This medicine is called Fentanyl Matrix Kern Pharma.

The patches help to relieve very strong and long-lasting pain:

Fentanyl Matrix Kern Pharma contains a medicine called fentanyl. It belongs to a group of strong pain relievers called opioids.

Do not use Fentanyl Matrix Kern Pharma:

• If you are allergic to fentanyl or any of the other ingredients of this medicine (listed in section 6).
• If you have short-term pain, such as sudden pain or pain after an operation.

Warnings and precautions

If the patch sticks to another person

The patch should only be used on the skin of the person for whom the doctor has prescribed it. There have been cases where the patch has accidentally stuck to another family member through close physical contact or sharing the same bed with the person wearing the patch. If the patch accidentally sticks to another person (especially a child), the medicine in the patch can pass through the skin of the other person and can cause serious side effects, such as breathing difficulties, with slow or weak breathing that can be fatal. If the patch sticks to someone else's skin, it should be removed immediately and a doctor should be consulted.

Be especially careful with Fentanyl Matrix Kern Pharma

Consult your doctor or pharmacist beforeusing this medicine if you are in any of the following situations. Your doctor will need to monitor you more closely:

• If you have ever had lung or breathing problems.
• If you have ever had heart, liver, or kidney problems, or low blood pressure.
• If you have ever had a brain tumor.
• If you have ever had persistent headaches or a head injury.
• If you are an elderly person, as you may be more sensitive to the effects of this medicine.
• If you have a condition called "myasthenia gravis", where the muscles become weak and tire easily.

If you meet any of the above conditions (or if you are not sure), consult your doctor or pharmacist before using Fentanyl Matrix Kern Pharma.

Tell your doctor if you have breathing problems while sleeping.Opioids like fentanyl can cause sleep-related breathing disorders such as sleep apnea (pauses in breathing while sleeping) and sleep-related hypoxemia (low oxygen levels in the blood). Talk to your doctor if you, your partner, or caregiver notice any of the following symptoms:

• pauses in breathing while sleeping
• waking up at night due to lack of air
• difficulty staying asleep
• excessive sleepiness during the day

Your doctor may decide to change the dose.

Tell your doctor if you notice a change in the pain you feel. If you feel:

• that the patch no longer relieves the pain
• an increase in pain
• a change in the way you feel the pain (for example, you feel pain in another part of your body)
• pain when there should be no pain.

Do not change the dose on your own. Your doctor may decide to change the dose or change the treatment.

Side effects and Fentanyl Matrix Kern Pharma

• Fentanyl Matrix Kern Pharma can make you feel extremely drowsy and can slow down your breathing. In rare cases, these breathing problems can be life-threatening or even fatal, especially in people who have not used strong opioid pain relievers before (such as Fentanyl Matrix Kern Pharma or morphine). If you, your partner, or caregiver notice that the person wearing the patch is unusually drowsy, with slow or weak breathing:

• Remove the patch.
• Call a doctor or go to the nearest hospital immediately.
• Make the person move and talk as much as possible.

• If you have a fever while using Fentanyl Matrix Kern Pharma, talk to your doctor. This can increase the amount of medicine that passes through your skin.
• Fentanyl Matrix Kern Pharma can cause constipation; talk to your doctor or pharmacist for advice on how to prevent or relieve constipation.

In section 4, you can find the complete list of possible side effects.

When wearing the patch, do not expose it to direct heat, such as heat pads, electric blankets, hot water bottles, water beds, heat lamps, or tanning lamps. Do not take sunbaths or prolonged hot baths and do not use saunas or hot tubs. If you do, you may increase the amount of medicine released from the patch.

Long-term use and tolerance

This medicine contains fentanyl, an opioid. Repeated use of opioid pain relievers can make the medicine less effective (the body gets used to it, which is known as pharmacological tolerance). You may also become more sensitive to pain when using Fentanyl Matrix Kern Pharma. This is known as hyperalgesia. Increasing the dose of the patches may continue to reduce the pain for a while, but it can also be harmful. If you notice that the medicine is becoming less effective, consult your doctor. Your doctor will decide whether to increase the dose or gradually reduce the use of Fentanyl Matrix Kern Pharma.

Dependence and addiction

Repeated use of Fentanyl Matrix Kern Pharma can also lead to dependence, abuse, and addiction, which can result in a potentially fatal overdose. The risk of these side effects may be greater with higher doses and longer use. Dependence or addiction can cause a feeling of lack of control over the amount of medicine you need to use or how often you need to use it. You may feel the need to continue using the medicine even if it no longer helps to relieve the pain.

The risk of dependence or addiction varies from person to person. The risk of becoming dependent on or addicted to Fentanyl Matrix Kern Pharma may be greater if:

• You or a family member have abused alcohol or have been dependent on it, or have abused prescription medicines or illegal drugs ("addiction").
• You smoke.
• You have ever had mood problems (depression, anxiety, or personality disorder) or have received treatment from a psychiatrist for other mental health problems.

If you notice any of the following signs while using Fentanyl Matrix Kern Pharma, it could be a sign of dependence or addiction.

• You need to use the medicine for longer than prescribed by your doctor.
• You need to use a higher dose than recommended.
• You are using the medicine for reasons other than those prescribed, for example, "to feel calm" or "to help you sleep".
• You have made repeated unsuccessful attempts to stop using the medicine or control your use.
• You feel unwell when you stop using the medicine, and you feel better once you start taking it again ("withdrawal symptoms").

If you notice any of these signs, consult your doctor to determine the best treatment option for you, when it is appropriate to stop the medicine, and how to do it safely.

Withdrawal syndrome when stopping treatment with Fentanyl Matrix Kern Pharma

Do not stop using this medicine suddenly. Withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhea, loss of appetite, tremors, chills, or sweating may occur. If you want to stop using this medicine, talk to your doctor first. Your doctor will tell you how to do it, usually by gradually reducing the dose so that the unpleasant withdrawal effects are minimal.

Using Fentanyl Matrix Kern Pharma with other medicines

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 and herbal medicines. You should also tell your pharmacist that you are using Fentanyl Matrix Kern Pharma if you buy any medicines from the pharmacy.

Your doctor will know which medicines can be safely taken with Fentanyl Matrix Kern Pharma. You may need to be closely monitored if you are taking any of the following types of medicines or if you stop taking any of the following types of medicines, as this can affect the dose of Fentanyl Matrix Kern Pharma that you need.

In particular, tell your doctor or pharmacist if you are taking:

• Other pain medicines, such as other opioid pain relievers (e.g., buprenorphine, nalbuphine, or pentazocine) and some pain relievers for nerve pain (gabapentin and pregabalin).
• Medicines to help you sleep (such as temazepam, zaleplon, or zolpidem).
• Medicines to help you calm down (tranquilizers, such as alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and medicines for mental health problems (antipsychotics, such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).
• Medicines to relax 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.
• Some medicines used to treat depression or Parkinson's disease called MAOIs (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). You should not use Fentanyl Matrix Kern Pharma in the 14 days after stopping these medicines – see below for more information.
• Some antihistamines, especially those that cause drowsiness (such as chlorpheniramine, clemastine, cyproheptadine, diphenhydramine, or hydroxyzine).

• Some medicines used to treat heartburn or stomach ulcers (such as cimetidine).
• Some medicines used to treat angina (chest pain) or high blood pressure (such as nicardipine).
• Some medicines used to treat blood cancer (such as idelalisib).

Using Fentanyl Matrix Kern Pharma with central nervous system depressants, including alcohol and some narcotic medicines

Using fentanyl and sedative medicines such as benzodiazepines or related medicines at the same time increases the risk of drowsiness, breathing difficulties (respiratory depression), coma, and can be fatal. Therefore, using them together should only be considered when other treatment options are not possible.

However, if your doctor prescribes fentanyl with sedative medicines, the dose and duration of concomitant treatment should be limited by your doctor.

Tell your doctor about all sedative medicines you are taking and follow your doctor's recommendations regarding the dose carefully. It may be useful to inform friends or family members so they are aware of the signs and symptoms mentioned above. Contact your doctor when you experience such symptoms.

Do not drink alcohol while using Fentanyl Matrix Kern Pharma unless you have talked to your doctor first.

Using Fentanyl Matrix Kern Pharma with antidepressants

The risk of side effects increases if you are taking medicines such as certain antidepressants. Fentanyl Matrix Kern Pharma can interact with these medicines, and you may experience changes in your mental state such as agitation, seeing, feeling, hearing, or smelling things that are not there (hallucinations), and other effects such as changes in blood pressure, rapid heartbeat, high body temperature, overactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting, and diarrhea (these could be signs of a serotonin syndrome). If used together, your doctor may want to monitor you closely to detect these side effects, especially when starting treatment or when changing the dose of the medicine.

Use in athletes

Athletes are informed that this medicine contains a component that can result in a positive doping test.

Operations

If you are going to have an operation, tell your doctor or dentist that you are using Fentanyl Matrix Kern Pharma.

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.

Fentanyl Matrix Kern Pharma should not be used during pregnancy, unless you have discussed it with your doctor.

Fentanyl Matrix Kern Pharma should not be used during labor, as the medicine can affect the breathing of the newborn baby.

Long-term use of Fentanyl Matrix Kern Pharma during pregnancy can cause withdrawal symptoms in your newborn baby, such as high-pitched crying, irritability, convulsions, poor feeding, and diarrhea, which can be life-threatening if not recognized and treated. Talk to your doctor immediately if you think your baby may have withdrawal symptoms.

Do not use Fentanyl Matrix Kern Pharma if you are breastfeeding. You should not breastfeed for 3 days after removing the Fentanyl Matrix Kern Pharma patch. This is because the medicine can pass into breast milk.

Adults and children:

Do not apply the patch to

• The same site twice in a row.
• Areas that move a lot (joints), irritated skin, or skin with wounds.

• Do not apply the patch immediately after a hot bath or shower.

Step 2: Open the envelope

• Each patch is sealed in its own envelope.

• Break or cut to open the envelope.
• Gently tear or cut along the edge of the envelope (if using scissors, make the cut along the sealed edge to avoid damaging the patch).
• Hold the two parts of the open envelope and pull to separate them.

• Press this adhesive part of the patch onto the skin.
• Remove the other part of the protective layer and press the entire patch onto the skin with the palm of your hand.
• Hold it pressed for at least 30 seconds. Make sure the patch is well stuck, especially around the edges.

Step 4: Dispose of the patch

• As soon as you remove the patch, fold it in half, so that the adhesive side sticks to itself.
• Put it back in the original envelope and throw it away following the instructions of your pharmacist.
