1: Preparing the skin

• Make sure the skin is completely dry, clean, and cool before applying the patch.
• If the skin needs to be cleaned, do so with cold water.
• Do not use soap or other cleansers, oils, creams, lotions, or talcum powder before applying the patch.
• Do not apply the patch immediately after a hot bath or shower.

Step 2: Opening the pouch

• Each patch is packaged in an individual pouch.
• Cut the pouch with scissors along the dotted line.
• Gently, completely cut off the edge of the pouch, taking care not to damage the patch inside.

• Hold the open pouch by both edges and pull apart.
• Remove the patch and apply it immediately.
• Keep the empty pouch to use later to dispose of the used patch.
• Each patch can only be used once.
• Do not remove the patch from the pouch until you are ready to apply it.
• Check the patch for damage.
• Do not use patches that are cut, broken, or damaged in any way.
• Never divide or cut patches.

Step 3: Removing the backing and applying the patch to the skin

• Make sure the clothing in the patch application area is loose; do not wear tight, elastic bands or bandages.
• Carefully peel off one half of the protective backing from the center of the patch. Avoid touching the adhesive side of the patch.
• Apply the adhesive side of the patch to the skin.
• Remove the second part of the protective backing and press the entire patch firmly onto the skin with your hand.
• Hold for at least 30 seconds. Make sure the patch is fully attached, especially at the edges.

Step 4: Removing the patch

• Immediately after removing the patch, fold it in half, so the adhesive sides stick together.
• Place it in the original pouch and dispose of it according to the pharmacist's instructions.
• Keep used patches out of sight and reach of children - even used patches still contain medicine that can be harmful to children and life-threatening.

Step 5: Washing hands
