The name of this medicine is Fentanilo Matrix Sandoz.

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

Fentanilo Matrix Sandoz contains a medicine called fentanyl. It belongs to a group of strong pain relievers called opioids.

• you have short-term pain, such as sudden pain or pain after an operation,
• you have breathing difficulties, with slow or weak breathing.

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

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, slow or weak breathing, which can be fatal. If the patch sticks to another person's skin, it should be removed immediately and a doctor should be consulted.

Be careful with Fentanilo Matrix Sandoz

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,
• you have ever had heart, liver, kidney, or low blood pressure problems,
• you have ever had a brain tumor,
• you have ever had persistent headaches or head injuries,
• you are an elderly patient - you may be more sensitive to the effects of this medicine,
• you have a condition called "myasthenia gravis", in which the muscles become weak and tired easily.

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

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 daytime sleepiness. Your doctor may decide to adjust 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,
• 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 is contact with your body that should not cause you pain.

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

Side effects and Fentanilo Matrix Sandoz

• Fentanyl can make you feel unusually sleepy and can slow down your breathing.

On rare occasions, these breathing problems can be life-threatening or even fatal, especially in people who have not previously used strong opioid pain relievers (such as fentanyl or morphine). If you, your partner, or caregiver notice that the person wearing the patch is unusually sleepy, with slow or weak 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 your skin,
  • Fentanyl 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 hot water bottles, electric blankets, heat pads, water beds, or heat 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 transdermal patches. 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 transdermal patches.

Dependence and addiction

Repeated use of Fentanilo Matrix Sandoz 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 Fentanilo Matrix Sandoz may be greater if:

• You or any member of your family have abused alcohol or have been dependent on it, or have taken 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 illnesses.

If you notice any of the following symptoms while using Fentanilo Matrix Sandoz, 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 take 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 symptoms when stopping Fentanilo Matrix Sandoz

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.

Other medicines and Fentanilo Matrix Sandoz

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

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

Fentanilo Matrix Sandoz 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 feeling agitated, 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.

Fentanilo Matrix Sandoz with central nervous system depressants, including benzodiazepines, 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 life-threatening. Because of this, using them together should only be considered when other treatment options are not possible.

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

Tell your doctor about all sedative medicines you are taking, and follow your doctor's dosing recommendations strictly. It may be helpful to inform friends or family members who 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 Sandoz unless you have talked to your doctor first.

Surgery

If you think you are going to have an operation, tell your doctor or dentist that you are using Fentanilo Matrix Sandoz.

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 labor, as the medicine can affect the breathing of the newborn.

Long-term use of fentanyl during pregnancy can cause withdrawal symptoms in your newborn baby, such as loud 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 if you are breastfeeding. You should not breastfeed for 3 days after removing the Fentanilo Matrix Sandoz patch. This is because the medicine can pass into breast milk.

Where to apply the patch

Adults

• Apply the patch to a flat area of the torso or arm (never over a joint).

Children

• Always apply the patch to the upper back so that your child has difficulty reaching it or removing it.
• Check from time to time 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 put their life in danger or be fatal.
• Keep your child under close observation for 48 hours after:

• Applying the first patch.
• Applying a patch with a higher dose.

• The patch may take some time to reach its maximum effect. Therefore, your child may need other painkillers until the patches are effective. Your doctor will explain this to you.

Adults and 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.
• Areas of skin with a lot of hair. If there is hair, do not shave it (shaving irritates the skin). Instead, cut it as close to the skin as possible.

Placing a patch

Step 1: Prepare the skin

• Before applying the patch, make sure your skin is completely dry, clean, and fresh.
• If you need to wash the skin, use only cold water.
• Do not use soap or other cleaners, creams, moisturizers, oils, or talcum powder before applying the patch.
• Do not apply the patch after a hot bath or shower.

Step 2: Open the pouch

• Each patch is sealed in its own pouch.
• Tear the pouch at the notch.
• Gently tear the edge of the pouch completely (if you use scissors, make the cut along the sealed edge to avoid damaging the patch).
• Hold both sides of the open pouch and pull to separate them.
• Remove the patch and use it immediately.
• Save 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.

• Carefully peel off the first part of the shiny plastic protective layer, starting from the center of the patch. Try not to touch the adhesive side of the patch.
• Press this adhesive side 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 it sticks well, especially the edges.

Step 4: Removing the patch

• As soon as you remove the patch, fold it firmly in half so that the adhesive side sticks to itself.
• Put it back in its original pouch and dispose of it according to your pharmacist's instructions.
• Keep used patches out of sight and reach of children; even used patches contain medication that can harm children and even be fatal.
