1. What is Durfenta and what is it used for

This medicine is called Durfenta

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

• in adults who need continuous pain treatment
• in children over 2 years of age who are already using opioid medication and who need continuous pain treatment.

Durfenta contains a medicine called fentanyl. It belongs to a group of strong pain-relieving medicines called opioids.

2. What you need to know before you use Durfenta

Do not use Durfenta:

• If you are allergic to fentanyl or 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 an operation.
• If 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 Durfenta.

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 other person's skin and can cause serious side effects such as breathing difficulties, with slow or weak breathing, which can be life-threatening. If the patch sticks to another person's skin, it should be removed immediately and medical help should be sought.

Be careful with Durfenta

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.
• 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 an elderly person, as you may be more sensitive to the effects of this medicine.
• If you have a condition called "myasthenia gravis", where the muscles become weak and tired easily.

If you have any of the above conditions (or if you are not sure), consult your doctor or pharmacist before using Durfenta.

While using the patch, tell your doctor if you have breathing problems while sleeping.Opioids like Durfenta can cause sleep-related breathing disorders such as sleep apnea (breathing pauses while sleeping) and sleep-related hypoxemia (low oxygen levels 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
• 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 should be no pain.

Do not change the dose yourself. Your doctor may decide to change the dose or treatment.

Side effects and Durfenta

• Durfenta can make you feel extremely sleepy and can slow down your breathing. In rare cases, these breathing problems can be life-threatening, especially in people who have not used strong opioid painkillers before (such as Durfenta or morphine). If you, or 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
• Get the person to move and talk as much as possible

• If you have a fever while using Durfenta, talk to your doctor. This can increase the amount of medicine that passes through your skin.
• Durfenta 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 heat pads, electric blankets, hot water bottles, water beds, heat lamps or sunlamps. Do not take sunbaths or have long 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 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 Durfenta. 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 to increase the dose or gradually reduce the use of Durfenta.

Dependence and addiction

Repeated use of Durfenta 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 higher doses and longer use. Dependence or addiction can lead to a feeling of loss 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 Durfenta may be greater if:

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

If you notice any of the following symptoms while using Durfenta, 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 feel calm" or "to help you sleep".
• You have made repeated unsuccessful attempts to stop using the medicine or control your use.
• You feel unwell when you stop using the medicine, and you feel better once you start taking 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 the medicine, and how to do it safely.

Withdrawal symptoms when stopping Durfenta

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 to minimize unpleasant withdrawal effects.

Other medicines and Durfenta

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

Your doctor will know which medicines can be taken safely with Durfenta. You may need to be monitored closely if you are taking any of the following types of medicines, or if you stop taking any of the following types of medicines, as this can affect the dose of Durfenta that you need.

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

Using Durfenta with antidepressants

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

Using Durfenta with central nervous system depressants, including alcohol and some narcotics

Using Durfenta and medicines with a sedating effect, such as benzodiazepines or related medicines, increases the risk of drowsiness, breathing difficulties (respiratory depression), coma and can be life-threatening. Therefore, concomitant use should only be considered when other treatment options are not possible.

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

Please inform your doctor about any sedating medicines you are taking, and follow the dose recommended by your doctor strictly. It may be useful to inform friends or family members about the signs and symptoms described above. Contact your doctor if you experience any of these symptoms.

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

Use in athletes

Athletes are informed that this medicine contains a component that can result in a positive doping test.

Operations

If you are going to have an operation, tell your doctor or dentist that you are using Durfenta.

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.

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

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

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

Driving and using machines

Durfenta can affect your ability to drive or use machines or tools, as it can make you sleepy or dizzy. If this happens, do not drive or use machines or tools. 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 whether it is safe for you to drive while using this medicine.
