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

This medicine is called Fentanilo Matrix STADA.

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 medication and who require continuous pain treatment.

Fentanilo Matrix STADA contains a medicine called fentanilo. It belongs to a group of strong painkillers known as opioids.

2. What you need to know before starting to use Fentanilo Matrix STADA

Do not use Fentanilo Matrix STADA:

• If you are allergic to fentanyl or to 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 surgery.
• If you have difficulty breathing with slow or weak breathing.

Do not use this medicine if you or your child are in any of the situations above. If you are unsure, consult your doctor or pharmacist before using Fentanilo Matrix STADA.

Warnings and precautions

Fentanilo Matrix Stada may have life-threatening adverse effects in individuals who are not regularly using prescribed opioids. Fentanilo Matrix Stada is a medicine that could be life-threatening to children, even if the patches have already been used. Please note that an adhesive patch (used or unused) may be attractive to a child, and if it adheres to the child's skin or if the child puts it in their mouth, the result could be fatal. Store this medicine in a secure and safe place, out of reach of others – see section 5 for more information.

If the patch sticks to another person

The patch must only be used on the skin of the person for whom the doctor has prescribed it. There have been some cases reported where the patch has accidentally adhered to another family member due to close physical contact or sharing the same bed with the person wearing the patch. If the patch accidentally sticks to another person (particularly a child), the medicine from the patch may pass through the other person's skin and may cause serious adverse effects, such as difficulty breathing, slow or weak breathing, which could be fatal. If the patch adheres to another person’s skin, remove it immediately and seek medical attention.

Take special care with Fentanilo Matrix Stada

Consult your doctor or pharmacist before using 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 elderly, as you may be more sensitive to the effects of this medicine.
• If you have a disorder 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 using Fentanilo Matrix Stada.

While using the patch, inform your doctor if you experience breathing problems during sleep.

Opioids such as fentanyl can cause sleep-related breathing disorders such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low blood oxygen levels). Speak with 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 (e.g., pain in a different part of your body).
• Pain from touch 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 Stada

• Fentanyl may cause unusual drowsiness and may slow or weaken your breathing. In very rare cases, these breathing problems can be life-threatening or even fatal, especially in people who have not previously used strong opioid painkillers (such as fentanyl 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 immediately to the nearest hospital.
  • Keep the person moving and talking as much as possible.
• If you develop a fever while using fentanyl, speak with your doctor. This may increase the amount of medicine passing through your skin.
• Fentanyl may cause constipation; speak with your doctor or pharmacist for advice on how to prevent or relieve constipation.

The complete list of possible adverse effects can be found in section 4.

Fentanyl, like other opioids, may affect the normal production of hormones in the body such as cortisol, prolactin, or sex hormones, especially if you have used fentanyl for long periods. The effects of these hormonal changes may include feeling unwell (including nausea), loss of appetite, fatigue, weakness, dizziness, low blood pressure, infertility, or reduced sexual desire.

In addition, female patients may experience changes in their menstrual cycle, while male patients may experience impotence or breast enlargement. If you notice any of these signs, consult your doctor.

While wearing the patch, do not expose it to direct heat sources such as heating pads, electric blankets, hot water bottles, heated water beds, or heat lamps or tanning lamps. Avoid prolonged sun exposure, hot baths, saunas, or hot tubs. Doing so 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 painkillers may make the drug 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 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 may cause dependence and/or addiction.

Repeated use of fentanyl may also lead to dependence, abuse, and addiction, which could result in a 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 medicine you need to use or how often you use it. You may feel a need to continue using the medicine 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 family member have abused alcohol or been dependent on alcohol, prescription medicines, or illegal drugs ("addiction").
• You smoke.
• You have ever had mood disorders (depression, anxiety, or a personality disorder) or have received psychiatric treatment 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 prescribed, e.g., "to stay calm" 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 feel better once you take it again ("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 medicine, and how to do so safely.

Withdrawal symptoms when stopping fentanyl

Do not stop using this medicine abruptly. Withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, awareness of your heartbeat (palpitations), increased blood pressure, feeling sick or being sick, diarrhea, loss of appetite, tremors, chills, or sweating may occur. If you wish to stop using this medicine, speak with your doctor first. Your doctor will advise you on how to do so, usually by gradually reducing the dose to minimize unpleasant withdrawal effects.

Other medicines and Fentanilo Matrix Stada

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines. This includes medicines bought without a prescription and herbal remedies. You should also inform your pharmacist that you are using fentanyl if you buy any medicine from the pharmacy.

Your doctor will know which medicines can be safely taken with fentanyl. You may need to be monitored more closely if you are taking any of the types of medicines listed below or if you stop taking any of them, as this may affect the dose of fentanyl you require.

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

• Other pain medicines, such as other opioid analgesics (e.g., buprenorphine, nalbuphine, or pentazocine) and some nerve pain medicines (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 disorders (antipsychotics, such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).
• Medicines to relax 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). – more information below
• Some medicines used to treat depression or Parkinson’s disease called MAOIs (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). You must not use fentanyl within 14 days of stopping these medicines. – more information below
• Some antihistamines, especially those that cause drowsiness (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 dizziness (such as phenothiazines).
• Some medicines used to treat heartburn 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 Stada 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 state such as agitation, seeing, feeling, hearing, or smelling things that are not present (hallucinations), and other effects such as changes in blood pressure, rapid heartbeat, high body temperature, hyperactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting, and diarrhea (which could be signs of Serotonin Syndrome). If used together, your doctor may need to monitor you closely for these side effects, especially when starting treatment or when the dose is changed.

Use with central nervous system depressants, including alcohol and some narcotic medicines

Concomitant use of fentanyl and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and may be potentially fatal. Because of this, concomitant use should only be considered when no other treatment options are possible.

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

Inform your doctor about all sedative medicines you are taking and follow your doctor’s dosing recommendations closely. It may be helpful to inform friends or family members about the signs and symptoms mentioned above. Contact your doctor if you experience such symptoms.

Do not drink alcohol while using fentanyl, unless you have first discussed it with your doctor.

Surgery

If you are scheduled to 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.

Prolonged use of fentanyl during pregnancy may cause withdrawal symptoms (such as high-pitched crying, restlessness, seizures, poor feeding, and diarrhea) in your newborn baby, which could be potentially fatal if not recognized and treated. Speak with your doctor immediately if you think your baby may have withdrawal symptoms.

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

Driving and using machines

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

Speak with your doctor or pharmacist if you have any doubts about whether it is safe for you to drive while using this medicine.

3. How to use Fentanilo Matrix STADA

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

Your doctor will decide which fentanyl concentration is most suitable for you, taking into account the intensity 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 you can 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 symptoms when stopping fentanyl").

Daily activities while using patches

• The patches are water-resistant.
• You may shower or bathe with the patch in place, but do not rub it.
• If your doctor agrees, you may exercise or engage in physical activity while wearing the patch.
• Do not use hot whirlpool baths.
• Do not cover the patch with tight or elastic fabrics.
• While wearing the patch, do not expose it to direct heat sources such as heating pads, electric blankets, hot water bottles, heated water beds, heat lamps, or tanning lamps.

If pain worsens

• If your pain suddenly worsens after applying the last patch, check your patch. If it is no longer adhering properly or has fallen off, replace the patch (also see section “If the patch comes loose”).
• If your pain worsens over time while using the patches, your doctor may try patches with a higher dose or prescribe additional painkillers (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 a patch with the wrong dose

If you have applied too many patches or a patch with the wrong dose, remove them immediately and contact your doctor, go to a hospital, or call the Toxicology Information Service at 91 562 04 20, indicating the medication and the amount applied.

Symptoms of overdose include difficulty breathing or weak breathing, fatigue, extreme drowsiness, inability to think clearly or to walk or speak normally, and feeling weak, dizzy, or confused. An overdose may also cause a brain disorder known as toxic leukoencephalopathy.

If you forget to change the patch

• If you forget to change the patch, do so as soon as you remember, and note the date and time. Resume changing the patch every 3 days (72 hours) as usual.
• If you are significantly delayed, you should speak with your doctor, as you may need additional painkillers, but do not apply extra patches.

  • On the trunk or arm
  • On the upper back of your child
• Inform your doctor about this and keep the patch in place for another 3 days (72 hours) or for the time your doctor specifies, before changing the patch in the usual way.
• If patches tend to come loose frequently, consult your doctor, pharmacist, or nurse.

If you want to stop using the patches

• Do not stop using this medication abruptly. If you wish to stop using this medication, speak with your doctor first. Your doctor will advise you on how to do so, usually by gradually reducing the dose to minimize unpleasant withdrawal symptoms. See also section 2, “Withdrawal symptoms when stopping Fentanilo Matrix Stada.”
• If you stop using the patches, do not reuse them without first consulting your doctor. You may need a different dose when restarting treatment.

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