1. What is Fentanilo Matrix Viatris and what is it used for

The name of your medicine is Fentanilo Matrix Viatris.

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

  • In adults who need continuous treatment for pain.
  • In children over 2 years who are already using opioid medicines and who need continuous treatment for pain.

Fentanilo Matrix Viatris contains a medicine called fentanyl. It belongs to a group of strong painkillers called opioids.

2. What you need to know before you use Fentanilo Matrix Viatris

Do not use Fentanilo Matrix Viatris if:

  • You are allergic to fentanyl or any of the other ingredients of this medicine (listed in section 6).
  • You have pain that lasts only for a short period, such as sudden pain or pain after an operation.
  • You have breathing difficulties, with slow or shallow breathing.

Do not use this medicine if you or your child have any of the above conditions. If in doubt, consult your doctor or pharmacist before using Fentanilo Matrix Viatris.

Warnings and precautions

  • Fentanilo Matrix Viatris can have potentially life-threatening side effects in people who do not regularly use prescribed opioid medicines.
  • Fentanilo Matrix Viatris is a potentially life-threatening medicine for children, even if the patches have been used before. Note that an adhesive patch (used or unused) can be tempting for a child and if it sticks to a child's skin or if it is put in the mouth, it can be life-threatening.
  • Keep this medicine in a safe place, out of the reach of other people, for more information see section 5.

Applying the patch to another person

The patch should only be used on the skin of the person it has been prescribed for. There have been reports of patches accidentally sticking to a family member if there is physical contact or if the same bed is shared with the person wearing the patch. A patch that accidentally sticks to another person (especially a child) can cause the medicine to pass through the skin of the other person and cause serious side effects, such as breathing difficulties, with slow or shallow breathing, which can be life-threatening. If the patch sticks to another person's skin, remove it immediately and seek medical attention.

Be careful with Fentanilo Matrix Viatris

Consult your doctor or pharmacist before using this medicine if any of the following apply to you; your doctor may need to monitor 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 tumor.
  • You have ever had persistent headaches or head injuries.
  • You are elderly, you may be more sensitive to the effects of this medicine.
  • You have a condition called "myasthenia gravis", where the muscles become weak and easily tired.

If any of the above apply to you (or if you are not sure), consult your doctor or pharmacist before using fentanyl.

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

  • breathing pauses 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.

While using the patch, tell your doctor if you notice a change in the pain you feel.If you:

  • feel that the patch no longer relieves the pain
  • experience an increase in pain
  • notice a change in the way you feel the pain (for example, you feel pain in another part of your body)
  • feel pain when there is contact with your body that should not cause pain.

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

Side effects and Fentanilo Matrix Viatris

  • Fentanyl may make you unusually drowsy and may cause you to breathe more slowly or shallowly. In rare cases, these breathing problems can be life-threatening, especially in people who have not previously used strong opioid painkillers (such as Fentanilo Matrix Viatris) or morphine. If you, your partner or caregiver notice that the person wearing the patch is unusually drowsy, with slow or shallow breathing:
  • Remove the patch.
  • Call a doctor or go to the nearest hospital immediately.
  • Keep the person moving and talking as much as possible.
  • If you have a fever while using fentanyl, tell your doctor: this can increase the amount of medicine that passes through the skin.
  • Fentanyl can cause constipation, consult your doctor or pharmacist for advice on how to avoid or relieve constipation.

See section 4 for a complete list of possible side effects.

Long-term use and tolerance

This medicine contains fentanyl, an opioid. Repeated use of opioid painkillers 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. 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 it is better to increase the dose or gradually reduce the use of fentanyl.

Dependence and addiction

This medicine contains fentanyl, which is an opioid. It can cause dependence and/or addiction.

Repeated use of fentanyl can also lead to dependence, abuse and addiction, which can result in a potentially life-threatening overdose. The risk of these side effects may be greater with a higher dose 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 relieves the pain.

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

  • You or any member of your family have abused alcohol or have been dependent on it, or have abused prescription medicines or illegal drugs ("addiction").
  • You smoke.
  • You have ever had problems with your mood (depression, anxiety or personality disorder) or have been treated by a psychiatrist for other mental illnesses.

If you notice any of the following symptoms while using fentanyl, 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 calm down" or "to help you sleep".
  • You have made repeated unsuccessful attempts to stop using the medicine or control its use.
  • You feel unwell when you stop using the medicine, and you feel better once you start using it again ("withdrawal symptoms").

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

If you are using the patch, do not expose it to direct heat sources, such as electric blankets, hot water bottles, water beds, heat lamps or tanning lamps. Do not sunbathe or take long hot baths. Do not go to saunas or steam rooms or spas. If you do, you may increase the amount of medicine you receive from the patch.

Other medicines and Fentanilo Matrix Viatris

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines. This includes medicines that you buy without a prescription or herbal medicines. If you buy medicines from a pharmacy, you must also tell the pharmacist that you are using fentanyl.

Your doctor will know which medicines you can safely take with fentanyl. You may need to be monitored closely if you are taking or stop taking some of the types of medicines listed below, as this may affect the strength of fentanyl you need.

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

  • Other painkillers, such as other strong opioid painkillers (e.g. buprenorphine, nalbuphine or pentazocine) and some painkillers for nerve pain (gabapentin and pregabalin).
  • Medicines to help you sleep (such as temazepam, zaleplon or zolpidem).
  • Medicines to calm you down (tranquilizers, such as alprazolam, clonazepam, diazepam, hydroxyzine or lorazepam) and medicines for mental illnesses (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.
  • Some medicines used to treat depression or Parkinson's disease called MAOIs (such as isocarboxazid, phenelzine, selegiline or tranylcypromine). Do not take fentanyl in the 14 days after stopping these medicines: see below.
  • Some antihistamines, especially those that make you drowsy (such as chlorpheniramine, clemastine, cyproheptadine, diphenhydramine or hydroxyzine).
  • Some antibiotics used to treat infections (such as erythromycin or clarithromycin).
  • Medicines used to treat fungal infections (such as itraconazole, ketoconazole, fluconazole or voriconazole).
  • Medicines used to treat HIV infection (such as ritonavir).
  • Medicines used to treat irregular heartbeats (such as amiodarone, diltiazem or verapamil).
  • Medicines used to treat tuberculosis (such as rifampicin).
  • Some medicines used to treat epilepsy (such as carbamazepine, phenobarbital or phenytoin).
  • Some medicines used to treat nausea or vomiting (such as phenothiazines).
  • Some medicines used to treat sunburn or 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).

Fentanilo Matrix Viatris with antidepressants

The risk of side effects increases if you are taking medicines such as certain antidepressants. Fentanyl can interact with these medicines and you may experience changes in your mental state, such as excitement, 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.

Use with central nervous system depressants, including alcohol and certain narcotics

Tell your doctor if you are taking any other medicine that slows down your central nervous system (CNS depressant). For example, CNS depressants are medicines that make you drowsy, reduce anxiety or reduce consciousness (see also "Other medicines and Fentanilo Matrix Viatris"); alcohol and certain narcotics are also CNS depressants. Taking these types of medicines with Fentanilo Matrix Viatris can cause severe drowsiness, reduced consciousness, breathing difficulties with slow or shallow breathing, coma or death.

Do not drink alcohol while using Fentanilo Matrix Viatris, unless you have talked to your doctor first.

Operations

If you think you are going to receive anesthesia, tell your doctor or dentist that you are using fentanyl.

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 should not be used during pregnancy, unless you have talked to your doctor.

Fentanyl should not be used during childbirth, as the medicine can affect the breathing of the newborn baby.

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

Driving and using machines

Fentanyl can affect your ability to drive and use tools or machines, as it can cause drowsiness or dizziness. If this happens, do not drive or use tools or machines. Do not drive while using this medicine until you know how it affects you.

Talk to your doctor or pharmacist if you are not sure if it is safe to drive while taking this medicine.

3. How to use Fentanilo Matrix Viatris

Follow the administration instructions for this medication exactly as indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

The doctor will decide which dose of Fentanilo Matrix Viatris is most suitable, taking into account the severity of the pain, your general condition, and the type of pain treatment you have received so far.

Before starting treatment and regularly during treatment, your doctor will also explain what you can expect from the use of fentanyl, when and for how long you should use it, when you should contact your doctor, and when you should stop using it (see also section 2, "Withdrawal syndrome when stopping fentanyl treatment").

Where to apply the patch

Adults

  • Place the patch on a smooth surface on the upper part of the body or the arm (not over a joint).

Use in children

  • Always apply the patch to the upper back, so the child cannot reach it and remove it.
  • Check frequently that the patch is still stuck to the skin.
  • It is essential that the child does not remove the patch and put it in their mouth, as this could pose a life-threatening risk.
  • Monitor your child closely for 48 hours after:
    • Applying the first patch.
    • Applying a patch with a higher dose.
  • It may take some time for the patch to have its maximum effect. Therefore, your child may need additional pain relievers until the patches are fully effective. Your doctor will advise you if necessary.

Adultsand children:

Do not apply the patch to

  • The same place twice in a row.
  • Areas that move a lot (joints), irritated skin, or skin with cuts.
  • Skin with a lot of hair. If there is hair, do not shave it (shaving irritates the skin). Instead, cut the hair with scissors as close to the skin as possible.

Applying a patch

Step 1: Skin preparation

  • Make sure the skin is completely dry, clean, and fresh before applying the patch.
  • If you need to wash the skin, wash it with water.
  • Do not use soap, oil, lotions, alcohol, or other cleansers that may irritate the skin.
  • Do not apply the patch immediately after a hot bath or shower.

Step 2: Open the pouch

  • Each patch is stored in a sealed bag.
  • To open the pouch, make a small cut near the sealed edge of the pouch with the tip of the scissors (figure 1).

Figure 1:

  • If your pain worsens suddenly after applying the last patch, check the patch. If it is no longer sticking well or has come off, replace the patch (see also the section If the patch comes off).
  • If the pain worsens over time while using the patches, your doctor may try a patch with a higher dose or give you an additional pain reliever (or both).
  • If increasing the patch dose does not help, your doctor may decide to stop using the patches.

If you have applied too many patches or the patch has an incorrect dose, remove them and contact your doctor or pharmacist immediately, call the Toxicology Information Service, phone 91 562 04 20 (indicating the medication and the amount applied), or go to the nearest hospital. Bring the packaging and remaining patches with you.

The signs of overdose include difficulty breathing or weak breathing, tiredness, extreme drowsiness, inability to think clearly, walk or talk normally, as well as fainting, dizziness, or confusion. An overdose can also cause a brain disorder known as toxic leukoencephalopathy.

If you forget to change the patch

  • If you forget, change the patch as soon as you remember and write down the day and time. Change the patch again after 3 days (72 hours), as usual.
  • If you delay changing the patch, you should talk to your doctor because you may need additional pain relievers, but do not apply another patch.

If a patch comes off

  • If a patch comes off before it is due to be changed, apply a new one immediately and write down the day and time. Use a new area of skin on:
  • The upper part of the body or the arm.
  • Your child's shoulder.
  • Tell your doctor what happened and leave the patch on for another 3 days (72 hours) or as indicated by your doctor, before changing the patch in the usual way.
  • If the patches continue to fall off, talk to your doctor, pharmacist, or nurse.

If you want to stop using the patches

  • Talk to your doctor if you want to stop using these patches.
  • If you have been using them for a while, your body may have gotten used to them. If you stop using them suddenly, you may not feel well.
  • If you stop using patches, do not start using them again without asking your doctor first. You may need a patch with a different dose when you start again.

If you have any other questions about using this medication, ask your doctor or pharmacist.
