  • If you are allergic to fentanyl or any of the other components of this medication (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 medication if you or your child is in any of the above circumstances. If you are unsure, consult your doctor or pharmacist before using Fentanilo Matrix Kern Pharma.

Warnings and precautions

  • Fentanilo Matrix Kern Pharma may have life-threatening adverse effects in people who are not regularly using prescribed opioids.
  • Fentanilo Matrix Kern Pharma is a medication that could be life-threatening to children, even if the patches have already been used. Note that a sticky patch (used or unused) may be tempting to a child, and if it sticks to the child's skin or if the child puts it in their mouth, the result could be fatal.
  • Keep this medication in a safe and protected place, out of reach of other people (see section 5 for more information).

If the patch sticks to another person

The patch must be used only on the skin of the person for whom the doctor prescribed it. There have been some cases where the patch has accidentally stuck to another family member by 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 medication from the patch may pass through the other person's skin and may cause severe adverse effects, such as difficulty breathing, slow or weak breathing that can be fatal. In the event that the patch sticks to someone else's skin, it must be removed immediately and the person must see a doctor.

Be especially careful with Fentanilo Matrix Kern Pharma

Consult your doctor or pharmacist before using this medication if you are in any of the following circumstances. Your doctor will have to monitor you more closely:

  • If you have ever had respiratory 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 trauma.
  • If you are an elderly person, as you may be more sensitive to the effects of this medication.
  • If you have a condition called "myasthenia gravis," in which your muscles weaken and tire easily.

If you meet any of the above conditions (or if you are unsure), consult your doctor or pharmacist before using Fentanilo Matrix Kern Pharma.

While using the patch, report to 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 observe any of the following symptoms:

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

Your doctor may decide to modify the dose.

While using the patch, report to 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
  • that there is a change in the way you feel the pain (for example, you feel pain in another part of your body)
  • pain when you come into contact with your body that should not cause pain.

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

Adverse effects and Fentanilo Matrix Kern Pharma

  • Fentanilo Matrix Kern Pharma may make you feel exceptionally sleepy and may slow down your breathing. In rare cases, these breathing problemsmay be life-threatening or even fatal, especially in people who have not used strong prescription painkillers (such as FentaniloMatrix Kern Pharmaor morphine) before. If you, or your partner or caregiver, observe that the person wearing the patch is unusually sleepy, breathing slowly or weakly:
  • 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 feverwhile using FentaniloMatrix Kern Pharma, talk to your doctor. This may increase the amount of medication that passes through your skin.
  • FentaniloMatrix Kern Pharmamay cause constipation; talk to your doctor or pharmacist for advice on how to prevent or relieve constipation.

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

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

Long-term use and tolerance

This medication contains fentanyl, an opioid. Repeated use of strong painkillers may make the medication less effective (your body gets used to it, which is known as pharmacological tolerance). It is also possible that you may become more sensitive to pain when using FentaniloMatrix Kern Pharma. This is known as hyperalgesia. Increasing the dose of the patches may continue to reduce pain for a while, but it may also be harmful. If you notice that the medication is losing its effectiveness, consult your doctor. Your doctor will decide whether it is better to increase the dose or to gradually reduce the use of FentaniloMatrix Kern Pharma.

Dependence and addiction

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

The repeated use of FentaniloMatrix Kern Pharmamay also cause dependence, abuse, and addiction, which could lead to a potentially fatal overdose. The risk of these adverse effects may be higher with a higher dose and longer use. Dependence or addiction may cause you to feel a lack of control over the amount of medication you should use or the frequency with which you should use it. You may feel the need to continue using the medication even if it no longer helps to relieve pain.

The risk of dependence or addiction varies from person to person. The risk of becoming dependent or addicted to FentaniloMatrix Kern Pharmamay be higher if:

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

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

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

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

Withdrawal syndrome when stopping treatment with Fentanilo Matrix Kern Pharma

Do not stop using this medication abruptly. You may experience 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. If you want to stop using this medication, talk to your doctor first. Your doctor will advise you on how to do it, usually by gradually reducing the dose to minimize unpleasant withdrawal symptoms.

Use of Fentanilo Matrix Kern Pharma with other medications

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication. This includes over-the-counter medications and herbal remedies. You should also inform your pharmacist that you are using Fentanilo Matrix Kern Pharma if you buy any medication at the pharmacy.

Your doctor will know which medications can be taken safely with Fentanilo Matrix Kern Pharma. They may need to monitor you closely if you are taking any of the types of medications listed below or if you stop taking any of the types of medications listed, as this may affect the dose of Fentanilo Matrix Kern Pharma you need.

Especially, inform your doctor or pharmacist if you are taking:

  • Other pain medications, such as other strong opioid painkillers (e.g., buprenorphine, nalbuphine, or pentazocine) and some pain medications for neuropathic pain (gabapentin and pregabalin).
  • Medications to help you sleep (e.g., temazepam, zaleplon, or zolpidem).
  • Medications to help you calm down (tranquilizers, e.g., alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and medications for mental health conditions (antipsychotics, e.g., aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).

  • Some medications used to treat angina (chest pain) or high blood pressure (e.g., nicardipine).
  • Some medications used to treat blood cancer (e.g., idelalisib).

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

The concomitant use of fentanyl and sedatives such as benzodiazepines or related medications increases the risk of drowsiness, breathing difficulties (respiratory depression), coma, and may be fatal. Therefore, concomitant use should only be considered when other treatment options are not possible.

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

Inform your doctor about all sedatives you are taking and follow your doctor's recommendations carefully regarding the dose. It may be helpful 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 Fentanilo Matrix Kern Pharma unless you have talked to your doctor first.

Use of Fentanilo Matrix Kern Pharma with antidepressants

The risk of adverse effects increases if you are taking certain antidepressants. Fentanilo Matrix Kern Pharma may interact with these medications, and you may experience changes in 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, hyperactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting, and diarrhea (which may 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 medication.

Use in athletes

It is reported to athletes that this medication contains a component that may result in a positive analytical result for doping control.

Surgeries
