This medication is called Abattra.

• if you are allergic to fentanyl, soybean, peanuts, or any of the other ingredients in 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 usingAbattra.

Warnings and precautions

If the patch sticks to another person

The patch should only be used on the skin of the person to whom it was prescribed by the doctor. There have been some cases where the patch stuck accidentally to another person by close physical contact or sharing the same bed as the patch wearer. If the patch sticks accidentally to another person (especially a child), the medication from the patch can pass through the other person's skin and may cause serious adverse effects, such as difficulty breathing, slow or weak breathing that can be fatal. In the event that the patch sticks to another person's skin, remove it immediately and seek medical attention.

Be especially careful with Abattra

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 older 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 Abattra.

While using the patch, report to your doctor if you have breathing problems while sleeping.Opioids likeAbattracan 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 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 the dose on your own. Your doctor may decide to modify the dose or change the treatment.

Adverse effects and Abattra

• This medication may make you feel exceptionally sleepy and slow or weak breathing. In rare cases, these breathing problems can be life-threatening or fatal, especially in people who have not used strong prescribed opioids before. If you, or your partner, or caregiver, observe that the person wearing the patch is unusually sleepy, slow or weak breathing:

• 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 Abattra, talk to your doctor. This can increase the amount of medication that passes through your skin.
• This medication may 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.

Use in athletes

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

Symptoms of withdrawal when stopping Abattra

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 nauseous, 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 the dose will be gradually reduced to minimize unpleasant withdrawal effects.

Long-term use and tolerance

This medication contains fentanyl, an opioid medication. Repeated use of opioid analgesics can make the medication less effective (you become accustomed to it, known as medication tolerance). You may also become more sensitive to pain while using Abattra, known as hyperalgesia. Increasing the dose of the patches may help reduce pain for a while, but it can also be harmful. If you notice that your medication is becoming 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

The repeated use of this medication can also cause dependence, abuse, and addiction, which can lead to a potentially fatal overdose. The risk of these side effects may increase with a higher dose and longer duration of use. Dependence or addiction may make you feel like you no longer have control over the amount of medication you need to use or how often you need to use it. You may feel like you need to continue using your medication, even if it no longer helps to relieve your pain.

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

• You or someone in your family has ever abused or been dependent on alcohol, prescribed medications, or illegal drugs ("addiction").
• You are a smoker.
• You have ever had mood problems (depression, anxiety, or a personality disorder) or have been treated by a psychiatrist for another mental illness.

If you observe any of the following signs while using Abattra, it could be a sign that you have become dependent or addicted:

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

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

Other medications and Abattra

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 Abattra if you buy any medication from the pharmacy.

Your doctor will know which medications can be taken safely with Abattra. 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 Abattra you need.

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

• Other pain medications, such as other strong opioid analgesics (for example, buprenorphine, nalbuphine, or pentazocine) and some analgesics for neuropathic pain (gabapentin and pregabalin).
• Sleeping medications (such as temazepam, zaleplon, or zolpidem).
• Calming medications (tranquilizers, such as alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and medications for mental disorders (antipsychotics, such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).
• Muscle relaxants (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) - more information is below.
• Some medications used to treat depression or Parkinson's disease called MAOIs (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). Do not useAbattrain the 14 days following the interruption of these medications - more information is below.
• 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 infection (such as ritonavir).
• Medications used to treat irregular heartbeats (such as amiodarone, diltiazem, or verapamil).

Use of Abattra with antidepressants

The risk of adverse effects increases if you are taking certain antidepressants. Abattra 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, poor coordination, muscle stiffness, nausea, vomiting, and diarrhea (these may be signs of serotonin syndrome). If used together, your doctor may want to monitor you closely to detect such side effects, especially when starting treatment or when changing the dose of your medication.

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

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

However, if your doctor prescribes Abattra along with sedatives, your doctor should limit the dose and duration of concomitant treatment.

Inform your doctor about all sedatives you are taking and follow your doctor's recommendations closely. It may be helpful to inform friends or family members to be aware of the signs and symptoms mentioned above. Communicate with your doctor when you experience these symptoms.

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

Surgery

If you think you will receive anesthesia, inform your doctor or dentist that you are using Abattra.

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.

Abattra should not be used during pregnancy, except if you have talked to your doctor.

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

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

Do not use Abattra if you are breastfeeding. Do not breastfeed for 3 days after removing the Abattra patch. This is because the medication may pass into breast milk.

If you have applied too many patches or a patch with the wrong dose, remove them and contact your doctor immediately, go to the hospital or call the Toxicology Information Service at 91 562 04 20, indicating the medication and the amount applied.
