1. What is Abattra and what is it used for

This medicine is called Abattra.

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 need continuous pain treatment.

Abattra 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 Abattra

Do not use Abattra:

  • if you are allergic to fentanyl, soya, peanut, 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 this medicine.

Warnings and precautions

  • Abattra can have life-threatening side effects in people who are not regularly using prescribed opioids.
  • Abattra is a medicine that can be life-threatening to children, even if the patches have already been used. Note that an adhesive patch (used or unused) can 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 can be fatal.
  • Keep this medicine in a safe place, where other people cannot get to it, see section 5 for more information.

If the patch sticksto another person

The patch should only be used on the skin of the person it has been prescribed for. There have been reports of cases where the patch has stuck accidentally to another person through close physical contact or sharing the same bed as the patch wearer. If the patch sticks accidentally 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 that can be fatal. If the patch sticks to another person's skin, it should be removed immediately and medical attention should be sought.

Be especially careful withAbattra

Consult your doctor or pharmacist beforeusing this medicine if you are in any of the following situations. Your doctor will need to keep a closer eye on you:

  • 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 your muscles become weak and tire easily.

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

While using the patch, tell your doctor if you have breathing problems while you are asleep.Opioids like Abattra can cause sleep-related breathing disorders such as sleep apnea (pauses in breathing while asleep) 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 asleep;
  • waking up at night due to lack of breath;
  • 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 your pain;
  • an increase in pain;
  • a change in the way you feel pain (for example, you feel pain in a different part of your body);
  • pain when you touch your body that should not hurt.

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

Side effects andAbattra

  • This medicine can make you feel extremely sleepy and can slow down your breathing. In rare cases, these breathing problems can be life-threatening or even fatal, especially in people who have not used strong opioid painkillers before (such as Abattra 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 Abattra, talk to your doctor. This can increase the amount of medicine that passes through your skin.
    • This medicine can cause constipation; talk to your doctor or pharmacist for advice on how to prevent or relieve constipation.

You can find the complete list of possible side effects in section 4.

While 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 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.

Use in athletes

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

Withdrawal symptoms when stopping Abattra

Do not stop using this medicine suddenly. You may experience withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling sick, diarrhea, loss of appetite, tremors, chills, or sweating. 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.

Long-term use and tolerance

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

Dependence and addiction

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

Repeated use of this medicine can also lead to dependence, abuse, and addiction, which can result in a potentially fatal overdose. The risk of these side effects may increase with higher doses and longer use. Dependence or addiction can make you feel that you no longer have control over the amount of medicine you need to use or how often you need to use it. You may feel that you need to continue using your medicine, even when it no longer helps to 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 someone in your family has ever abused or been dependent on alcohol, prescription medicines, or illegal drugs ("addiction").
  • You are a smoker.
  • You have ever had problems with your mood (depression, anxiety, or a personality disorder) or have been treated by a psychiatrist for another mental illness.

If you notice 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 medicine for longer than recommended by your doctor.
  • You need to use more than the recommended dose.
  • 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 or control your use of the medicine.
  • When you stop taking the medicine, you feel unwell and feel better once you start taking the medicine again ("withdrawal symptoms").

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

Other medicines and Abattra

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 medicines. You should also tell your pharmacist that you are using Abattra if you buy any medicines from the pharmacy.

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

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

  • Other pain medicines, such as other opioid painkillers (e.g., buprenorphine, nalbuphine, or pentazocine) and some painkillers for nerve pain (gabapentin and pregabalin).
  • Medicines to help you sleep (such as temazepam, zaleplon, or zolpidem).
  • Medicines to help you calm down (tranquilizers, such as alprazolam, clonazepam, diazepam, hydroxyzine, or lorazepam) and medicines for mental health disorders (antipsychotics, such as aripiprazole, haloperidol, olanzapine, risperidone, or phenothiazines).
  • Medicines to relax your muscles (such as cyclobenzaprine or diazepam).
  • Certain medicines used to treat depression called SSRIs or SNRIs (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, or venlafaxine) - see below for more information.
  • Certain medicines used to treat depression or Parkinson's disease called MAOIs (such as isocarboxazid, phenelzine, selegiline, or tranylcypromine). You should not use Abattra in the 14 days after stopping these medicines - see below for more information.
  • Certain antihistamines, especially those that cause drowsiness (such as chlorphenamine, clemastine, ciproheptadine, 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 vomiting (such as phenothiazines).
  • Certain medicines used to treat heartburn or stomach 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).

Using Abattra with antidepressants

The risk of side effects increases if you are taking medicines such as certain antidepressants. Abattra 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 can 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 medicine.

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

Using Abattra 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 potentially fatal. Because of this, using them together should only be considered when other treatment options are not possible.

However, if your doctor prescribes Abattra together 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 instructions closely. It may be useful to inform friends or family members so they are aware of the signs and symptoms mentioned above. Contact your doctor when you experience these symptoms.

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

Operations

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

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.

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

Abattra should not be used during labor, as the medicine can affect the baby's breathing.

Long-term use of Abattra 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 Abattra if you are breastfeeding. You should not breastfeed for 3 days after removing the Abattra patch. This is because the medicine can pass into breast milk.

Driving and using machines

Abattra 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 unsure whether it is safe for you to drive while using this medicine.

  • Keep your child under close observation for 48 hours after:
  • Applying the first patch.
