1. What Abattra is and what it is used for

This medicine is called Abattra.

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.

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

2. What you need to know before using Abattra

Do not use Abattra:

• if you are allergic to fentanyl, soy, peanut, or any of the other components of this medicine (listed in section 6);
• if you suffer from 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 is in any of the situations listed above. If you are unsure, consult your doctor or pharmacist before using Abattra.

Warnings and precautions

Abattra may have life-threatening adverse effects in people who are not regularly using prescribed opioids. Abattra 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 reports of cases in which the patch has accidentally adhered to another person through close physical contact or by sharing the same bed as the person wearing the patches. If the patch accidentally adheres to another person (especially a child), the medicine from the patch may pass through that person's skin and may cause serious adverse effects, such as difficulty breathing, slow or weak breathing, which could be fatal. If the patch sticks to another person's skin, remove it immediately and seek medical attention.

Take special care with Abattra

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 Abattra.

While using the patch, inform your doctor if you experience breathing problems during sleep. Opioids such as Abattra can cause sleep-related breathing disorders such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low blood oxygen levels). Talk to 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 your dose.

While using the patch, inform your doctor if you notice any 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 another part of your body);
• Pain upon 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 Abattra

• This medicine may make you unusually drowsy and may slow or weaken your breathing. In very rare cases, these breathing problems may be life-threatening or even fatal, especially in people who have not previously used strong opioid painkillers (such as Abattra 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.

• Encourage the person to move and speak as much as possible.

• If you develop a fever while using Abattra, speak with your doctor. This may increase the amount of medicine passing through your skin.

• This medicine 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.

Abattra, like other opioids, may affect the body's normal hormone production, such as cortisol, prolactin, or sex hormones, especially if Abattra has been used for long periods. The effects of these hormonal changes may include feeling unwell (including nausea and vomiting), 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 or tanning lamps. Do not sunbathe, take prolonged hot baths, or use saunas or hot tubs. Doing so may increase the amount of medicine released from the patch.

Use in athletes

Athletes should be aware that this medicine contains a component that may result in a positive analytical finding in doping controls.

Withdrawal symptoms when stopping Abattra

Do not stop using this medicine abruptly. Withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, awareness of heartbeat (palpitations), increased blood pressure, nausea or vomiting, 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.

Long-term use and tolerance

This medicine contains fentanyl, an opioid medicine. Repeated use of opioid painkillers may make the drug less effective (you become accustomed to it, known as drug tolerance). You may also become more sensitive to pain while using Abattra, a condition known as hyperalgesia. Increasing the patch dose may help reduce pain further for a time, but it may also be harmful. If you notice your medicine becomes less effective, talk to your doctor. Your doctor will decide whether it is better for you to increase the dose or gradually reduce the use of Abattra.

Dependence and addiction

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

Repeated use of this medicine may also lead to dependence, abuse, and addiction, which could result in a potentially fatal overdose. The risk of these side effects may increase with higher doses and longer duration of use. Dependence or addiction may make you feel that you no longer have control over how much medicine you need or how often you need to use it. You may feel that you need to continue using the medicine, even when it no longer helps relieve your pain.

The risk of becoming dependent or addicted varies from person to person. You may have a higher risk of becoming dependent or addicted to Abattra if:

• You or a family member has ever abused or been dependent on alcohol, prescription medicines, or illegal drugs ("addiction").
• You are a smoker.
• You have ever had mood disorders (depression, anxiety, or a personality disorder) or have been treated by a psychiatrist for a mental illness.

If you notice any of the following signs while using Abattra, it could indicate that you have become dependent or addicted:

• You need to use the medicine for longer than your doctor recommended.
• You need to use more than the recommended dose.
• You are using the medicine for reasons other than those prescribed, for example, "to stay calm" or "to help you sleep."
• You have made repeated unsuccessful attempts to stop or control your medicine use.
• When you stop taking the medicine, you feel unwell and feel better once you take it again ("withdrawal effects").

If you notice any of these signs, talk to your doctor to discuss the best treatment approach for you, including when it is appropriate to stop and how to stop safely.

Other medicines and Abattra

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicine.

This includes medicines obtained without a prescription and herbal remedies. You should also inform your pharmacist that you are using Abattra if you purchase any medicine from the pharmacy.

Your doctor will know which medicines can be safely taken with Abattra. You may need to be monitored 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 Abattra you need.

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

• Other pain medicines, such as other opioid painkillers (e.g., buprenorphine, nalbuphine, or pentazocine) and some neuropathic 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).
• Certain antidepressants known as SSRIs or SNRIs (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, or venlafaxine) – more information below.
• Certain medicines used to treat depression or Parkinson's disease called MAOIs (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). You must not use Abattra within 14 days of stopping these medicines – more information below.
• Certain antihistamines, especially those causing drowsiness (such as chlorpheniramine, clemastine, cyproheptadine, diphenhydramine, or hydroxyzine).
• Certain 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).
• Certain medicines used to treat epilepsy (such as carbamazepine, phenobarbital, or phenytoin).
• Certain medicines used to treat nausea or dizziness (such as phenothiazines).
• Certain medicines used to treat indigestion or ulcers (such as cimetidine).
• Certain medicines used to treat angina (chest pain) or high blood pressure (such as nicardipine).
• Certain medicines used to treat blood cancer (such as idelalisib).

Use of Abattra with antidepressants

The risk of adverse effects increases if you are taking medicines such as certain antidepressants. Abattra may interact with these medicines, and you may experience mental changes 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, overactive reflexes, lack of coordination, muscle rigidity, nausea, vomiting, and diarrhea (these may be signs of serotonin syndrome). If used together, your doctor may wish to monitor you closely for such side effects, especially when starting treatment or changing your medicine dose.

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

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

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

Inform your doctor about all sedative medicines you are taking and follow your doctor's recommendations closely. It may be helpful to inform friends or family members so they are aware of the signs and symptoms mentioned above. Contact your doctor if you experience these symptoms.

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

Surgery

If you are scheduled to receive anesthesia, inform your doctor or dentist that you are using Abattra.

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.

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

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

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

Driving and using machines

Abattra 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.

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

Abattra contains soybean oil

This medicine contains soybean oil. In very rare cases, soybean oil may cause allergic reactions.

It should not be used if you are allergic to peanuts or soybeans.

3. How to use Abattra

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

Before starting treatment and frequently during treatment, your doctor will also explain to you what to expect from using Abattra, when and for how long you should use it, when to contact your doctor, and when you should stop using it (see also section 2, Withdrawal symptoms when stopping Abattra).

Your doctor will decide which concentration of this medicine 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.

Where to Apply the Patch

Adults

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

Children

• Always apply the patch to the upper back so your child has difficulty reaching or removing it.

• Check regularly to ensure the patch remains adhered to the skin.

• It is important that your child does not remove the patch and put it in their mouth, as this could be life-threatening or fatal.

• Closely monitor your child for 48 hours after:

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

• The patch may take some time to reach its full effect. Therefore, your child may need additional painkillers until the patch becomes effective. Your doctor will explain this to you.

Adults and Children:

Do not apply the patch to

• The same site twice in a row.
• Areas that move a lot (joints), irritated skin, or skin with wounds.
• Hairy areas of skin. If there is hair, do not shave it (shaving may irritate the skin). Instead, cut the hair as close to the skin as possible.

How to Apply the Patch

Step 1: Prepare the Skin

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

Step 2: Open the Pouch

• Each patch is sealed in its own pouch.
• Open the pouch by tearing or cutting along the notches indicated by the arrows.
• Gently tear or completely cut the edge of the pouch (if using scissors, cut close to the sealed edge to avoid damaging the patch).

• Hold the two parts of the opened pouch and pull them apart.
• Remove the patch and use it immediately.
• Keep 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.
• Check that the patch is not damaged.
• Do not use the patch if it is split, cut, or damaged in any way.
• Never divide or cut the patch.

Step 3: Peel and Press

• Make sure the patch will be covered by loose clothing and do not apply it under tight or elastic fabric.
• Carefully peel off half of the shiny plastic protective layer, starting from the center of the patch. Avoid touching the adhesive surface of the patch.
• Press this adhesive part of the patch onto the skin.
• Remove the remaining part of the protective layer and press the entire patch onto the skin with the palm of your hand.
• Press firmly for at least 30 seconds. Ensure the patch is well adhered, especially around the edges.

Step 4: Disposing of the Patch

• Immediately after removing the patch, fold it in half with the adhesive side sticking to itself.
• Place it back into the original pouch and dispose of it according to your pharmacist's instructions.
• Keep used patches out of sight and reach of children; even when used, patches contain medication that could harm children and may even be fatal.

Step 5: Washing Hands

• Always wash your hands with water only after handling the patches.

More Information on Using Abattra

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 sports while wearing the patch.

• You may also swim with the patch in place, but:

  • Do not use hot whirlpool baths.
  • Do not cover the patch with elastic or tight fabrics.

• While wearing the patch, do not expose it to direct heat sources such as heating pads, electric blankets, hot water bottles, heated waterbeds, or heat or tanning lamps. Avoid prolonged sun exposure, hot baths, and saunas. Doing so could increase the amount of medication released from the patch.

How Long Do the Patches Take to Work?

• The first patch may take some time to reach its full effect.
• Your doctor may provide additional painkillers during the first few days.
• Afterwards, the patch should provide continuous pain relief, allowing you to stop taking other painkillers. However, your doctor may occasionally prescribe additional painkillers.

How Long Should You Use the Patches?

• This medicine is indicated for long-term pain. Your doctor will advise you on how long you may expect to use the patches.

If Pain Worsens

• If your pain suddenly worsens after applying the last patch, check the patch. If it is no longer adhering properly or has detached, replace it (see also section If the Patch Detaches).
• 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 right away, go to a hospital, or call the Toxicology Information Service at 91 562 04 20, stating the medication and amount applied.

Signs of overdose include difficulty breathing or weak breathing, fatigue, extreme drowsiness, inability to think clearly or to walk or speak normally, and dizziness, lightheadedness, or confusion. 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. Then resume changing the patch every 3 days (72 hours) as usual.
• If you are significantly delayed, contact your doctor, as you may need additional pain relief, but do not apply extra patches.

If the Patch Detaches

• If the patch falls off before it is time to change it, apply a new one immediately and record the date and time. Choose a new skin site:

  • On the trunk or arm.
  • On the upper back for your child.

• Inform your doctor about this and keep the new patch in place for another 3 days (72 hours) or for the duration your doctor advises, before changing the patch as usual.

• If patches tend to fall off 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 medicine, speak to your doctor first. Your doctor will guide 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 Abattra”.
• If you stop using the patches, do not restart them without first consulting your doctor. You may require a different dose when resuming treatment.

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