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

The name of your medicine is Fentanilo Matrix Viatris.

The patches help relieve severe and long-lasting pain.

  • In adults who require continuous pain treatment.
  • In children over 2 years of age who are already using opioid medicines and who require continuous pain treatment.

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

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

Do not use Fentanilo Matrix Viatris if:

  • You are allergic to fentanyl or to any of the other ingredients of this medicine (listed in section 6).
  • You have pain that lasts only briefly, such as sudden pain or pain after surgery.
  • You have difficulty breathing, with slow or shallow breathing.

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

Warnings and precautions

  • Fentanilo Matrix Viatris may cause potentially life-threatening adverse effects in people who are not already regularly using prescribed opioid medicines.
  • Fentanilo Matrix Viatris is potentially fatal for children, even if the patches have already been used. Please note that a transdermal patch (used or unused) may be attractive to a child, and if it adheres to a child's skin or is placed in the mouth, the result may be fatal.
  • Keep this medicine in a secure, protected place out of reach of others. For further information, see section 5.

Application of the patch to another person

The patch must only be applied to the skin of the person for whom it has been prescribed. Cases have been reported in which patches have accidentally adhered to a family member through physical contact or by sharing the same bed as the person wearing the patch. A patch that accidentally adheres to another person (especially a child) may result in the medicine passing through that person's skin and causing serious adverse effects, such as difficulty breathing, slow or shallow breathing, which may be fatal. If a patch adheres to another person's skin, remove it immediately and seek medical attention.

Take special care with Fentanilo Matrix Viatris

Consult your doctor or pharmacist before starting to use this medicine if any of the following apply to you; your doctor may need to monitor you more closely if:

  • You have ever had lung or breathing problems.
  • You have ever had heart, liver, or kidney problems, or low blood pressure.
  • You have ever had a brain tumour.
  • You have ever had persistent headaches or head injuries.
  • You are elderly, as 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.

If any of the above conditions apply to you (or if you are unsure), consult your doctor or pharmacist before starting to use fentanyl.

While using the patch, inform your doctor if you have breathing problems during sleep.
Opioids such as fentanyl may cause sleep-related breathing disorders such as sleep apnoea (pauses in breathing during sleep) and sleep-related hypoxemia (low blood oxygen levels). Talk to your doctor if you, your partner, or caregiver notice any of the following symptoms:

  • Pauses in breathing during sleep
  • Waking up at night due to shortness of breath
  • Difficulty staying asleep
  • Excessive daytime sleepiness

Your doctor may decide to adjust the dose.

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

  • The patch no longer relieves your pain
  • An increase in pain
  • A change in the way you feel pain (for example, pain in another part of your body)
  • Pain caused by touch to your body that should not cause pain

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

Adverse effects and Fentanilo Matrix Viatris

  • Fentanyl may cause unusual drowsiness and slow or shallow breathing. In rare cases, these breathing problems may be potentially 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 or has 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 develop a fever while using fentanyl, inform your doctor: fever may increase the amount of medicine passing through the skin.

  • Fentanyl may cause constipation. Consult your doctor or pharmacist for advice on how to prevent or relieve constipation.

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

Long-term use and tolerance

This medicine contains fentanyl, an opioid. Repeated use of opioid analgesics may cause the drug to become less effective (the body becomes accustomed to it, known as pharmacological tolerance). You may also become more sensitive to pain while using fentanyl. This is known as hyperalgesia. Increasing the patch dose may continue to reduce pain for a time, but it may also be harmful. If you notice the medicine is losing effectiveness, 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 may cause dependence and/or addiction.

Repeated use of fentanyl may also lead to dependence, abuse, and addiction, which could result in potentially fatal overdose. The risk of these adverse effects may be higher with higher doses and prolonged use. Dependence or addiction may cause a feeling of lack of control over the amount of medication you need to take or how often you need to take it. You may feel a need to continue using the medication even if it does not help relieve pain.

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

  • You or any member of your family have abused alcohol or experienced dependence on alcohol, prescription medications, or illegal drugs (“addiction”).
  • You smoke.
  • You have ever had mood disorders (depression, anxiety, or a personality disorder) or have received treatment from 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 medication for longer than prescribed by your doctor.
  • You need to use a higher dose than recommended.
  • You are using the medication for reasons other than those prescribed, for example, “to stay calm” or “to help you sleep.”
  • You have made repeated unsuccessful attempts to stop using the medication or control its use.
  • You feel unwell when you stop using the medication and feel better once you resume taking it (“withdrawal effects”).

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

If you are wearing the patch, do not expose it to direct sources of heat, such as electric heating pads, electric blankets, hot water bottles, heated water beds, or heat or tanning lamps. Do not sunbathe or take prolonged hot baths. Do not visit saunas, hot tubs, or spas. Doing so may increase the amount of medication you receive from the patch.

Other medicines and Fentanilo Matrix Viatris

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines. This includes medicines you purchase without a prescription or herbal remedies. If you buy medicines at a pharmacy, you should 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 closely monitored if you are starting or stopping any of the following types of medicines, as this may affect the strength of fentanyl you require.

Specifically, tell your doctor or pharmacist if you are taking:

  • Other pain medicines, such as other opioid analgesics (e.g., buprenorphine, nalbuphine, or pentazocine) and some analgesics for neuropathic pain (gabapentin and pregabalin).

  • Medicines to help you sleep (such as temazepam, zaleplon, or zolpidem).

  • Medicines to help you relax (tranquilizers, such as alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and medicines for mental conditions (antipsychotics, such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).

  • Medicines to relax muscles (such as cyclobenzaprine or diazepam).

  • Some antidepressants called SSRIs or SNRIs (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, or venlafaxine). See information below.

  • Some medicines used to treat depression or Parkinson’s disease called MAOIs (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). You must not take fentanyl within 14 days of stopping these medicines: see information 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 arrhythmias (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 dizziness (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 adverse effects increases if you are taking medicines such as certain antidepressants. Fentanyl may interact with these medicines, and you may experience changes in mental status, such as agitation, seeing, feeling, hearing, or smelling things that are not there (hallucinations), and other effects such as changes in blood pressure, rapid heart rate, high body temperature, hyperactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting, and diarrhea.

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

Inform your doctor if you are taking any other medicine that slows down your central nervous system (CNS depressants). For example, CNS depressants include medicines that make you drowsy, reduce anxiety, or decrease 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 may cause severe drowsiness, decreased consciousness, breathing difficulties with slow or shallow breathing, coma, or death.

Do not drink alcohol while using Fentanilo Matrix Viatris unless you have first spoken with your doctor.

Surgery

If you think you may receive anesthesia, inform your doctor or dentist that you are using fentanyl.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

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

Fentanyl should not be used during labor, as the medicine may affect the newborn’s breathing.

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

Talk to your doctor or pharmacist if you are unsure whether it is safe to drive while taking this medicine.

3. How to use Fentanilo Matrix Viatis

Follow exactly the administration instructions for this medicine as indicated by your doctor. If in doubt, you should consult your doctor or pharmacist again.

Your doctor will decide which dose of Fentanilo Matrix Viatris is most suitable, taking into account the severity of your 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 to you what to expect from using 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 upon discontinuation of fentanyl treatment").

Use and changing of patches

  • There is enough medicine in each patch to last 3 days (72 hours).
  • You must change the patch every three days, unless your doctor has instructed otherwise.
  • Always remove the old patch before applying a new one.
  • Always change the patch at the same time of day every 3 days (72 hours).

Where to Apply the Patch

Adults

  • Apply the patch to a smooth area of the upper body or 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 to ensure the patch remains adhered to the skin.
  • It is important that the child does not remove the patch and put it in their mouth, as this could be life-threatening or even fatal.
  • Monitor your child closely during the first 48 hours after:
    • Application of the first patch.
    • Application of a patch with a higher dose.
  • It may take some time for the patch to reach its full effect. Therefore, your child may need additional pain relief until the patches become fully effective. Your doctor will advise you if necessary.

Adults and Children:

Do not apply the patch to

  • The same spot twice in a row.
  • Areas that move a lot (joints), irritated skin, or skin with cuts.
  • 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 using scissors.

Applying a Patch

Step 1: Skin Preparation

  • Ensure the skin is completely dry, clean, and cool before applying the patch.
  • If you need to wash the skin, use water only.
  • 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 pouch.
  • To open the pouch, make a small cut near the sealed edge using the tip of scissors (Figure 1).

Figure 1:

A hand holds a pair of scissors cutting the top of a medical container or blister pack
  • Gently tear the pouch open completely with your hands (Figure 2).

Figure 2:

Two hands carefully hold and tear the top edge of a square pouch to open it
  • Hold both sides of the opened pouch, pull them apart so the pouch opens on three sides, and remove the patch (Figure 3).

Figure 3:

Two hands with long nails holding and opening a rectangular package of a medical or pharmaceutical product
  • Remove the patch and use it immediately (Figure 4).

Figure 4:

A hand holds a square adhesive bandage with a gray central pad
  • Keep the empty pouch to dispose of the used patch later.
  • Use each patch only once.
  • Do not remove the patch from its pouch until you are ready to use it.
  • Check the patch for any damage.
  • Do not use the patch if it is split, cut, or appears damaged.
  • Never cut or divide the patch.

Step 3: Peel and Press

  • Ensure the patch is covered by loose clothing and not trapped under a strap or elastic band.
  • The patch should be applied immediately after opening the pouch. After removing the protective liner, carefully peel back half of the transparent protective layer away from the center of the patch. Try not to touch the adhesive side of the patch (Figure 5).

Figure 5:

Two hands holding and lifting a square adhesive dressing
  • Press this adhesive part of the patch onto the skin (Figure 6).

Figure 6:

Step 4: How to Dispose of the Patch

  • As soon as the patch is removed, fold it in half firmly so the adhesive sides stick together.
  • Return it to its original pouch and dispose of the pouch according to the instructions provided by your pharmacist.
  • Keep used patches out of sight and reach of children; even when used, patches still contain medication that could seriously harm or even be fatal to children.

Step 5: Washing

  • Always wash your hands with plain water after handling the patch.

When Will the Patches Start Working?

  • It may take some time for the first patch to reach its full effect.
  • Your doctor may provide you with other pain relievers, including for the first day.
  • Afterwards, the patch should help relieve your pain continuously, allowing you to stop taking other pain relievers. However, your doctor may prescribe additional pain relievers from time to time.

How Long Will You Use the Patches?

  • Fentanyl patches are for long-lasting pain. Your doctor will tell you how long you can continue using the patches.

If Pain Gets Worse

  • If your pain suddenly worsens after applying the last patch, check the patch. If it is no longer adhering properly or has come off, replace the patch (see also the section "If the Patch Comes Off").
  • If pain worsens over time while using the patches, your doctor may try a higher-dose patch or prescribe 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 Use Too Many Patches or Use a Patch with the Wrong Dose

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

Signs of overdose include difficulty breathing or weak breathing, extreme fatigue, excessive drowsiness, inability to think, walk, or speak 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 note the date and time. Then change the patch again after 3 days (72 hours), as usual.
  • If you delay changing the patch for a long time, speak to your doctor, as you may need additional pain relief, 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 note the date and time. Apply it to a new area of skin on:

  • The upper body or arm.

  • Your child's shoulder.

  • Inform your doctor about what happened and keep the patch in place for another 3 days (72 hours) or as directed by your doctor before changing it in the usual way.

  • If patches continue to fall off, speak to your doctor, pharmacist, or nurse.

If You Want to Stop Using the Patches

  • Talk to your doctor if you wish to stop using these patches.
  • If you have been using them for some time, your body may have become accustomed to them. Stopping them suddenly may make you feel unwell.
  • If you stop using patches, do not start using them again without first consulting your doctor. You may need a patch with a different dose when restarting.

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

4. Possible adverse effects
