Read this leaflet carefully before you start using this medicine, as it contains important information for you.

  • Keep this leaflet, as you may need to read it again.
  • If you have any questions, consult your doctor, pharmacist or nurse.
  • This medicine has been prescribed for you (or your child) only, and should not be given to others, even if they have the same symptoms as you, as it may harm them.
  • If you experience any side effects, consult your doctor, pharmacist or nurse, even if they are not listed in this leaflet. See section 4.

1. What is Durfenta and how is it used

This medication is called Durfenta

The patches help to relieve very strong and persistent pain:

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

Durfenta contains a medication called fentanil. It belongs to a group of strong pain-relieving medications called opioids.

2. What you need to know before starting to use Durfenta

Do not use Durfenta:

  • 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 Durfenta.

Warnings and precautions

  • Durfenta may have life-threatening adverse effects in people who are not regularly using prescribed opioids.
  • Durfenta is a medication that could be life-threatening to children, even if the patches have already been used. Note that a used or unused adhesive patch 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 should only be used 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 through 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 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 should be removed immediately and the person should seek medical attention.

Be especially careful with Durfenta

Consult your doctor or pharmacist beforeusing this medication if you are in any of the following circumstances. Your doctor will need 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 become weak and easily fatigued.

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

While using the patch, report to your doctor if you experience breathing difficulties while sleeping.Opioids like Durfenta 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 notice 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 adjust your dosage.

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

  • the patch no longer alleviates the pain
  • an increase in pain
  • a change in the way you feel 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 your dosage on your own. Your doctor may decide to adjust your dosage or change your treatment.

Side effects and Durfenta

  • Durfenta may make you feel exceptionally sleepy and cause your breathing to be slower or weaker. In rare cases, these respiratory problems can be life-threatening or even fatal, especially in people who have not used strong prescription opioids before (such as Durfenta or morphine). If you, or your partner, or caregiver notice 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
  • Have the person move and talk as much as possible
  • If you have a fever while using Durfenta, talk to your doctor. This may increase the amount of medication that passes through your skin.
  • Durfenta may cause constipation; talk to your doctor or pharmacist for advice on how to prevent or alleviate constipation.

See section 4 for the complete list of possible side 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, it may increase the amount of medication released from the patch.

Long-term use and tolerance

This medication contains fentanyl, an opioid. Repeated use of opioid pain relievers can make the medication less effective (your body becomes accustomed to it, known as pharmacological tolerance). It is also possible that you may become more sensitive to pain when using Durfenta. This is known as hyperalgesia. Increasing the dosage 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 dosage or gradually reduce your use of Durfenta.

Dependence and addiction

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

The repeated use of Durfenta may 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 dosage and longer use. Dependence or addiction may cause you to feel a lack of control over the amount of medication you should use or how often you should use it. You may feel the need to continue using the medication even if it no longer helps to alleviate pain.

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

  • You or any family members have abused alcohol or 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 symptoms while using Durfenta, it could be a sign of dependence or addiction:

  • You need to use the medication for a longer period than prescribed by your doctor.
  • You need to use a higher dosage 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 your 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 symptoms when stopping Durfenta

Do not stop using this medication abruptly. Withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heart rate (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 medication, talk to your doctor first. Your doctor will advise you on how to do it, usually by gradually reducing the dosage to minimize unpleasant withdrawal symptoms.

Other medications and Durfenta

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 Durfenta if you purchase any medication at the pharmacy.

Your doctor will know which medications can be taken safely with Durfenta. 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 dosage of Durfenta you need.

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

  • Other pain medications, such as other strong opioid pain relievers (e.g., buprenorphine, nalbuphine, or pentazocine)and some neuropathic pain medications (gabapentin and pregabalin).
  • Medications to help you sleep (such as temazepam, zaleplon, or zolpidem).
  • Medications to help you relax (tranquilizers, such as alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and medications for mental health conditions (antipsychotics, such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).
  • Medications to relax muscles (such as cyclobenzaprine or diazepam).
  • Some medications used to treat depression called SSRIs or SNRIs (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, or venlafaxine). – See below for more information.
  • Some medications used to treat depression or Parkinson's disease called MAOIs (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). Do not use Durfenta in the 14 days following the discontinuation of these medications. – See below for more information.
  • Some antihistamines, especially those that cause drowsiness (such as chlorpheniramine, clemastine, ciproheptadine, diphenhydramine, or hydroxyzine).
  • Some antibiotics used to treat infections (such as erythromycin or clarithromycin).
  • Medications used to treat fungal infections (such as itraconazole, ketoconazole, fluconazole, or voriconazole).
  • Medications used to treat HIV (such as ritonavir).
  • Medications used to treat irregular heartbeats (such as amiodarone, diltiazem, or verapamil).
  • Medications to treat tuberculosis (such as rifampicin).
  • Some medications used to treat epilepsy (such as carbamazepine, phenobarbital, or phenytoin).
  • Some medications used to treat nausea or dizziness (such as phenothiazines).
  • Some medications used to treat stomach acid or ulcers (such as cimetidine).
  • Some medications used to treat angina (chest pain) or high blood pressure (such as nicardipine).
  • Some medications used to treat blood cancer (such as idelalisib).

Using Durfenta with antidepressants

The risk of adverse effects increases if you are taking certain antidepressants. Durfenta may interact with these medications, 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 heart rate, high body temperature, hyperactive reflexes, lack of coordination, muscle stiffness, nausea, vomiting, and diarrhea (which may be signs of a serotonin syndrome). If you are taking these medications together, your doctor may want to monitor you closely to detect these side effects, especially when starting treatment or when changing the dosage of the medication.

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

The use of Durfenta with medications that have a sedative effect, such as benzodiazepines or related medications, increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and may be life-threatening. Therefore, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor prescribes Durfenta along with sedative medications, the dosage and duration of concomitant treatment should be limited by your doctor.

Please inform your doctor about any sedative medications you are taking, and followstrictlythe recommended dosage by your doctor. It may be helpful to inform friends or family members about the symptoms described above. Contact your doctor if you experience any of these symptoms.

Do not drink alcohol while using Durfenta, unless you have spoken with your doctor first.

Use in athletes

Inform athletes that this medication contains a component that may result in a positive analytical result for doping control.

Surgeries

If you think you will be receiving anesthesia, inform your doctor or dentist that you are using Durfenta.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication.

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

Durfenta should not be used during childbirth, as the medication may affect the newborn's breathing.

The prolonged use of Durfenta during pregnancy may cause withdrawal symptoms (such as loud crying, feeling restless, convulsions, poor feeding, and diarrhea) in your newborn, which may be potentially fatal if not recognized and treated. Talk to your doctor immediately if you think your newborn may have withdrawal symptoms.

Do not breastfeed while using Durfenta. Do not breastfeed for 3 days after removing the Durfenta patch. This is because the medication may pass into breast milk.

Driving and operating machinery

Durfenta may affect your ability to drive and operate machinery, as it may cause drowsiness or dizziness. If this is the case, do not drive or operate machinery. Do not drive while using this medication until you know how it affects you.

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